Environment-friendly fishing net protective glue and protective coating and dip coating method of protective coating

Abstract

The invention discloses environment-friendly fishing net protective glue. The environment-friendly fishing net protective glue is prepared from components in percentage by weight as follows: 5%-40% ofresin, 10%-40% of an anti-fouling agent, 5%-28% of a modified sterilizing agent, 0.5%-3% of pigments and fillers, 1%-9% of an anti-settling agent and 5%-30% of a solvent. The invention further discloses an environment-friendly fishing net protective coating and a preparation method thereof. A fishing net dip-coated with the coating can realize anti-fouling clearing of marine organisms and foulingorganisms, the thickness of the coating can reach 12-30 mu m, so that the weight of the fishing net dip-coated with the coating is slightly increased, overload work of the fishing net is avoided, andthe service life of the fishing net is prolonged; the coating accords with the principle of thermal expansion and contraction of the fishing net; the environment-friendly fishing net protective coating uses a simple dip-coating method, is low in cost and easy to popularize and use among ordinary fishermen and has good social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to an environment-friendly protective glue for fishing nets, a protective coating and a dip coating method thereof. Background technique [0002] With the improvement of people's quality of life, the demand for seafood is increasing year by year, and after long-term seafood fishing, the supply of seafood has been seriously insufficient, which has promoted the development of the marine aquaculture industry. At present, the marine aquaculture industry is mainly offshore , ocean farming is also booming, and with the development of this industry, the problem of anti-fouling of fishing nets used in the farming industry has become increasingly prominent and intensified, mainly because the marine environment is a corrosive and biofouling environment, and the protection of fishing nets and fishing gear The depth of immersion in the sea generally ranges from 0-20m, which happens to be the a...

[0002] With the improvement of people's quality of life, the demand for seafood is increasing year by year, and after long-term seafood fishing, the supply of seafood has been seriously insufficient, which has promoted the development of the marine aquaculture industry. At present, the marine aquaculture industry is mainly offshore , ocean farming is also booming, and with the development of this industry, the problem of anti-fouling of fishing nets used in the farming industry has become increasingly prominent and intensified, mainly because the marine environment is a corrosive and biofouling environment, and the protection of fishing nets and fishing gear The depth of immersion in the sea generally ranges from 0-20m, which happens to be the area where marine organisms grow most vigorously, and it is easy to breed marine organisms, marine algae, bryozoans, etc. When the fishing net is attached by a large number of marine organisms, the weight of the fishing net will increase several times times, the fishing net is overloaded, which greatly shortens its service life, and the activities of the fouling organisms themselves also have an erosion and damage effect on the fishing net, blocking the mesh, affecting the seawater convection inside and outside the net cage, reducing food supply, and at the same time, the water quality in the fishing net is reduced, which increases The probability of aquaculture products being infected with parasites and various diseases will lead to the yield and quality of aquaculture. For the marine aquaculture industry, antifouling of fishing nets has become a key issue
