Problems solved by technology

[0002] With the rapid development of the economy, wires and cables have been widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of all countries in the world; when the cable burns, a large amount of smoke is released. Toxic and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, causing serious losses of life and property.

Abstract

The invention discloses a thermoplastic polyurethane elastomer cable material and a preparation method thereof. The material is composed of: modified chlorosulfonated polyethylene, maleic-anhydride-grafted polyolefin elastomer, thermoplastic polyurethane elastomer, white carbon black, limestone powder, zinc oxide, a vulcanizing agent MOCA, an anti-aging agent OD, dibutyl phthalate, methyl triethoxysilane, diphenylamine, Tween 80, chlorinated paraffin, and zinc borate. According to the invention, modified chlorosulfonated polyethylene, maleic-anhydride-grafted polyolefin elastomer, and thermoplastic polyurethane elastomer high-molecular materials are used as base materials of the material; with dibutyl phthalate, inter-solubility of the components are improved; and a plurality of functional auxiliary materials are added. Therefore, the defect of the incapability of being used under high-temperature environment of cable materials is solved. The material has good flame resistance, greatly improved mechanical property, and good dynamical performance.
