Abstract

The present invention discloses an LED heat-dissipation fiber coating and a preparation method therefor. The LED heat-dissipation fiber coating consists of the following raw materials in parts by weight: 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 acrylic amide, 1-1.6 parts of ammonium chloride, 0.05-0.1 part of N,N-methylenebisacrylamide, 3-4 parts of ammonium persulfate, 0.01-0.02 part of TritonX114, 1.8-2 parts of aqueous ammonia, 10-20 parts of diethylenetriamine, 30-42 parts of carbon nano-tubes, 20-30 parts of precipitated barium sulfate, 2-3 parts of ammonium metaborate, 3-4 parts of ethyl cellulose, 5-7 parts of dimethyl methylphosphonate, 18-20 parts of calcined kaolin, 5-7 parts of polyoxypropylene glycol, and 0.7-1 part of lauryl diethanolamide. According to the invention, the added ethyl cellulose can effectively improve the compatibility of all the materials, thereby improving the dispersion effect.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to an LED heat dissipation fiber 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 kind of LED heat dissipation fiber coating and its preparation method in order to reme...
