Abstract

The invention reveals a PC / PET composite material and a product thereof. The PC / PET composite material comprises the following components by weight: 50-60 parts of PC resin; 20-30 parts of PET resin; 10-15 parts of talcum powder; 5-8 parts of a toughening agent; and 0.15-0.25 part of an antioxidant. According to the PC / PET composite material and the product thereof provided by the invention, a certain proportion of PET resin, talcum powder, the toughening agent and the antioxidant are added into PC resin, and substances are mixed together, the mixture is subjected to melt extrusion, and then granulation is carried out, so that the composite material molded product can be well applied to the field of auto parts, and the composite material molded product has the characteristics of high rigidity, high impact and low warpage, and good chemical resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PC / PET composite material and its products. 【Background technique】 [0002] Polycarbonate resin, abbreviated as PC, is a colorless and transparent amorphous thermoplastic material. Because it is easy to process, it is suitable for various molding methods such as injection, extrusion, and blow molding, and has good mechanical, Optical performance, widely used in many fields such as packaging, daily necessities, electronic appliances, toys, instruments, transportation and machine manufacturing. However, the disadvantage of polycarbonate resin is poor chemical resistance, that is, poor resistance to acids, alkalis, salts, solvents and other chemicals. [0003] Polyethylene terephthalate, abbreviated as PET, is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction resis...
