Problems solved by technology

At this stage, resins such as PVC / PP / PE are often used to produce wood-plastic composite materials. However, due to the performance of these resin matrices, such as deformation resistance, impact strength, and scratch resistance, there is still a certain gap compared with PET. The preparation of wood-plastic composite materials and products through foamed PET polyester foam materials is expected to make wood-plastic composite materials obtain more superior performance, but because the melting temperature of PET is as high as 250 ° C, it is difficult to manufacture wood-plastic composite materials in the prior art. It is difficult to process and obtain wood-plastic composite materials and products with good performance, which limits the production and application of PET wood-plastic composite materials
The prior art lacks a kind of PET wood-plastic composite material manufacturing equipment, and also lacks a kind of operation method of PET wood-plastic composite material manufacturing equipment
