Problems solved by technology

With the improvement of people's living standards, the development of urban construction, and the continuous expansion of the scale of industrial and mining enterprises, the surface of many metal plates needs heat insulation, heat preservation, and fire prevention, such as the sandwich panels of polyurethane foam layers used in the walls of steel structure workshops, Heating pipes, etc., because these materials use rock wool as the sandwich layer, which is not environmentally friendly and very flammable, and is a dangerous building material

Abstract

The invention belongs to the technical field of coatings and specifically relates to a foaming powder coating which is prepared from the following raw materials in parts by weight: 720-770 parts of polyester resin, 60-80 parts of curing agent, 180-220 parts of washed kaolin, 3-7 parts of foaming agent, 1-3 parts of pigment, 1-3 parts of wax powder and 0.05-0.2 part of cellulose acetate butyrate. The coating provided by the invention is suitable for different metal building materials, and has the advantages of strong adhesive force, high coating hardness and perfect thermal insulation effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a foaming powder coating. Background technique [0002] With the advancement of technology and social development, people pay more and more attention to environmental protection. Powder coatings with "economy, environmental protection, high efficiency and energy saving" have been developed rapidly, and various functional powder coatings have come out one after another. With the improvement of people's living standards, the development of urban construction, and the continuous expansion of the scale of industrial and mining enterprises, the surface of many metal plates needs heat insulation, heat preservation, and fire prevention, such as the sandwich panels of polyurethane foam layers used in the walls of steel structure workshops, Heating pipes, etc., because these materials use rock wool as the sandwich layer, it is not environmentally friendly and very flammable, and is a dan...
