A kind of body of wall thermal insulation fire-proof insulation material
Technical field
The present invention relates to building material field, be specifically related to a kind of body of wall thermal insulation fire-proof insulation material and preparation method.
Background technology
State's heat insulating material for external industry has had very long history, building energy conservation accounts for the overwhelming majority with insulation material, as the U.S. has accounted for the most probably left and right of all insulation materials from building thermal insulation material since 1987, the Western European countries such as Sweden and Finland most probably above asbestos product for building energy conservation. China is relatively less for the heat-insulation material of building energy conservation. At present, country is putting into effect relevant policies, widelys popularize building energy conservation, and this is by the application that greatly promotes heat-insulation material in architectural engineering. Related data shows, China every year for the expense of building heat preservation at 300 ~ 50,000,000,000 yuan, but insulation material great majority that use or kind is single, the product of function singleness directly cause a large amount of energy consumptions.
Country also requires more and more stricter to the security of building insulation material used, ensure the requirement of health and the requirement of personal safety, material must be nontoxic, harmless, pollution-free and must prevent fires, in organic material, almost completely without fire resistance property, some even meets fire can discharge toxic gas.
Inorganic heat insulation material composition is not aging, and having not can thermal expansion, cold contraction, cracking resistance, the anti-good self-characteristic such as come off. Comparing with general insulation material, have own special performance superiority, be irreplaceable performance characteristics in construction material, and cost is lower, can save lot of materials, cost of labor. But the commercially available large problem of the inorganic heat insulation material ubiquity coefficient of heat conduction, causes a large amount of energy consumptions at present.
Summary of the invention
First object of the present invention is to provide a kind of body of wall thermal insulation fire-proof insulation material, comprise the raw material of following weight portion: 25 ~ 40 parts of expanded perlites, 15 ~ 20 parts of light ceramics, 5 ~ 10 parts of phosphate, 5 ~ 10 parts, magnesium chloride, 5 ~ 10 parts of magnesium hydroxides, 5 ~ 20 parts of fibers, 2 ~ 8 parts of silicate, 1 ~ 3 part, refractory ceramics glue, 1 ~ 5 part, alum, 10 ~ 25 parts, flyash.
Above-mentioned expanded perlite is closed-cell expanded perlite.
Above-mentioned phosphate is sodium dihydrogen phosphate, magnesium dihydrogen phosphate or aluminium dihydrogen phosphate.
Above-mentioned silicate is sodium metasilicate or calcium silicates.
Above-mentioned fiber is wood fibre and/or alumina silicate fibre.
Second object of the present invention is to provide a kind of preparation method of body of wall thermal insulation fire-proof insulation material: expanded perlite, light ceramic, phosphate, magnesium chloride, magnesium hydroxide, fiber, silicate, refractory ceramics glue, alum and flyash are mixed in proportion; Dry, expanded, be ground into 200 object fine powders, put into mixer and add water and stir and mix; To absorb water paper washer at die surface, and gained mixture is poured extrusion forming in mould into; It is 85 ~ 95 DEG C that oven temperature is set, and the raw material module obtaining is sent in baking oven to dry to 6 ~ 8 one-tenths be dried after extrusion forming; Take out shaped heat insulation material cooling completely after, effects on surface carries out press polish processing; Press polish layer is smeared one deck curing agent on its press polish layer surface after being dried completely; After curing agent layer is dried completely, obtain body of wall thermal insulation fire-proof insulation material.
Above-mentionedly prepare the raw mixture of body of wall thermal insulation fire-proof insulation material and the mass ratio of water is raw mixture: water=1:1.2 ~ 1.8.
Above-mentioned press polish step is to smear at heat insulation material surface the lime mortar layer that a layer thickness is 15 ~ 30mm.
Above-mentioned lime mortar layer is that mass ratio is lime: the mixed slurry of sand: water=1:1:3.
Above-mentioned curing schedule is to smear one deck organic silicon water-proofing curing agent at cooling forming heat insulation material surface.
The advantages such as product waterproof of the present invention, fire prevention, corrosion-resistant, intensity is high, long service life.
