Abstract

The invention discloses a salt-corrosion resistant plastic rope and a processing technology thereof. The rope is characterized by comprising a main rope core (1) and a plurality of subsidiary rope strands (2) which are twisted with the main rope core (2) to form a rope body, the main rope core (1) is made of Manila hemp fibers, and the subsidiary rope strands (2) are made of polypropylene fibers;the processing technology of the salt-corrosion resistant plastic rope comprises the steps of extracting the Manila hemp fibers, preparing the polypropylene fibers and preparing the rope. According tothe salt-corrosion resistant plastic rope and the processing technology thereof, the Manila hemp fibers are adopted as the raw materials of the rope core, and because Manila hemp is very tough and high in corrosion resistance to salt water, the toughness and salt-corrosion resistance of the plastic rope can be enhanced by using the Manila hemp as the rope core; the subsidiary rope strands of theplastic rope are made of the polypropylene fibers, nanometer silicon dioxide and neopentyl glycol are added in the process of preparing the polypropylene fibers to effectively improve the salt-corrosion resistance of the polypropylene fibers, and meanwhile, the polypropylene fibers have the advantages of being lightweight, high in strength, excellent in abrasion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of plastic ropes, and in particular relates to a salt corrosion-resistant plastic rope and a processing technology 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. However, when the plastic rope is transported at sea, it will inevitably encounter seawater. Seawater contains a large amount of salt, which has a corrosive effect. Plastic ropes generally corrode due to immersion in seawater, which also causes the maximum pressure that the rope can withstand to drop. , If it is not discovered in time, it will even cause harm to the goods used and threaten the life safety of users. Contents of the invention [0003] In order to solve the problem ...
