Problems solved by technology

[0005] At the same time, a large amount of residual film is produced in the process of mulch film planting. At present, after recycling, plastic processing enterprises reuse it as recycled materials, but it is difficult to use it due to the difficulty of separating a large number of sundries mixed in it.

Abstract

The invention relates to a method for manufacturing wood plastic composite material by using plant straw and waste plastics and materials thereof. Polyester and plant wood fiber materials such as sawdust, bamboo powder, rice hull, straw, and the like, are mixed according to certain ratios, a tailor-made additive is added, and after the processes of high temperature, extrusion, molding, and the like, the composite building profile is manufactured. The wood plastic material can replace wood, plastics, and the like, and is mainly used in the industries of packaging, building materials, furniture, logistics, and the like. The invention has simple processing technology, and the product has good processing properties and strength property, good water proof and corrosion resistant property and adjustability, the materials have wide sources and applications, especially the plant straw and waste plastics which contain waste mulch film and are recovered under the northern planting pattern of mulch film can be used for production, thus using the waste and restraining the current pollution of the mulch film planting to the lands effectively.

Description

Technical field: [0001] The invention relates to a method of using plant straws to manufacture wood-plastic composite materials and the materials obtained by the method, in particular to a method mainly using plant straws containing old plastic films and waste plastic films recovered from the northern plastic film planting mode. A method for a wood-plastic composite material and a material obtained by the method. Background technique: [0002] At present, a large amount of straw produced by agricultural production is first crushed and returned to the field as fertilizer, but the long-term use of this treatment method will increase the possibility of crop diseases, and its utilization value is also low; second, it is used as fuel. The value is greatly reduced, and some are treated as waste, such as incineration, which not only causes waste of resources, but also pollutes the environment. [0003] Some people use it to make compressed fiberboard, and due to technological reas...
