A kind of low temperature resistant special cable sheath material and preparation method thereof.It is compound as basis material using polyether-ether-ketone, polyethylene and polyimides, and it is modified to introduce super branched polyurethane modified ground polymers progress resistance to low temperature, using cumyl peroxide as crosslinking catalyst, using silicon nitride crystal whisker as reinforcing agent, composite material is formed by melt blending, on the basis of the sheath material ensure that original mechanical strength does not reduce, improves the durability and reliability of special cable, especially special cable and improve cold-resistant resistance to low temperature. |
