Abstract

The invention relates to a light-weight foamed fire-proof plate which is characterized by comprising the following components in weight percentage: 20-30% of kieselguhr, 20-30% of wollastonite, 8-12% of sawdust, 8-12% of expanded perlite, 15-30% of gelled material, 1-8% of hydrogen peroxide and 2-8% of ferrous sulfate. The microcellular structure of the light-weight foamed fire-proof plate can reduce the self weight of a product per se and increase the heat-insulating sound-insulating performance of the product. The invention not only effectively reduces the density of the material, but also effectively counteracts the damage of the material structure due to the effects of expansion on heating and contraction on cooling, and ensures the heat insulation and fire prevention efficiency of the material.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a lightweight foam fireproof board and a preparation method thereof. Background technique [0002] Asbestos and various products have excellent heat insulation and fireproof properties and low density, so they are widely used in fireproof linings of various buildings. However, asbestos and various products are highly carcinogenic, and the EU market has banned the use of various asbestos products. It is urgent to develop a fireproof material that has the same heat insulation and fireproof performance as asbestos, but also has a lighter density and can meet the relevant environmental protection regulations of the European Union. Contents of the invention [0003] The object of the present invention is to provide a lightweight foamed fireproof board and a preparation method thereof. The lightweight foamed fireproof board has good fireproof, heat insulation and e...
