Abstract

The invention provides an aqueous fishing net antifouling paint and a preparation method thereof. The antifouling paint comprises a film-forming resin, an antifouling filling material, a defoaming agent, a dispersing agent, an anti-sedimentation agent and water. The preparation method comprises the following steps: weighing various components in a proportion; preparing an aqueous solution from the defoaming agent, the dispersing agent and the anti-sedimentation agent; mixing and grinding the antifouling filling material which is subjected to pretreatment together with a dispersing agent solution with the anti-sedimentation solution and partial defoaming agent solution, standing for 12 hours, and then adding the rest defoaming agent solution and evenly mixing; and finally, adding water to regulate viscosity. The aqueous fishing net antifouling paint provided by the invention has the advantages of low toxicity, high efficiency, strong stability, adjustable color, high cost performance, good adhesion and good antifouling property and is convenient to use, and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of antifouling coatings, in particular to a water-based antifouling coating for fishing nets and a preparation method thereof. Background technique [0002] The marine environment is a highly corrosive and biofouling environment. After the ship is attached to organisms, it will obviously increase the surface navigation friction resistance, reduce the speed of the ship, increase fuel consumption, and increase the number of docking maintenance. However, when the deep-sea cages used for breeding are attached by a large number of marine organisms, the mesh holes will be blocked, affecting the convection of seawater inside and outside the cages, reducing the content of dissolved oxygen and food supply, resulting in poor growth and even death of the cultured seafood. Seriously affect the yield and quality of seafood farming. Previously, manual or mechanical beating was used to remove marine organisms with a large workload...
