Abstract

The invention provides a drainage pipe and a manufacturing method thereof and relates to the technical field of plastic pipes. Raw materials of the drainage pipe include, by weight, a composite stabilizer, ACR resin, stearic acid, PE wax, titanium dioxide, PVC-SG5 resin, nanometer active calcium carbonate, natural rubber, polyurethane rubber, ceramic fibers, an antioxidant, a compatilizer, a plasticizer and a curing agent. The method includes (1) weighing the raw materials, (2) mixing the raw materials, (3) performing plastification and granulation, (4) extruding a pipe blank material, (5) cooling and forming a pipe in vacuum and (6) pulling the pipe. The drainage pipe and the method overcome a problem that present drainage pipes have low strength, poor toughness and poor oxidation resistance.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, in particular to a drainage pipe and a preparation method thereof. Background technique [0002] At present, PVC pipes are mostly used for drainage pipes. At present, the production of PVC pipes mostly follows the production method in the 1990s. The materials used to make plastic pipes are divided into two types. One is made of PVC and ordinary calcium carbonate as the main raw materials. The cost of the pipe is high, and other properties such as strength, toughness, oxidation resistance and other physical and chemical properties are average; the other is to use recycled PVC plus calcium carbonate as the main raw material, although the cost of the manufactured pipe is low, but the production The resulting PVC pipes have poor physical and chemical properties such as strength, toughness, and oxidation resistance. SUMMARY OF THE INVENTION [0003] In order to solve the problems of low stren...
