Processing method of nanometer copper and nickel synergetic antifouling wires containing grafted polyguanidine salt

Abstract

The invention provides a processing method of nanometer copper and nickel synergetic antifouling wires containing grafted polyguanidine salt. The method includes the three processes of raw materials compounding, melt-spinning, and stretching and heat forming. With HDPE particles, grafted polyguanidine salt / polyethylene particles and surface modified copper nickel alloy nanoparticles as a main rawmaterial, firstly, a composite material with the synergetic antifouling effect is obtained, and then the synergetic antifouling wires are obtained after a wire drawing technology. The synergetic antifouling wires carry out targeting synergetic antifouling treatment on algae, barnacle and other fouling organisms in the practical breeding production, the fouling organisms are prevented from attaching to the surface of culture and proliferation facility net clothing, the comprehensive and effective synergetic antifouling action can be achieved, the results of sea tests show that the attachment ofthe fouling organisms of the culture and proliferation facility net clothing made of the antifouling wires can be lowered by more than 20%, and the synergetic antifouling effect is very significant.

Description

technical field [0001] The invention belongs to the technical field of mariculture mesh wire, and in particular relates to a processing method for synergistic anti-fouling wire containing grafted polyguanidine salt nano-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 the g...

AI Technical Summary

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 mariculture materials is far from the field of fishing gear, textiles and other technical fields. The silk production methods in the above fields are not suitable for this technical field, nor can they meet the antifouling requirements of mesh wires in this field.
