Problems solved by technology

[0002] With the needs of the society and the advancement of relevant laws and regulations, low-smoke, halogen-free, flame-retardant cables are playing an increasingly important role in life, and low-smoke, halogen-free, and flame-retardant cables must be used in more and more occasions, but conventional Although the low-smoke halogen-free flame-retardant cable has the characteristics of low smoke emission, it will still have high smoke emission in the place where the large square cable is burned and the wiring is too much, which will also bring harm to lifesaving and escape personnel. Therefore, the market More need for ultra-low smoke or even smoke-free halogen-free flame-retardant cable materials to make better cables
Conventional low-smoke, halogen-free cables are very hard and inelastic, and bending and dragging will cause certain damage to the outer sheath of the cable. The hardness of the material itself caused by the combustion agent is generally around 95A. For better wiring and adapting to the place, it also needs to have a certain degree of flexibility and lower hardness.

Abstract

The invention relates to a low-smoke, halogen-free and flame-retardant thermoplastic elastomer cable material with an ultralow smoke amount. An ethylene-vinyl acetate copolymer, a polyolefin elastomer, an EPDM (ethylene-propylene-diene monomer), hydrogenated base oil, siloxane and a flame retardant are added to a high-speed mixer, organic silicon resin, sodium silicate, maleic anhydride grafted polyolefin elastomers, diammonium hydrogen phosphate, bark of taxus, pine bark, taxus cuspidate, chitosan, a citrus extract, a fresh ginger extract, chlorinated polyethylene resin, polytetrafluoroethylene and polyimide are added and put in an internal mixer, all components are mixed uniformly, and soft jelly is formed; the soft jelly is put in a single screw for mixing, plasticization and melt extrusion, water and volatile substances are extracted, cooling, granulation and drying are performed, and the cable material can be obtained. The low-smoke, halogen-free and flame-retardant cable material with the ultralow smoke amount is produced and releases less smoke during large-area burning.
