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...
