Abstract

The invention discloses an inorganic particle reinforced PC/PET alloy. The alloy is prepared from the following components in percentage by mass: 40-60 percent of PC, 5-30 percent of PET, 10-20 percent of inorganic particles; 2-5 percent of compatilizer, 0.5-2 percent of a light stabilizer, 0.5-1 percent of a coupling agent, 0.1-0.5 percent of a main antioxidant, 0.1-0.5 percent of an auxiliary antioxidant and 0.5-2 percent of a lubricating agent. Compared with the prior art, the inorganic particle reinforced PC/PET alloy has the advantages of PC and PET to make up the defect in single-component performance, and has the characteristics of high strength, good rigidity, excellent heat-resistant and corrosion-resistant performance, good weather resistance, excellent electric performance, excellent processing performance and the like. The inorganic particle reinforced alloy material is low in cost, and has a good application prospect in the fields of automobile industry, electronic appliances, mechanical parts and components, constructions 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...
