Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a safe and environment-friendly thermal insulation material and a preparation method. Background technique [0002] Insulation material is a material or composite material that slows down the rate of heat flow generated by conduction, convection, and radiation. Insulation resists the flow of heat into and out of a building due to the material's high thermal resistance. Insulation materials are widely used in various cold and hot media pipes and containers in central air-conditioning, construction, chemical, pharmaceutical, textile, metallurgy, shipbuilding, vehicles, electrical and other industries and departments to reduce the effect of cold and heat loss. Insulation materials usually have the characteristics of light weight, looseness, porosity, and low thermal conductivity. In building insulation, people usually regard materials with a thermal conductivity <0.1...
