Abstract

The invention discloses a special material for a notebook computer casing. The material comprises, by weight, 20-30 parts of polyethylene terephthalate, 15-25 parts of polycarbonate, 23-32 parts of polypropylene, 17-28 parts of polyamide resin, 2-4 parts of glass fibers, 3-6 parts of basalt fibers, 5-9 parts of modified talc powder, 1-3 parts of flame retardant, 2-4 parts of toughening agent, 1-3parts of lubricant and 1-2 parts of dispersing agent. The special material for the notebook computer casing has better comprehensive performance, lower density and high specific strength and exhibitsexcellent impact resistance under the premise of high strength and high rigidity at the same time.

Description

[0001] technical field [0002] The invention belongs to the technical field of computer shells, and in particular relates to a special material for notebook computer shells and a preparation method thereof. Background technique [0003] With the rapid development of the notebook computer industry, the notebook computer casing is also developing in the direction of high strength, high rigidity and light weight. At present, most of the plastic shell notebook computers on the market are made of PC / ABS engineering plastic alloy. This material not only has the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin. However, with the development of notebook computers, the comprehensive mechanical properties of PC / ABS alloys are not ideal due to factors such as protecting fragile electronic components and strengthening the strength of the overall structure, resulting in unsatis...
