Cage antifouling paint for mariculture

Abstract

The invention discloses cage antifouling paint for mariculture. The paint is prepared from butyl acrylate, methyl silicone resin, gramine, rosin, nano-zinc oxide, dioctyl phthalate and an initiator. The cage antifouling paint has the advantages of low toxicity, high efficiency, strong stability, convenience in use, simple application, high cost performance, good adhesion and good antifouling performance, and accords with the environment-friendly requirement. According to the cage antifouling paint, butyl acrylate and methyl silicone resin are premixed, the mixture is modified by adopting hydroxyl silicone oil, and the mixture is mixed and ground with bentonite, so that the structure tissue performance of the paint is greatly improved, the compatibility of the paint with other ingredients can be promoted, and the service life of the paint is prolonged; and rosin and zinc oxide are premixed, the cohesion of rosin is improved, and the film forming performance of the paint is enhanced.

Description

technical field [0001] The invention relates to the field of antifouling of fishing gear, in particular to an antifouling coating for net cages used in seawater culture. 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 and many repet...

Problems solved by technology

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 and many repetitions, which easily damaged the cages and affected the breeding cycle of seafood. Therefore, there is an urgent need for an antifouling coating for deep-sea cages.
