Description

201228994 VI. Description of the Invention: [Technical Field to Be Invented by the Invention] The present invention relates to a material nest (four) structural heat insulation (4), a mineral foam obtained by the poem obtaining the heat insulating material, and a method of manufacturing the same. [Prior Art] The demand for heat insulating materials is now substantially increased. Even, I believe that in France, the construction industry accounts for about 46% of total energy consumption and 25% of total carbon dioxide emissions. Energy efficiency adjustments can significantly reduce domestic energy consumption. In order to achieve these goals, not only must consumers change their living habits in depth, but they must also achieve basic innovations in the field of building insulation technology. Furthermore, in order to effectively implement the refurbishment of existing shared parking spaces, it is important that such novel technologies are easily implemented by the user while being economically in line with the family owner's budget. There should be a distinction between technologies dedicated to internal insulation and external insulation in adiabatic technology, especially in the context of refurbishment. Innovative construction techniques such as single-wall bricks and sandwich-type bearing panels containing a structure filled with a heat insulating material have also emerged. The insulation materials conventionally used in the above-mentioned thermal insulation technology are inherently subject to change: - minerals: glass wool, asbestos, vermiculite, _polymer: expanded polystyrene foam (EPS) and extruded polystyrene Baked foam (XPS), polyurethane foam (PU), polyisocyanuric acid ga foam (polyisocyanuric acid vinegar), 153561.doc 201228994 - pure natural source Or animal material: bulk cellulose or injectable cellulose, hemp, flax, wood (fiber, flake, board), straw, cork, cotton, coco, wool, duck feathers. Its inherent performance in terms of thermal insulation is characterized by the thermal conductivity λ. This coefficient is intended to be expressed in degrees Celsius or absolute temperature when the temperature difference between the two sides is equal to 1 degree, across the wall of the lm214. The lower the coefficient, the better the thermal insulation performance of the material. All previously mentioned materials have defects and usage restrictions. Asbestos, glass wool and warp stones tend to cause H loss over time. In addition, in order to meet the requirements of novel regulation of control energy efficiency (genus

Thermal Regulation), it is necessary to increase the material thickness to achieve this equivalent energy', thereby causing the problem of effective space loss (for example, for glass woven, etc., 400 mm thickness). Improvements in achieving their inherent efficiency by increasing the density of this type of material are still limited. Eight polymers having a thermal conductivity value in the lower range (the thermal conductivity value of polyisocyanuric acid 17 is 0.029) has a problem associated with the recycling of the problem, and it separates the polymer from the building material. Defects associated with the need for waste disposal. In addition, it causes fire resistance and may release toxic end-of-fog in the event of fire (particularly significant in PU foams). The natural source material that is derogatory has the effect of "changing" between one batch and the other and has durability problems caused by compression. B [ SUMMARY OF THE INVENTION For the sake of clarity in the following, the following conventions are employed: Unless otherwise stated, all weight percentages are expressed as the weight of dry matter in the composition I53561.doc 201228994. • Cement slurry: As used herein, cement slurry is intended to mean a plastic state composition obtained by the addition of at least one mineral hydraulic binder, water, and optionally a specific additive, calcium sulfate and a filler. • Aqueous Foam: As used herein, an aqueous foam is intended to mean a foam composed of at least one gas (especially two gas) and one solvent (which may be water). These foams do not contain any mineral binders. It is characterized by its initial expansion coefficient at the initial time, the initial expansion coefficient = the total volume of the initial time / the volume of the solution used to produce the foam. As used herein, the 'initial time' is intended to mean that the operator implements the gas supply for generating the foam, such as described in patent FR2913351 (Al). With respect to the inherent instability, it is characterized by its stability over time, usually measured by the half-life (i.e., the time required to obtain a semi-equivalent drainage of the entire liquid used to produce the foam). The stability of such foams can be improved by the appropriate choice of a combination of a surfactant and a foam stabilizer, which is stable (4), such as in the patent application and the patents WO/2008/020246, WO/2006/067064 and US 4,218,490. And scented alcohol, hydrophilic colloid, protein. • Mineral Foam: As used herein, a mineral foam is intended to mean at least one gas (especially air), at least one solvent (which may be water), at least one mineral water, in an amount as defined below. A foam of a hard binder and at least one filler (especially 153561.doc 201228994). Such foams (e.g., the aforementioned foams) will change over time and will only stabilize when the mineral binder has reacted to "freeze" the material structure. • Hardened Mineral Foam: As used herein, mineral foam is intended to mean that the reaction of the hydraulic binder (hydration) results in the "freezing" of the main structure of the mineral foam via the hydration of the hydrate network. The mineral foam finally obtained. The mineral foam also means a bee-like structural heat insulating material obtained by hardening a mineral foam. As an alternative to the present invention, a heat insulating material is obtained from the cement slurry by hardening a cement slurry mainly composed of two aluminum hydraulic binders containing a low-density hollow filler. • Gaoming hydraulic binder (abbreviated as AHB): As used herein, a high aluminum hydraulic binder is intended to mean a hydraulic binder comprising at least one phase selected from the group consisting of C3A, CA, ci2A7, CUA7CaF2, C4A3$ (Yee) Lemite), C2A(1_x)Fx (wherein χ belongs to [〇, 〗]), hydraulic amorphous phase, the hydraulic amorphous phase has a C/A molar ratio in the range of 〇3 to 15 and makes such The cumulative amount of Al2〇3 in the phase ranges from 3% by weight to 7% by weight, preferably from 7% by weight to 5% by weight, and more preferably from 20% by weight to 3% by weight based on the total weight of the hydraulic binder. In particular, the adhesive may optionally contain the following based on the total weight of the binder: _ 〇% by weight to 90% by weight. /. , preferably up to 7% by weight, more preferably up to 5% by weight and most preferably up to 40% by weight of sulphuric acid or sulphuric acid source, and 153,561.doc 201228994 - 〇% by weight to 10,000% by weight, preferably 〇% by weight To less than 5% by weight Portland cement. At the same time, hardened mineral foams based on hydraulic binders have been developed for various applications. Many patents describe in particular how to make bubble concrete by incorporating aqueous foam or by generating gas on site by means of aluminum metal decomposition. . Lightweight concrete having improved freeze-thaw resistance properties caused by absorption of stress in the bubble network and inhibiting crack propagation has been widely demonstrated and disclosed. Particular mention can be made of patent US 7,288,147. It is also known to use the lightweight cement described in the patent application US 2005/126781 to cement oil wells in unstable rocks and land, such as deep sea sedimentary environments. A hardened mineral foam obtained from a ettringite type binder (i.e., a mixture of high alumina cement and calcium sulfate) is known from GB-1,506,417. US-4,670,05 5 also describes binders based on aluminates and calcium sulphates. However, these adhesives are used to make a foam block mainly composed of calcium citrate having a very high density. Hardened mineral foams obtained from high alumina cement and a large amount of niobate are known from GB-1578470 and GB-2162506. The honeycomb material obtained after hardening such mineral foams has the defects of weak mechanical resistance properties and extremely high density. WOOO/23395 describes an aerated stucco composition which is predominantly calcium aluminate and which comprises a filler in the form of aggregates. The heat insulating material obtained by such compositions has an extremely high density and thus insufficient heat insulating performance. Document RU2305087 describes hardened mineral foams based on calcium aluminate, gypsum and sand. The thermal insulation materials obtained in this document have high thermal conductivity and high density. Hardened mineral foams have also been developed for fire protection applications where they provide significant advantages over materials containing organic base or polymer components due to their inherently non-flammable characteristics or to 153561.doc 201228994 to refractory biomass. . However, although these hardened mineral foams fully meet the fire protection requirements, their thermal conductivity values of 1 are still acceptable for adiabatic type applications. These adiabatic type applications need to be less than or equal to 〇2 W/m at 2 (rc). C 'is even better than or equal to Q"5 w/m, even lower than or equal to 0.08 W/m/C and optimally lower than or equal to 〇〇45 w/m ^ of thermal conductivity value. The cerium oxide-derived material acquires a property of 〇2 w/m (>c, as described in DE3227G79, which has a high density (lion to 600 kg/m3), weak mechanical properties and weak fire resistance. Low thermal conductivity materials are also described in EP 2 093 201. There are lime-based foams obtained from a mixture of hydraulic lime and cement. However, the use of hydraulic lime unfortunately results in the formation of products of very high density. Gaoshao Cement has also been described in Jp〇6〇56497 to obtain such thermal conductivity. However, these materials are essentially pumice-based and have a very high density (8 〇〇kg/m) due to lack of aeration. However, it is technically extremely difficult to maintain the material at 2 〇 <)(: obtain these thermal conductivity values) It has minimal mechanical properties and retains its physical integrity', ie the material does not collapse under its own weight. Furthermore, obtaining a material having a lower density than the prior art is also a problem solved by the present invention. Foaming of minerals based on hardened cement The intrinsic adiabatic performance of the material produced by the body will be higher 'this is because the bubble fraction of the (four) towel is purely high and the bubbles will be as small as possible and not connected to avoid the thermal bridge. However, the adiabatic properties are favorable for the given pore size distribution. An increase in pore volume also causes an increase in material fragility, which illustrates how the refractory hardened mineral foam reaches a limit. Finally, a method of making an adiabatic hardened mineral foam is described in the patent Ep 〇 153 561. doc 201228994 121 524 'This method includes providing An aqueous solution containing oxidized and partially accommodating acid is added to the aqueous hair/envelope/π via an aqueous solution of X I1 hair/encapsulated/3⁄4 polyvinyl alcohol produced by mechanical foaming with air, and a dispersing agent. By using polyvinyl alcohol and sodium metaborate or barium metaborate in combination, it is possible to provide a stable aqueous foam. The crosslinker' enables the size β of the bubbles included in the material to thus make the aqueous foam chemically stable. Therefore, it needs to be effective, easy to implement, and cost effective, while being safe and accessible to operators and users. A novel solution to the excellent trade-off between workability, mechanical properties, low density and thermal insulation. Applicants have unexpectedly discovered that certain high aluminum hydraulic binder compositions make it possible to use fine powders (especially in bubbling form) or Incorporating a large amount of air in the form of a low-density hollow filler and obtaining a material having a low thermal conductivity and a high mechanical strength, particularly a high compressive strength, after hardening the binder. Therefore, the honeycomb can be obtained from a hardened cement-based mineral foam. A structural material that has significant thermal insulation properties and also has sufficient short-term mechanical strength when used in many applications where it is particularly desirable to place the material in situ. These compressive strength values are not obtained when using an adhesive substantially made of Portland cement. The present invention relates to a honeycomb structural heat insulating material comprising the following materials based on the total weight of the material: a) 4% by weight to 96% by weight of a cement matrix obtained by hydration of a hydraulic binder, the hydraulic binder Characterized in that it comprises at least one phase selected from the group consisting of C3A, CA, C12A7, CllA7CaF2, C4A3$(Yee lemite), C2A(lx)Fx (where χ belongs to 153561.doc 10 201228994 [〇 before contact with water] , i]), a hydraulic amorphous phase having a C/Α molar ratio in the range of 〇3 to 15 and such that the cumulative amount of Al2〇3 in the phases is in the total weight of the hydraulic binder Between 3% by weight and 70% by weight, preferably 7% by weight to 5% by weight, and preferably 20% by weight to 3% by weight, b"% by weight to 96% by weight of at least one filler, preferably The material preferably has a lower than or equal to 〇2 w/m〇c at 2 (TC), preferably lower than or equal to G.15 W/m ° C, preferably lower than or equal to 〇Q8 w/me (:, even better, lower than or equal to 0.G45 W/mt and preferably lower than or equal to 导热4 W/m ° C. The thermal conductivity is preferably The binder of the material additionally comprises the following substances in terms of the total weight of the binder: 〇/〇 to 90 /〇, preferably up to 7〇%, even more preferably up to and optimally up to 40〇/. Calcium sulfate or calcium sulfate source And - 〇% to less than 5% of Portland cement. Preferably, the water-containing matrix accounts for 1% by weight to 80% by weight of the honeycomb structural insulating material and more preferably 20% ❶/〇 to 6〇0. As used herein, '"hydraulic binder hydration" is intended to mean that the hydraulic binder is in contact with water, and the weight ratio of water to hydraulic binder is usually from 〇1 to 0.7, preferably 〇.15 to The mineral foam of the present invention is prepared using water as a solvent and this weight ratio characterizes the mineral foam of the present invention. The hydration can be achieved as described in the preparation of the cement slurry as described below, or in the preparation The mineral foam is realized at any time by introducing water or an aqueous solvent. The present invention further relates to a method for producing a heat insulating material or a hardened mineral foam 153561.doc 201228994. The method comprises producing a mineral hair which will be described below. Bubble or contain low density a cement slurry of a hollow filler, and a coagulation or hardening step, which will take different time depending on the additive used. The present invention further relates to a mineral foam which enables a heat insulating material to be obtained after hardening, and the production of the mineral foam Further, the present invention relates to a cement slurry comprising a low-density hollow filler which enables a heat insulating material after hardening, and a method of manufacturing the same. In order to obtain a thermal conductivity value in accordance with an adiabatic type of application, not only It is necessary to form a very fine aqueous foam in an initial state, and it is also preferable to have a hydraulic substrate which enables a mineral foam which has sufficient workability on the one hand to allow placement thereof and another The hydrate network is developed very early in order to stabilize the mineral foam in a plastic configuration prior to the occurrence of the Ostwald ripening phenomenon. Applicants have found that the use of the high alumina hydraulic binder AHB is particularly well suited to obtain a compromise between the processability of the foam and the early development of the hydrate network. In an alternative embodiment, such a property can be obtained by using a low density hollow filler dispersed in a cement slurry mainly composed of the high alumina hydraulic binder AHB. In a preferred alternative, fillers selected from reactive fillers are used to modify these properties. These phases develop extremely high hydraulic potential after contact of the binder AHB with water, immediately causing a large number of small hydrates (which can have submicron to micron 153561.doc 201228994 small) nucleation, thus: - first stabilized The mineral foam makes it plasticized in a certain period of time (thus preventing Ostwald ripening), which can be adjusted according to the desired processability - it is between 5 minutes and 30 minutes, or even greater than 30 minutes; • Secondly' enables the formation of a mineral hydration skeleton via infiltration, which will ensure early mechanical performance and allow for the provision of the hardened mineral foam of the invention and/or the insulating material of the invention. Particular attention is paid to the use of a hydraulic binder comprising a source of calcium sulphate or calcium sulphate to promote the production of a mafic and hydrated alumina phase which has the advantage of enhancing the mechanical properties of the hardened mineral foam and also improving its fire resistance. These binders are especially important for providing high early mechanical strength. At 24 hours, the material of the present invention has a final mechanical strength of at least 8%, which is not the case when the binder is substantially made of Portland cement. These binders also enable control and restriction of shrinkage of the cured material. The use of the hydraulic binder AHB of the invention makes it possible to obtain hardened mineral foams which are free of polymers, in particular EPS, XPS, PU and PIR type polymers, which have the desired thermal conductivity. Nature and excellent fire resistance. Therefore, this type of hydraulic binder AHB enables improved fire resistance of the material, indicating a significant improvement over foams based on EPS, XPS, Pu and PIR type polymers. In addition, the use of this type of hydraulic binder AHB improves the production reliability of mineral foams under industrial conditions, which is less sensitive to Ostwald ripening 153561.doc 201228994 and because of surfactants and The optimization of the bubble stabilizer system thus becomes less important. As a non-limiting example, the adhesive of the present invention will be capable of containing high alumina cement and calcium sulphoaluminate type cement, and the latter cement will be available from a calcium sulphate source as appropriate. Non-limiting examples of commercially available Gaoshao cement include, for example, Secar 71, Secar 51, Fondu Cement, Ternal RG, Ternal EV sold by Kerneos, and high alumina sold by Calucem, Cementos Molins, and TMC and Denka of Japan. cement. Non-limiting examples of commercially available aluminum sulfate cements include, for example, Rapidset sold by CTS, ΑΙιρΓέ cement sold by Italcementi Corporation, and calcium sulphoaluminate sold by p〇iarbear & Li〇nhead. The high aluminum hydraulic binder A Η B of the present invention enables rapid development of a hydrate network due to its reactivity, which permeates, freezes the bubble diameter and forms a mineral skeleton of the hardened mineral foam. This phenomenon occurs regardless of the reagent used to obtain the aqueous foam, i.e., independent of the blowing agent, the gas carrier or the gas generating agent. As a matter of fact, it appears that the mechanism within the scope of the present invention corresponds to mineral stabilization achieved by the formation of hydrates in the early freezing of gas or air inclusions. Therefore, a hardened mineral foam having a very uniform distribution of small bubbles is obtained. Thus, the present invention differs from the hardened mineral foam compositions described in the prior art and in particular the patent ΕΡ 0 121 524 in terms of the particular choice of hydraulic binder. The fact is that the high reactivity of the mineral compounds used makes it possible to obtain a hardened mineral foam of good quality 15356I.doc 201228994 without using, for example, a polyvinyl alcohol + borate combination. Accordingly, the mineral foams and hardened mineral foams of the present invention and the honeycomb structural heat insulating material preferably do not contain a polyvinyl alcohol + borate combination. In contrast to prior art techniques for optimizing the surfactant system to limit Ostwald ripening, the invention thus enables early management of the condensation of the mineral system and in particular overcomes the increase in bubble size and thus the increase in thermal conductivity and mechanical Ostwald ripening with reduced strength. Aqueous foam stability or mineral hair obtained by correlation with surfactants and polymers or other aqueous foam stabilizers known to those skilled in the art, such as proteins or polymers of natural or synthetic origin. The stabilization of the hardened mineral foam or cement slurry obtained by the high reactivity of the hydraulic binder AHB associated with the calcium sulphate of the present invention, compared to the improvement of the foam stability, enables reliable and A hardened mineral foam having a fine and uniform bubble network is obtained in a stable manner, thereby being condensed, '. A honeycomb-like structural insulating material having a low thermal conductivity while retaining excellent mechanical strength characteristics is then produced. The hardened mineral foam of the present invention has a lower density associated with high mechanical strength than prior art mineral foams containing a large amount of phthalate. As an alternative to the present invention, porosity can be provided by the presence of a low density hollow filler in the cement slurry, optionally associated with aqueous foams. As an additional advantage that cannot be ignored, the system of the invention has excellent short-term mechanical strength (after 3 hours), in particular via the following values of compressive strength: - for materials having a lambda value below 0.08 W/mt, the CS value is above 0.2 MPa, Preferably, it is still 0.3 MPa, and even more preferably higher than or equal to 0.5 MPa, 153561.doc 15 201228994 - in the case where the λ value is in the range of 0.08 to 0.2 W/m ° C, the CS value is higher than 0.8 MPa, Preferably higher than 1 MPa and even better than 1.5 MPa. The system of the present invention is characterized by the following compressive strength values (after 24 hours): - for materials having a lambda value lower than 〇.〇8 W/nTC, the CS value is higher than 0.3 MPa, preferably higher than or equal to 0.5 MPa, - In the case where the λ value is in the range of 0.08 to 0.2 W/m ° C, the CS value is higher than 1 MPa, preferably higher than 1.5 MPa. The heat insulating material of the present invention is also characterized by a shrinkage value of less than 5 〇〇 Mm/m, preferably less than 400 μm/m, advantageously less than 300 μm/m, and even more preferably less than 200 μm/m. This shrinkage is measured according to the method taught by the NF ΕΝ 128 08-4 standard. This property advantageously provides excellent adhesion of the material of the invention to the wall for filling hollow building elements' and better stability over time. This property is especially important to avoid the formation of thermal bridges when placing foam on site: building renovation, composite panel construction. Finally, as a further advantage, the mineral foam of the present invention allows for adjustment of the setting time. This is advantageous in comparison with mineral foams which essentially develop Portland oil as a binder in the early development of very high hydrate nucleation. The time of the Portland cement-based mineral foam (without accelerator system) is usually more than 2 hours. The mineral foams and cement slurries of the present invention can have a processability as short as 5 minutes (rapid coagulation) or as long as 30 minutes. Therefore, the mineral foam of the present invention has a workability which can be easily adjusted to a value in the range of 5 to 30 minutes or even more than 3 〇 153561.doc • 16· 201228994 : value. The advantage of the adjustable condensing time is that it requires rapid condensing from (4) to 3G minutes when it is carried out, and more than 3G minutes or even over (8) hours or 2 hours for applications requiring on-site mineral foam placement. Long setting times can be advantageous. The core can be obtained by using a hydraulic binder to obtain a processability of more than 1 hour or even more than 2 hours' while at the same time after the processability period (4) to obtain kinetics for rapid mechanical performance. As is well known to those skilled in the art, the small hydrate precipitated during the processability period stabilizes the mineral foam without affecting its plastic characteristics. The trade-off between processability time and mechanical performance gain can be readily adjusted using an accelerator/blocker additive system known to those skilled in the art and described below.
