Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a rare earth complex modified styrene-butadiene rubber cable sheath material. Background technique [0002] Styrene-butadiene rubber is the most widely used synthetic rubber in the world. It is formed by random copolymerization of butadiene and styrene. Styrene-butadiene rubber has the following advantages: flat vulcanization curve, rubber material is not easy to burn and overvulcanize; wear resistance, heat resistance, oil resistance are good; the relative molecular weight is reduced to a certain level during processing and will not decrease, so it is not easy to over-vulcanize. Refining, uniform plasticity, small change in hardness of vulcanized rubber; high filling performance can be achieved by increasing the relative molecular weight, and the processing performance of oil-extended rubber is good; it is easy to be used together with other high unsaturated gener...

Problems solved by technology

However, there are unsaturated double bonds in the styrene-butadiene rubber molecule, which has poor aging effect and low strength. The cable sheath made of pure styrene-butadiene rubber has poor aging resistance and low strength, which cannot meet the requirements of the society and needs to be modified.
