Description

technical field [0001] The invention relates to the field of heat preservation, in particular to an energy-saving and environment-friendly heat preservation material and a preparation method thereof. Background technique [0002] Building thermal insulation is an important aspect of saving energy, improving the living environment and using functions. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air conditioning energy consumption, so building energy conservation is of great significance. Insulation materials are developing rapidly. Using good insulation technology and materials in industry and construction can often achieve twice the result with half the effort and effectively save energy. With the progress of society and the improvement of people's living standards, people's requirements for building materials are getting higher and higher, especially the insulation materials in bui...
