Description

technical field [0001] The invention relates to a nanometer thermal insulation material and a preparation method thereof, belonging to the technical field of thermal insulation materials. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.2. It has the functions of saving energy, reducing energy consumption, reducing the emission of harmful substances, improving people's living environment and prolonging the service life of buildings, and has gradually become an important part of building materials. Especially in today's environment where people's living standards are increasing and energy is increasingly scarce, the importance of thermal insulation materials is becoming more and more prominent. [0003] At present, the commonly used building insulation materials in my country can be divided into organic insulation materials and inorganic insulation materials. Among them, organic thermal insulation ...
