Abstract

The invention discloses a gel LED (light-emitting diode) heat-dissipation paint which is prepared from the following raw materials in parts by weight: 4-6 parts of fine silicon dioxide aerogel, 2-3 parts of trichloroiminocyanuric acid, 360-400 parts of high-density polyethylene, 100-130 parts of sodium hydroxide, 400-420 parts of bisphenol A, 160-180 parts of epoxy chloropropane, 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 TritonX114, 1.8-2 parts of ammonia water, 10-20 parts of diethylenetriamine, 30-42 parts of nano carbon tube, 1-2 parts of N-hydroxymethyl acrylamide, 3-5 parts of aluminum dihydrogen phosphate, 1-2 parts of isopropyl myristate, 4-7 parts of dioctyl azelate and 7-10 parts of ceramic powder. The added fine silicon dioxide aerogel can improve the compatibility among the materials and enhance the surface strength and shock strength of the paint film.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating paint, in particular to a gel-led heat-dissipating paint 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 gel led heat dissipation coating and a preparation method thereof in order to remedy the defec...
