Problems solved by technology

However, this kind of material has a certain dependence on the speed of the ship. Due to the small scouring effect of seawater in static state, the update effect is poor, resulting in unsatisfactory anti-fouling effect, which cannot meet the anti-fouling of low-speed ships, submarines and offshore oil production platform facilities.

Abstract

The invention discloses a hydrolyzing-speed-controllable anti-pollution estersil material as well as a preparation method and application thereof. The preparation method comprises the following steps of: proportionally mixing an unsaturated vinyl ester monomer, unsaturated vinyl estersil and an unsaturated hydrolyzed regulated and controlled vinyl monomer, adding the mixture into a solvent under inert-gas protection, and then carrying out polymerization reaction with a free-radical initiator to generate the hydrolyzing-speed-controllable anti-pollution estersil material. In the preparation method, the hydrolyzing performance of the prepared estersil material has an adjustable characteristic to a greater degree by introducing the hydrolyzed regulated and controlled monomer, so that the dependency problem of traditional self-polishing materials on navigational speeds is solved, new surfaces can also be continuously refreshed through a hydrolytic action even though ships are stopped, and the anti-pollution requirements of low-navigational-speed ships, submarines and offshore oil-producing platform facilities can be well met; and the process is simple, the cost is lower, the hydrolyzing-speed-controllable anti-pollution estersil material is suitable for industrialized production, and the prepared estersil material has good application prospects in the field of ocean anti-pollution coatings.

Description

technical field [0001] The invention belongs to the field of material chemistry, and relates to a marine antifouling material and a preparation method thereof, in particular to a controllable hydrolysis speed antifouling silicon ester material, a preparation method and application thereof. Background technique [0002] Biofouling attached to the surface of ships and marine facilities in the ocean has caused great harm to marine transportation and the exploration, development, and utilization of marine resources. This type of fouling will significantly increase the mass of the hull, increase navigation resistance, and increase fuel consumption and greenhouse gas emissions; it will change the surface state of the hull and other marine facilities, thereby accelerating its corrosion rate; in the marine aquaculture industry, marine biofouling Also make the mesh of net cage culture be blocked, cause fish and shrimp to die in a large area. [0003] At present, the application of ...
