Problems solved by technology
Most of the thermoplastic elastomers currently used are styrene-butadiene-styrene block polymers as the main raw material, but because their molecular chains contain more double bonds, they are easily degraded by oxygen and ozone aging, so they are resistant to heat and Poor environmental resistance limits its application in the wire and cable industry

Description
technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to a thermoplastic elastomer wire and cable material and a preparation method thereof. Background technique [0002] Thermoplastic elastomers are called third-generation rubbers, and are materials that combine the elasticity of rubber with the melt fluidity and reusability of thermoplastics. Due to its excellent physical and mechanical properties, electrical insulation properties and processing technology properties, it is widely used in many fields such as automobiles, electronic appliances, wires and cables, medical equipment, construction packaging, etc., gradually replacing soft plastics. Most of the thermoplastic elastomers currently used are styrene-butadiene-styrene block polymers as the main raw material, but because their molecular chains contain more double bonds, they are easily degraded by oxygen and ozone aging, so they are resistant to...
