Description

technical field

[0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a PVC wood-plastic foam material and a preparation method thereof. Background technique

[0002] Wood-plastic composite material is a new type of environmentally friendly composite material that uses wood powder, bamboo powder, fruit shell powder or crop straw powder and plastic resin or waste plastic as the main raw materials, and is mixed and formed at high temperature. Compared with log materials, wood-plastic composite materials have better aging resistance, water absorption resistance and warping resistance. At the same time, they can prevent moths and corrosion, and do not require anti-corrosion treatment to reduce environmental pollution, and the cost is 40-40% lower than pure wood or plastic. 60%, can be processed into various hollow profiles, so wood-plastic composites are widely used in many fields, and it is a new type of material with the most...
