Problems solved by technology

[0007] However, because the wettability of PC to glass fiber is very poor, the two are not well compatible. Most of the products on the market, especially when the glass fiber content is above 20%, have low impact strength and do not have good performance. toughness

Abstract

The invention discloses a glass fiber toughened polycarbonate / polypropylene alloy material which is characterized by comprising the following components in percentage by weight: 100g of polycarbonate resin, 10-5g of polycarbonate resin, 5-20g of a polycarbonate grafted glycidyl methacrylate copolymer, 5-20g of an ethylene-methyl acrylate glycidyl methacrylate random copolymer, 0.1-1g of an antioxidant and 1-2g of a lubricant. The material disclosed by the invention has the advantages of better toughness and higher strength.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a polycarbonate alloy functional material prepared by toughening and strengthening polycarbonate by using glass fiber and polypropylene resin and a preparation method thereof Background technique [0002] Polycarbonate (PC) material has excellent performance, but PC has high melt strength, high viscosity, poor fluidity, processing performance and stability, high residual stress, prone to stress cracking, low impact resistance to notch, and poor wear resistance , Low adhesion to metal parts, affecting processing and injection molding and other shortcomings, thus limiting its use. [0003] Polypropylene resin (PP) has low density, rich sources of raw materials, and low price. By using PP to melt blend and modify PC, the melt viscosity of PC can be greatly reduced, thereby improving the molding performance and reducing its notch sensitivity. , while reducing it...
