Waterborne self-polishing antifouling paint for fishing and preparation method thereof

Abstract

The invention discloses a waterborne self-polishing antifouling paint for fishing and a preparation method thereof. The preparation method comprises the following steps: treating garlic, potatoes, asbestos powder and mica powder to obtain capsaicin-modified inorganic powder; then polymerizing the capsaicin-modified inorganic powder with synthesized zinc acrylate and acrylic acid to obtain an antifouling paint; after a coating is formed, hydrolyzing zinc polyacrylate on a polymer molecule main chain on the coating surface to release zinc acrylate. Meanwhile, the hydrolyzed polymer molecular main chain also contains a capsaicin functional group with antifouling activity, and the hydrolyzed polymer molecules keep the performance of inhibiting attachment of marine organisms, so that the paintcan effectively prevent the attachment of the marine organisms to the surfaces of fishing nets, ships and vessels, coastal facilities and the like and has good antifouling performance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based self-polishing fish antifouling coating and a preparation method thereof. Background technique [0002] With the ever-increasing human demand for seafood, as well as overfishing of marine organisms, coupled with man-made marine pollution, the global cage aquaculture industry has flourished. Because marine organisms are easy to attach to the net surface of the net cage and net gear, it will block the mesh, affect the convection of seawater inside and outside the net cage, reduce the content of dissolved oxygen and food supply, and cause stunted or even death of the cultured seafood. Seriously affected the output and quality of seafood farming. In the past, manual or mechanical beating was used to remove marine organisms, which required a lot of work, many repetitions, easy damage to the cages, and also affected the breeding cycle of seafood. Therefore, ...

Problems solved by technology

Because marine organisms are easy to attach to the net surface of the net cage and net gear, it will block the mesh, affect the convection of seawater inside and outside the net cage, reduce the content of dissolved oxygen and food supply, and cause stunted or even death of the cultured seafood. Seriously affected the yield and quality of seafood farming

In the past, manual or mechanical beating was used to remove marine organisms with a large workload, many repetitions, and the cages were easily damaged, which also affected the breeding cycle of seafood. Therefore, there is an urgent need for an antifouling coating for cages

Antifouling coatings containing organic tin net cages have been completely banned due to environmental protection regulations, and aquaculture owners are still in a dilemma of "raising fish for three days and drying nets for two days", which has seriously affected the development of the aquaculture industry
