Abstract

The invention discloses a low-smoke halogen-free flame retardant cable material preparation method. A cable material has high tensile strength, wide suitable temperature range, halogen-free and low-smoke characteristics, little impact on the environment, mechanical mechanics of a product and convenient extrusion shaping operation of the product, so that the prepared product has uniform performanceand smooth surface, and the method is more suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing a cable material, in particular to a method for preparing a low-smoke, halogen-free, flame-retardant cable material. Background technique [0002] Cable is a wire product used to transmit electric energy, magnetic energy, information and realize electromagnetic energy conversion. The cable is mainly composed of a conductor, a conductor shield, an insulation layer, an insulation shield, a buffer layer, a metal sheath, and an outer sheath. Most of the outer sheaths are located on the outermost layer of the cable to protect the cable. At present, plastics and rubber are mostly used as the main materials. However, the traditional cable materials have poor flame retardancy and are prone to fire, causing property damage and casualties. With the rapid development of my country's modern industry, safety and prevention measures should be more and more perfect. In many large public places, in order to avoid the s...
