Abstract

The invention discloses a leachate transport pipe and a preparation method thereof, belonging to the technical field of pipes. Leachate transport tubing includes the following raw materials: polymethylsiloxane epoxy acrylate, hydrophobically modified nano-silica, and high-density polyethylene. The surface of the leachate transportation pipe of the invention has good anti-scaling performance; the surface of the material has good wear resistance, and the hydrophobic performance of the material surface after abrasion is improved, and its anti-scaling performance is obviously better than that of ordinary high-density polyethylene materials. The preparation method of the invention is simple, and the synthesis of the siloxane acrylate polymer adopts a two-step bulk polymerization method, and the whole process does not use organic solvents, and has no pollution to the environment; It leads to the shortcoming of short service life, and the bulk polymer and the modified nanopowder in the blend system have the same functional group, which makes the blend system have good compatibility.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a leachate transport pipe and a preparation method thereof. Background technique [0002] Landfill leachate has the characteristics of a wide variety of pollutants and complex components. Generally, it needs to be collected by the pipeline system and transported to the corresponding treatment facilities for subsequent treatment. Commonly used leachate transport pipes are mainly high-density polyethylene (HDPE) materials, and the main additives include antioxidants, carbon black masterbatches, calcium carbonate, paraffin and other fillers, among which carbon black and calcium carbonate fillers have strong water absorption. During the transportation of leachate, this kind of pipe is likely to cause contamination on the inner wall of the pipe, and then scale, resulting in pipe blockage, which may cause the pipe to burst in severe cases. Scaling of leachate transportation pipelines se...
