Thermoplastic polyurethane elastomer cable material and preparation method thereof

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.

Description

technical field [0001] The invention discloses a thermoplastic polyurethane elastomer cable material and a preparation method thereof, belonging to the field of cable manufacturing. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in various industries and fields.
