Plastic pipe preparation process

Abstract

The invention discloses a plastic pipe preparation process. The preparation method comprises the following steps: S1, preparing raw materials: selecting the following raw materials in parts by weight:40-70 parts of polypropylene resin, 50-70 parts of polyvinyl chloride resin, 30-60 parts of nano-scale antibacterial masterbatch, 1-4 parts of polytetrafluoroethylene resin, 1-2 parts of triphenyl phosphite, 2.5-3.5 parts of triethyl citrate, 1-5 parts of calcium carbonate, 1-5 parts of silicon powder, 2.2-2.8 parts of butyl stearate, 2-8 parts of bentonite, 1-3 parts of epoxidized soybean oil, and 1.2-1.6 parts of an antioxidant synergist; S2, preparing a first mixture; S3, preparing a second mixture; S4, extrusion molding. According to the process, the nano-scale antibacterial masterbatch is added, so that the plastic pipe has an antibacterial property, has a killing effect on bacteria in water, can inhibit the growth of the bacteria, keeps the water quality clean and sanitary, and hasexcellent mechanical property, flame retardance and antibacterial property by adding the polyvinyl chloride resin, the polypropylene resin and the polytetrafluoroethylene resin; in addition, the anti-aging, high-temperature-resistant and corrosion-resistant properties of the plastic pipe are stable.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to a preparation process of plastic pipes. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, added with stabilizers, lubricants, plasticizers, etc., and extruded in a pipe making machine by a "plastic" method. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in houses and buildings. However, there are still various plastic pipe preparation processes on the market. various problems. [0003] For example, the authorized announcement number is CN101844384A, which discloses a method for preparing large-diameter plastic pipe fittings. Although it realizes the constant pressure molding of the pipe fitting molding process, it improves the stability and consistency of the internal q...

Problems solved by technology

[0003] For example, the authorized announcement number is CN101844384A, which discloses a method for preparing large-diameter plastic pipe fittings. Although it realizes the constant pressure molding of the pipe fitting molding process, it improves the stability and consistency of the internal quality of the product; it has wide processing adaptability. characteristics, but it does not solve the existing problems of the existing plastic pipe preparation process: poor antibacterial performance, inconvenient antibacterial, reducing the cleanliness of water quality, low temperature resistance and corrosion resistance, and short service life. Therefore, we propose a plastic pipe preparation process
