Thermal insulation coating and preparation method thereof

Abstract

The invention relates to the technical field, and discloses a thermal insulation coating and a preparation method thereof. The thermal insulation coating is mainly composed of the following raw materials in parts by weight: 50-60 parts of deionized water, 10-15 parts of perlite, 3-5 parts of sepiolite, 5-10 parts of porous konilite, 3-5 parts of hollow glass beads, 5-8 parts of aluminum silicate, 5-8 parts of acrylic emulsion, 5-10 parts of light calcium carbonate, 2-3 parts of wood fibers, 1-2 parts of an adhesive and 1-2 parts of an antifoaming agent. The thermal insulation coating is small in heat conductivity coefficient and has excellent thermal insulation effects, and compared with general thermal insulation coatings, the thermal insulation coating disclosed by the invention has high tensile strength and overall adhesion and cohesiveness.

Description

Technical field [0001] The invention relates to the technical field, in particular to a thermal insulation coating and a preparation method thereof. Background technique [0002] As my country's urbanization process is advancing step by step, a large number of new buildings are being constructed every year. In the current environment of energy saving and emission reduction, building energy saving has become the focus of social attention. The main method of building energy saving is to reduce the transmission of indoor and outdoor temperature, that is, to heat the inner and outer protective structure of the building. A large number of experiments are also the same. Insulation technology can obviously protect the wall and save energy. [0003] In the traditional external thermal insulation system, the finish coating only has decorative and general waterproof functions, and does not have thermal insulation functions, which has certain limitations for the protection of the entire syst...

AI Technical Summary

Problems solved by technology

[0003] In the traditional external thermal insulation system, the finishing coating only has the function of decoration and general waterproofing, and does not have the function of thermal insulation, which has certain limitations for the protection of the entire system.

However, some existing thermal insulation coatings generally have problems such as thermal insulation and thermal insulation performance are not good, and the service life of the thermal insulation system is short.
