Abstract

The invention discloses a special weatherproof moldproof functional master batch for a wood / plastic composite material. The special weatherproof moldproof functional master batch for a wood / plastic composite material is prepared from the following components in percentage by mass: 30-55% of polyethylene or EVA (ethylene-vinyl acetate), 3-8% of ethylene bis stearamide, 2-7% of polyethylene wax, 8-15% of Tinuvin 360, 10-25% of ZnO, 5-10% of antioxidant 300, 5-15% of 4,5-dichloro-N-octyl-3-isothiazolinone and 5-15% of N-trichloromethylthiophthalimide. The invention can be widely used in various outdoor wood / plastic composite materials; the wood / plastic composite material with the functional master batch can be used outdoors for a long time; the functional master batch obviously solves the problem of discolorment of the wood / plastic composite material when the wood / plastic composite material is used outdoors, prevent the mold from growth, greatly prolongs the service life of the wood / plastic composite material; and the addition process is simple and convenient for operation, and does not produce dust pollution.

Description

Technical field: [0001] The invention relates to a functional masterbatch of a wood-plastic composite material and a preparation method thereof, in particular to a weather-resistant and mildew-proof functional masterbatch specially used for a wood-plastic composite material and a preparation method thereof. Background technique: [0002] Wood-Plastic Composite (WPC for short) is a new type of material made by mixing natural fibers with thermoplastic resin or other materials in a certain proportion, adding specific additives, and processing under high temperature and high pressure. Wood-plastic composite materials have the advantages of both plant fibers and thermoplastics, and have the characteristics of low price, good wood feeling, rich wood fiber materials, high specific strength and hardness, and effectively alleviate the contradictions of scarcity of forest resources and shortage of wood supply. , and plant fiber has the characteristics of renewability and biodegradabil...
