Problems solved by technology

When the AN content increases, the polarity of ABS will be greatly enhanced, and the spray paint resistance will also be improved, but at the same time, the compatibility of PC/ABS will be reduced. According to research in the literature, when the AN content is 25%, the PC/ABS The compatibility of PC/ABS is the best, but the chemical resistance of PC/ABS is average at this time;

Abstract

The invention provides a PC/ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) composition with a good paint spraying property and a preparation method of the PC/ABS composition. The composition is prepared from the following components in parts by weight: 50 to 80 parts of PC resin, 10 to 40 parts of ABS resin, 3 to 5 parts of talcum powder, 0.1 to 1 part of an antioxidant and 0.1 to 1 part of a lubricant. Compared with the prior art, the PC/ABS composition provided by the invention has the characteristics that the talcum powder is added so that the PC/ABS composition is separated out on the surface of a part in an injection molding process, the paint etching resisting capability of the part is improved and the problems of low fitting and cracking in a paint spraying process are solved; meanwhile, PC/ABS is properly etched through paint so that the bonding force after the paint spraying is guaranteed; the prepared PC/ABS composition has good paint spraying property and the bonding force of the paint is high.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to the field of spraying polymers, in particular to the field of improving the spraying corrosion resistance of PC / ABS materials, and in particular to a PC / ABS composition with excellent paint spraying properties and a preparation method thereof. Background technique [0002] PC / ABS alloy has excellent mechanical and thermal properties, and is widely used in automobiles, home appliances, digital products and other fields. Since the PC molecular chain contains ester groups, it is easy to absorb water and has poor chemical resistance stability, especially not alkali resistance, and it is easy to saponify and degrade in a weak alkali environment. In addition, the steric hindrance of PC is relatively large, and residual stress is prone to appear in the parts. ; And because of the existence of rubber PB, ABS is easily etched when painting. When PC / ABS is sprayed with some highly corrosi...
