Problems solved by technology

[0003] After the 1980s, the world's climate became warmer and energy sources were increasingly exhausted. Under the dual pressures of environmental protection and energy sources, new requirements were brought to external wall insulation, which required both good thermal insulation performance and high flame retardancy. External wall insulation materials are mainly organic materials such as polystyrene and polyurethane. These materials have good insulation performance and construction performance, and the cost is relatively low. However, the fatal disadvantage of these materials is that they are easy to burn, and the combustion performance is B2

The heat insulation core board is made of 40-90wt% of superfine silicon dioxide power, 0-45wt% of filler, 0-20wt% of inorganic core materials, 1-18wt% of inorganic fibers, 0-3wt% of getter and 0-3wt% of vacuum stabilizer. The preparation method of the heat insulation core board includes steps of (1) burdening, (2) drying, (3) bag making by nonwoven fabrics, (4) core material filling, (5) bag material spreading, (4) compression forming and the like.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a wall insulation core board and a production method thereof. Background technique [0002] Insulation core board is a kind of insulation material, which is composed of filling core material and vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, so the thermal conductivity is greatly reduced, less than 0.008w / m. K, and does not contain any ODS materials, with the characteristics of environmental protection and high efficiency and energy saving. Compared with traditional heat insulation materials, the insulation core board has the advantages of thin layer, small volume, light weight and Class A combustion performance. [0003] After the 1980s, the world's climate became warmer and energy sources were increasingly exhausted. Under the dual pressures of environmental protection and energy sources, new r...
