Abstract

The invention belongs to the technical field of polymer composite materials and discloses a polymer composite material for a laptop computer outer shell and a preparation method of the polymer composite material. The composite material is prepared from, by weight, 100 parts of polymer matrix resin, 0.1-50 parts of heat dissipation filler, 1-5 parts of a flame retardant, 0.5-1.5 parts of an antioxidant, 0.5-7 parts of a compatilizer, 0.1-0.5 part of an anti-dripping agent and 1-4 parts of a toughening agent. The polymer composite material is excellent in impact resistance, surface scratch resistance and flame retardation, requirements on plastic for the laptop computer outer shell can be met, and a high popularization and application value is achieved.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a polymer composite material used for a notebook computer casing and a preparation method thereof. Background technique [0002] Since the notebook computer has the characteristics of compact structure, strong mobility, and changeable use environment, the shell material is required to have high mechanical strength, scratch resistance, excellent high and low temperature impact resistance, good heat resistance, combustion resistance, light weight, Moreover, it has the characteristics of excellent formability, electroplating and low cost. [0003] At present, notebook computer shells are mostly made of engineering plastics, magnesium-aluminum alloy, carbon fiber and other materials; engineering plastic shells have good processability, and can manufacture thin-walled and complex-shaped products with excellent performance. The cost is low, and the biggest disadvantage is weight and heat...
