Abstract

The invention discloses multi-fiber powder coating consisting of the following raw materials in parts by weight: 87-90 parts of polypropylene, 1-2 parts of ferric trichloride, 80-86 parts of polyvinyl chloride, 1-2 pats of calcium aluminate, 10-15 parts of carbon fiber, 5-7 parts of polytetrafluoroethylene fiber, 0.4-1 part of isooctyl di-n-octyl tin dimercaptoacetate, 4-6 parts of semi-reinforcing carbon black, 6-8 parts of triglycol diisooctoate, 2-3 parts of diacetone alcohol, 1-2 parts of chitosan and 10-14 parts of modifying filler. The powder coating disclosed by the invention is specifically suitable for cooling coating of light emitting diode (LED) lamps, is strong in adhesion force, good in surface levelling property, high in tensile strength and elongation at break, and has excellent comprehensive performance.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a multi-fiber powder 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 purpose of the present invention is to provide a multi-fiber powder coating. [0005] The present invention is achieved through the following technical solutio...
