Abstract

The invention discloses a preparation method of an anti-corrosion combustion-supporting wire or cable. Firstly, a plurality of wires are intertwisted into a bundle and are sequentially wrapped with aninsulating layer and a shielding layer to obtain wire cores, groups of wire cores are arranged in bundles to form a cable core; a sheath layer wraps the outer side of the cable core; finally, a protective sleeve is coated with a microcapsule particle coating layer to obtain the cable, the sheath layer uses polyvinyl chloride, a stabilizing agent and a plasticizer as main raw materials. Polyvinylchloride has high high-temperature resistance, low-temperature resistance and corrosion resistance; a stabilizer has high heat resistance and weather resistance, the plasticizer has excellent elasticity, weather resistance and mechanical properties, the three components are blended and vulcanized, respective advantages are reserved, in addition, capsaicin released from the microcapsules can repelants and mice without causing other damage, and the microcapsule is environmentally friendly and convenient to use.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to an anti-corrosion and flame-retardant cable and a processing technology. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. It is usually a rope-like cable twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation overlay. They are composed of single-strand or multi-strand wires and soft copper conductors, which are used to connect circuits and electrical appliances. [0003] Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines a...
