Abstract

The present invention discloses a brightening yellowing-resistant LED heat dissipation coating and a preparation method therefor. The coating consists of the following raw materials in parts by weight: 2-3 parts of calcium palmitate, 1-2 parts of zinc stearate, 0.4-1 parts of an oxidant 168, 360-400 parts of high-density polyethylene, 100-130 parts of sodium hydroxide, 400-420 parts of bisphenol A, 160-180 parts of epichlorhydrin, 10-12 parts of silicon nitride, 2-3 parts of acrylamide, 1-1.6 parts of ammonium chloride, 0.05-0.1 parts of N,N-methylenebisacrylamide, 3-4 parts of ammonium persulfate, 0.01-0.02 parts of Triton X114, 1.8-2 parts of ammonia, 10-20 parts of diethylenetriamine, 30-42 parts of carbon nano-tubes, 2-3 parts of dimethyl methylphosphonate, 2-3 parts of sodium fluoroborate, 1-2 parts of trimethylol propane, 0.3-1 parts of formamide, 3-4 parts of tetradecanol oleate and 18-20 parts of titanium dioxide. The calcium palmitate, the zinc stearate, the oxidant and the like are added to the coating, the oxidation resistance and yellowing resistance of a coating can be effectively improved; and in addition, the titanium dioxide is mixed, so that the whiteness of the coating is improved, and the decorative effect is high.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to a whitening and anti-yellowing LED heat dissipation coating and a preparation method thereof. Background technique [0002] Epoxy resin is one of the very important thermosetting polymer materials. It has the advantages of high bonding strength, good electrical insulation performance, low shrinkage rate, and good processing performance. It is widely used in various fields such as electronics, machinery, and construction; [0003] Carbon nanotubes have high thermal conductivity, so filling carbon nanotubes as a filling material into epoxy resin has a good application prospect as a heat dissipation material, but due to the nano-effect of carbon nanotubes, carbon nanotubes in Difficult to disperse in epoxy resin. Contents of the invention [0004] The purpose of the present invention is to provide a whitening anti-yellowing LED heat dissipation coating and a p...
