According to the preparation method of the water-resistant and high-strength PVC wood-plastic composite, all steps are reasonably matched, the process is simple, the method is easy to apply and popularize, and the prepared PVC wood-plastic composite has high mechanical strength, good water resistance, strong corrosion resistance, long service life, great market competitiveness and application value.

Description

technical field [0001] The invention belongs to the field of composite material processing, and in particular relates to a preparation method of a water-resistant high-strength PVC wood-plastic composite material. Background technique [0002] Wood is a commonly used material in people's daily life, but as wood is felled wantonly, wood resources are also in short supply, and wood has problems such as poor water resistance, poor corrosion resistance, and poor strength. [0003] Plastic is one of the essential raw materials in people's life now, but plastic is not easy to degrade, and the simple use of plastic is not conducive to environmental protection. [0004] In this regard, people compound plastic and wood together to make a wood-plastic composite material. This type of material not only has high strength quality, but also has good degradable quality. However, with the continuous improvement of people's requirements for material performance, the performance of such mate...
