Abstract
The invention relates to a crane cable, particularly a composition for a crane cable sheath. The thermoplastic elastomer for a crane cable sheath comprises the following components in parts by weight: 30-35 parts of PVC (polyvinyl chloride) resin, 8-10 parts of light calcium carbonate, 28-30 parts of TOTM (trioctyl trimellitate), 2-3 parts of DOS (dioctyl sebacate), 1-1.5 parts of epoxy soybean oil, 2-2.5 parts of environment-friendly calcium zinc stabilizer and 0.2-0.5 part of low-molecular polyethylene wax. The components are subjected to extrusion molding to obtain the cable sheath. The composition saves the cost, simplifies the technique, enhances the production efficiency, and satisfies the operational requirements of the customers.
Description
Technical field
The present invention relates to crane cable, relate in particular to crane cable sheath composition.
Background technology
Lifting machine requires cable to have certain tensile strength with cable, flexibility, fatigue resistance, weathering resistance, in conventional crane cable, often use neoprene rubber or chlorinatedpolyethylene rubber as the sheath of cable, rubber must have its advantage in crane cable use procedure, but also Shortcomings, neoprene or chlorinatedpolyethylene rubber must adopt large-scale Banbury mixer in mixed glue, in extrusion, must adopt continuous high temperature steam vulcanization line, the equipment of Zhe Dui company and industrial scale have proposed harsh requirement, too far behind to catch up especially to the general cable producer that does not possess this throughput.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and a kind of crane cable sheath composition for thermoplastic elastomer is provided.The present invention provides cost savings, and has simplified technique, has improved production efficiency, has met client's service requirements.
