Abstract

An ionic silicone gel antifouling coating, comprises an A component and a B component: The A component includes di-polyethylene glycol-terminated polydimethylsiloxane, hydroxyl-terminated polydimethylsiloxane, a pigment and a solvent. The B component includes bis[3-(triethoxysilyl)propyl]amine, zwitterionic acrylic monomer and solvent. A preparation method of the antifouling coating includes the preparation method of the A component and the B component. The preparation method of the A component is: stir and disperse the polydimethylsiloxane, the solvent and the pigment that are capped with two polyethylene glycol: The preparation method of the B component is: under the conditions of anhydrous, nitrogen atmosphere and 35 DEG C, bis[3-(triethoxysilyl)propyl]amine, zwitterionic acrylic monomer and solvent are ultrasonically dispersed.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an ionic silicone gel antifouling coating and a preparation method thereof. Background technique [0002] The bioadhesion of the hull and the surface of marine structures is a complex and dynamic process involving many factors. It is difficult for a single antifouling strategy to achieve effective and long-term antifouling effects, just like the multiple antifouling effects of marine organisms. Mechanism synergy, antifouling should also consider a variety of synergistic antifouling strategies to achieve the desired antifouling effect. [0003] In recent years, as people pay more and more attention to the protection of the marine environment, the research of non-toxic antifouling coatings has made some progress. The coatings containing non-toxic natural antifouling agents cannot be applied on a large scale due to the difficulty of obtaining natural antifouling agents. ...
