Abstract

The invention discloses a plastic pipe for chemical wastewater delivery and a production method of the plastic pipe and relates to the technical field of plastic pipe production. The plastic pipe is prepared from raw materials in parts by mass as follows: 85-90 parts of a tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer, 20-25 parts of polyphenylene sulfate, 12-15 parts of nano silicon carbide, 10-13 parts of polyvinyl alcohol, 7-9 parts of white carbon black, 5-8 parts of diatomite, 3-5 parts of seaweed gel, 3-5 parts of epoxidized soybean oil, 2-3 parts of calcium stearate, 2-3 parts of zinc stearate, 1-3 parts of graphite powder, 1-3 parts of dibutyl phthalate, 0.5-2 parts of an ultraviolet light absorber, 30-40 parts of polyethylene glycol and 40-45 parts of water. The plastic pipe produced with the method has excellent wear resistance, corrosion resistance, high-temperature resistance, shock resistance and the like, adhesion to the inner wall is avoided, and the plastic pipe is prevented from being blocked after long-term usage, so that the plastic pipe is long in service life, wide in application range and applicable to delivery of all kinds of chemical wastewater.

Description

Technical field: [0001] The invention relates to the technical field of plastic pipe production, in particular to a plastic pipe for transporting chemical wastewater and a production method thereof. Background technique: [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight, corrosion resistance, high temperature resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Advantages, widely used in building water supply and drainage, urban water supply and drainage, city gas and agricultural irrigation and other fields. [0003] Especially in the chemical industry, sometimes it is necessary to use pipelines to transport high-temperature, corrosive and highly oxidative wastewater, which requires the plastic pipes used to have strong comprehensive performance, long service life, good stabilit...
