Abstract

The invention belongs to the technical field of marine protection, and in particular relates to a water-based soft biomass antifouling paint and a preparation method thereof. A water-based soft bio-antifouling paint, the paint comprises A, B two-component, A, B component mass ratio is 8-10:1, wherein A component is the resin base material carrier, the mass fraction ratio is : Water-based acrylic resin 60-66%, red iron oxide 0-6%, zinc oxide 5%, active silica 0-3%, organic bentonite 0-1%, zinc pyrithione 3-4%, pyrithione Copper 3-4%, antifouling agent 9-10%, ethanol 5%, water 6%; B component is a crosslinking agent. The formula adopted in the invention is nontoxic and harmless, and the antifouling paint obtained after mixing has good antifouling effect.

Description

technical field [0001] The invention belongs to the technical field of marine protection, and in particular relates to a water-based soft biomass antifouling paint and a preparation method thereof. Background technique [0002] It is well known that the most effective and economical way to deal with marine biofouling is to use antifouling coatings. The development of antifouling coatings has gone through several generations, and a complete set of coating resin preparation technology represented by self-polishing type and low surface energy type has been formed, which greatly promotes the development of marine coatings. Although the existing various antifouling coatings have good antifouling properties, most of them are toxic and harmful, and have high VOC emissions, which is not conducive to environmental protection. Contents of the invention [0003] The invention provides a water-based soft biomass antifouling paint which not only meets the requirement of environmental ...
