A processing method for synergistic antifouling silk containing grafted polyguanidine salt nano-copper nickel

Abstract

The invention provides a processing method for synergistic antifouling yarn containing grafted polyguanidine salt nano-copper nickel, including three processes of raw material compounding, melt spinning, stretching and heat setting. Ethylene pellets and surface-modified copper-nickel alloy nanoparticles are the main raw materials. Firstly, a composite material with synergistic antifouling effect is obtained, and then a synergistic antifouling wire is obtained after a wire drawing process. The synergistic antifouling silk performs targeted synergistic antifouling treatment on algae, barnacles and other fouling organisms in actual breeding production, preventing fouling organisms from adhering to the surface of the netting of the breeding facility, and playing a comprehensive and effective synergetic antifouling treatment. The anti-fouling effect, the sea test results show that the anti-fouling net clothing made of the anti-fouling silk can reduce the fouling biological adhesion by more than 20%, and the synergistic anti-fouling effect is very significant.

Description

technical field [0001] The invention belongs to the technical field of mariculture mesh wires, and in particular relates to a processing method for synergistic antifouling wires containing grafted polyguanidine salt nanometer copper and nickel. Background technique [0002] Seawater aquaculture facility technology has made important contributions to the supply of high-quality fish protein and the construction of blue granaries. In the technical field of seawater aquaculture facilities, seawater aquaculture facility nets (hereinafter referred to as aquaculture facility nets) will be adhered by marine fouling organisms after being placed in seawater for a period of time, thereby increasing water exchange and aquaculture inside and outside the aquaculture facility. The impact on the growth and development of fish and the production safety of breeding facilities has become a bottleneck problem restricting the development of the breeding facilities industry, seriously restricting...

Problems solved by technology

Yet this kind method can't be accepted by industry of breeding facilities at present, and this is mainly because the marine breeding environment is different from rivers and lakes with very little wind and waves. It is easy to fall off, and the netting after the paint falls off also loses its antifouling performance

[0006] In addition, the field of materials for mariculture is far from the field of fishing gear, textiles and other technical fields. The production method of wire used in the above fields is not suitable for this technical field, nor can it meet the antifouling requirements of mesh wire in this field.
