Abstract

The invention discloses led nylon cooling coating. The led nylon cooling coating is composed of, by weight, 40-50 parts of nylon TR90, 5-8 parts of bone black, 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 bisacrylamide, 3-4 parts of ammonium persulfate, 0.01-0.02 part of TritonX114, 1.8-2 parts of ammonium hydroxide, 10-20 parts of diethylenetriamine, 30-42 parts of carbon nano-tubes, 2-3 parts of alkanolamide, 1-2 parts of guanidine sulfamate, 3-6 parts of acetyl tributyl citrate, 0.7-1 part of 8-hydroxyquinoline and 7-10 parts of polycarbonate diol. The nylon, polyethylene and epoxy resin are blended to form main coating materials, the surface strength of a coating can be effectively improved, and the impact resisting performance is improved.

Description

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