Abstract

The invention discloses a high-mechanical-performance anti-aging PC / ABS alloy comprising the components by the mass percentage: 50%-70% of PC, 20%-30% of ABS, 5%-15% of a glass fiber, 2%-10% of glass micro-beads, 0.5%-2% of an anti-aging agent, 2%-5% of a toughening compatilizer, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The high-mechanical-performance anti-aging PC / ABS alloy has the beneficial effects that excellent performance of PC and ABS are synthesized, at the same time, the glass fiber and the glass micro-beads are adopted for synergistic enhancement, and proper amounts of the anti-aging agent and the toughening compatilizer are added, so that the PC / ABS alloy system has mechanical strength, chemical properties and electrical properties greatly improved, also has the advantages of excellent anti-aging performance, excellent stable performance, good processing performance and low cost, and can be widely used in electronic and electrical appliances, automobiles, machinery parts and components, medical apparatus and instruments and other fields.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an anti-aging PC / ABS alloy with high mechanical performance. Background technique [0002] Polycarbonate (PC) is a kind of engineering plastic with excellent performance, which has outstanding impact toughness, wide service temperature range and good electrical insulation, and has been widely used in automobile and electronic appliances industry. However, PC has high melt viscosity, difficult molding and processing, especially large-scale products are prone to stress cracking, poor chemical resistance, and high price, which limits the application of PC to a certain extent. The performance of ABS resin (acrylonitrile-butadiene-styrene copolymer) is between engineering plastics and general-purpose plastics. It has good impact resistance and processing performance, and the price is relatively cheap, but its heat resistance and weather resistance are poor. , The mechanical...
