Abstract
The invention relates to the technical field of preparation of a PE pipeline material and provides a high-toughness PE pipeline material which is composed of, by weight, 50-70 parts of PE, 8-15 partsof PVC, 40-50 parts of polysulfide rubber, 40-50 parts of polybutyl acrylate, 20-30 parts of TPV, 8-15 parts of a silane coupling agent, 1-2 parts of ethyl phosphite, 8-15 parts of cardanol, 5-10 parts of hydroxy silicone oil, 10-15 parts of epoxy resin, 15-20 parts of polyoxymethylene, 10-15 parts of melamine, 1-3 parts of a stabilizer, 20-30 parts of lubricating oil, 0.1-1 part of turpentine, and 0.1-2 parts of toner. The PE pipeline material is prepared by modifying the PE, the polysulfide rubber and the polybutyl acrylate and then feeding the components into a mixing mill, then adding other raw materials, including the TPV and the modifier, and mixing all the materials. The PE pipeline material has excellent flexibility, impact strength, oxidization resistance, weather resistance and wearing resistance. The material is suitable for various pipelines.
Description
technical field [0001] The invention belongs to the technical field of PE pipe material preparation, in particular to a high-toughness PE pipe material. Background technique [0002] At present, the common pipe materials on the market are made of PE materials, such as building water supply, drainage, urban water supply, drainage, building heating, gas transmission, electrical and telecommunications protection casings, agricultural irrigation, industrial water delivery, etc. PE pipes. However, the general PE material needs to be further improved in terms of flexibility, impact resistance, weather resistance, aging resistance, etc., so as to be more suitable for pipeline materials in various occasions. Contents of the invention [0003] The purpose of the present invention is to provide a high-toughness PE pipe material to solve the problems that the performance of the current PE pipe material needs to be further improved in terms of flexibility, impact resistance, weather ...
