Abstract

The invention discloses a fiber rope with the surface coated with a polymer and a preparation method of the fiber rope. The fiber rope with the surface coated with the polymer comprises a polymer coating layer and a fiber rope core layer, wherein an outer wall of the fiber rope core layer is coated with the polymer coating layer. The preparation method comprises the following steps that a thermoplastic polymer and an additive are weighed at a mass ratio, mixed uniformly and put into a single screw extruder for mixing and melting; a fiber rope penetrates through a mould, and is coated with the molten polymer uniformly; and a cold water tank is introduced rapidly for cooling and shaping. According to the fiber rope and the preparation method, the strength and the usability of a fiber are improved; the fiber can be bonded with various resin for preparing a composite; the fiber rope has a wide application space in the fields of optical cables, electric cables, fishing nets, net cages, protecting nets, reinforcing wires, complex fibers and the like; the fishing net woven by the fiber rope can meet a requirement of high tenacity; the fiber rope is smooth in surface, so that an attachment space of parasites is reduced; and the fishing net is easy to clean, convenient, long-lasting and durable.

Description

[0001] technical field [0002] The invention relates to a fiber application modification technology, in particular to a surface-coated polymer fiber rope and a preparation method thereof. technical background [0003] Ultra-high molecular weight polyethylene fiber, also known as high-strength high-modulus polyethylene fiber, high-orientation polyethylene fiber, high-performance polyethylene fiber. UHMWPE fiber has high strength, high modulus and high degree of orientation, and is widely used in the manufacture of bulletproof protective equipment, ropes, cables, fishing nets, and sports equipment. UHMWPE fibers are the commercialized high-performance fibers with the highest specific strength available today. However, due to the low monofilament fineness of the fiber during use, the wear resistance of a single fiber has become a short board for fiber applications, and its poor bundling also seriously affects its scope of use. [0004] The Chinese patent "Metal-coated polyme...
