Problems solved by technology

However, the pure PC melt has a high viscosity and is not easy to process. The modulus is only 2000-3000MPa. In the application, inorganic fillers need to be added to increase the modulus.
[0003] However, although the processing of inorganic fillers will increase the modulus, it will seriously reduce the impact strength and elongation at break of PC.
[0004] In view of this, it is necessary to develop an inorganic filled PC composite material to solve the problem that the impact strength and elongation at break of the prior art PC are seriously reduced after adding inorganic fillers.

Abstract

The invention specifically relates to a PC composite material filled with an inorganic filling material and a product thereof, belonging to the technical field of high polymer materials. The PC composite material filled with the inorganic filling material comprises PC resin, a flexibilizer, a fire retardant and the inorganic filling material. The product is produced by molding the PC composite material filled with the inorganic filling material. Through addition of the compound flexibilizer, the PC composite material can retain excellent impact strength and elongation at break after addition of the inorganic filling material.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to an inorganic filled PC composite material and its products. 【Background technique】 [0002] PC is a kind of engineering plastic with good impact resistance, which is widely used in electronic and electrical products. However, pure PC has a high melt viscosity and is not easy to process. The modulus is only 2000-3000MPa, and inorganic fillers need to be added to increase the modulus during application. [0003] However, although the processing of inorganic fillers will increase the modulus, it will seriously reduce the impact strength and elongation at break of PC. [0004] In view of this, it is really necessary to develop an inorganic filled PC composite material to solve the problem of severe decrease in impact strength and elongation at break of PC in the prior art after adding inorganic fillers. 【Content of invention】 [0005] Therefore, the object of the pres...
