Problems solved by technology

However, aquaculture is also facing serious biofouling problems.
First, some organic matter and macromolecules are attached and adsorbed on the net cage to form an initial conditional film, and then some bacteria, fungi, and algae attach, and then some large marine plants and marine animals attach, grow, and reproduce, and finally form The complex marine fouling biome will inevitably reduce the volume of the net, reduce the permeability of the net, increase the weight of the net, lead to blockage of water flow exchange, insufficient oxygen supply, seriously affect the quality of the cultured organisms, and may even lead to the loss of the cultured organisms. death, resulting in huge economic losses

Embodiment 1

[0015] A wear-resistant and antibacterial coating for polyethylene fishing nets, which uses one or more of acrylic resin, high-chlorinated polyethylene resin, and chlorosulfonated polyethylene resin as the base material, and then adds dispersants, pigments, defoamers, and anti-foaming agents. The precipitant is obtained through dispersion and grinding, and also includes a kaolin-zinc oxide whisker-nano silver wear-resistant antibacterial agent with a mass fraction of 10%. The preparation method of the antibacterial agent is:

[0016] (1) Disperse 5 parts of zinc oxide whiskers in acetone 10 times its volume, keep the temperature at 50°C, and use ultrasonic treatment for 20 minutes, then take it out, wash it with distilled water, add it to the modification solution, supplemented by ultraviolet light Irradiation, closed reaction at 30°C and 600rpm for 3h, after the completion of filtration, and drying in a vacuum oven at 70°C to obtain modified zinc oxide whiskers, wherein the mo...

[0023] A wear-resistant and antibacterial coating for polyethylene fishing nets, which uses one or more of acrylic resin, high-chlorinated polyethylene resin, and chlorosulfonated polyethylene resin as the base material, and then adds dispersants, pigments, defoamers, and anti-foaming agents. The precipitating agent is obtained through dispersion and grinding, and also includes a kaolin-zinc oxide whisker-nano silver wear-resistant antibacterial agent with a mass fraction of 15%, and the preparation method of the antibacterial agent is:

[0024] (1) Disperse 7 parts of zinc oxide whiskers in acetone 20 times its volume, keep the temperature at 55°C, and use ultrasonic treatment for 30 minutes, then take it out, wash it with distilled water, add it to the modification solution, supplemented by ultraviolet light Irradiation, closed reaction at 40°C and 800rpm for 4 hours, after the end, filter, and dry in a vacuum oven at 80°C to obtain modified zinc oxide whiskers, wherein the m...

Embodiment 3

[0031] A wear-resistant and antibacterial coating for polyethylene fishing nets, which uses one or more of acrylic resin, high-chlorinated polyethylene resin, and chlorosulfonated polyethylene resin as the base material, and then adds dispersants, pigments, defoamers, and anti-foaming agents. The precipitant is obtained through dispersion and grinding, and also includes a kaolin-zinc oxide whisker-nano silver wear-resistant antibacterial agent with a mass fraction of 20%. The preparation method of the antibacterial agent is:

[0032] (1) Disperse 10 parts of zinc oxide whiskers in acetone 30 times its volume, keep the temperature at 60°C, and use ultrasonic treatment for 40 minutes, then take it out, wash it with distilled water, add it to the modification solution, supplemented by ultraviolet light Irradiation, closed reaction at 50°C and 1200rpm for 5h, after the completion of filtration, and drying in a vacuum oven at 90°C, modified zinc oxide whiskers were obtained, wherein...

Abstract

The invention discloses a wear-resistant antibacterial coating for a polythene fishing net. By adding kaolin-zinc oxide whiskers-nano silver wear-resistant antibacterial agent in the coating, the properties of wear resistance, aging resistance, anti-static property and antibacterial property of the coating are improved, the wear-resistant antibacterial coating is applied to the polythene fishing net, and can be adsorbed to the fishing net well, furthermore, the wear resistance and antibacterial property of the fishing net are enhanced, biofouling of the fishing net is prevented effectively, meanwhile, the service life of the fishing net is prolonged, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a wear-resistant and antibacterial coating for polyethylene fishing nets. Background technique [0002] In recent years, with the rapid growth of the world population, the aquaculture industry has also developed rapidly. However, aquaculture is also facing serious biofouling problems. First, some organic matter and macromolecules are attached and adsorbed on the net cage to form an initial conditional film, and then some bacteria, fungi, and algae attach, and then some large marine plants and marine animals attach, grow, and reproduce, and finally form The complex marine fouling biome will inevitably reduce the volume of the net, reduce the permeability of the net, increase the weight of the net, lead to blockage of water flow exchange, insufficient oxygen supply, seriously affect the quality of the cultured organisms, and may even lead to the loss of the cultured organisms. d...
