Abstract

The invention discloses an inorganic particle reinforced PC / PET alloy. The alloy comprises the following components in percentages by weight: 40% to 60% of PC, 5% to 30% of PET, 10% to 20% of inorganic particles, 2% to 5% of a compatilizer, 0.5% to 2% of a light stabilizer, 0.5% to 1% of a coupling agent, 0.1% to 0.5% of a main antioxidant, 0.1% to 0.5% of an auxiliary antioxidant and 0.5% to 2% of a lubricating agent. The inorganic particle reinforced PC / PET alloy has the beneficial effects that, compared with the prior art, the alloy has advantages of PC and PET, the defects of a single component on the performance are compensated, the alloy also has the characteristics of high strength, high rigidity, high heat resistance, high corrosion resistance, high weather resistance, excellent electrical performance and processability and the like, and the cost is also relatively low, so that the alloy has excellent application prospects in the fields of automobile industry, electric products, mechanical parts and buildings.

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...
