Abstract

The invention discloses an anti-corrosion sewage pipeline material which contains the following raw materials in parts by weight: 10-30 parts of polybutylene, 20-40 parts of polypropylene, 3-10 parts of an unsaturated polyester resin, 3-7 parts of brucite, 2-4 parts of liquid acrylonitrile-butadiene rubber, 1-5 parts of calcium lignosulphonate, 1-2 parts of dipentaerythritol diphosphite, 2-15 parts of fatty alcohol-polyoxyethylene ether, 5-15 parts of di-iso-decylphthalate, 3-9 parts of a nonionic surfactant, 2-4 parts of a plasticizer and 2-10 parts of a preservative. The anti-corrosion sewage pipeline material disclosed by the invention is capable of conveying sewage and preventing pipelines from corrosion, the unsaturated polyester resin is used as one of the raw materials, the unsaturated polyester resin is a thermoplastic synthetic resin with excellent properties and has characteristics of being small in specific gravity, free of toxin and easy to process, and thus a pipeline is good in impact resistance and torsion resistance.

Description

technical field [0001] The invention belongs to the field of pipeline materials, and in particular relates to an anti-corrosion sewage pipeline material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy, our environment has also been damaged to varying degrees, among which water pollution is particularly serious. The sewage mainly comes from various industries such as chemical energy, metal smelting, automobiles, and medicine. Although it will be discharged to a certain standard after certain treatment, it will still contain a large amount of acid and alkali, heavy metal ions, and bacteria. During the drainage process, the pipeline will be continuously corroded and infected, shortening the life of the pipeline, which is not only not environmentally friendly, but also uneconomical, and will waste more manpower and material resources. Therefore, it is of great significance for energy saving and environme...
