Building thermal insulation material

Abstract

The invention discloses a building thermal insulation material. The material is prepared from, by weight, 15-35 parts of expanded vermiculite, 20-30 parts of dolomite powder, 10-20 parts of calcium carbonate powder, 2-5 parts of polyether polyol, 5-10 parts of silicon carbide fiber, 5-10 parts of glass fiber, 6-10 parts of polypropylene glycol, 5-7 parts of chitosan, 2-5 parts of dispersible latexpowder and 10-15 parts of inorganic gel. The expanded vermiculite, the dolomite powder, the calcium carbonate powder, polyether polyol, silicon carbide fiber, the glass fiber, polypropylene glycol, chitosan, the dispersible latex powder and the inorganic gel are used as raw materials, the compositions are reasonable, interaction and mutual influence of the various components are achieved, and theprepared thermal insulation material is resistant to acid and alkali, has high cohesiveness and does not easily fall off.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building insulation material. Background technique [0002] Building materials, the materials used in buildings are collectively referred to as building materials. New building materials include a wide range, including thermal insulation materials, heat insulation materials, high-strength materials, and materials that can breathe, all of which are new materials. Building materials is a collective term for materials used in civil engineering and construction. In building materials, thermal insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.2. With the implementation and development of building energy conservation, thermal insulation materials are getting more and more attention. There are many existing thermal insulation material formulations, but most of them have acid and alkali resistance, Poor bonding performance...

In building materials, thermal insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.2. With the implementation and development of building energy conservation, thermal insulation materials are getting more and more attention. There are many existing thermal insulation material formulations, but most of them have acid and alkali resistance, Poor bonding performance, easy to fall off and other hidden dangers
