Abstract
The invention discloses an inorganic insulation composite material for building energy-saving wall and a preparation method thereof. The inorganic insulation composite material for building energy-saving wall provided by the invention is composed of the following raw materials, by weight: 40-50 parts of silica aerogel, 10-20 parts of expanded perlite, 5-10 parts of clay and 5-10 parts of glass fiber. The above materials and liquid water glass 2-5 wt% of the composite material are mixed by stirring, and pressed to obtain the insulation composite material for wall. The inorganic insulation composite material for building energy-saving wall provided by the invention has advantages of excellent thermal insulation properties and mechanical properties, good waterproof and flame retardant performance, good weather resistance, green and environment-friendliness.
Description
Technical field
The present invention relates to heat-insulating composite material, relate to particularly the external-wall heat-insulation material of aerosil and inorganic building material preparation.
Background technology
At present although thermal and insulating performance is good, also there is critical defect take the styrofoam of organic, urethane etc. as main in the wall thermal insulating lagging material of domestic construction thing.Organic heat-insulating lagging material weathering resistance is poor, and especially fire resistance does not reach national fire protection requirement, consequence that especially can bringing on a disaster property after Highrise buildings uses.Beijing " CCTV's fire ", Shanghai " 11.15 " fire in 2009 all are to have used the organic heat preserving and insulating material.Under the serious situation that current organic heat-insulating lagging material frequently catches fire, how to solve performance of heat protective material and the lagging material contradiction between catching fire, in the urgent need to a kind of novel heat preserving and insulating material, the demand of satisfying the market.Aerosil, it is a kind of novel nano hole inorganic materials, this material has high porosity (80%-99.8%), low density (0.03-0.3g/cm
3), the high-performance such as low-thermal conductivity (0.013-0.018 w/mk), low-k (1.0-2.0), aerosil is a kind of heat insulating material, its unit weight is ultralight, thermal conductivity is little, excellent thermal insulation performance, and fire resistance is good.But owing to be subject to the restriction of material choice, preparation technology, formulation parameter, product cost, make aerogel also have the problems such as the too high and Architectural Construction of cost is unreasonable in the application of building energy saving field, its application is restricted.Therefore, exploitation excellent thermal insulation performance and the good external-wall heat-insulation material of fire resistance are problems in the urgent need to address.
Summary of the invention
The present invention overcomes the defective that prior art exists, and a kind of inorganic building energy conservation wall thermal insulating heat-insulation composite material and preparation method thereof is provided, and this material has superior thermal and insulating performance and mechanical property, water proof fire retardant, and weather resistance is good, environmental protection.
For achieving the above object, the present invention adopts aerosil and pearlstone, glass fibre, clay compound, and preparation has the wall thermal insulating heat-insulation composite material of splendid heat-insulating property and mechanical property concurrently.
Inorganic building energy conservation wall thermal insulating heat-insulation composite material of the present invention is comprised of the raw material of following mass parts: aerosil 40-50, pearlstone 10-20, clay 5-10, glass fibre 5-10.
After above-mentioned materials and mineral binder bond mixed, repressed wall thermal insulating heat-insulation composite material.
Aerosil of the present invention adopts the method preparation of colloidal sol-gel take water glass as raw material, and the operation by optimizations such as soda acid two step method catalysis increases the porosity of material and specific surface area, and aperture size and thermal conductivity descend.
Described pearlstone is traditional inorganic heat preserving and heat insulation material that a kind of unit weight is light, thermal conductivity is lower, and price is lower, can reduce the cost of wall thermal insulating heat-insulation composite material.
Described clay, glass fibre can strengthen the intensity of wall thermal insulating heat-insulation composite material.
Described mineral binder bond is liquid soluble glass, and consumption is the 2%-5% of matrix material quality, the 2%-3.5% of preferred composite materials quality.
The present invention is than the beneficial effect of prior art
The present invention adopts sol-gel method to prepare the large aperture capacity silicon oxide aerogel take water glass as the silicon source, and pore volume reaches 2.5-3.0ml/g, and the thermal conductivity of matrix material reaches 0.030-0.040w/mk, and fire-protection rating reaches the A1 grade standard.Product of the present invention has superior thermal and insulating performance and mechanical property, water proof fire retardant, and weather resistance is good, environmental protection.
