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 1500DHMPE 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 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 rope is 20%, and the diameter of the sub-rope ...

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:

Abstract

The invention discloses a three-layer composite marine rope and a manufacture method thereof, and relates to the field of ropes. The three-layer composite marine rope comprises a main rope (1), a sand prevention protection layer (2) and a wear-resistant layer (3), wherein the main rope (1) is formed by knitting a plurality of ultra-high molecular weight polyethylene fiber sub ropes (11) in parallel; the sand prevention protection layer (2) is a piece of non-woven fabric and wrapped on the main rope (1); the wear-resistant protection layer (3) is arranged to be a protection cover formed by knitting polyester fibers and wrapped at the external part of the sand prevention protection layer (2). The three-layer composite marine rope is simple in manufacture process, convenient to operate, high in strength, low in elongation, corrosion-resistant and long in service life.

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...
