Problems solved by technology

This patent uses silicon and acrylic surface regulators to coat the surface, protect the substrate, and achieve the effect of oleic acid and lactic acid resistance, but it is far from this patent in essence.
This patent does not use the change of hydrophobicity to achieve the effect of reducing the adhesion of stains, but only to avoid polluting substances from damaging the surface. From the final evaluation method of the patent, it can also be seen that the two patents have a large difference

Abstract

The invention relates to stain-resistant PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) alloy and a method for preparing the same. The stain-resistant PC / ABS alloy is prepared from raw materials including, by weight, 40-80 parts of polycarbonate, 10-50 parts of polyacrylonitrile-butadiene-styrene copolymers, 5-45 parts of stain-resistant PBT (polybutylene terephthalate) master batch, 0.5-3parts of compatibilizers, 0.1-1 part of antioxidants and 0.1-1 part of lubricants. The method includes placing the materials, except for the stain-resistant PBT master batch, into intermediate-speedmixers and mixing the materials with one another for 5-30 min to obtain mixed materials; feeding the mixed materials into twin-screw extruders, laterally feeding the stain-resistant PBT master batch into the twin-screw extruders, carrying out melt extrusion and carrying out granulation to obtain particles which are products. The stain-resistant PC / ABS alloy and the method have the advantages thatthe stain-resistant PC / ABS alloy can be prepared by the aid of the method, the good processing properties can be kept, and the products with high surface stain resistance can be produced by the aid ofthe industrial method.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a stain-resistant PC / ABS alloy and a preparation method thereof. Background technique [0002] PC / ABS alloy is a widely used engineering plastic with excellent impact strength, heat resistance and other properties, and is widely used in automobiles, electronics, home appliances and other fields. However, with the increase of application areas and the improvement of consumer demand, there are new requirements for the stain resistance of this material. Because PC / ABS itself has poor pollution resistance, it is necessary to modify the alloy to meet the requirements of pollution resistance. At present, there are many patents on PC / ABS alloys, but there is no such thing as a pollution-resistant PC / ABS. ABS alloy reports. [0003] Zeng Xiaoyuan et al. described in CN103469361A the introduction of fluorine-containing synthetic monomers to synthesize fluorine-containing PBT to prepare ...
