Abstract

The invention discloses a highlight spraying-free polycarbonate PC composition. The highlight spraying-free polycarbonate PC composition comprises the following components: polycarbonate resin, ABS resin, white mineral oil, a silane coupling agent, modified polysiloxane, a flame retardant, a flexibilizer, polymethyl methacrylate, an antioxidant and a lubricant. The invention belongs to the technical field of high polymer materials, and particularly relates to a highlight spraying-free polycarbonate PC composition which is high in processability, free of surface fogging, resistant to scraping and good in stability.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and specifically refers to a high-gloss spray-free polycarbonate PC composition. Background technique [0002] Due to the high pollution, high cost and great harm to the human body caused by the spraying of plastic parts, high-gloss spray-free materials have become the focus of the market. In particular, high-gloss spray-free materials based on polycarbonate are widely used for their excellent physical properties and strong impact resistance. However, due to the poor processability of polycarbonate materials, an alloy material of polycarbonate and styrene-butadiene-acrylonitrile (ABS) is widely used. In order to meet the fire protection requirements in the actual use of PC / ABS, research on environmentally friendly flame-retardant PC / ABS alloys has become the focus of this field. But at present, it is still difficult for such materials to achieve high-gloss spray-free coating, and the ...
