Problems solved by technology

Tracing it to its cause, one is that these fishing net anti-algae (anti-fouling) agents are mostly "open" preparations that can be dissolved in water, causing pollution to waters; the second is that the anti-algae (anti-fouling) effect is not ideal, and the persistence is poor; The antibiotic spectrum is not wide, and the growth of all attached organisms cannot be inhibited; the fourth is that the film-forming performance is poor, the product is easy to stick, and the quality is not good; the fifth is that the price is high, and it is not easy to popularize and apply

Abstract

The invention relates to an anti-algae agent of fishing net mainly prepared with 5 to 15 weight portion of tetrachlorophthalic, 2 to 10pbw of pyrithione, 2 to 10pbw of Mthylene Bis (thiocyanate), 30-70pbw of acrylic resin and 0.1 to 0.5pbw of polyacrylate. The anti-algae agent of the fishing net is an 'enclosed type' preparation that is dissolvable in water. The anti-algae agent has the advantages of good anti-algae (anti-fouling) effect, water-resistance and wear resistance, wide antibiosis spectrum, safe and convenient using and no pollution. The culture period is shortened when the anti-algae agent is applied to the fishing net (the harvest of scallop can be advanced for 1 to 2 months), and the yielding of aquatic products increases over 15 percent.

Description

technical field [0001] The invention relates to a chemical composition, in particular to an anti-algae agent for fishing nets and a preparation method thereof. Background technique [0002] my country's aquaculture industry is developing rapidly, in which a large number of fishing nets are used. Fishing nets are usually woven from wires made of polyethylene, polyvinyl chloride, polypropylene or nylon. According to the different breeding objects, the net wires are thick or thin, and the mesh holes are large or small, so as to be processed into various specifications of net cages, net boxes, net fences and fishing nets and other fishing nets and nets. Because the fishing net is soaked in water for a long time, it is extremely vulnerable to the erosion of algae, moss, fungus, barnacles, dragon fruit, mussels, oysters and amphipods, thereby shortening its service life. In order to solve this problem, it is necessary to organize manpower to clean and decontaminate the net frequ...
