The present invention relates to a thermoplastic low-retardant non-halogen-based flame retardant elastomer cable material having ultra-low flame retardancy, ethylene vinyl acetate copolymer, polyolefin elastomer, EPDM rubber, hydrogenated base oil, alkoxysilane, flame retardant in a high-speed mixer, organic silica gel resin , Sodium silicate, maleic anhydride graft polyolefin elastomer, diammonium phosphate, broad leaf cedar bark, pine bark, yew, chitosan, citrus extract, ginger extract, chlorinated polyethylene, polytetrafluoroethylene, polyimide mixed and sealed It is put together in a mixer, and each component is uniformly mixed to form a soft jelly. The obtained soft jelly form material is placed in a single screw extruder, mixed, plasticized, and melt-extruded to extract and remove moisture and volatile substances, and after cooling, particles are made and dried to obtain a cable material. The present invention produces a non-halogen-based flame retardant cable material having ultra-low smoke, and the cable material has a relatively small amount of fumes produced by combustion when burning in a large area. |
