Problems solved by technology

[0010] However, the thermal resistance of the thermal insulation board of the existing thermal insulation coating is relatively large, and the organic material used is flammable. The radiation rate decreases every year, and after about 5-7 years, the heat insulation effect will be lost
At the same time, due to the poor anti-fouling and waterproof effect of the existing thermal insulation coating, it is also a reason for the sharp decline in the thermal insulation effect.

Abstract

The invention relates to a waterproof thermal insulation coating composition, which comprises an aggregates, a substrate, an auxiliary filling and an assistant, and is characterized in that the aggregates are hollow glass microspheres, and the substrate is silicone acrylic emulsion; in the thermal insulation coating composition, 6-18 parts by mass of hollow glass microspheres and 21-27 parts by mass of silicone acrylic emulsion are provided. According to the invention, the silicon acrylic emulsion is selected, so that the thermal insulation coating has excellent thermal insulation property, and good waterproof and antifouling performance, and the waterproof and antifouling performance is more excellent for fluorine-containing silicone acrylic emulsion.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a thermal insulation coating composition and a preparation method thereof. Background technique [0002] After the 1970s, the world's climate became warmer, and the earth's energy sources were increasingly exhausted. In my country's energy consumption, building energy consumption accounts for 30-40% of human energy consumption. Improving the thermal insulation performance of buildings is an important way to save energy and improve the function of buildings. Applying thermal insulation coatings to the surface of buildings can effectively reduce the temperature on the surface and inside of buildings. In recent years, with the popularization of building energy conservation, thermal insulation coatings have attracted more and more attention due to their advantages of economy, convenience and good thermal insulation effect. Therefore, the research and development of new and compo...
