Abstract

The invention provides antibacterial paint, anticorrosive paint, an antibacterial and anticorrosive coating and an oil transportation pipeline. The antibacterial and anticorrosive coating comprises a slow-release antibacterial layer and a heavy anticorrosive layer, wherein the thickness of the heavy anticorrosive layer is 50-200 micrometers, and the thickness of the slow-release antibacterial layer is 20-80 micrometers. The inner wall of the oil transportation pipeline is coated with the heavy anticorrosive layer, and the surface of the heavy anticorrosive layer is coated with the slow-release antibacterial layer. Compared with the prior art, the slow-release antibacterial and anticorrosive oil transportation pipeline has the advantages that the defects that an oil transportation pipeline on the market is poor in antibacterial effect and high in cost, and an existing oil transportation pipeline with the antibacterial effect is short in antibacterial life and poor in anticorrosive property are overcome.

Description

technical field [0001] The invention relates to an antibacterial and anticorrosion coating and an oil pipeline with the coating, which solves the problem of poor antibacterial effect of oil pipelines on the market, especially the short antibacterial life of oil pipelines caused by long-term scouring of high-temperature petroleum products during petroleum transportation. The problem belongs to the field of petrochemical and product function modification. Background technique [0002] Crude oil pipeline is an indispensable facility in the process of oil storage, transportation and processing. More than 65% of my country's crude oil production is transported by oil pipelines. Its normal operation plays an important role in the safety, stability and long-term operation of the entire petrochemical system. However, in the process of operation, it is often corroded by internal and external environmental media, which seriously threatens the safe operation of the pipeline and the qua...
