Abstract

The invention discloses a plastic pipe material with good anti-corrosion and anti-ageing properties. The plastic pipe material with good anti-corrosion and anti-ageing properties is composed of, by weight part, 60-100 parts of polylactic acid, 20-40 parts of polyvinyl chloride, 40-70 parts of polypropylene resin, 8-18 parts of low-melting-point metal powder, 12-20 parts of vinyl acetate, 10-20 parts of Ni-Cr alloyed powder, 4-12 parts of flexibilizer, 2-5 parts of zinc oxide, 0.8-1.5 parts of odor adsorbent, 3-8 parts of polysaccharide alginate, 1-5 parts of chitosan quaternary ammonium salt,3-10 parts of anti-ageing agent, 1.5-6 parts of antioxidant, 8-16 parts of plant fiber. The plastic pipe material with good anti-corrosion and anti-ageing properties has the advantages of high corrosion resistance and high ageing resistance.

Description

technical field [0001] The invention relates to a plastic pipe material, in particular to a plastic pipe material with good corrosion resistance and aging resistance. Background technique [0002] In the current urban construction, urban underground pipe corridors are becoming more and more important and developed, and correspondingly, the requirements for various performance indicators of plastic pipe materials are also getting higher and higher, especially in terms of anti-corrosion and anti-corrosion properties. aging performance. However, the current plastic pipe materials are not ideal in terms of anti-corrosion performance and anti-aging performance, and are susceptible to corrosion and aging during the use of the pipe gallery. Contents of the invention [0003] The object of the present invention is to provide a plastic pipe material with good anti-corrosion and anti-aging properties. The pipeline material of the invention has the characteristics of strong anti-co...
