Abstract

The invention belongs to the technical field of composite materials and particularly relates to a PC / ABS composite material. Based on 100% of the total mass of the PC / ABS composite material, the PC / ABS composite material comprises the following raw material ingredients in percentage by mass: 20%-80% of polycarbonate, 10%-60% of acrylonitrile-butadiene-styrene graft copolymer, 2%-11% of compatibilizer, 2%-10% of toughener, 1%-10% of compounded efficient flame retardant, 0.3%-1% of antioxidant and 0.3%-2% of light absorbent. According to the PC / ABS composite material disclosed by the invention,through action of all the ingredients, the ultraviolet resistance of the PC / ABS composite material is improved, the defect of rapid yellowing of the PC / ABS composite material is overcome, and meanwhile, the PC / ABS composite material can have the advantages that the mechanical properties are good, the divergence is low, interior trimming flame retardance requirements of new-edition transport business vehicle national standards (JT / T 1095-2016) are met, and the like.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a PC / ABS composite material with high performance, ultraviolet resistance, environmental protection and flame retardancy and a preparation method thereof. Background technique [0002] Polycarbonate (PC) has many advantages such as high heat resistance, high transparency, excellent mechanical properties and good flame retardancy, and is widely used in automotive materials and other industries, but it also has obvious disadvantages, such as: Notch sensitivity is high, stress cracking is more likely to occur, and the viscosity is high, which is not conducive to processing. In order to make better use of its advantages and effectively improve its shortcomings, it is found that it is relatively easy to prepare alloy materials by blending with other resins. For example, blending PC and acrylonitrile-butadiene-styrene graft copolymer (ABS) to prepare PC / ABS all...
