Preparation method of inorganic heat-preserving material

Abstract

The invention relates to a method for preparing an inorganic heat-preserving material with high flame resistance from desulfurated gypsum, and belongs to the technical fields of comprehensive utilization of solid wastes and building materials. The method comprises the following steps of: modifying inorganic lightweight aggregate vitrified microbubbles by using a water repellent; adding the desulfurated gypsum, sierozem powder, siliceous dust, a water-retaining agent and a retarder in a ratio; adding a certain amount of organic emulsion and water; and stirring completely and uniformly to obtain a pasty heat-preserving material applied to construction of a heat-preserving layer. By the method, the solid wastes are utilized; and the prepared inorganic heat-preserving material has fire resistance, flame resistance, low thermal conductivity coefficient and good heat-preserving effect.

Among the current thermal insulation materials, organic thermal insulation materials are the main ones, because organic thermal insulation materials have excellent characteristics such as good thermal insulation effect, light weight, high specific strength, and convenient construction. However, more and more fire accidents indicate that organic thermal insulation materials have obvious defects. fire hazard

Moreover, it will burn in a fire to produce a large amount of toxic gas, which will cause serious harm to the human body and even death.
