Problems solved by technology

At present, there are many thermal insulation materials in the market. The general inorganic thermal insulation materials are a single body, such as perlite and calcium silicate.
Traditional thermal insulation materials such as rock wool, glass wool, aluminum silicate fiber, etc., because the space of the thermal insulation body is not closed, the convection heat dissipation results in poor thermal insulation effect, and there are also short service life, easy aging, and brittleness. Defects such as cracking, high cost, failure to achieve energy conservation and environmental protection
[0003] The patent application with the publication number CN103043984A discloses an energy-saving thermal insulation material. The patent mainly uses bricks and tiles a

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to an energy-saving and environment-friendly thermal insulation material and a preparation method thereof. Background technique [0002] Insulation materials are a necessity in thermoelectric, fiber, petrochemical and other fields. At present, there are many insulation materials in the market. The general inorganic insulation materials are a single body, such as perlite and calcium silicate. Although they have good heat insulation and hardness, they have poor strength, and the insulation layer has many gaps and overlapping. Traditional thermal insulation materials such as rock wool, glass wool, aluminum silicate fiber, etc., because the space of the thermal insulation body is not closed, the convection heat dissipation results in poor thermal insulation effect, and there are also short service life, easy aging, and brittleness. Cracks, high cost, failure to achieve energy conservatio...
