▎ 摘 要
NOVELTY - A polyethylene-based urea-containing heat-dissipating coating comprises beta -naphthol, lanolin acetate, benzyltriethylammonium bromide, styrene-maleic anhydride copolymer, propargyl alcohol, tetrahydrofuran, graphene, nano-silica, silane coupling agent KH-560 (RTM: gamma -Glycidoxypropyltrimethoxysilane), dimethylformamide, sodium azide, aluminum trichloride, sodium ascorbate solution, copper sulfate solution, high-density polyethylene, p-tert butylphenol, stannous octoate, hexamethylphosphoramide, aluminum dihydrogen phosphate and urea. USE - Polyethylene-based urea-containing heat-dissipating coating (claimed). ADVANTAGE - The heat-dissipating coating has excellent film-forming property, peel strength and acid and alkali resistance.
