Wood grain-like PVC pipe and preparation method thereof

The invention belongs to a new material and a processing method, and particularly relates to a wood-grain-like PVC pipe and a preparation method thereof. The wood-grain-like PVC pipe comprises color masterbatch A, color masterbatch B and a base material, wherein the color masterbatch A comprises chlorinated polyvinyl chloride, a calcium-zinc stabilizer, a lubricant, a processing aid, an ultraviolet light absorber, an antioxidant and toner; the color masterbatch B comprises PVC resin, EVA wax, a calcium-zinc stabilizer, a plasticizer, a processing aid, a lubricant, a dispersant, an ultraviolet light absorber, an antioxidant and toner; the base material comprises PVC resin, a calcium-zinc stabilizer, CPE, calcium carbonate, a processing aid and a lubricant. The wood grain-like PVC pipe prepared by the invention not only has a wood grain shape, but also is good in heat resistance and high in tensile strength. 本发明属于一种新材料及加工方法，具体涉及一种仿木纹PVC管材及其制备方法，包括色母A、色母B和基体材料，所述色母A包括氯化聚氯乙烯、钙锌稳定剂、润滑剂、加工助剂、紫外线吸收剂、抗氧剂和色粉；所述色母B包括PV
