Abstract

The invention relates to an inorganic particle reinforced polycarbonate / polyethylene terephthalate (PC / PET) alloy. The inorganic particle reinforced PC / PET alloy consists of the following raw materials in percentage by weight: 40-50% of PC, 0.1-1% of inorganic particles, 0.1-3% of barium ferrite, 0.1-3% of titanium nitride, 0.1-3% of zirconium carbide and 40-60% of PET. The beneficial effects arethat compared with the prior art, the inorganic particle reinforced PC / PET alloy provided by the invention not only has respective advantages of the PC and the PET and overcomes performance defects ofsingle component, but also has the advantages of high strength, good rigidity, excellent heat resistance and corrosion resistance, good weather resistance, excellent electrical performance and processing performance, and the like, and cost is low, so that the inorganic particle reinforced PC / PET alloy has a good application prospect in the fields of automobile industry, electronics, machinery parts, buildings and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an inorganic particle reinforced PC / PET alloy. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance. It has the advantages of high impact strength, creep resistance, good dimensional stability, heat resistance, transparency, and excellent dielectric properties. However, PC has high melt viscosity and poor fluidity. Poor solvent resistance, especially poor resistance to organic solvents and alkaline drugs, prone to stress cracking and swelling in solvents and alkaline environments, and sensitive to notches. Polyethylene terephthalate (PET) is a translucent crystalline thermoplastic polyester with high heat resistance, toughness, fatigue resistance, self-lubrication, low coefficient of friction, weather resistance, and is still Maintain various physical properties (including electrical properties), resist hot water, alkali...
