A kind of anti-fouling and anti-fatigue multi-strand monofilament mixed-twist mesh wire and preparation method thereof

Abstract

The invention relates to the field of material science. Aiming at the problems of peeling off of the mesh coating and poor fatigue resistance of mesh clothes, the invention discloses an anti-fouling and anti-fatigue multi-strand monofilament twisted mesh and a preparation method thereof. It includes nylon monofilaments, including nylon monofilaments and anti-fouling polyethylene monofilaments, the anti-fouling polyethylene monofilaments cover the nylon monofilaments with mixed twisting, and modified epoxy resin is connected between the monofilaments, Polyethylene monofilaments have a diameter of 0.2‑0.5 mm and nylon monofilaments have a diameter of 0.2‑1.2 mm. The preparation steps of twisted mesh wire include four steps: activation, dipping monofilament, mixed twisting and heating and curing. The invention prepares antifouling network cables and introduces nylon monofilaments with good mechanical properties to compound the antifouling agent into the network cables, and the obtained monofilament network cables have antifouling function, without the need for subsequent construction of antifouling coatings, and significantly improve the antifouling ability , reduce environmental pollution, and can greatly improve the anti-fouling, anti-stretch and anti-fatigue capabilities of twisted mesh cables and mesh clothing.

Description

technical field [0001] The invention belongs to the field of material science, and in particular relates to an anti-fouling and anti-fatigue multi-strand monofilament twisted network cable and a preparation method thereof. Background technique [0002] When the breeding net cage is placed in seawater for a long time, the bacterial colony will adhere to its surface. When the larvae and spores of fouling organisms approach the surface of the cage netting with the bacterial colony attached, they will adhere, secrete mucus, and accompany a series of abnormal growth, resulting in The netting material is stained by adhesion. A large number of fouling organisms will not only hinder the smooth flow of water and the exchange of water bodies, but also cause the deterioration of water quality in the tank, lack of oxygen, and affect the growth of fish. Stunting or even death seriously affects the yield and quality of seafood farming. In addition, during the breeding process, the nets ...

Problems solved by technology

[0005] The present invention aims to overcome the problems of peeling off of the mesh wire coating and poor fatigue resistance of the mesh clothing in the prior art, and provides an anti-fouling and anti-fatigue multi-strand monofilament twisted mesh wire and a preparation method thereof. Dirty network cable and nylon monofilament with good mechanical properties are introduced, and antifouling agent is compounded into the network cable. The obtained monofilament network cable has antifouling function and does not require subsequent antifouling coating construction, which can significantly improve antifouling ability and reduce environmental pollution. , to greatly improve the anti-fouling, anti-stretch and anti-fatigue capabilities of twisted mesh cables and nets
