Problems solved by technology

[0003] Purpose of the invention: The purpose of the invention is to solve the problem that the existing cable sheath has good mechanical properties at room temperature, but when the temperature is low, the mechanical properties become poor and the cold resistance is not good. After long-term storage, it will slowly harden, lose adhesion, and flow Poor, poor bonding performance

The cable sheath prepared by the components and the preparation process provided by the invention has a tensile strength of greater than 12Mpa and an elongation at break of greater than 350%, the ageing performance and the wear resistance of the sheath are improved, a good weather resistance is achieved, and the volume resistivity of the material is also improved.

Description

technical field [0001] The invention relates to a cable sheath and a preparation process thereof, in particular to a component of a stretch-resistant insulating cable sheath and a preparation process thereof. Background technique [0002] At present, the main material commonly used in China as the cable sheath is neoprene. Neoprene has good flame retardancy and good mechanical properties at room temperature, but when the temperature is low, the mechanical properties deteriorate and the cold resistance is not good. Afterwards, it will slowly harden, lose adhesion, have poor fluidity, and poor bonding performance. The price of neoprene is relatively high. If it is used alone as the main material of the cable sheath, the cost is relatively expensive. Chlorinated polyethylene compound is a kind of saturated chlorine-containing rubber, which partially retains the properties of polyethylene, and its elasticity and thermal stability decrease, and the substance becomes a semi-rigid ...
