Problems solved by technology

But it turns out that this kind of aspect has caused many "thermal bridges" due to many factors during production, which greatly reduces the thermal insulation effect
[0003] At present, most of the existing thermal insulation coatings have a single color, but the construction market requires rich colors, and the market needs more colorful thermal insulation coatings to meet the market demand for thermal insulation and beauty. At the same time, because white or light colors are used for a long time, Decreased heat reflection performance due to dirt, discoloration

Abstract

The invention discloses a heat reflecting paint for a metal plate and a preparation method of the heat reflecting paint. The heat reflecting paint is thin in painting layer, wide in application range and convenient to use. A colorized painting layer is obtained by the heat reflecting paint. Thus, compared with the common heat reflecting paint of a single color, according to the heat reflecting paint disclosed by the invention, the temperature of the surface of the metal plate is greatly decreased, so that the heat entering the metal plate is reduced; and the service life of the metal plate is prolonged.

Description

technical field [0001] The invention relates to a coating, in particular to a colored heat-reflecting coating and a preparation method and application of the coating. Background technique [0002] With the development of my country's industrialization and urbanization, my country has become the largest construction market in the world. Due to its "light weight", "high strength", "fast construction" and "good earthquake resistance", the steel structure system has entered the In the residential construction market, too, with the needs of public facilities and town construction, the demand for building curtain walls is on the rise. However, both aluminum and iron are good carriers of heat, but the national policy has higher and higher requirements for building energy conservation. The energy conservation of steel structures and aluminum curtain walls is especially critical. Energy-saving materials also meet the needs of market development.
