Abstract

The invention relates to high-performance flame-retardant polyester fiber and a preparation method thereof. The high-performance flame-retardant polyester fiber mainly comprises the following raw material components of waste mineral water bottle flakes, cubic silicon carbide and a halogen-free flame retardant. The preparation method comprises the following steps of (1) screening, ultrasonically cleaning and drying the bottle flakes; (2) mixing a part of the bottle flakes from a main feeding hole, the cubic silicon carbide and the halogen-free flame retardant, and feeding a mixture into a double-screw extruder from an auxiliary feeding hole; (3) setting extrusion temperature and rotating speed, and performing extruding through a round hole mold to obtain a primary extrudate; and (4) dicing the primary extrudate, mixing the diced primary extrudate with the rest of the bottle flakes, feeding a mixture into the double-screw extruder, performing extruding through a screw hole mold, and performing drawing to obtain the fiber. The polyester fiber prepared by the method is low in raw material cost and low in processing energy consumption, overcomes the defect that polyester is flammable, has excellent flame retardance, thermal property and mechanical property, and can be used in the field of special protective materials.
