Embodiment 1

[0033] Take PC-ABS resin raw material, PMMA, CPE, graft copolymer, toughening agent and other components, and blend all the raw materials according to the following composition formula:

[0034] (a) 63 parts of PC-ABS resin raw material

[0035] (b) PMMA 24 parts

[0036] (c) 4 copies of CPE

[0037] (d) ABS-g-MAH 3 parts

[0038] (e) MBS 6 copies

[0039] Then the blended material is mixed and granulated in the extruder, and the obtained mixed and granulated product is made into a finished product through injection molding. Finally, the mechanical properties and surface hardness of the finished product are tested according to the national standard GB13525 / T-92. The results are shown in the table 1.

Abstract

The present invention relates to one kind of modified PC-ABS resin with high surface hardness. The recipe of the modified PC-ABS resin consists of PC-ABS resin 60-85 weight portions, PMMA 12-25 weight portions, CPE 1-5 weight portions, graft copolymer 1-5 weight portions, and toughener 1-7 weight portions. The modified PC-ABS resin has high surface hardness, mechanical performance basically the same as that of PC-ABS resin, lowered processing cost, and expanded application fields.

Description

technical field [0001] The invention relates to the field of thermoplastic resin compositions in polymer material technology, in particular to a modified formula of PC (Polycarbonate, polycarbonate)-ABS resin with high surface hardness. Background technique [0002] PC-ABS resin is an engineering plastic with superior comprehensive performance developed in the 1960s. It not only has the heat resistance, mechanical strength and dimensional stability of PC, but also has the advantages of easy processability and low price of ABS resin. Good performance, reasonable cost performance, widely used in the automotive industry, household appliances, daily necessities and other fields. Since PC-ABS resin is widely used in the panel production of electronic and electrical products, in order to maintain the long-term shape and aesthetic appearance of the panel, it has a higher surface hardness requirement. In the previous process, the method of surface spraying was used to improve the s...
