Abstract

The invention discloses a municipal drainage pipeline and a preparation process thereof and a connection structure of the drainage pipeline. According to the technical scheme, the municipal drainage pipeline is characterized by comprising, sequentially from inside to outside, an oxide layer and a reinforcing layer; the oxide layer is made from, by weight, 30-50 parts of medium-alkali glass fiber,5-20 parts of epoxy acrylate microcapsules, 5-10 parts of bronopol, 5-10 parts of cyantraniliprole, 5-10 parts of Kevlar fiber, 5-10 parts of polyimide fiber, and 5-10 parts of pyromellitic dianhydride. In the municipal drainage pipeline according to the application, the medium-alkali glass fiber and the epoxy acrylate microcapsules act jointly, so that the municipal drainage pipeline has high structural strength and good properties.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a municipal sewage pipeline, a preparation process thereof and a connection structure of the sewage pipeline. Background technique [0002] Pipelines are important equipment for liquid transportation in modern industry. Traditional metal pipes and concrete pipes can no longer meet the needs of modern industry due to rust or high quality. [0003] The Chinese patent with the notification number CN10312289B discloses a glass steel pipe. The glass steel pipe has a double-layer structure, the inner layer is made of glass fiber reinforced magnesium oxychloride gel system, and the outer layer is made of resin-based glass fiber composite material. Made, wherein the magnesium oxychloride gelling system refers to a formula system that can be solidified within a certain period of time by adding various additives based on magnesium chloride aqueous solution and magnesium oxide. [0004] The f...
