Abstract

The invention discloses a polyethylene and polystyrene compound radiating coating which is prepared from the following raw materials in parts by weight: 10-17 parts of brominated polystyrene, 12-15 parts of a styrene-maleic anhydride copolymer, 6-10 parts of propynol, 90-100 parts of copolymer, 4-7 parts of graphene, 16-20 parts of nano silicon dioxide, 0.2-0.3 part of a saline coupling agent KH560, 700-800 parts of dimethylformamide, 4-5 parts of sodium nitride, 0.04-0.05 part of aluminum trichloride, 1.6-2 parts of a 2-3% sodium ascorbate solution, 1.8-2 parts of a 2-3% copper sulfate solution, 120-130 parts of high density polyethylene, 1-2 parts of diacetone alcohol, 1-2 parts of glycerol triglycerate, 0.6-1 part of diacetone-acryloamide, 0.3-1 part of sp80, 2-4 parts of calcium fluoride and 1-2 parts of magnesium fluoride. The coating disclosed by the invention is blended by polyethylene and polystyrene, so that the surface strength and toughness of the coating are effectively improved and the weather resistance and the antiaging property are improved.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating coatings, in particular to a polyethylene-polystyrene composite heat-dissipating coating and a preparation method thereof. Background technique [0002] With the rapid development of modern science and technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have greatly increased the total power density and calorific value of electronic devices per unit volume, thus making the cooling of electronic devices more difficult. increasingly prominent. However, the cooling capacity achieved by conventional cooling systems is greatly challenged, especially in the fields of energy, automobiles, air conditioning, agriculture, chemicals, heating, aerospace, microelectronics, information, etc. put forward higher requirements. The heat dissipation paint is a special paint that improves the heat dissipation efficiency of the surfa...
