Problems solved by technology

[0003] In order to improve the modulus of PC / ABS composite materials, inorganic fillers are usually added to PC / ABS composite materials, but the notched impact strength after adding inorganic fillers is seriously reduced, especially at low temperatures, such as -20 ℃, which severely restricts the application of PC / ABS composites
[0004] In view of this, it is necessary to develop a low-temperature impact-resistant PC / ABS composite material to solve the problem that the notched impact strength of the PC / ABS composite material in the prior art is seriously reduced after adding inorganic fillers.

Abstract

The invention specifically relates to a PC / ABS composite with low-temperature impact resistance and a product thereof, belonging to the technical field of high polymer materials. The PC / ABS compositewith low-temperature impact resistance comprises organosilicon-copolymerized PC resin, ABS resin, a flexibilizer, a fire retardant and an inorganic filling material. The product is prepared by moldingthe PC / ABS composite with low-temperature impact resistance. According to the invention, the organosilicon-copolymerized PC resin and the compound flexibilizer with low-temperature impact resistanceare used for the PC / ABS composite, so the PC / ABS composite has excellent notch impact strength at a low temperature after addition of the inorganic filling material.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a low-temperature impact-resistant PC / ABS composite material and its products. 【Background technique】 [0002] PC / ABS composite materials are widely used in household appliances, automobiles and other fields, and have the advantages of easy processing and molding, and a wide range of adjustable physical properties. [0003] In order to improve the modulus of PC / ABS composite materials, inorganic fillers are usually added to PC / ABS composite materials, but the notched impact strength after adding inorganic fillers is seriously reduced, especially at low temperatures, such as -20 This severely limits the application of PC / ABS composites. [0004] In view of this, it is necessary to develop a low-temperature impact-resistant PC / ABS composite material to solve the problem that the notched impact strength of the PC / ABS composite material in the prior art is seriously redu...
