Abstract

The invention relates to plasticization and granulation equipment for filling polyolefin plastic composite material with high-share plant fibers, which comprises a parallel twin-screw extruder, a slicing device, an air inducing system and a cyclone separation system, wherein the slicing device is designed into an open type and is arranged on the nose of the parallel twin-screw extruder; and the screw head of the parallel twin-screw extruder is directly communicated with the air. The air inlet of the air inducing system of the equipment is arranged right above the slicing device, and the feed opening of the cyclone separation system is arranged right below the slicing device. The invention provides plasticization and granulation equipment which is capable of well adapting to high-shared plant fiber filled polyolefin plastic composite material, and the equipment is not degraded and carbonized when the wood-plastic composite material with very high plant fiber content is plasticized and granulated, and has good devolatilization effect.

Description

technical field

[0001] The invention relates to plasticizing and granulating equipment capable of preparing wood-plastic composite materials with high plant fiber content. Background technique

[0002] Wood-plastic composite (WPC) is a new type of green and environmentally friendly new material that has emerged in recent years. There are many varieties of wood-plastic composite materials, among which polyolefin wood-plastic composite materials are currently the world's largest output of wood-plastic composite materials, and they are also the most environmentally friendly wood-plastic composite materials. Since the main raw materials for the production of polyolefin wood-plastic composite materials are agricultural and forestry waste (such as wood powder, bamboo powder, bran powder, straw powder and other plant fiber powder) and waste plastics (such as polyethylene, polypropylene and other polyolefins), its products It is mainly used as a substitute for wood. Therefore, the ...
