Abstract

The invention relates to a high multi-axis impact polycarbonate composition and a preparation method of the high multi-axis impact polycarbonate composition. The composition comprises the following components in parts by weight: 50-70 parts of polycarbonate resin PC, 25-50 parts of polybutadiene-acrylonitrile-styrene copolymer resin ABS, 2-10 parts of toughening agent, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant. The preparation method of the high multi-axis impact polycarbonate composition comprises the following steps of: dividing raw material into parts A and B, wherein the part A comprises the PC, the antioxidant and the lubricant while the part B comprises the ABS and the toughening agent; and respectively premixing the parts A and B in a high-speed mixer, subsequently adding the premixed materials into a double-screw extruder, feeding the part A from a primary feeding opening and feeding the part B from a secondary feeding opening, fusing and extruding at 200-280 DEG C with the rotation speed of the screw extruder at 200-600rpm and the pressure at 2-3MPa, then fusing, extruding and pelleting to obtain the product. Compared with the prior art, through the special toughening agent, PC and processing technologies, the multi-axis impact performance of the polycarbonate composition provided by the invention is improved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polycarbonate composition with high multiaxial impact and a preparation method thereof. Background technique [0002] Due to the demand for environmental protection and energy saving, the trend of automobile development is lightweight and high safety performance. The lightweight of the car is to reduce the curb weight of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce the consumption of dyes, and reduce the exhaust pollution. In order to meet the demand for lightweight vehicles, both metal parts and plastic parts are reducing weight. Especially for plastics, when the thickness is reduced, it needs to meet the requirements of high safety performance, and the requirements for the strength of materials are becoming more and more stringent. Polycarbonate resin is widely used in...
