Problems solved by technology

Aramid fiber is currently the strongest non-metallic reinforcement. There is no domestic supplier that can produce high-performance aramid yarn. Optical cable manufacturers must rely on imports. The high price restricts the large-scale production of aramid fiber used in optical cables.

Abstract

A basalt fiber enhanced belt is prepared by painting coating slurry on woven basalt fibers, which have been painted by the coating slurry. The coating slurry consists of the following components in parts by weight: 85 to 90 parts of water, 2 to 3 parts of E type epoxy resin, 1 to 2 parts of poly(glycol adipate) based polyurethane, 0.5 to 1.5 parts of polyvinyl acetate, 2 to 4 parts of nano SiO2, 1 to 3 parts of nano calcium silicate, 0.2 to 0.5 part of fatty acid amine acetate, 0.1 to 0.3 part of polyoxyethylene stearate, 0.2 to 0.3 part of ethoxyamine, 0.1 to 0.2 part of quaternary ammonium salt, and 0.2 to 0.7 part of silane coupling agent KH550. The basalt fiber enhanced belt has the advantages of high tensile strength, high elasticity modulus, good flexibility, wear resistance, bending resistance, high temperature resistance, and user friendliness.

Description

technical field [0001] The invention relates to a basalt fiber reinforced belt and a preparation method thereof, and relates to the technical field of optical fiber and cable. Background technique [0002] With the development of power transmission systems, the optical fiber and cable industry has grown rapidly, and the non-metallic reinforcement materials for optical cables are mainly glass fibers and aramid fibers. Glass fiber can meet the requirements of conventional optical cable applications, but it has great limitations in terms of strength, moisture absorption, creep resistance, and chemical stability. Aramid is currently the strongest non-metallic reinforcement. There is no domestic supplier that can produce high-performance aramid yarn. Optical cable manufacturers must rely on imports. The high price restricts the large-scale production of aramid for optical cables. Therefore, the current situation makes the market urgently need a high-quality and low-cost reinforc...
