Abstract

The invention discloses a thermoplastic resin composite material notebook computer C shell. The C shell is prepared from, by weight, 40 to 50 parts of carbonyl-terminated hyperbranched polycarbonate, 8 to 12 parts of waste aromatic oxadiazole fibers, 30 to 40 parts of PBT resin, 3 to 5 parts of a coupling agent, 3 to 6 parts of dimethyl carbonate oxadiazole benzotriazolyl butyl phenol sulfonate, 5 to 8 parts of graphene fibers, 4 to 6 parts of glass fibers, 1 to 2 parts of an antioxidant, 3 to 5 parts of a compatilizer and 1 to 3 parts of a lubricant. The invention further discloses a manufacturing process of the thermoplastic resin composite material notebook computer C shell. The thermoplastic resin composite material notebook computer C shell disclosed by the invention is excellent in mechanical property, good in heat resistance and heat-conducting property, good in low-temperature impact resistance and sufficient in performance stability.

Description

technical field [0001] The invention relates to the technical field of notebook computer shell processing, in particular to a thermoplastic resin composite material notebook computer C shell and a manufacturing process thereof. Background technique [0002] Notebook computer belongs to a kind of small computer, has advantages such as volume is small, is easy to carry, has obtained extensive application at present. With the continuous improvement of the technological level, people's requirements for the quality and appearance of notebook computers are also continuously improved.
