Corrosion-resistant plastic rope and production process thereof

Abstract

The invention discloses a corrosion-resistant plastic rope and a production process thereof. The production process comprises the steps of mixing modified polyethylene, plant cellulose fibers, a plasticizer, a foaming agent, a corrosion inhibitor and a dispersing agent to obtain a blended material, putting the blended material into a film blowing machine to prepare a plastic film, cutting the plastic film into a plurality of plastic tapes, twisting the plastic tapes by a twisting machine, obtaining a plastic rope, baking the plastic rope, cooling the plastic rope to the room temperature through cold air cooling, and obtaining the anti-corrosion plastic rope. By baking the twisted plastic rope added with the plasticizer, the connection strength between plastic tapes is enhanced, gaps in the plastic rope are reduced, the compactness of the plastic rope is improved, the breaking strength of the plastic rope is improved, and alkyl active free radicals generated in oxidative degradation of modified polyethylene are captured by adding the corrosion inhibitor, so that chain reaction is inhibited to achieve the anti-corrosion effect.

Description

technical field [0001] The invention relates to the technical field of plastic ropes, in particular to a corrosion-resistant plastic rope and a production process thereof. Background technique [0002] As a common tool, rope has been widely used in many fields. With the rapid development of industry and commerce today, people have higher and higher quality requirements for rope. Plastic rope is a low-cost and easy-to-process rope. It has been favored by people in many fields; [0003] However, due to the limitation of the raw material properties of the existing plastic rope, plastic deformation will occur when the external force is applied. After the external force disappears, due to the offset of the intermolecular functional groups, it is difficult to achieve the original recovery, resulting in a decrease in the tensile strength of the plastic rope and a long service life. Shorter, and the plastic rope is prone to corrosion and aging under the influence of light, resultin...

Problems solved by technology

[0006] (1) By adding ethylene into the reactor, adding a catalyst to control the pressure and temperature reaction, adding hydroquinone as a polymerization inhibitor, and obtaining polyethylene with a low degree of polymerization, adding ethylene into the reactor, and adding cinnamic acid to the reactor to generate Reaction, intermediate E is obtained, intermediate E is added to polyethylene with a low degree of polymerization, an initiator is added, temperature and pressure are controlled, and it is soaked in a threonine solution to obtain a modified polyethylene. Benzene ring and carboxyl functional groups are introduced into the chain. The introduction of benzene ring can enhance the rigidity of the polyethylene molecular chain, thereby improving the strength and wear resistance of the modified polyethylene, and the carboxyl functional group interacts with the hydroxyl and amino groups on the threonine molecule. The threonine molecule is grafted on the polyethylene molecular chain, and various functional groups in the threonine molecule can interact with the polyethylene molecule to increase the molecular binding force, so that the intermolecular branch chains are not easy to shift, and the tensile properties are enhanced. It solves the problems of reduced tensile strength and short service life of existing plastic ropes;
