Abstract

The invention relates to the field of polymer materials, specifically a PC / ABS alloy with high light-shielding, high weather resistance, anti-screw slipping and excellent antibacterial effect, which is composed of the following components in parts by weight: 40-70 parts of PC resin, 10-20 parts of SAN resin, 1-30 parts of high light-shielding titanium dioxide masterbatch, 1-20 parts of photocatalyst titanium dioxide masterbatch, 1-20 parts of toughening agent, 0.1-2 parts of dispersant, 0.1-1 part of antioxidant . The invention also provides a preparation method of the PC / ABS alloy. The alloy material of the invention has properties such as high light-shielding, high whiteness, high weather resistance, anti-slipping of screw posts and excellent antibacterial effect, and can be widely used in parts such as white home appliance casings.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / ABS alloy with high light-shielding, high weather resistance, anti-slipping of screw posts and excellent antibacterial effect and a preparation method thereof. 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. Therefore, PC / ABS alloy materials are widely used in white home appliance shells. Most of the shells of white goods are equipped with LED display lights. The white PC / ABS used in this field has high requirements for shading, whiteness, weather resistanc...
