Flame-retardant wear-resistant cable and preparation method thereof

Abstract

A flame-retardant wear-resistant cable disclosed by the present invention comprises a cable core and a flame-retardant wear-resistant sleeve, the flame-retardant wear-resistant sleeve comprises an insulating layer arranged outside the cable core, a reinforcing layer wrapping the aerogel insulating layer, and a sheath layer wrapping the reinforcing layer, a flame-retardant cavity is formed between the sheath layer and the reinforcing layer, and the flame-retardant cavity is filled with a flame retardant. The flame-retardant wear-resistant sleeve is arranged outside the cable core, the flame-retardant wear-resistant sleeve is composed of the sheath layer, the wear-resistant layer and the reinforcing layer, the wear-resistant cavity formed between the wear-resistant layer and the sheath layer can achieve a wear-resistant effect, meanwhile, the high-ignition-point quick-drying adhesive filled in the wear-resistant cavity can repair a damaged part after the wear-resistant layer is damaged, the repaired damaged part is white, and the service life of the cable is prolonged. The observation is convenient; the flame retardant is filled in the flame-retardant cavity, so that the flame-retardant effect can be achieved, the internal damage of the cable is avoided, and the service life is prolonged; and the anti-interference effect of the cable is also improved by the instant adhesive filled in the wear-resistant layer and the flame retardant filled in the flame-retardant cavity.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant and wear-resistant cable and a preparation method thereof. Background technique [0002] Cables are usually made by twisting several or several groups of conductors (at least two in each group), each group of conductors is insulated from each other, and often twisted around a center, and the entire outer surface is covered with a highly insulating covering . The cable has the characteristics of inner energization and outer insulation. Flame retardant cable refers to the cable in which the sample is burned under the specified test conditions, after the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual burn can be extinguished within a limited time. The fundamental characteristic is: in the event of fire, it may be burnt out and cannot operate, but it can prevent the spread of fire. In layman'...
