[0071] A preparation method for long-acting self-polishing antifouling coating, comprising the following steps:
[0072] 1) Proportion components according to mass percentage:
[0073] Self-polishing resin 50%;
[0074] Cuprous oxide 20%;
[0075] Nano silver 0.02%;
[0076] Capsaicin 0.1%;
[0077] Additives and pigments and fillers 12.5% (additives 5%, pigments and fillers 7.5%);
[0078] Solvent 17.38%.
[0079] Wherein, the additives are defoamers, dispersants, and wetting agents; the pigments and fillers are alumina, iron red, and titanium dioxide; the solvents are xylene and toluene (the ratio is 1:4).
[0080] 2) Preparation: Mix the liquid components in the components evenly, then add the solid components, add to the vacuum mixer and stir, stir evenly, grind on the grinder, when the particle size of the solid particles is less than 25 microns, pack it .
[0081] After testing, the coating adhesion of the coating in this embodiment is grade 1, the antifouling t...
