Abstract

The invention relates to the field of polymer materials, in particular to a PC / ABS alloy for a tail lamp shell. The PC / ABS alloy for a tail lamp shell is composed of the following components by weight: 40-80 parts of PC resin, 10-30 parts of ABS resin, 1-30 parts of SAN resin, 0.5-10 parts of a compatilizer, 0.5-5 parts of a chain extender, 0.1-1 part of a lubricant, and 0.1-1 part of an antioxidant. According to the PC / ABS alloy for the tail lamp shell and the preparation method thereof, the material is particularly suitable for a bonding process of friction vibration welding with a PMMA lampshade, and the PC / ABS alloy has very excellent welding slag yield.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy for a car tail light housing and a preparation method thereof, which is particularly suitable for the welding process of friction vibration welding with a PMMA outer cover, and is better than conventional PC / ABS alloys. It has a lower defective rate of welding slag, which reduces the quality cost of the product. Background technique [0002] Polycarbonate (PC) is a linear polycarbonate, an amorphous engineering plastic with good toughness, transparency and heat resistance. ABS has good fluidity and impact performance. Therefore, the blending of PC and ABS can combine the excellent properties of both PC and ABS, which can not only improve the heat resistance and tensile strength of ABS, but also reduce the melt viscosity of PC and improve the processing performance, so PC / ABS alloy It is a very suitable material for preparing tail lamp housings. [0003] The weld...
