Abstract

The invention discloses a yellowing-resistant heat-dissipation paint which is prepared from the following raw materials in parts by weight: 94-100 parts of polypropylene, 1-2 parts of triglycol diisooctoate, 0.2-0.4 part of sodium molybdate, 5-7 parts of dibutyl maleate, 3-4 parts of oyster shell powder, 1-2 parts of dimethyl methyl phosphonate, 8-12 parts of calcined kaolin, 2-4 parts of polyethyleneglycol 1000, 2-3 parts of precipitated silica white, 1-2 parts of tetrabutylammonium bromide, 1-2 parts of propanediol phenyl ether and 8-10 parts of modified assistant. The heat-dissipation paint has the advantages of high adhesive force, favorable surface leveling property, no shrinkage void, high yellowing resistance and excellent comprehensive properties.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to an anti-yellowing and heat-dissipating coating. Background technique [0002] Thermally conductive and heat-dissipating coatings are widely used in fields that require heat dissipation, such as computers, notebook computers, LED lighting, communications, rectifiers, medical and industrial equipment, and are mainly coated on the surface of radiators. [0003] The heat dissipation coatings currently produced are generally used in the heat dissipation of components of electronic products such as CPUs and LED lamps. The requirements for the medium for painting are relatively high, and the adhesion to rough and loose surfaces is not strong, so the use effect is not ideal. The scope of application is small. Contents of the invention [0004] The object of the present invention is to provide an anti-yellowing heat-dissipating coating. [0005] The present invention is achieved through ...
