Abstract

The invention provides a method for manufacturing a recycled propene polymer (PP) and recycled poly ethylene (PE) wood-plastic greenhouse framework material. The method comprises the steps of mixing wood meal, recycled PP plastics, recycled PE plastics, an antioxidant, filler, a lubricant, a coupling agent and toner, heating the raw materials to 80-90 DEG C, performing heat preservation for 5-10 min, and performing cold mixing for 5-10 min. According to the method, the shortcomings that an existing greenhouse framework material is insufficient in rigidity and toughness are overcome, the prepared greenhouse framework material has the advantages of high rigidity and high toughness and is good in outdoor weather resistance and excellent in deformation resistance, and resources are recycled.

Description

technical field [0001] The invention relates to the field of environmental protection materials, in particular to a method for making recycled PP and PE wood-plastic greenhouse frame materials. Background technique [0002] The skeleton materials for building greenhouses are traditionally bamboo, plastic pipes, steel pipes, etc. Greenhouses built with bamboo have a short lifespan, greenhouses built with plastic pipes are easily deformed, steel pipes are prone to rust and the construction cost is high, and wood-plastic materials are used as the skeleton of the greenhouse. Damage to the insulation film and other advantages. [0003] Wood-plastic material is a composite material filled with thermoplastic polymers with wood powder, wood fiber or other plant fibers. It has the advantages of waterproof, anti-corrosion, insect-proof, and sun-resistant when used outdoors. [0004] Common wood-plastic materials used in the field of decorative building materials focus on improving r...
