Novel wall heat-preservation and heat-insulation material

Abstract

The invention relates to a class-A incombustible inorganic active wall heat-preservation and heat-insulation material, which comprises the following raw materials in parts by weight: 12-21 parts of micropore calcium silicate, 15-20 parts of closed pearl pine seeds, 5-11 parts of modified sepiolite, 6-12 parts of lightweight calcium powder, 1-3 parts of industrial synthetic fibers, 8-17 parts of modified lightweight gypsum powder, 5-8 parts of model-24-88 rubber powder, 3-11 parts of wood fibers, 1-3 parts of food film forming agents, 2-6 parts of hydroxymethyl cellulose, 0.2-1.1 parts of sodium formate and 1-2 parts of inorganic solidification agents. The class-A incombustible inorganic active wall heat-preservation and heat-insulation material has the characteristics of heat preservation, heat insulation, fire prevention, light weight, sound insulation, water resistance, cracking resistance, hollowing resistance, falling-off resistance, no cold and hot bridge generated and the like.

Description

[0001] technical field [0002] The invention relates to a grade A non-combustible inorganic active wall thermal insulation material. Background technique [0003] The current insulation materials are divided into three grades: B1 (flammable), B2 (combustible), and B3 (flammable). There are two categories. One is inorganic thermal insulation materials, which are non-combustible, but have poor thermal insulation effects. There are only 20 parts. The other is organic thermal insulation materials, occupying 80 shares of the market, which is characterized by good thermal insulation effect, but easy to burn. At present, domestic insulation materials generally have problems such as non-degradable, polluting the environment, burning in case of fire, easy cracking of the wall, water seepage, prominent problems of cold and heat bridges, and high comprehensive costs. Contents of the invention [0004] The object of the present invention is to provide a kind of A grade non-combustib...
