Description

A kind of aluminum silicate composite heat-insulating coating for walls
Technical field
The present invention relates to a kind of thermal insulation coatings, particularly a kind of aluminum silicate composite heat-insulating coating for walls.
Background technology
Build work-ing life for reducing building energy consumption, prolonging, on building wall, use thermal insulation coatings usually.
Traditional wall heat insulation material exists water-absorbent big, and easily aging, volume change is big, causes the product later strength low, forms hollowing, cracking easily, influences the heat-insulating property of coating.
Granular polystyrene has good heat-insulating property, and existing composite heat-insulating coating is added with granular polystyrene usually.This no doubt helps to improve the heat-insulating property of thermal insulation coatings, but is added with the thermal insulation coatings of granular polystyrene, and inflammable, fire line is poor, and weathering resistance is low, bounce is big.In addition, granular polystyrene can produce a large amount of obnoxious flavoures when high temperature, during presence of fire, be unfavorable for the personnel escape.
Summary of the invention
The object of the present invention is to provide a kind of safe and reliable, the wall heat insulation material of good heat preservation performance.
The technical solution used in the present invention is:
A kind of aluminum silicate composite heat-insulating coating for walls, contain 2～3% redispersion type latex powder, aluminum silicate fiber 13～19%, Mierocrystalline cellulose 1～2%, wood fibre 0.25～0.35%, polypropylene fibre 0.4～0.7%, flyash 13～16%, silica powder 5.5～6.4%, closed pore heat-insulating granules 16～21%, surplus is a cement, and described per-cent is mass percent.
Dimension Mierocrystalline cellulose during Mierocrystalline cellulose is preferably, molecular weight is between 180,000～200,000.
The closed pore heat-insulating granules is preferably closed pore vitrified micro-bead heat preserving particle.
Aluminum silicate composite heat-insulating coating for walls of the present invention is the novel green inorganic materials, nontoxic, have that good sound-absorbing, high temperature resistant, water-fast, frost resistance energy, shrinking percentage are low, integral seamless, no cold bridge, heat bridge form; Steady quality is reliable, cracking resistance, anti-seismic performance is good, the wind suction prevention ability is strong, unit weight light, good heat insulating and have good workability, water-retentivity, strong adhesion, surface layer not hollowing, construction not sagging, sagging, reduce the construction consumption, combustionproperty is not an A level non-fire material; Temperature is rapid heat cycle in-40～800 ℃ of scopes, and thermal insulation layer does not ftracture, and does not come off, and does not burn acid-and base-resisting, wet goods advantage.It is big to have remedied the water-absorbent that exists in traditional wall heat insulation material, easily aging volumetric shrinkage is big, cause phenomenons such as the low reduction heat-insulating property that ftractures with hollowing of product later strength easily, it is inflammable simultaneously to have remedied the granular polystyrene organic materials again, defectives such as fire line difference high temperature produces obnoxious flavour and weather-proof low, and bounce-back property is big.The pure aluminium silicate thermal insulation coatings is that safety coefficient is the highest in the wall heat insulation material, and the optimal lagging material of over-all properties and workability can be smeared optimal economic thickness according to the different media temperature, and cost performance is better than equal performance materials greatly.
Aluminum silicate composite heat-insulating coating for walls of the present invention, moulding is firm, cohesive force is strong, convenient and quick construction is the reduction of erection time effectively, and be not subjected to the restriction of warmed body geometrical shape, be specially adapted to supply air system and special-shaped surfaces insulation under inner, external wall insulation, the central air-conditioning, can stop the traditional material slit and reveal and expended energy, constitute integral sealing.Product meets the GB/T20473-2006 operative norm, and reaches NFA and environmental requirement.
