Antifouling anti-fatigue multi-strand monofilament mixed-twisted net thread and preparation method thereof

Abstract

The invention relates to the field of material science, discloses an antifouling anti-fatigue multi-strand monofilament mixed-twisted net thread and a preparation method thereof, and aims at the problem that a net thread coating can be peeled off and the anti-fatigue performance of netting is poor. The antifouling anti-fatigue multi-strand monofilament mixed-twisted net thread comprises nylon monofilaments and antifouling polyethylene monofilaments; the antifouling polyethylene monofilaments are coated with the nylon monofilaments and are mixed and twisted, modified epoxy resin is connected between the monofilaments, and the diameter of the polyethylene monofilaments is 0.2-0.5 mm, and the diameter of the nylon monofilaments is 0.2-1.2 mm. The preparation method of the mixed-twist net thread comprises the steps of activating, impregnating monofilaments, mixing and twisting, and heating for curing. According to the invention, the antifouling net thread and the nylon monofilaments with good mechanical properties are introduced, and an antifouling agent is compounded into the net thread, so that the obtained monofilament net thread has an antifouling function and does not require theconstruction of a subsequent antifouling paint, the antifouling capacity is remarkably improved, the environmental pollution is reduced, and the antifouling, anti-stretching and anti-fatigue capacities of the mixed-twisted net thread and netting can be greatly improved.

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
