Abstract

The invention provides an anti-scaling high-concentration organic wastewater transport modified pipe and a preparation method thereof. The anti-scaling high-concentration organic waste water transport modified pipe comprises the following raw materials in parts by weight: high-density polyethylene resin 75 -90 parts, 12-19 parts of fluorine-containing polymethyl epoxy acrylate polymer and 1-7 parts of hydrophobically modified nano silicon dioxide. The fluorine-containing polymethyl epoxy acrylate polymer in the present invention is obtained by two-step bulk polymerization of hexafluorobutyl methacrylate, butyl methacrylate and glycidyl methacrylate, and it has good resistance Scaling performance, acid and alkali resistance, and no organic solvents are added during the preparation process, green and environmentally friendly, and it has good compatibility when blended with high-density polyethylene resin and hydrophobically modified nano-silica, effective The invention solves the problems of poor antifouling performance on the material surface, easy secondary pollution and easy fouling in the prior art, and is convenient for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of transport pipes and their preparation, and in particular relates to a modified pipe for transporting high-concentration organic wastewater that prevents scaling and a preparation method thereof. Background technique [0002] High-concentration organic wastewater has the characteristics of large pollution load and complex composition. It usually needs to be collected by the pipeline system and transported to the treatment facility for advanced treatment to meet the standard before discharge. Commonly used wastewater transportation pipes are mainly polyvinyl chloride (PVC) and high-density polyethylene (HDPE) materials. The former mainly includes lead salt stabilizers, acrylate processing aids, calcium carbonate fillers, lubricants, etc. The latter mainly adds fillers such as coupling agents, antioxidants, calcium carbonate, and carbon black, among which carbon black and calcium carbonate fillers are very h...
