Abstract

The invention discloses an external thermoplastic elastomer material of a halogen-free flame-retardant cable. The material is prepared from, by weight, 105-115 parts of TPU, 30-40 parts of SEBS, 6-7 parts of organic rectorite, 1-3 parts of tetraisopropyl titanate, 15-25 parts of precipitated silica, 10-20 parts of plasticizer, 10-20 parts of mica, 4-6 parts of talcum powder, 4-6 parts of fire retardant, 3-5 parts of lubricant, 0.2-0.6 part of antioxidant, 3-5 parts of silane coupling agent with the fineness smaller than 300 and 4-6 parts of carbon black. The defects in the prior art are overcome, and the comprehensive performance of resisting oil, resisting heat, being soft, good in resilience force and low in smoke, resisting solvents and cold and the like is achieved.

Description

technical field [0001] The invention relates to the technical field of cable outer covering materials, in particular to a thermoplastic elastomer halogen-free flame-retardant cable outer material and a preparation method thereof. Background technique [0002] As the second largest industry in the national economy, wire and cable have been widely used in the transmission of various types of electric energy and signals. Compared with other materials, halogen-free flame-retardant thermoplastic elastomers are the preferred materials for various types of wire and cable insulation and sheathing due to their light specific gravity, easy processing and molding, good comprehensive mechanical properties and excellent electrical insulation properties. [0003] Thermoplastic polyurethane (TPU) refers to a type of elastomeric material polymerized from diisocyanate, polyol and chain extender. It has the characteristics of high strength, high elasticity, wear resistance, oil resistance and...
