A preparation method of polyethylene network cable monofilament with anti-marine fouling properties

Abstract

The invention relates to the field of material science, and discloses a preparation method of polyethylene mesh wire monofilament with anti-marine fouling properties, aiming at the problems of peeling off and high maintenance cost of the prior art coating. Each 100 parts by mass of the monofilament mesh wire contains the following substances: 2.3-3.8 parts of copper pyrithione, 2.2-3.5 parts of pyridine bromonitrile, 2.8-3.2 parts of modified nano-ZnO powder, 0.8-1.2 parts of zinc acrylate resin, the rest The parts by mass are the mixture of high-density polyethylene particles and polypropylene powder. The five preparation steps mainly include: drying, material mixing, wire drawing, shaping and solvent removal. In the invention, the antifouling agent is directly added to the mesh wire monofilament, so that the mesh clothing has better antifouling performance; the monofilament has a certain micro-nano structure surface and good wear resistance; and the subsequent cumbersome construction of antifouling paint and other complications are avoided. Pollution to the environment; reduce the maintenance work of the network cable during use, 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.
