Abstract

The invention provides an efficient energy-saving insulation material. The efficient energy-saving insulation material is prepared from, by weight, 400-500 parts of water, 200-250parts ofperlite powder, 10-20parts ofsodium silicate, 30-40parts of aluminum silicate wool, 10-30parts ofsepiolite powder, 0.1-0.5 part ofwhite clay powder, 0.1-0.3part of bentonite, 0.3-0.7part of cured rubber powder I, 0.1-0.5part of cured rubber powder II,0.3-0.7part ofcellulose,2-5parts offoaming agent, 1-10 parts offlame retardant, 0.3-0.7part ofpolyacrylamide, 0.1-0.5part ofpolyvinyl alcohol and 0.1-0.5part of aluminum phosphate. The efficient energy-saving insulation material has a good insulation effectand has a very stronghigh temperature resistance performance and flame retardant performance.

Description

technical field [0001] The invention provides a high-efficiency energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] The current thermal insulation materials are mainly solid, flocculent and foamy. There are many problems in this thermal insulation material: poor fire resistance, flammability, polluting the environment, and poor thermal insulation effect for high temperature. During the construction, multiple processes such as pasting, hanging nets, and fixing are required, which is very cumbersome. At the same time, the limitation of the shape of traditional thermal insulation materials makes it inconvenient to construct in special places such as narrow spaces. Due to solid or flocculent and construction techniques, there are always gaps in the well-made insulation layer, which affects the insulation effect. Such insulation materials cannot be recycled and must be renewed after three years, which wastes resources and ene...
