Abstract
The invention discloses a method for preparing antifouling and anticorrosion coating with added hydrophobic modified cuprous oxide for fishing nets. The method includes adding graphene dispersion liquid and carbon nano-tubes oxidized and modified by mixed acid into waterborne epoxy resin and uniformly stirring the graphene dispersion liquid, the carbon nano-tubes and the waterborne epoxy resin; adding curing agents into the waterborne epoxy resin, stirring the curing agents until the resin and the curing agents are completely mixed with one another to obtain mixtures; adding the mixtures, chlorosulfonated polyethylene resin, rosin, plasticizers, irradiation-modified aluminium triphosphate and the modified cuprous oxide into iron buckets with sealing covers; sealing the iron buckets, and then carrying out quick dispersion and oscillation; filtering and separately packaging the coating. The method has the advantages that irradiation modification is carried out on aluminium triphosphate by the aid of gamma rays, accordingly, the corrosion inhibition performance of the aluminium triphosphate modified by high irradiation dose can be obviously improved, the aluminium triphosphate with the high irradiation dose is used as a filler for preparing the antifouling and anticorrosion coating, and the antifouling and anticorrosion coating is excellent in long-term anticorrosion property; graphene is excellent in waterproof performance, accordingly, the impedance module value of the epoxy resin can be increased, and the corrosion resistance of coatings can be improved.
Description
technical field [0001] The invention belongs to the field of anti-fouling and anti-corrosion fishing nets, and in particular relates to a method for preparing anti-fouling and anti-corrosion coatings for fishing nets by adding hydrophobically modified cuprous oxide. Background technique [0002] Like other marine facilities, the aquaculture industry faces the same severe biofouling problem. Fouling organisms not only cause serious harm to cultured organisms, but also greatly shorten the service life of fishing equipment such as nets and cages, resulting in huge economic losses. There are three main antifouling measures for the fouling problem in the aquaculture industry, physical removal, biological methods and chemical antifouling coatings. Among them, manual or physical mechanical removal is time-consuming and laborious, and biological control methods that use competition among organisms to achieve antifouling purposes are only suitable for a small number of specific orga...
