Method for preparing PE water supply pipe

Abstract

The invention discloses a method for preparing a PE water supply pipe. The material formulation of the PE water supply pipe includes: polyethylene resin (PE), polyethylene wax (PE wax), nano carbon black, metallocene catalyst, antioxidant, and nano-silver antibacterial agent, wherein the mass ratio of the polyethylene resin (PE) is 45%, the mass ratio of the polyethylene wax (PE wax) is 25%, the mass ratio of the nano carbon black is 20%, the mass ratio of the metallocene catalyst is 6%, and the mass ratio of the antioxidant is 3%. According to the method for preparing the PE water supply pipeprovided by the invention, the metallocene catalyst and the nano-silver antibacterial agent are added into the formula raw material of the PE pipe, so that the strength and rigidity of the finished PE pipe are improved, the processing performance is improved, and the problem of bacteria breeding in the later stage of the PE pipe wall is solved; and in addition, by improving the production processof the PE pipe, a vacuum setting device is added in the process for preliminary cooling and sizing the PE pipe, and the regularity of the PE pipe is controlled more accurately.

Description

technical field [0001] The invention relates to the field of PE water supply pipes, in particular to a preparation method of PE water supply pipes. Background technique [0002] PE water supply pipe is a pipe made of polyethylene resin (PE) as the main material. PE pipe has become the best choice for water supply pipe due to its own advantages of impact resistance, aging resistance, corrosion resistance and wear resistance. It is a traditional steel pipe. Replacement products of pipes and PVC drinking water pipes; however, due to the single formula material of traditional PE pipes, it is easy to breed bacteria on the pipe wall after being used as a water supply pipe for a long time, and the strength of the pipe is easy to deteriorate over time. In addition, the traditional PE pipe production process is prone to irregularities in the surface of the pipe, which affects the quality of the entire pipe.
