Abstract

The invention provides a polycarbonate / ABS composition, a preparation method and an automobile pillar guard plate. The composition comprises the following components in parts by weight: 50-80 parts of polycarbonate, 10-40 parts of ABS, and 1-10 parts of compatibilizer; 1-10 parts of toughening agent, 0.1-1 part of antioxidant, 0.1-1 part of light stabilizer, 0.1-1 part of ultraviolet absorber, 0.1-1 part of heat stabilizer, 0.1 part of lubricant ‑1 serving. The polycarbonate / ABS composition provided by the present invention has the characteristics of high flow and high toughness, and is easy to fill and form large-sized molds. Notched impact performance, the notched impact strength at room temperature is increased by more than 2 times, and the notched impact strength at low temperature is increased by more than 4.5 times. At the same time, it has weather resistance and long-term aging resistance. It has good application prospects in automotive pillar guards and other fields.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polycarbonate / ABS composition, a preparation method and an automobile pillar guard. Background technique [0002] The composition of polycarbonate and styrene butadiene acrylonitrile copolymer combines the excellent characteristics of the two materials, and the division is impact resistance, low temperature resistance, chemical resistance, easy processing and molding of ABS materials, The advantages of dimensional stability and the properties of PC such as heat resistance, impact resistance, ultraviolet resistance (UV) and good mechanical properties can be widely used in automotive interior and exterior trims. [0003] With the development of the automobile industry, people have higher and higher requirements for the safety of automobile interiors. The A-pillar of an automobile refers to the pillar between the windshield and the front door, which plays the role of buffer protecti...
