Preparation method of polyethylene net thread monofilament with marine fouling prevention property

Abstract

The invention relates to the field of material science, discloses a preparation method of a polyethylene net thread monofilament with marine fouling prevention property, and aims at the problems of coating peeling and high maintenance cost in the prior art. The net thread monofilament comprises, per 100 parts by weight, 2.3-3.8 parts of copper pyrithione, 2.2-3.5 parts of pyridine bromonitrile, 2.-3.2 parts of modified nano ZnO powder, 0.8-1.2 parts of zinc acrylate resin, and the balance of a mixture of high-density polyethylene particles and polypropylene powder. The five preparation steps mainly comprise drying, uniform mixing of materials, drawing, setting and solvent removing. According to the invention, an antifouling agent is directly added into the net thread monofilament, so thatnetting has better antifouling performance; the monofilament has a certain micro-nano structure surface and good wear resistance; subsequent complicated antifouling paint construction and environmental pollution are avoided; the maintenance of net threads during use is reduced, the monofilament preparation process is simple, and the processing cost is saved.

Description

technical field [0001] The invention belongs to the field of material science, and in particular relates to a preparation method of a polyethylene network cable monofilament with anti-marine fouling properties. Background technique [0002] Aquaculture net cages have been placed in seawater for a long time. Because the net material itself is non-toxic and has a large surface area, it provides a good breeding ground for a large number of bacterial populations in seawater; Larvae and spores provide a substrate and habitat. When the larvae and spores of these fouling organisms approach the surface of the cage net that has attached to the bacterial population, they will actively attach and secrete mucus, accompanied by a series of morphological changes, predation on organic matter, and growth and reproduction, resulting in a large amount of pollution on the surface of the net material. Lesions attached. A large number of fouling organisms will not only hinder the smooth flow o...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problems of peeling off of the coating and high maintenance cost in the prior art, and to provide a preparation method of a polyethylene network cable monofilament with anti-marine fouling properties. The anti-fouling agent is compounded into the monofilament of the network cable. The network cable made of the monofilament itself has anti-fouling function, and there is no need for subsequent anti-fouling coating construction, which significantly improves the anti-fouling ability and reduces environmental pollution.
