Problems solved by technology

Since the ocean area accounts for 70.8% of the total surface area of ​​the earth, it has been found that it contains more than 80 chemical elements, and the total salt content is about 3.5%. However, the dissolved organic matter in seawater is very complex, mainly a substance called "marine humus". work, the mechanical performance is reduced, and there are operational risks

Abstract

The invention relates to a preparation method of a plastic composite material for salt-tolerant anti-corrosion macromolecular ropes. The preparation method includes: subjecting butadiene and isopreneto constant-temperature copolymerization under the action of catalysts, cooling, dropwise adding acrylonitrile and butyl acrylate to realize graft polymerization, performing reflux extraction to obtain a grafted copolymer for modification with PVC particles under the action of an initiator, blending and mixing with polypropylene fibers and an anti-corrosion agent, and finally subjecting to plasticizing, extruding, pulling and granulating through a double-screw extruder to obtain the composite material. By modified mixing and compounding of the grafted copolymer and polar amorphous high polymerPVC resin, a three-layer core-shell modifying agent is formed for improving blending interface compatibility, multi-toughening synergistic effects are achieved, easiness in double bond opening is achieved, and compatible effects are improved by further cross-linking; by blending of polypropylene fiber and the anticorrosion agent for cross-linking improvement, high adhesiveness is realized, substance stability and low permeability are improved, comprehensive salt tolerance, corrosion resistance and tensile strength can be improved, and safety in rope making operation is improved.

Description

technical field [0001] The invention relates to a preparation method of a plastic composite material for a salt-resistant and anti-corrosion polymer rope, belonging to the technical field of polymer plastic materials. Background technique [0002] With the rapid development of the shipping industry, the quality of related cables and anchor ropes has also been continuously improved, from commonly used hemp and cotton rope materials to synthetic fibers such as nylon, polypropylene, vinylon, polyester, etc., which have light specific gravity, high strength and It has good wear resistance and is widely used in 3-strand and multi-strand twisted cables. Since the ocean area accounts for 70.8% of the total surface area of ​​the earth, it has been found that it contains more than 80 chemical elements, and the total salt content is about 3.5%. However, the dissolved organic matter in seawater is very complex, mainly a substance called "marine humus". work, the mechanical performanc...
