Halogen free flame-retardant materials and method for manufacturing the same

Abstract

The disclosure provides a forming method of a halogen-free flame-retardant material. The method includes the followings. A twin-screw extruder including a first zone and a second zone is used. A mixture in the first zone is mixed, melted and heated to form a molten mixture. The mixture includes a halogen-free flame retardant, a wear-resistant modifier, a thermoplastic elastomer, and an antioxidant. In addition, a silane-modified nano-silica aqueous suspension is introduced into the second zone to mix the silane-modified nano-silica aqueous suspension with the molten mixture from the first zone. The first zone and the second zone are continuously connected regions.
