Description

technical field [0001] The invention relates to the technical field of materials, in particular to a PVC wood-plastic material. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics in the world. It has the advantages of high strength, low price, good chemical corrosion resistance, good electrical insulation and difficult to burn. The special structure of PVC makes it easy to remove the hydrogen chloride on the molecule when it is processed under high temperature and high shear conditions, resulting in polymer degradation, resulting in discoloration of the product and a decrease in the mechanical properties of the product, affecting its service life. [0003] Chinese invention patent publication number is the patent of CN108485111A, discloses a kind of PVC wood-plastic low-foaming particle material. The PVC wood-plastic low-foaming granular material comprises the following components by weight: 120-130 parts of polyvinyl chloride...
