Problems solved by technology

[0004] However, PP plastic has poor toughness, outstanding low-temperature brittleness, poor impact resistance, and long degradation cycle is not conducive to environmental protection. At the same time, the prepared PP plastic injection molding machine does not have a screening structure when feeding, and the masterbatch with larger particles is extruded. Increased extrusion pressure is not conducive to the preparation of PP plastics

Abstract

The invention discloses a preparation method of environment-friendly PP plastic. The environment-friendly PP plastic is prepared from the following components in parts by weight: 58 to 88 parts of PP resin, 5 to 19 parts of plant fiber starch, 8 to 16 parts of calcium carbonate, 1.3 to 3 parts of nano titanium dioxide, 6.8 to 9.8 parts of silane coupling agent, 1 to 2 parts of nano silver oxide, 8 to 12 parts of graphene, 1 to 3 parts of nano zinc oxide, 8 to 18 parts of ethylene-vinyl acetate copolymer, 8 to 12 parts of 3-aminopropyltriethoxysilane and 10 to 15 parts of ethyl acetate. The PP resin, the plant fiber starch, the calcium carbonate, the nano titanium dioxide, the silane coupling agent, the nano silver oxide, the graphene, the nano zinc oxide, the ethylene-vinyl acetate copolymer, the 3-aminopropyltriethoxysilane and the ethyl acetate are used as raw materials for preparing the environment-friendly PP plastic, and the prepared environment-friendly PP plastic has the advantages of being high in toughness, low in low-temperature brittleness, high in impact resistance, short in degradation period, and beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a preparation method of environment-friendly PP plastic. Background technique [0002] Plastic has the advantages of wide application, good formability, and low price, and has been widely used. However, long-term use of plastics has serious aging and single functions, and general plastics have poor heat-resistant and antibacterial effects. Therefore, the development of functional plastics will have a huge market prospect. [0003] Polypropylene (PP) is a kind of thermoplastic resin prepared by propylene polymerization. It has the advantages of excellent physical properties, simple molding process, low density and rich source of raw materials. It has become the fastest growing and development potential among the five general-purpose synthetic resins The largest class of resins. According to statistics, the combined output of PP and polyethylene accounts for 35% to 50...
