Problems solved by technology

[0008] The service life of the spiral cable processed by this method is relatively short, and the rebound performance is poor. Usually, after being stretched 500 times, the proper rebound performance of the spiral cable is lost, and the cable is completely straightened; in addition, the PVC material In the process of production and use, polybrominated biphenyls and polybrominated diphenyl ethers will be produced, which will pollute the environment

Abstract

The invention provides a method for processing a novel environmental-protection spiral cable with high elasticity, which comprises the following steps of: 1, using a copper wire conductor to twist to make the internal core of the cable; 2, using TPU as raw material to process the cable; 3, rolling the cable wire with a reeling rod; 4, forming the reeled cable wire into a spiral cable by using a high temperature oven, wherein the temperature of the oven is 145 DEG C and the time is 20 minutes; and 5, cooling the formed spiral cable with cooling water to prepare the novel environmental-friendly spiral cable. The invention improves the temperature resistance and resillence of the product via improvement of the process.

Description

technical field [0001] The invention relates to a cable, in particular to a spiral cable and a processing method thereof, belonging to the technical field of cable processing. Background technique [0002] Spiral cable is a kind of equipment connection line that uses scalability to work. It is mainly used to control the electrical connection of the movement of movable equipment. It can rebound quickly in a short time. It is widely used in mobile equipment such as automobiles, machines, and instruments. . The spiral cable in the prior art includes a wire core and a sheath, and the sheath covers the outer periphery of the wire core. [0003] The processing method of traditional spiral cables usually uses oxide as a thermal initiator to add polyethylene, polyethylene is extruded onto the wire core at a low temperature at the decomposition temperature of the oxide, and then heated to a temperature above the decomposition temperature of polyethylene to form a cross-linking react...
