Problems solved by technology

[0003] During the polymerization process of PC and ABS, due to the difference in polarity and interface between different polymers, between polymers and glass fibers or other inorganic functional fillers, there is a lack of physical entanglement between the components, so that they are compatible Poor, the resulting polymer alloys are difficult to really play their respective advantages, the compatibility of PC / ABS alloys in the prior art needs to be improved, in order to improve the compatibility between each component, give full play to PC, ABS Respectively good rigidity and toughness, in order to improve the wear resistance of PC / ABS alloy, the addition of compatibilizer and impact modifier is extremely important

Embodiment 1

[0023] A highly compatible PC / ABS engineering plastic, composed of the following components by weight percentage: aromatic polycarbonate (PC): 35.5%; acrylonitrile, butadiene, styrene terpolymer (ABS): 57.5% ; Compatibilizer A: 0.5%; Compatibilizer B: 1%; Impact modifier: 5.0%; Lubricant: 0.5%.

[0024] The compatibilizer 1 is an oxazoline compatibilizer, and the compatibilizer 2 is nanometer calcium carbonate. The ratio of the compatibilizer A to the compatibilizer B is 1:2; the lubricant is TAF; the impact modifier is a ternary compound of methyl methacrylate, butadiene and styrene Copolymer modifier.

[0025] The lubricant TAF is based on ethylene bisfatty acid amide (EBS). Under the action of a catalyst, reactive monomers containing polar groups react with EBS to form a BAB type copolymer, which maintains both It not only improves the lubricity of EBS, but also has polar groups that can combine with some polar groups on the surface of glass fibers and inorganic fillers, ...

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high wear resistance PC / ABS engineering plastic. Background technique [0002] PC plastic is a thermoplastic with a transparency of up to 90%. It not only has good rigidity and high toughness, but also has the advantages of high impact strength and high dimensional stability. ABS is a copolymer of acrylonitrile, butadiene and styrene. A blend, or terpolymer, is a tough and rigid thermoplastic. As an alloy of two plastics, PC / ABS engineering plastic combines the excellent characteristics of the two materials. It is widely used in automotive trims, household appliances, electronic product casings, etc., especially the popularity of electronic products in daily life. The wear resistance of materials used in this field has put forward new requirements. [0003] During the polymerization process of PC and ABS, due to the difference in polarity and interface between diffe...
