However, these insulation materials have many defects.
1. EPS and XPS thermal insulation boards: unable to achieve Class A fire protection, poor structure point adhesion, easy to generate thermal bridges, easy to age, base wall needs to be leveled, not suitable for modeling parts, low strength, waste of cutting boards, not suitable for Cross-operation, belonging to organic chemical materials with pollution
2. Polyurethane foam: unable to achieve Class A fire protection, easy to age, sometimes the outside of the insulation layer needs to be leveled, not suitable for modeling parts, low strength, not suitable for cross-operation, and is polluted by organic chemical materials; 3. Glass wool, rock wool Board: Poor structural point bonding integrity, easy to generate thermal bridges, sometimes the base wall needs to be leveled, not suitable for modeling parts, low strength, waste of cutting boards, construction operations stimulate the human body, easy to absorb water and moisture; 4. Phenolic board: structure Poor integrity of point adhesion, easy to generate thermal bridges, easy to aging, easy to pulverize, the base wall needs to be leveled, not suitable for modeling parts, low strength, waste of cutting boards, organic chemical materials, polluting and toxic

Abstract

The invention discloses inorganic heat-preserving slurry, which consists of following raw materials in percentage by weight: 25-45 percent of early strength cement, 35-55 percent of closed pore perlite, 10-20 percent of inorganic fiber, 2-10 percent of rare earth and 1-5 percent of rubber powder, wherein the inorganic fiber is asbestos or glass fiber or a mixture thereof; and the particle diameter of the closed pore perlite is 1.5-2.0 millimeters. The inorganic heat-preserving slurry does not burn fundamentally, is free from fire control potential safety hazard, has a structure in a fully-bonded form, has high integrity, and is free from splicing gaps and heat bridges; an inorganic material is not aged or deformed, has the same service life as a building main body, is not required to be replaced, and is low in maintaining cost; both sides of a substrate wall body are not required to be optimized with a mortar leveling structure, so that the overall thickness of an outer wall is reduced, and the construction ratio is increased; a construction process is simple and convenient, and is suitable for special parts and various shapes; and the inorganic heat-preserving slurry has high strength after being molded, is suitable for field molding of a stressed and impacted part, and is free from cutting waste.
