Abstract

The invention relates to the field of paint and discloses a copper-bearing linear self-polishing marine anti-fouling paint. The paint of the invention contains eight different types of linear self-polishing anti-fouling resins. The synthetic process route of the resins is easier to control and the cost is lower. The resins have stable molecular weight and narrower molecular weight distribution, and have good linear polishing ability. After the resins are used to prepare the copper-bearing marine anti-fouling paint, antibacterial property, antifouling property, adhesion and weatherability are excellent. The paint of the invention is applicable to a long-acting antifouling coating system of ships.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a copper-containing linear self-polishing marine antifouling coating. Background technique [0002] In the course of the development of marine economy and shipping industry, the problem of marine fouling and adhesion continues to plague people. Marine fouling will not only increase the resistance of ships sailing and fuel consumption, accelerate the corrosion and degradation of hull materials, but also destroy the ecological balance of waters. The British International Paint Company has made statistics on the increase of ship bottom fouling and fuel consumption: if the ship bottom is fouled by 5%, the fuel consumption will increase by 10%; if the ship bottom fouling is greater than 50%, the fuel consumption will increase by more than 40%. [0003] Self-polishing paint is a kind of antifouling paint for ships, and its coating film can be self-polishing after being washed by sea water. Th...
