Abstract

The invention discloses a wear-resistant LED heat dispersion coating which is prepared from the following raw materials in parts by weight: 40-45 parts of acrylic resin, 7-10 parts of polyoxamide resin, 12-17 parts of methyl methacrylate, 10-14 parts of 4-cyclohexanedimethanol, 4-6 parts of fatty amine, 1-3 parts of allyl glycidyl ether, 5-8 parts of teflon powder, 1-2 parts of cross-linking agent TAIC, 2-3 parts of tributyl tin chloride, 15-18 parts of ethylene glycol, 4-6 parts of tungsten carbide powder, 3-5 parts of molybdenum diboride, 10-14 parts of silicon dioxide powder and 4-5 parts of film-forming aid. As teflon powder is added into the coating, the coating surface has good lubricating property, the wear resistance is improved, the surface tension is low and the coating has antifouling and dustproof effects; as tungsten carbide powder, molybdenum diboride and silicon dioxide powder are added into the coating, the wear resistance of the coating is improved, the heat dispersion effect is enhanced and the coating is ageing-resistant; due to the film-forming aid, the coating has good film-forming property and is easy to coat.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and particularly relates to a wear-resistant LED heat dissipation coating and a preparation method thereof. Background technique [0002] With the rapid expansion of the scope of use of LED lights, extending the service life of LED lights has become an urgent problem to be solved. With the increase of LED power, the heat dissipation problem has been paid more and more attention. At present, thermal conductive glue is used to solve the heat dissipation problem of LED lights, but the materials used have poor temperature resistance and aging resistance, low adhesion to the substrate, poor heat dissipation, and inconvenient construction. It is difficult to meet people's technical problems with LED lights. Heat dissipation requirements. Summary of the invention [0003] The purpose of the present invention is to provide a wear-resistant LED heat dissipation coating and a preparation method thereof. The co...
