High weather resistant and flame-retardant cable

Abstract

The invention discloses a high weather resistant and flame-retardant cable, which comprises a conductor, an insulating layer cladding the conductor, a packing layer cladding the insulating layer, a shielding layer cladding the packing layer, an armor layer cladding the shielding layer and an outer sheath cladding the armor layer. The outer sheath comprises the following raw materials by weight part: 45-48 parts of styrene butadiene rubber, 25-27 parts of chloroprene rubber, 17-20 parts of natural rubber, 10-13 parts of phase change control microcapsule, 0.8-1.2 parts of sulfur powder, 1.6-2.4 parts of an accelerator AA, 2.5-2.8 parts of an accelerator MZ, 8-11 parts of hard clay, 6-9 parts of sepiolite, 6-8 parts of lanthanum oxide, 5-7 parts of mica powder, 2.6-3 parts of a monoalkoxy pyrophosphate type titanate coupling agent, 2.4-2.8 parts of coconut oil, 3-6 parts of naphthenic oil, 4-6 parts of antimony trioxide, 3-5 parts of melamine, 4-6 parts of red phosphorus masterbatch, 5-8 parts of barium stearate, 1.5-2.5 parts of an anti-aging agent H, and 1.3-1.6 parts of an anti-aging agent DFC-34.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a highly weather-resistant and flame-retardant cable. Background technique [0002] Cables are used in a wide range of environments, and special attention should be paid to the use of cables in places with complex geographical conditions and drastic environmental changes. As the "first line of defense" against the external environment, the cable outer sheath often uses rubber materials. However, when faced with sudden changes in ambient temperature, traditional rubber materials often deform, causing cracks, damage, etc., thus Destroy the integrity of the cable structure; at the same time, due to the flammability of rubber materials, attention should be paid to its flame retardancy when using cables in some high-temperature environments. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a highly weathe...
