High temperature resistant anti-tearing silicone rubber flexible cable and preparation method thereof

Abstract

The invention discloses a high temperature resistant anti-tearing silicone rubber flexible cable and a preparation method thereof. The cable comprises a cable core and a restrictive coating sequentially arranged from interior to exterior. A knitting layer is arranged outside the restrictive coating. The cable core is formed by stranding a plurality of core bodies at a time. Gaps in the cable core are filled with glassfiber cords. The longitudinal stretching strength of the glassfiber cords is larger than 5000 Mpa, and the stretching modulus is larger than 90 Gpa. Compared with the prior art, the cable has the advantages of resisting high temperature and friction, being good in flexibility and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a high-temperature-resistant and tear-resistant silicone rubber flexible cable and a preparation method thereof. Background technique [0002] At present, the silicone rubber cables on the market are generally silicone rubber insulation + silicone rubber sheath, the material is ordinary silicone rubber, and the structure adopts the conventional structure of core wire + sheath, which is used for industrial automation, electromechanical complete sets of equipment, machine tools with temperature resistance requirements Electrical connections in control systems such as mechanical equipment, logistics transmission systems, production lines, etc. [0003] At present, the ordinary silicone rubber cables on the market are generally made of ordinary silicone rubber for the insulating sheath, which has poor tear resistance and wear resistance. Cables have problems such as poor acid and alkali resist...

AI Technical Summary

Problems solved by technology

[0003] Common silicone rubber cables currently on the market, the insulation sheath material is generally ordinary silicone rubber, this material has poor tear resistance and wear resistance

The cables have problems such as poor acid and alkali resistance, poor chemical solvents, poor bending resistance, and copper wires are easy to break when moving and using.

This leads to disadvantages such as poor experience comfort for customers during use, low service life of cables, and low safety factor of electric energy transmitted by cables.

On the other hand, there are more mobile cables on the market now that also require higher temperature resistance requirements. Ordinary silicone rubber cables cannot meet the mobile requirements due to their own characteristics, and ordinary PVC and PE wires cannot meet high temperature requirements.
