Abstract

The invention discloses a thermoplastic powder coating. The thermoplastic powder coating is composed of following raw materials in parts by weight: 90-94 parts of polyethylene E309, 6-10 parts of thermoplastic polyurethane elastomer, 1-2 parts of perfluor-butyl potassium sulphonate, 0.2-0.4 part of tetramethyl thiuram disulfide, 0.4-1 part of N,N-diethyl aniline, 1-2 parts of ricinoleic acid, 1-2 parts of 1-ethoxyl-2-oleic imidazoline, 0.5-1 part of distearoyl isopropoxy aluminate, 2-4 parts of guar gum, 10-14 parts of epoxy soybean oil and 15-20 parts of modified fillers. The powder coating provided by the invention is particularly suitable for heat radiation coating of an LED (Light Emitting Diode) lamp and is convenient to use; the surface temperatures of a heat radiation cup, an aluminum substrate, a lamp cover and the like of the LED lamp so that the cooling effect is realized.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a thermoplastic 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 object of the present invention is to provide a thermoplastic powder coating. [0005] The present invention is achieved through the following technical solu...
