Abstract

The invention belongs to the technical field of polymer materials and relates to a modified halogen-free flame-retardant thermoplastic elastomer cable material and a production method thereof. The modified halogen-free flame-retardant thermoplastic elastomer cable material is characterized by comprising butadiene-styrene copolymer, polyphenyl ether resin, polyacetylene or polypropylene, polyolefin elastomer, plasticizer, mica, aluminum hydroxide, talcum powder, ethylene vinyl acetate copolymer, polytetrafluoroethylene, lubricant, antioxidant, silicone less than 300 meshes in fineness, and carbon black. The invention further discloses the production method of the modified halogen-free flame-retardant thermoplastic elastomer cable material. The modified halogen-free flame-retardant thermoplastic elastomer cable material has the advantages such as good processability, high flame retarding rating, non-toxicity, low density, good tear resistance, good acid and alkali resistance and good weatherability, with excellent water resistance, cracking resistance and dripping resistance; the modified halogen-free flame-retardant thermoplastic elastomer cable material never ages or separates out under high temperature and high dampness for a long time, the mechanical properties are kept good, and the electrical performances have no evident change.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a cable material and a manufacturing method thereof, in particular to an improved halogen-free flame-retardant thermoplastic elastomer cable material and a manufacturing 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 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,...
