Definitions
- thermosetting aqueous binder based on water-soluble oligomeric esters obtained by reaction between a carbohydrate, a diol and a polycarboxylic acid.
- binder for binding organic or mineral fibers together, preferably mineral wool fibers, in particular glass or rock wool.
- thermosetting binders for mineral wools or nonwoven products based on mineral fibers It has been known for several years to use aqueous compositions based on biobased reagents, in particular based on sugars, as thermosetting binders for mineral wools or nonwoven products based on mineral fibers.
- thermoset polyesters by reacting reducing sugars and/or non-reducing sugars and/or hydrogenated sugars, bearing hydroxyl groups, with polycarboxylic acids in the presence of a catalyst, generally hypophosphite sodium (WO 2009/080938, WO 2010/029266, WO 2013/014399, WO 2013/021112).
- a catalyst generally hypophosphite sodium (WO 2009/080938, WO 2010/029266, WO 2013/014399, WO 2013/021112).
- compositions based on oligomeric and/or polymeric carbohydrates (dextrose equivalent 2 - 20) and a crosslinking agent chosen from polycarboxylic acids. These compositions also contain an oligoester with an average mass by weight of between 1500 and 5000, obtained by reaction of polycarboxylic acid and glycerol.
- the sizing compositions described in the aforementioned documents are dilute, low-viscosity aqueous solutions of monomer reagents. They are generally sprayed on mineral fibres, which are still hot, immediately after they have formed. Immediately after application of the sizing composition to the fibers, the evaporation of the aqueous phase begins. When the fibers are collected and assembled in the form of a mattress on the collecting belt, they are sticky and the film of sizing composition which envelops the glass fibers still contains water.
- Heating the mat of bonded fibers to high temperatures for a few tens or hundreds of seconds results in the crosslinking of the reactive system by esterification and the formation of a water-insoluble binder, but also results in the thermal decomposition of part of the reactants and the evaporation of the decomposition products formed.
- the gaseous components formed in the oven are partially evacuated via the chimney (stack).
- the exhaust gases, or smoke, are treated in a washing system and the washing water is then recirculated in a closed system.
- the fumes When the sizing composition contains citric acid, the fumes contain many acid compounds (citric acid, citraconic acid, itaconic acid, proprionic acid, acetic acid, formic acid) which must be neutralized by adding bases, in order to prevent deterioration by corrosion of the installation. Adding bases is problematic, however. Indeed, in facilities manufacturing mineral wool-based insulation products, washing water is reinjected into the system, and is used in particular for the preparation of binder and sizing compositions. The presence of bases or salts in large quantities in the sizing compositions is likely to increase the pH and disturb the esterification reaction (crosslinking).
- oligomers has made it possible to significantly reduce the temperature at which the reactive system begins to crosslink and/or to shorten, for a given oven temperature, the time required for satisfactory hardening of the binder.
- Too much stickiness of the film of concentrated binder composition results, firstly, in reduced re-expansion of the mattress after compaction (roller) and, secondly, in difficult spreading and insufficient migration of the sizing composition towards the points. contact between mineral fibers.
- the insulation product obtained after curing the adhesive film then has a higher density and poorer mechanical properties than an equivalent insulation product obtained with a less viscous sizing composition, for a given solids content.
- the present invention is based on the discovery that the partial replacement of the carbohydrate(s) by a diol makes it possible to significantly limit, for a given conversion rate and dry matter content, the viscosity of the aqueous compositions of oligoesters. It thus becomes possible to synthesize less viscous oligoesters for a given conversion rate or else oligoesters containing, for a given viscosity, fewer free carboxylic acid functions.
- a higher conversion rate translates into an additional reduction of acid degradation products in chimney flue gases and a reduction in the crosslinking start temperature.
- the present invention firstly relates to a thermosetting binder composition containing water and a water-soluble oligomeric ester.
- - at least one carbohydrate chosen from reducing sugars, non-reducing sugars and hydrogenated sugars the hydrogenated sugars being chosen from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol and the hydrogenation products of starch hydrolysates or hydrolysates of lignocellulosic materials,
- the binder composition having a solids content of between 40% and 80% by weight, preferably between 40% and 70% by weight, the water-soluble oligomeric ester representing at least 70% by weight of the solids of the thermosetting binder composition, and the ratio of the number of hydroxyl groups of all the diols to the number of hydroxyl groups of all the diols and carbohydrates being between 5% and 50%.
- carbohydrate also encompasses non-reducing sugars consisting of several carbohydrate units, the carbons carrying the hemi-acetalic hydroxyl of which are involved in the osidic bonds linking the units together.
- binder composition designates concentrated aqueous solutions, that is to say with a high solids content (several tens of percent). These compositions can be stored and transported. They are fluid enough to be pumped, but too viscous to be sprayed on the fibers as they are.
- sizing composition refers to considerably less concentrated aqueous solutions having a solids content of less than 10% by weight. They are generally obtained by diluting the binder compositions with water. They have sufficiently low viscosities to allow their application to mineral wool fibers by spraying using nozzles.
- thermosetting binder compositions of the present invention in principle any carbohydrate chosen from reducing sugars, non-reducing sugars and hydrogenated sugars.
- hydrogenated sugar is meant all the products resulting from the reduction, or hydrogenation, of a saccharide (carbohydrate) chosen from monosaccharides, disaccharides, oligosaccharides and polysaccharides and mixtures of these products. Hydrogenated sugars are also called sugar alcohols, alditols or polyols. They can be obtained by catalytic hydrogenation of saccharides. The hydrogenation can be carried out by known methods operating under conditions of hydrogen pressure and elevated temperature, in the presence of a catalyst chosen from the elements of groups IB, IIB, IVB, VI, VII and VIII of the periodic table. elements, preferably from the group comprising nickel, platinum, palladium, cobalt, molybdenum and mixtures thereof.
- the preferred catalyst is Raney nickel.
- the hydrogenated sugar(s) are selected from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol, and the products of hydrogenation of starch hydrolysates or of hydrolysates of lignocellulosic materials, in particular of hemicellulose, in particular of xylans and xyloglucans.
- the hydrogenated sugars used in the present invention therefore do not include glycerol or polyglycerol.
- Starch hydrolysates are products obtained by enzymatic and/or acid hydrolysis of starch.
- the preferred starch hydrolysates have, before the hydrogenation step, a dextrose equivalent (DE) of between 5 and 99, and advantageously between 10 and 80.
- DE dextrose equivalent
- a hydrogenated sugar chosen from the group formed by maltitol, xylitol, sorbitol and the products of hydrogenation of starch hydrolysates or of lignocellulosic materials will be used in a particularly preferred manner.
- sorbitol is the most readily available on the market and the cheapest.
- the Applicant during its tests aimed at developing binders based on polycarboxylic acids and hydrogenated sugars, however found that this hydrogenated sugar, when used as such, did not easily allow the production of insulating products having satisfactory mechanical properties (tensile strength, recovery of thickness, bending strength). To give the insulating products obtained a certain mechanical strength, it was necessary to considerably increase the polycarboxylic acid/sorbitol ratio of the sizing compositions.
- the present invention makes it possible to avoid the disadvantages described above associated with the use of sorbitol as hydrogenated sugar. Indeed, the pre-oligomerization of sorbitol in an anhydrous medium in the presence of polycarboxylic acids gives oligoesters which have properties equivalent to those based on xylitol or maltitol for example.
- the binder composition and the sizing composition of the present invention therefore contain less than 10% by weight, preferably less than 5% by weight, even more preferably less than 2% by weight of free sorbitol, added after the esterification step or unreacted during esterification. These percentages of free sorbitol are related to the total solids content of the binder composition or the sizing composition of the present invention.
- the reducing sugars are preferably chosen from monosaccharides such as glucose, galactose, mannose and fructose, disacharides such as lactose, maltose, isomaltose and cellobiose, starch hydrolysates having a DE between between 5 and 98, preferably between 15 and 95 and hydrolysates of lignocellulosic materials.
- Glucose and fructose, in particular glucose will preferably be used.
- the non-reducing sugars are preferably disaccharides such as trehalose, isotrehaloses, sucrose and isosucroses. Sucrose is particularly preferred.
- the polycarboxylic acid(s) used in the present invention are monomeric polycarboxylic acids. In other words, in the present invention this term does not encompass the polymers obtained by polymerization of monomeric carboxylic acids, such as homopolymers or copolymers of acrylic acid or of methacrylic acid.
- polycarboxylic acids selected from the group consisting of dicarboxylic acids, tricarboxylic acids and tetracarboxylic acids will be used.
- the particularly preferred polycarboxylic acid is citric acid.
- the Applicant has carried out numerous tests to determine the respective proportions of carbohydrate and polycarboxylic acid which result in binders which, in the crosslinked state, give the final glass wool product the best mechanical properties, in particular after accelerated aging in wet conditions.
- carbohydrate/citric acid weight ratio is advantageously between 20/80 and 55/45, preferably between 25/75 and 50/50.
- the ratio of the total number of acid groups carried by the polycarboxylic acid to the total number of hydroxyl groups carried by the carbohydrate(s) and the diol(s) is advantageously between 30/70 and 70/30, preferably between 35 /60 and 60/40, in particular between 40/60 and 55/45.
- the diols used in the present invention to reduce the viscosity of the binder after application to the fibers and thus limit the stickiness of the mat before curing are preferably linear or branched aliphatic diols, and therefore do not include aromatic diols or cycloaliphatic diols.
- the diols are advantageously aliphatic diols comprising from 2 to 12 carbon atoms, preferably from 2 to 8 carbon atoms.
- the alkyl chain can contain one or more oxygen atoms.
- diols of those chosen from the group consisting of ethylene glycol, propylene glycol, butanediol, hexanediol, diethylene glycol and triethylene glycol.
- the quantity of diol(s) used is such that the ratio of the number of hydroxyl groups of all the diols to the number of hydroxyl groups of all the diols and carbohydrates is between 5% and 50%. Below the lower limit of this range, the technical effect (limitation of the increase in viscosity and reduction in tackiness) is insufficient. Beyond the upper limit of this range, it will certainly be difficult to obtain crosslinked binders in a satisfactory manner.
- the introduction of diols (difunctional compound) in a system based on citric acid and carbohydrates in fact reduces the average functionality of the reaction system.
- the ratio of the number of hydroxyl groups of all the diols used to the number of hydroxyl groups of all the diols and carbohydrates is advantageously between 8% and 40%, preferably between 10 and 30%. These percentages obviously apply to the diols and carbohydrates present in the reaction mixture before the esterification step implemented for the synthesis of the oligoester.
- the process for preparing the binder composition of the present invention comprises a step of synthesizing the oligomers by esterification of the reactants in an essentially anhydrous medium, then a step of diluting the reaction product formed with water.
- the process for preparing the binder compositions of the present invention comprises
- - heating a mixture of at least one carbohydrate chosen from reducing sugars, non-reducing sugars and hydrogenated sugars, at least one diol, at least one polycarboxylic acid and optionally at least one esterification catalyst, at a temperature of between 105°C and 170°C, preferably between 120 and 150°C, for a time of between 5 minutes and 10 hours, preferably between 20 minutes and 5 hours, in particular between 30 minutes and 2 hours, so as to form an oligomeric ester, and
- the reaction mixture of this bulk polycondensation is preferably essentially anhydrous, that is to say it preferably contains less than 2% water, preferably less than 1% water. In some cases, it may be necessary or acceptable to add a small amount of water, generally less than 10% by weight, in order to homogenize the reactants in the reaction mixture. This water necessary for homogenization then evaporates under the effect of heating.
- a preferred embodiment of the oligoester synthesis process comprises heating the carbohydrate and the diol, in the absence of solvent, until complete fusion, then adding citric acid and, if necessary, the catalyst. The reaction times depend on the evolution of the viscosity of the medium during the synthesis.
- the degree of progress of the oligomerization reaction can be monitored as follows by viscometry: An aliquot of the reaction medium is taken and diluted with distilled water so as to obtain a solution having a solids content (extract dry) equal to 60%. This solution is introduced into an Anton Paar MCR302 rheometer with a 50 mm cone-plane upper geometry and a 50 mm plane lower geometry which allows high sensitivity to low viscosities. The viscosity of the oligomers is measured at ambient temperature for shear rates increasing from 5 s ⁇ 1 to 1000 s ⁇ 1 , then decreasing again from 1000 s ⁇ 1 to 5 s ⁇ 1 . It can be seen that the viscosity does not depend on the shear rate. The solutions of the oligomers are therefore Newtonian liquids. The values of the viscosities are recorded at 20° C. at a shear rate of 100 s ⁇ 1 .
- the objective of the study of the kinetics of the oligomerization reaction is to find the best compromise between, on the one hand, an acceptable viscosity, that is to say a viscosity low enough for the binder compositions , fairly concentrated, remain pumpable, and, on the other hand, the lowest possible crosslinking start temperature.
- the crosslinking onset temperature is determined by dynamic thermomechanical analysis (DMTA, from the English Dynamic Mechanical Thermal Analysis) which makes it possible to characterize the viscoelastic behavior of a polymeric material.
- DMTA dynamic thermomechanical analysis
- Two strips of glass microfiber paper are cut and superimposed.
- Thirty milligrams of binder composition having a solids content of 30% are deposited homogeneously on the strips which are then fixed horizontally between two jaws of an RSAIII device (Texas Instrument).
- An oscillating element provided with a device for measuring the stress as a function of the deformation applied is arranged on the upper face of the sample.
- the device allows the modulus of elasticity E' to be determined.
- the sample is heated to a temperature varying from 20 to 250°C at the rate of 4°C/min. From the measurements, the curve of variation of the modulus of elasticity E' (in MPa) as a function of the temperature (in °C) is established.
- DMTA curves are modeled as three line segments: (1) tangent to the curve before the start of the reaction,
- the crosslinking onset temperature (TR) is the temperature at the intersection of the first two straight lines.
- the heating is stopped and water is added to the reaction mixture so as to obtain the binder compositions of the present invention.
- the binder composition of the present invention generally contains less than 25% by weight, preferably less than 20% by weight, based on solids content, of free residual polycarboxylic acid.
- the other two types of monomers, namely carbohydrates and diols, are preferably present only in trace amounts, for example in amounts of less than 5% by weight, preferably less than 2% by weight.
- the viscosity of the binder compositions is between 50 and 250 mPa.s, preferably between 60 and 200 mPa.s, in particular between 70 and 180 mPa.s.
- Bulk oligomerization can be carried out in the presence of a known esterification catalyst chosen, for example, from strong acids such as sulfuric acid, hydrochloric acid, para-toluenesulfonic acid, trifluoromethanesulfonic acid and trifluoroacetic acid, and Lewis acids commonly used for the catalysis of esterification reactions.
- a known esterification catalyst chosen, for example, from strong acids such as sulfuric acid, hydrochloric acid, para-toluenesulfonic acid, trifluoromethanesulfonic acid and trifluoroacetic acid, and Lewis acids commonly used for the catalysis of esterification reactions.
- the bulk oligomerization reaction when using citric acid, can also be catalyzed by sodium hypophosphite which is not strictly speaking an esterification catalyst, but which is thought to promote the formation of citric anhydride which is more reactive than the triacid and capable of reacting with polyols (carbohydrates and diols).
- thermosetting binder composition One or other of these two types of catalysts will therefore be present in the thermosetting binder composition.
- an esterification catalyst such as a strong acid
- sodium hypophosphite and the corresponding acid are indeed, to date, the compounds which most effectively catalyze the hardening of oligomers into a thermoset binder, insoluble in water.
- binder compositions of the present invention must be capable of being stored and transported, that is to say they must be stable on storage at room temperature and not undergo substantial hydrolysis of the oligoesters into polyols and polyacids, despite the presence of quantities relatively large amounts of water, which can range from 20 to 60% by weight.
- compositions had a neutral or acid pH, preferably between 1 and 7, more preferably between 3 and 6.
- the present application also relates to a process for manufacturing a product based on mineral or organic fibers bound by an insoluble organic binder, using a binder composition according to the invention as described above.
- This process comprises the following successive steps:
- the sizing composition To obtain good quality products, it is necessary for the sizing composition to have good sprayability and to be able to deposit in the form of a thin film on the surface of the fibers in order to bind them effectively.
- the sprayability of the sizing composition is directly related to the possibility of diluting the concentrated binder composition with a large amount of water.
- the diluted sizing composition must be a solution, stable over time, which does not give rise to demixing phenomena.
- the aptitude for dilution is characterized by the "dilutability" which is defined as being the volume of deionized water which it is possible, at a given temperature, to add to a unit volume of the binder composition before the appearance of a permanent disorder. It is generally considered that a binder composition is suitable for use as a size when its dilutability is equal to or greater than 1000%, at 20°C.
- the binder compositions of the present invention have a dilutability greater than 2000%.
- the step of preparing the sizing composition advantageously comprises the addition of one or more known additives commonly used in the technical field of mineral wool. These additives are chosen for example from anti-dust additives, silicones and coupling agents.
- the binder composition large quantities of monomers capable of reacting with the oligoesters, such as reducing sugars, non-reducing sugars, sugars hydrogenated, or other polyols, or even amines, in particular alkanolamines.
- monomers capable of reacting with the oligoesters such as reducing sugars, non-reducing sugars, sugars hydrogenated, or other polyols, or even amines, in particular alkanolamines.
- the sizing composition when it is applied to mineral or organic fibers, therefore preferably comprises at least 70% by weight, more preferably at least 75% by weight, or even at least 80% by weight, based on its total solids content of water-soluble oligomeric ester.
- the fibers are mineral fibers and the assembly of fibers is mineral wool.
- the application of the sizing composition to the mineral fibers is done in a known manner by means of nozzles arranged on spray crowns close to the devices for extruding the molten glass.
- the glued mineral fibers are then gathered in the form of a mat (loft) on a conveyor belt which passes through the oven.
- the assembly of sized mineral fibers is advantageously heated for a period of between 20 seconds and 5 minutes, preferably between 30 seconds and 3 minutes at a temperature of between 180 and 230°C.
- the degree of conversion of the oligomerization (esterification) reaction is monitored by acid-base titration: an aliquot of the reaction medium (approximately 1.0 g) is taken and diluted with distilled water so as to obtain a solution having a dry matter content of about 1%.
- the number of residual acid functions in the aliquot taken is determined by pH-metry using an automatic titrator (addition of 0.1 N NaOH), then the number of residual acid functions in the reaction product is calculated.
- the viscosity of the reaction product diluted to 60% dry matter is determined using an Anton Paar MCR302 rheometer with an upper cone-plane geometry 50 mm and a lower plane geometry 50 mm which allows great sensitivity to low viscosities.
- the viscosity of the oligomers is measured at room temperature for shear rates increasing from 5 s -1 to 1000 s -1 , then decreasing again from 1000 s -1 to 5 s -1 . It can be seen that the viscosity does not depend on the shear rate.
- the solutions of the oligomers are therefore Newtonian liquids.
- the values of the viscosities recorded at 20° C. at a shear rate of 100 s ⁇ 1 are collated in table 1 below.
- the viscosity of the binder compositions decreases when part of the sorbitol is replaced by butanediol.
- the viscosity of a binder composition prepared from sorbitol and citric acid and having a conversion rate of 38% is 95 mPa.s.
