Description
The technical field is as follows:
the invention relates to the technical field of marine antifouling paints, in particular to a broad-spectrum antifouling paint for fishing nets and a preparation method thereof, which is suitable for preventing fouling of net coats of aquaculture fishing gear such as net cages, net cages and the like.
Background art:
biofouling has had a serious impact on the marine aquaculture industry worldwide. According to literature reports, the fishing net is only soaked in seawater for 1-2 weeks, so that some fouling organisms visible to the naked eyes are attached to the fishing net, and the fouling degree changes along with the service time of the fishing net in the seawater. The attachment of fouling organisms on the net cage of the netting can bring a series of hazards, such as reduction of the net volume, reduction of the net permeability, increase of the net load, blockage of water flow, oxygen and nutrient exchange, disease nourishing, even death of the cultured organisms and the like.
Based on the above-mentioned damage caused by the attachment of fouling organisms, an effective antifouling measure is urgently needed to solve the above-mentioned problems. The current stage of antifouling measures of fishing nets mainly comprises mechanical removal, net cage design, antifouling paint use and biological competition utilization. Because both the design of the net cage and the use of biological competitive utilization have certain limitations, the mechanical cleaning and the use of antifouling paint are common measures at the present stage. Wherein the mechanical removal needs to consume a large amount of manpower and material resources and can bring certain influence on the cultured organisms. Therefore, the application of the antifouling paint is an important means for realizing the biological adhesion prevention of the fishing net at the present stage.
The marine organisms capable of attaching to the fishing net are numerous and mainly comprise common mussels, oysters, barnacles, large-chambered-membrane bugs, ascidians, glass ascidians, marine algae, bryozoans and the like. Although the field of antifouling of fishing nets has been researched and applied correspondingly, the antifouling performance of the antifouling paint of fishing nets is single, and the antifouling paint of fishing nets can not effectively control the attachment of a plurality of attached organisms on the fishing nets. Therefore, it is necessary to develop a broad-spectrum antifouling paint for fishing nets.
The invention content is as follows:
the invention aims to overcome the defects of the prior art and provide a broad-spectrum antifouling paint for fishing nets.
The invention also aims to provide a preparation method of the broad-spectrum fishing net antifouling paint.
The invention mainly solves the problems that the existing antifouling paint for fishing nets has single antifouling performance and can not effectively control the attachment of numerous attached organisms on the fishing nets, and the like.
The technical scheme of the invention is as follows: the broad-spectrum antifouling paint for fishing nets is characterized by being prepared by mixing the following raw materials in parts by weight:
5-30 parts of matrix resin, 6-20 parts of rosin, 2-5 parts of plasticizer, 5-20 parts of composite antifouling agent, 3-10 parts of anti-settling agent and 25-45 parts of solvent.
Further, the matrix resin is one or a mixture of more of epichlorohydrin resin, acrylic resin, chlorinated rubber, epoxy resin, chlorosulfonated polyethylene and polyurethane resin.
Further, the plasticizer is one of tricresyl phosphate, dibutyl phthalate and chlorinated paraffin.
