Abstract

The invention relates to a special skin-like dust-proof powdery coating for a radiator. The special skin-like dust-proof powdery coating comprises the following raw materials by weight: 240 to 360 parts of epoxy resin, 300 to 450 parts of carboxyl-terminated saturated polyester resin, 210 to 420 parts of a pigment and filler, 5 to 15 parts of skin-like modifier and 18 to 30 parts of other auxiliary agents. A film formed after coating of the radiator with the powdery coating touches smooth and fine as skin, can eliminate static electricity so as to prevent adsorption of dust, is improved in decorative and protective performance and has good practical value.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to powder coatings, in particular to a special skin-feeling dust-proof powder coating for radiators and its preparation method and application. Background technique [0002] Powder coating is a powder coating with a solid content of 100%, which is made of film-forming base material, pigment, filler, and auxiliary formula material. It is an energy-saving, environmentally friendly, VOC-free coating with excellent performance. The coating is durable and decorative. Powder coating radiators have many advantages, such as: 1. Excellent leveling, high gloss and high saturation; 2. Excellent adhesion; 3. Good delayed impact performance, the coating will last for several years , still has quite excellent flexibility; 4. It can meet the requirements of post-forming and is resistant to repeated bending; 5. Excellent resistance to oil stains and edible oils, and can be scrubbed repeatedly. How...
