Thermoplastic low flame retardant non-halogen flame retardant elastomer cable material with ultra low smoke

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. A thermoplastic low-smoke halogen-free flame retardant elastomer cable material with ultra-low smoke generation. The cable material is prepared by placing an ethylene-vinyl acetate copolymer， a polyolefin elastomer， an ethylene-propylene-diene rubber， a hydrogenated base oil， an alkylsiloxane and a flame retardant into a high speed mixer， adding an organic silica gel resin， sodium silicate， a maleic anhydride-grafted polyolefin elastomer， diammonium phosphate， cedar bark， pine bark and taxus cuspidate thereto， adding chitosan， a citrus extract， a fresh ginger extract， a chlorinated polyethylene resin， polytetrafluoroethylene and polyimide thereto， putting the materials into an internal mixer together， and mixing same uniformly so as to form a soft gel-like material; placing the obtained soft gel-like material into a single screw for mixing， plasticizing and melt extrusion， removing moisture and volatile materials， and performing cooling， granulation and drying. When a large part of the cable material is burning， the smoke release produced by burning is relatively low.
