Abstract
The invention discloses inorganic composite thermal mortar, which comprises ordinary Portland cement, coal ash, glass beads, expanded perlite, polypropylene fibers, heavy calcium powder, ash calcium powder, mineral fibers and a composite additive. By adopting the invention, fireproof insulation layers are constructed on the wall space and the top surface of the building effectively, the heat insulation property of the building is greatly improved, energy consumption for heating in winter and cooling in summer is reduced, and the inorganic composite thermal mortar has the advantages of light density, small heat conductivity coefficient, high temperature resistance, fire resistance, safety use, environmental friendliness and durability. The inorganic composite thermal mortar is suitable for thermal insulation construction of wall spaces and roofs, such as reinforced concrete, concrete, aerated concrete blocks, clay bricks, steel structures and the like, and is also suitable for construction of fireproof insulation layers, such as underground garage, elevator wells, tube wells, cold storages and the like.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of inorganic compounding thermal insulation mortar.
Background technology
Building energy conservation is China's hot issue of present stage, the fire-retardant guarantee people's life of Building Fire Protection safety most important aspect, emerged in large numbers on the market and permitted eurypalynous lagging material.
Organic insulation material mainly comprises urethane, polystyrene foam, polymerization phenolic resin foam and rubber and plastic material foam material etc.Such material is according to low heat conductivity, lightweight, hydrophobic nature are used widely by force uniquely.But, because the inflammableness, particularly burning smoke coefficient of organic materials are large, toxicity large, environment is had significantly (directly with potential) severe contamination, be restricted in application.
Compare with organic insulation material, inorganic heat insulation material fire prevention, flame retardant resistance are strong, mostly are incombustible substance, and be nontoxic and safety coefficient is high, and this has just determined that inorganic heat insulation material is at the emphasis that will greatly develop from now on.Inorganic energy-saving and heat-insulating material is divided into the lagging material of loose fiber and goods (such as rock wool, slag wool and goods), porous particle dry-mix (the light-weight aggregate mortars such as glass bead, pearlstone) and mixed type.More than can both reach insulation and fp target, with regard to its weather resistance, only have high-quality dry-mix could with build the same longevity.
The thermal insulation mortar performance index mainly comprise workability physical and mechanical property thermal property flame retardant property and endurance quality etc.Dry-mix must keep heat-proof quality (the hot Xi Shuo of the average Dao of aglite＜=0.04W/m.k), further increase simultaneously the storage pore in the course of processing, reduction density, raising heat insulation and preservation effect of some extraordinary raw material.Become a kind of solid of porous network structure of sealing behind the requirement mortar construction drying and moulding
Summary of the invention
The object of the present invention is to provide a kind of can Effective Raise the inorganic compounding thermal insulation mortar of the fire-resistant and heat-insulating property of buildings.
The inorganic compounding thermal insulation mortar that the present invention proposes; it is characterized in that being formed by ordinary Portland cement, flyash, glass bead, pearlstone, polypropylene fibre, dicalcium powder, grey calcium powder, ore deposit fiber, compound additive; compound additive mainly is mixed in proportion by redispersable latex powder, ether of cellulose, HPMC, sepiolite, diatomite, hydrophober, air entrapment agent and forms
The ratio of each component is:
Ordinary Portland cement 350 ~ 400,
Flyash 100 ~ 150,
Glass bead 120 ~ 150,
Pearlstone 250 ~ 270,
Polypropylene fibre 4 ~ 6,
Dicalcium powder 10 ~ 30,
Ash calcium powder 10 ~ 30,
Ore deposit fiber 2 ~ 4,
Compound additive 15 ~ 20.
Wherein compound additive is: redispersable latex powder 50%, ether of cellulose 15%, HPMC15%, sepiolite 5%, diatomite 5%, hydrophober 5%, air entrapment agent 5%,
The ratio of each component is:
Ordinary Portland cement 360 ~ 400,
Flyash 100 ~ 120,
Glass bead 120 ~ 150,
Pearlstone 250 ~ 270,
Polypropylene fibre 4 ~ 6,
Dicalcium powder 15 ~ 30,
Ash calcium powder 15 ~ 30,
Ore deposit fiber 2 ~ 3,
Compound additive 16 ~ 20.
The preparation method of inorganic compounding thermal insulation mortar of the present invention sequentially adds and opens fly cutter and stirred 2 minutes by cement, flyash, dicalcium powder, grey calcium powder, polypropylene fibre, ore deposit fiber, stops fly cutter again and adds fast all the other components and stir and make dry-mixed mortar.
Characteristics of the present invention and advantage:
The present invention in use allocates stirring by the cement-water ratio of 0.95 ~ 1.0:1 can obtain the suitable wet mortar of denseness, leaves standstill after stirring to re-use in 10 minutes, finishes using in 3 ~ 4 hours.Exceed duration of service and land mortar and can not continue upper wall and use.
Ordinary Portland cement is as inorganic coagulation material among the present invention, can with the reaction of steeping in water for reconstitution unboiled water, produce spawn, aggregate is together cementing, produce certain intensity, redispersable latex powder in the compound additive, ether of cellulose, HPMC can further improve the bonding strength of microcosmic and macroscopic view, and hydrolysis product of cement solidifies rear and metope, roofing or generation chemistry of the bonding mortar on it and physical action simultaneously, and what be coheres more firm with walls and roofs.Flyash contains and floats in a large number pearl particle and SiO
2And Al
2O
3Active goods and materials replace the part gelling material to reduce slurry density.Glass bead and pearlstone are the aggregates in the mortar, and thermal conductivity is low, can high temperature resistantly not burn, indeformable, not explosion.The adding of ash calcium and dicalcium powder is conducive to improve the workability constructability of mortar.The draining that the adding of polypropylene fibre increases mortar forms the resistance to cleavage that the macro mesh structure increases mortar simultaneously.The air entrapment agent effect is and can introduces certain bubble by mortar in whipping process, increase agglutinating value(of coal) and application property, the adding of ore deposit fiber and sepiolite can improve the microstrength of mortar, the bubble that forms a large amount of small and disperseds with the acting in conjunction of HPMC consists of small insulated space, further reduces thermal conductivity and has eliminated simultaneously because forming air pocket to the destruction of mortar strength and forming pore and increase transmission of heat by convection.
The present invention adopts the fabulous glass bead of fire resistance and pearlstone, rational proportion gelling material, fiber, compound, and admixture is the thermal insulation mortar of a kind of lightweight, fire prevention, low thermal conductivity, higher-strength, its method of supplying is the bag packing dry powder.Allocate stirring by the cement-water ratio of 0.95:1 in the use and can obtain the suitable wet mortar of denseness.Through check, tap density≤250kg/m of the present invention
3, dry apparent density≤300kg/m
3, thermal conductivity≤0.050W/m.K, ultimate compression strength 〉=0.50MPa presses and cuts cohesive strength 〉=50kPa, and hollowing does not ftracture, and intensity is high, and adhesiveproperties is good, and has resistance to deterioration and fire resistance and environment-friendly function.
In sum, because the above-mentioned beneficial effect that the present invention has, so the thermal-insulation energy-conservation effect is remarkable, pi of strength is superior, has saved to a greater degree building energy consumption, is not only applicable to New Buildings, and is applicable to the existing building reducing energy consumption.The present invention can substitute traditional mixing motar, again can be with the heat preservation construction of good sticking heat-preservation plate combined wall that can the heat insulation effect replace complex.Constructing operation of the present invention is easy, and technical requirements is not high, and quality control is easily gone, and can greatly improve operating efficiency, is convenient to large-scale promotion application.
