Problems solved by technology

Under the action of huge tension, the sand is like a sharp blade, causing wear and damage to the rope, seriously affecting its service life
Moreover, because the rope has been soaked in seawater for a long time, inorganic salts are easy to adhere to the surface. During the use of the rope, along with picking up and drying, these inorganic salt particles crystallize, which will corrode the rope and reduce its life.

Embodiment 1

[0025] Using the method described in the present invention to make a marine rope with a specification of 100mm, it is specifically realized through the following steps:

[0026] 1) Twist 240 bundles of 1500D HMPE fibers into twisted yarns, and at the same time perform the first-level coating treatment. The twist is weak twist, and the twist direction is divided into S and Z directions. The solid content of the coating glue solution is 4%. The drying temperature is 40°C, and the drying time is 10 minutes;

[0027] 2) According to the different twist directions of the strands, weave the strands in a specific way, the number of spindles is 12, and the pitch is between 300mm-320mm;

[0028] 3) Carry out the second-level tensioned water-based amino resin coating on the braided sub-rope, the solid content of the coating glue solution is 15%, the oven temperature is 60°C, and the drying time is 30 minutes. After two-stage coating treatment, the sub-rope The final glue rate of the ro...

Embodiment 2

[0032] Using the method described in the present invention to make a marine rope with a specification of 140mm, it is specifically realized through the following steps:

[0033] 1) Twist 350 bundles of 1500D HMPE fibers into twisted yarns, and at the same time carry out the first-level coating treatment. The twist is weak twist and the twist direction is divided into S direction and Z direction. The drying temperature is 60°C, and the drying time is 15 minutes;

[0034] 2) According to the different twist directions of the rope strands, weave the rope strands in a specific way, the number of spindles is 8 spindles, and the pitch is between 300mm-320mm;

[0035] 3) Apply the second level of tensioned water-based amino resin coating to the braided sub-rope. The solid content of the coating glue solution is 7%, the oven temperature is 40°C, and the drying time is 20 minutes. After two-level coating treatment, the sub-rope The final adhesive rate of the rope is 15%, and the diame...

Embodiment 3

[0039] Using the method described in the present invention to make a marine rope with a specification of 100mm, it is specifically realized through the following steps:

[0040] 1) Twist 120 bundles of 1500D HMPE fibers into twisted yarns, and at the same time carry out the first-level coating treatment. The twist is weak twist and the twist direction is divided into S direction and Z direction. The drying temperature is 50°C, and the drying time is 12 minutes;

[0041] 2) According to the different twisting directions of the strands, weave the strands in a specific way, the number of spindles is 12, and the pitch is between 220mm-240mm;

[0042] 3) Carry out the second-level tensioned water-based amino resin coating on the braided sub-rope. The solid content of the coating glue solution is 10%, the oven temperature is 50°C, and the drying time is 20 minutes. After two-stage coating treatment, the sub-rope The final adhesive rate of the rope is 18%, and the diameter of the su...

Abstract

The invention discloses a three-layer composite marine rope and a manufacturing method thereof, relating to the field of ropes, comprising a main rope (1), a sand-proof protective layer (2) and a wear-resistant layer (3). The main rope (1) It is set that several ultra-high molecular weight polyethylene fiber sub-ropes (11) are braided in parallel, and the sand-proof protective layer (2) is set to be covered with non-woven fabric on the main rope (1), and the wear-resistant protective layer (3) It is set as a sheath made of polyester fiber, covering the outside of the sand control protective layer (3). The invention has the advantages of simple manufacturing process, convenient operation, high strength, low elongation, corrosion resistance and long service life of the rope.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a three-layer composite marine rope and a manufacturing method thereof. Background technique [0002] The existing marine ropes are basically composed of a rope core and a rope sheath. The rope core is twisted or braided by a multi-strand fiber rope, and the rope sheath is braided by a multi-strand fiber to form a coating layer. Due to the defects of the braided structure itself, the strength loss of the rope and the elongation of the rope are relatively large. Ultra-high molecular weight polyethylene fiber has high strength, lower density than water, lower elongation at break, and corrosion resistance, which has obvious advantages in marine ropes. During the use of marine ropes, it is easy for sand particles in seawater to enter the interior of the rope. Under the action of huge tension, the sand is like a sharp blade, causing wear and damage to the rope, seriously affecting its service l...
