Abstract

The invention relates to a plastic product material which comprises the following components in parts by weight: 90-100 parts of polyethylene terephthalate, 100-120 parts of polylactic acid, 150-160 parts of polycarbonate, 20-30 parts of polycaprolactam, 50-60 parts of polyphenyl thioether, 30-40 parts of ethylene-acrylate-glycidyl methacrylate copolymer, 25-35 parts of modifier and 1-10 parts of mixed filler composed of calcium carbonate, kaolin and talcum powder in a weight ratio of 1.2:1.5:3. The polyethylene terephthalate, polylactic acid, polycarbonate, polycaprolactam, polyphenyl thioether, ethylene-acrylate-glycidyl methacrylate copolymer, modifier and mixed filler composed of calcium carbonate, kaolin and talcum powder are reasonably proportioned to enhance the mechanical properties of the material, thereby improving the compatibility and greatly enhancing the mechanical properties of the composite material.

Description

Technical field [0001] The invention relates to a plastic product material and belongs to the field of plastics. Background technique [0002] Polycarbonate (PC) is a thermoplastic material with excellent performance. It has excellent impact properties, chemical resistance and dimensional stability. It has a wide range of applications in electronic products, such as mobile phones and computer casings. However, polycarbonate materials cannot be degraded, which is not conducive to environmental protection. [0003] Polylactic acid (PLA) is a green material derived from plants, made from the fermentation products of agricultural cash crops (jade, cassava, etc.) as basic raw materials. It has good biodegradability and can be completely degraded into carbon dioxide and water after use. , Will not pollute the environment. Polylactic acid has good mechanical properties, thermoplasticity, fiber-forming properties, and high transparency. It is suitable for blow molding, extrusion, injecti...
