Problems solved by technology

In addition, the electrical casing made of the existing ABS raw materials generally needs to be sprayed with high-gloss paint to make it have the characteristics of high gloss, but the high-gloss paint is not environmentally friendly, and there will be paint stripping, and it needs to be sprayed separately when preparing the electrical casing The process of high-gloss paint has complicated process steps, low production efficiency and high cost

Abstract

The invention relates to a highlight halogen-free flame-retardant PC / ABS composite material for an electric appliance shell. The material is mainly composed of, by weight, 50-80 parts of PC resin, 10-30 parts of ABS resin, 5-20 parts of halogen-free flame retardant, 1-5 parts of halogen-free flame retardant synergist, 3-8 parts of compatilizer, 0.3-0.8 part of polytetrafluoroethylene powder, 0.1-0.5 part of antioxygen and 0.1-0.5 part of light stabilizer. A preparation method of the material includes the steps of raw material mixing, squeezing and granulating. The material is easy to prepare, good in appearance, safe to use and high in brightness, heat resistance and mobility, can be widely applied to the electric appliance shell of the home appliance field and has wide application prospects on the aspects of high-end television set shells and cell phone components.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a composite material of high-performance high-gloss halogen-free flame-retardant polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS) used for electrical casings. Background technique [0002] Polycarbonate / acrylonitrile-butadiene-styrene copolymer composite material (hereinafter referred to as PC / ABS composite material) is a high-performance thermoplastic engineering plastic with good comprehensive properties that has developed rapidly in recent decades. It combines the excellent characteristics of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS) into one, such as excellent impact resistance, heat resistance and rigidity, and also has High gloss, excellent processing fluidity and dimensional stability, so it is widely used in the fields of communication electronic instruments, office equipment, household appliances and auto parts. However, s...
