Abstract

The invention relates to a pearlite thermal-insulating fireproof board for the exterior wall of a building, which has the advantages that the fireproof performance is improved, the heat conducting coefficient is reduced and the flexibility and the strength are enhanced; and the requirements on the thermal-insulating performance of the exterior wall of the building are well satisfied, the energy is saved by 65 percent and the A-degree fireproof requirement is satisfied. The pearlite thermal-insulating fireproof board is made of the following raw materials by volume weight per cubic meter of products: 80-120kg of light modified expanded pearlite with volume weight per cubic meter being 65kg, 3-5kg of modified hollow beads with volume weight per cubic meter being 110kg, 2-6kg of 200-mesh sodium bentonite, 0.3-1.5kg of silica aerogel particles, 0.5-2kg of reinforced polypropylene (PP) fibers, 1-3kg of ceramic fibers, 0.3-1.5kg of asbestos wool, 20-30kg of inorganic modified water glass adhesive, 3-5kg of polyvinyl acetate adhesive, 0.5-3kg of modifier, 1-3kg of water repellent and 0.5-2kg of silicon aluminum powder, wherein the total percent of the volume weight per cubic meter of products is 100 percent. The pearlite thermal-insulating fireproof board is made through agitating, pressing, demolding, forming and drying processes. The coefficient of heat conductivity is as low as 0.045W / m.K.

Description

technical field [0001] The invention relates to a fireproof board, in particular to a perlite thermal insulation fireproof board for building exterior walls. Background technique [0002] At present, the perlite insulation board is made of expanded perlite, water repellent and binder as raw materials, and is made by high pressure pressing and thermal drying process.
