Heat-conducting composite plastic with insulating function

Abstract

The invention discloses heat-conducting composite plastic with an insulating function. The heat-conducting composite plastic is prepared from, by weight, 60-70 parts of ABS resin, 15-20 parts of BPS resin, 2-6 parts of alum, 14-20 parts of magnesium hypophosphite, 9-13 parts of melaMine cyanurate, 6-12 parts of silicon carbide, 3-7 parts of ammonium heptamolybdate, 2-9 parts of magnesium stearate, 12-25 parts of ethyl 3-ethoxypropionate, 1-3 parts of lactic acid, 23-29 parts of glass fibers, 12-23 parts of ceramic fibers, 23-27 parts of aluminum oxide, 1-3 parts of titanium dioxide, 3-7 parts of tetraethylthiuram disulfide, 4-10 parts of N-phenyl-alpha-naphthylamine, 3-7 parts of barium sulfate, 3-7 parts of phthalic acid ethyl caproic ester, 0.5-2 parts of antimonous oxide, 2-5 parts of decabromodiphenyl ether, 1-5 parts of simethicone and 1-2 parts of diethyldithiocarbamic acid. Unique molecular design is adopted, interaction force between thermoplastic plastic and filler is increased, a heat channel is formed through high-efficiency contact between the filler, and thermal conductivity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a heat-conducting composite plastic with insulation function. Background technique [0002] ABS resin has excellent mechanical properties and good electrical properties, and has the advantages of wear resistance, oil resistance, solvent resistance, self-lubrication, corrosion resistance and good processing performance, but its insulation, high temperature resistance and impact resistance are relatively low. not ideal. [0003] There are many studies and applications of thermally conductive plastics, which can be simply classified. According to the type of matrix material, it can be divided into thermoplastic thermally conductive resin and thermosetting thermally conductive resin; according to the type of filler particles, it can be divided into: metal filled type, metal oxide filled type , metal nitride filled type, inorganic non-metal filled type, fiber filled thermally condu...

Problems solved by technology

The fillers used for non-insulating thermally conductive plastics are usually metal powder, graphite, carbon black, carbon fiber, etc. This kind of filler is characterized by good thermal conductivity, which can easily make the material have high thermal conductivity, but at the same time it also makes The insulation performance of the material decreases or even becomes a conductive material
