Abstract

The invention discloses a decorative LED heat dissipation coating and a preparation method therefor. The decorative LED heat dissipation coating comprises the following raw materials in parts by weight: 10-13 parts of villi powder, 2.4-3 parts of coconut acid diethanolamide, 360-400 parts of high-density polyethylene, 100-130 parts of sodium hydroxide, 400-420 parts of bisphenol A, 160-180 parts of epichlorohydrin, 10-12 parts of silicon nitride, 2-3 parts of acrylamide, 1-1.6 parts of ammonium chloride, 0.05-0.1 part of N, N-methylene-bis-acrylamide, 3-4 parts of ammonium persulfate, 0.01-0.02 part of Triton X 114, 1.8-2 parts of ammonia water, 10-20 parts of diethylene triamine, 30-42 parts of carbon nanotubes, 2-3 parts of dodecyl mercaptan, 3-4 parts of alkenyl succinic acid esters, 1-2 parts of sodium fluoride, 4-5 parts of polyethyleneimine, 3-4 parts of calcium stearate and 17-21 parts of titanium dioxide. The villi powder is added into the decorative LED heat dissipation coating disclosed by the invention, so that the texture of a coating is improved, and the coating has a scrub feeling, and the decorative property is improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to a decorative 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 object of the present invention is to provide a decorative LED heat dissipation coating and a preparation method thereof in order ...
