Heat insulation phase change coating and preparation method thereof

Abstract

The invention discloses a heat insulation phase change coating. The coating comprises the following components in parts by weight: 40-80 parts of double-component epoxy resin, 5-35 parts of heat dissipation filler, 5-30 parts of filler with high heat resistance and 5-25 parts of a phase change material. The heat insulation coating disclosed by the invention has the characteristics of high heat reflectivity, high heat radiation, low heat conduction, heat absorption, storage and release in a certain temperature range, multiple effects, good effects of reflecting illumination, realizing heat insulation and reducing temperature, safety, environment-friendly effect, strong adhesion and convenience in construction. The invention further discloses a preparation method of the coating.

Description

technical field

[0001] The invention relates to the technical field of thermal insulation coatings, in particular to a thermal insulation phase change coating and a preparation method thereof. Background technique

[0002] Heat insulation coating is a functional coating developed in the 1980s with heat insulation, reflection, energy saving and environmental protection. The most widely used are silicate composite coatings, which are mainly made of hollow thermal insulation aggregates with low thermal conductivity, such as asbestos, stone borers, expanded perlite, etc., combined with inorganic and organic binders and other additives. Widely used in petrochemical industry, grain storage and other industries. Relevant data show that the energy consumption required to lower the temperature by 1°C is four times that required to increase the temperature by 1°C. In the case of increasingly serious energy crisis, thermal insulation coatings are of great significance to energy savin...
