Super-wear-resistant and high-elasticity vulcanized polyurethane cable sheath material and preparation method thereof

Abstract

The invention discloses a super-wear-resistant and high-elasticity vulcanized polyurethane cable sheath material. Raw materials involved in preparation of effective components comprise polyether typepolyurethane rubber, polyester type polyurethane rubber, an anti-aging agent MB, a flow dispersion auxiliary agent, ozone protection wax, sulfur, stearic acid, BIBP, a crosslinking auxiliary agent, aflame retardant, white carbon black, a coupling agent A172, titanium dioxide, temperature-resistant scarlet, an ultraviolet absorbent and an anti-hydrolysis agent. The cable sheath has excellent mechanical properties and wear resistance, the service life of a cable can be greatly prolonged, the enterprise brand effect is improved, and better economic benefits are brought to customers. Meanwhile, pollution emission of a cable manufacturing enterprise can be reduced due to the longer service life, and the requirements for energy conservation and environmental protection are met.

Description

technical field [0001] The invention relates to the cable industry, in particular to a cable sheath material that requires ultra-high wear resistance, strength and tear resistance, and at the same time has higher elasticity and softer hand feeling than thermoplastic polyurethane (TPU) Rubber-type polyurethane material with better wrapping properties. In particular, it relates to a super wear-resistant and highly elastic vulcanized polyurethane cable sheath material and a preparation method thereof. Background technique [0002] At present, some mobile cable fields, including port machinery, mining, shield tunneling and other fields, require the cable to have good flexibility, and at the same time require the sheath to have excellent wear resistance to prevent damage from being pierced or smashed by ore. Because the cable is not soft enough, it is inconvenient to use, and the cable core is prone to broken cores. In order to make the cable soft, ordinary rubber sheaths will b...

AI Technical Summary

Problems solved by technology

Because the cable is not soft enough, it is inconvenient to use, and the cable core is prone to broken cores. In order to make the cable soft, ordinary rubber sheaths will be used, and the cable sheath will not be wear-resistant enough. It will not take long because the sheath is damaged. cause the cable to be scrapped

[0003] At present, it is difficult to achieve a good balance between the above two situations. Usually, the solution of the domestic and international cable industry is to use thermoplastic polyurethane (TPU) as the sheath material of the mobile cable. TPU has excellent comprehensive performance, wear resistance, strength and Tear resistance is better than ordinary rubber materials, but its biggest problem is that it is a plastic material after all, its elasticity cannot be compared with rubber materials, and it feels like plastic. During the long-term use of the cable, it is prone to insufficient sheath wrapping force The cable core is loose and broken, which affects the normal operation of the equipment
