Insulating powder coating and preparation method thereof

Abstract

The invention relates to an insulating powder coating, comprising the following components in parts by weight: 35-45 parts of hydroxy acrylic resin, 30-35 parts of carboxyl-terminated polyester resin, 2-6 parts of tetramethoxy methyl glycoluril, 10-40 parts of calcium carbonate, and 0.1-1 part of potassium manganate. The powder coating is decomposed at the curing temperature of 190 DEG C to generate oxygen, so that micropores exist on a film; the micropores have a good respiratory action; and the micropores absorb vapor when the humidity is large, so that the surface is kept dry and the coating plays a moisture-proof role.

Description

[0001] technical field

[0002] The invention relates to a heat-insulating powder coating, and also relates to a preparation method of the heat-insulating powder coating. Background technique

[0003] With the rapid development of my country's construction industry and the increasingly prominent energy crisis, the energy saving and consumption reduction of buildings is becoming more and more important. The proportion of building energy consumption in the entire energy consumption is generally 30-40%, and the vast majority of it is energy consumption for heating and cooling. At present, more than 90% of buildings in my country are high-energy buildings. Therefore, research and development of building insulation Coatings have significant economic, environmental and social benefits. The use of coatings with heat insulation function inside and outside the building can not only realize the original decoration, protection and anti-corrosion functions of the coating, but also make ...
