Abstract

The invention provides a processing method of a high-toughness PVC pipe, and relates to the field of PVC pipes, wherein the high-toughness PVC pipe comprises the raw materials: PVC resin, dibutyl phthalate, paraffin, calcium carbonate, a stabilizer, a lubricant, an auxiliary agent and quartz sand. Through design of the processing method of the high-toughness PVC pipe, calcium carbonate is added into PVC; calcium carbonate is ground into micro calcium carbonate powder with different particle sizes, namely different lengths, through a stirring mechanism and a grinding mechanism; then the micro calcium carbonate powder is uniformly added into the raw materials and mixed and stirred with the raw materials; the high strength and high toughness of the PVC pipe can be improved through different regular arrangement of the calcium carbonate in the raw materials; compared with a pipe produced according to a common formula, the weather resistance of the pipe is remarkably improved, the impact strength of the pipe is improved, and the hydraulic strength and the aging resistance of the pipe are improved.

Description

technical field [0001] The invention relates to the field of PVC pipes, in particular to a processing method for high-toughness PVC pipes. Background technique [0002] The main component of PVC is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. [0003] PVC pipe is a type of pipe mainly composed of polyvinyl chloride. At present, PVC pipes are widely used in power cable laying and other fields. However, PVC pipes have poor pressure resistance and insufficient strength. These shortcomings not only limit its use, but also bring certain hidden dangers to subsequent use. Therefore, it is the problem to be solved by the present invention to provide a processing method for high-toughness PVC pipes. Contents of the invention [0004] The object of the present inv...
