Problems solved by technology

However, the difficulty of using three wastes to prepare wood-plastic composites is: waste PVC plastics have poor fluidity, it is difficult to add a high proportion of straw fibers and red mud to thermoplastic resins, and it is difficult for straw fibers to form a good interface with thermoplastic resins , seriously affect the performance of the material
For example, the patent of Chinese Patent Publication No. CN1872915A discloses a profile synthesized from plant fiber waste straw, which mixes waste straw powder with plastics and additives, extrudes and cools the shape, and the prepared plate has low strength and low water resistance.
The patent of Chinese Patent Publication No. CN104251055A discloses a preparation method of a new type of red mud wood-plastic formwork. The formwork prepared by this method has low strength and low waste addition

Abstract

A wood plastic composite and a preparing method thereof are disclosed. The wood plastic composite is prepared from crop straw, waste PVC plastic and red mud which are three wastes, and active nanometer calcium carbonate, pure PVC resin and other processing auxiliary agents are added. The wood plastic composite comprehensively utilizes the three wastes. Straw fiber has strengthening and toughening effects. The wood plastic composite filled by the red mud is high in durance and long in service lifetime. The wood plastic composite is high in strength, high in durance and good in waterproofness.

Description

technical field [0001] The invention relates to the field of wood-plastic composite materials, in particular to a wood-plastic composite template using waste resources and a preparation method thereof. Background technique [0002] Crop straw is agricultural and forestry waste produced in rural areas. The country produces tens of billions of tons of crop straw every year, and the pollution caused by "straw burning" has become a pollution problem that plagues the national air environment. It is particularly important to find a new way of comprehensive utilization for the treatment of crop straws. [0003] PVC material has non-flammability, high strength, resistance to climate change and excellent geometric stability, and is widely used in transportation, building materials, automobiles and other industries. With the wide application of PVC plastics, the treatment of waste PVC plastics has attracted people's attention day by day. Traditional burial and incineration occupy a...
