Problems solved by technology

[0003] Compared with pure PC / ABS, glass fiber reinforced PC / ABS has the advantages of high strength, high rigidity, good stress crack resistance, high heat resistance and good electrical properties, but glass fiber reinforced PC / ABS has the advantages of rigidity, strength, etc. While improving, its impact strength is significantly reduced
The use of inorganic powder for filling will also lead to a significant decrease in the impact toughness of the material, which restricts the development of inorganic filled PC / ABS products in products with high toughness requirements

Abstract

The invention relates to the technical field of a macromolecular material, and particularly relates to a high-performance mineral-filled PC / ABS alloy material and a preparation method thereof. The high-performance mineral-filled PC / ABS alloy material is prepared from the following raw materials in parts by weight: 60-80 parts of bisphenol A type PC, 20-40 parts of master batch, 1-4 parts of a compatible flexibilizer, 0.1-0.2 part of an antioxidant, 0.2-0.3 part of a lubricating agent and 0.4-0.8 part of a silane coupling agent, wherein the master batch is a mixture consisting of talcum powder, a coupling agent and ABS according to amass ratio of (45-55) to (1-3) to (45-55). The high-performance mineral-filled PC / ABS alloy material disclosed by the invention is good in impact toughness and therefore the comprehensive performances of the material is comprehensively guaranteed. By adopting a secondary commixing technique, the preparation method of the high-performance mineral-filled PC / ABS alloy material has the advantages that inorganic fillers can be uniformly orientated and distributed inside a base body, so that the modulus, strength and heat resistance of the alloy material are improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-performance mineral-filled PC / ABS alloy material and a preparation method thereof. Background technique [0002] Although PC is an engineering plastic with excellent comprehensive performance, it also has some defects: such as high melt viscosity, easy stress cracking, high notch sensitivity, etc. Therefore, it is necessary to study the modification of PC materials. At present, PC / The modification direction of ABS alloy has been extensively studied: in order to improve the performance of a certain aspect of PC / ABS alloy or reduce its production cost, in most cases, fillers such as inorganic powder or fiber in different proportions are added to the alloy for modification. Among them, glass fiber is the most widely used. [0003] Compared with pure PC / ABS, glass fiber reinforced PC / ABS has the advantages of high strength, high rigidity, good stress crack resistan...
