Abstract

The invention discloses an inorganic particle reinforced PC / PET alloy, which comprises the following components by mass percentage: 40%-60% of PC, 5%-30% of PET, 10%-20% of inorganic particles, 2%-5% of a compatibilizer, 0.5%-2% of a light stabilizer, 0.5%-1% of a coupling agent, 0.1%-0.5% of a main antioxidant, 0.1%-0.5% of an auxiliary antioxidant, and 0.5%-2% of a lubricant. Compared with the prior art, the inorganic particle reinforced PC / PET alloy prepared by the invention not only has the respective advantages of PC and PET, makes up for the performance defects of single component, but also has the advantages of high strength, good rigidity, excellent heat resistance and corrosion resistance, good weatherability, excellent electrical properties and processability, etc., and is low in cost, thereby having very good application prospects in automobile industry, electronic appliances, mechanical parts, building and other fields.

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...
