Heat conduction waterproof composite plastics

Abstract

The invention discloses heat conduction waterproof composite plastics. The heat conduction waterproof composite plastics is prepared from, by weight, 60-70 parts of high-density polyethylene, 15-20 parts of nitro-cotton resin, 2-6 parts of carbon dust, 14-20 parts of magnesium phosphate, 9-13 parts of melamine cyanurate acid, 6-12 parts of silicon carbide, 3-7 parts of ammonium heptamolybdate, 2-9 parts of magnesium stearate, 12-25 parts of 3-ethoxypropionic acid ester, 1-3 parts of lactic acid, 23-29 parts of kaolin, 12-23 parts of cellose, 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 mono(2-ethylhexyl) phthalate, 0.5-2 parts of antimonous oxide, 2-5 parts of decabromodiphenyl ether, 1-5 parts of dimethicone and 1-2 parts of diethyldithiocarbamic acid. The obtained plastics has the good heat conduction and waterproof functions, the mechanical strength of the plastics is not affected, meanwhile, the compatibility of the plastics and resin is good, and the composite plastics will not be migrated or separated or extracted in plastic products.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a heat-conducting and waterproof composite plastic. Background technique [0002] The integration of electronic circuits is getting higher and higher, and the accumulation of heat is also increasing. The accumulation of heat causes the temperature of the device to rise and the working stability to decrease. Therefore, its material is required to have high thermal conductivity so that heat can be conducted out quickly. However, most of the heat-conducting plastics used in electronic products on the market are made of non-high-temperature-resistant materials, resulting in low thermal conductivity of the worthwhile products. [0003] At the same time, in order to adapt to different working environments and usage needs, the performance of plastics will be improved, and plastics with only a single function are increasingly at a disadvantage in the increasingly competitive market. ...

Problems solved by technology

The quality of the modified plastics on the market is not stable, and the waterproof performance is not good, and some electronic products used outdoors, such as outdoor units of air conditioners, outdoor electrical boxes, etc., are still prone to leakage if they are splashed or drenched in rain. As a hazard, so the plastic should also have good water resistance
