Problems solved by technology
[0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has good comprehensive properties, high mechanical strength, good impact toughness, stable size, and good electrical insulation; but PC also has high melt viscosity, poor fluidity, and solvent resistance. Poor resistance, prone to stress cracking and swelling in solvent and alkaline environment, more sensitive to notch, prone to stress cracking during processing, and the processing temperature is higher

A PC alloy material belongs to the field of high-polymer materials. The PC alloy material is made of main raw materials including, by weight part, 60-70 parts of PC resin aggregates, 10-28 parts of PET (polyethylene terephthalate) slices, 1-4 parts of lubricant, 10-30 parts T filler, 0.5-2.0 parts of antioxidant, 0.5-1.5 parts of solvent resisting agent, 2.0-5.0 parts of polyvinyl chloride and 0.5-2.0 parts of other auxiliaries. By improving polycarbonate and alloy, the PC alloy material can enhance the properties such as resistance to oxidation and corrosion; by adding in the polyvinyl chloride, the PC alloy material can further enhance the stability.
Description
technical field [0001] The invention belongs to the field of polymer materials, in particular to a PC alloy material. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has good comprehensive properties, high mechanical strength, good impact toughness, stable size, and good electrical insulation; but PC also has high melt viscosity, poor fluidity, and solvent resistance. Poor resistance, prone to stress cracking and swelling in solvents and alkaline environments, more sensitive to notches, prone to stress cracking during processing, and the processing temperature is higher. It is a relatively effective and convenient modification method to select special polyester to improve the performance of PC and obtain composite materials with excellent comprehensive properties. In the process of use, its corrosion resistance and oxidation resistance have always attracted more attention. Contents of the invention [0003] In orde...
