Problems solved by technology

[0002] With the rapid development of modern industry, problems such as pollution and waste water have come one after another. At present, the treatment method of sewage is mainly through physical separation to recover the insoluble and suspended pollutants in waste water. For some pollutants dissolved in wastewater, the separation effect is not very good
Moreover, the pipelines in the wastewater separation device need to be replaced frequently due to the corrosion of wastewater, which is time-consuming and laborious

Abstract

The invention discloses a preparation method of a special wastewater treatment pipeline material, and relates to the technical field of pipeline materials. The preparation method of the pipeline material includes the steps: modified melamine copolymer resin preparation; toughening agent preparation; pipeline material preparation. The melamine copolymer resin synthesized by melamine, fluorine-containing polyether polyol and 15% formaldehyde solution has high resistance to cold, heat and wastewater corrosion and is good in weather resistance, stearic acid and p-hydroxybenzoic acid generate a toughening agent through esterification reaction, and toughness and structural strength of the pipeline material can be improved by the toughening agent. The pipeline material is resistant to corrosion and impact and particularly applicable to the field of wastewater treatment.

Description

Technical field: [0001] The invention relates to the technical field of pipeline materials, in particular to a preparation method of pipeline materials specially used for wastewater treatment. Background technique: [0002] With the rapid development of modern industry, problems such as pollution and waste water have come one after another. At present, the treatment method of sewage is mainly through physical separation to recover the insoluble and suspended pollutants in waste water. For some pollutants dissolved in wastewater, the separation effect is not very good. Moreover, the pipelines in the waste water separation device need to be replaced frequently due to the corrosion of the waste water, which is time-consuming and labor-intensive. Invention content: [0003] The technical problem to be solved by the present invention is to provide a corrosion-resistant and extrusion-resistant special pipeline material for wastewater treatment. [0004] Technical problem to be...
