Description

Antifouling material and preparation method thereof

Technical Field

The invention belongs to the technical field of industrial coating, and particularly relates to an antifouling material and a preparation method thereof.

Background

At present, the industrial coating field does not have marine organism prevention coating and antifouling coating in the true sense. The installation of the water supply and drainage pipeline in the early stage of China is not critical based on domestic basic materials, the technical conditions are poor, and the branch line layout of the water supply galvanized metal pipe and the water drainage ceramic tile pipeline is basically adopted. Until the late 80 s and early 90 s in the last century, plastic-aluminum rubber section pipes are changed, but main water conveying main lines still adopt metal pipelines such as carbon steel and the like. The drainage system adopts a prefabricated cement pipe or a plastic pipeline. The material can not solve the problem that biological shells or algae are adsorbed on the wall of the pipeline, and the water pipe is blocked because the biological shells or algae cannot be cleaned more and more thickly all the year round, and the problem of water quality safety is still not solved. The economic loss caused by old and new removal can not be counted every year in China, the urban drainage function is reduced due to rapid growth of population and continuous expansion of urbanization, and the urban inland inundation caused by unsmooth drainage generated by rainstorm at each seam can not be estimated. In the aspect of coating ship waterline, the biological shells or algae are adsorbed and accumulated to cause serious influence on sailing. Thus, the technical problems are not easy to solve.
