AI Technical Summary
Existing polyolefin elastomers exhibit performance degradation under high-temperature conditions, leading to reduced long-term material stability and service life. They also present processing difficulties and fail to maximize flame retardant properties.
A toughened halogen-free heat-resistant polyolefin elastomer was prepared by compounding ethylene-vinyl acetate copolymer, polyolefin elastomer, compatibilizer, halogen-free flame retardant, flame retardant synergist, antioxidant and lubricant through a twin-screw extruder. A flame retardant with PN bond expansion structure and triazine ring was prepared by compounding organosilicon flame retardant with aluminum hydroxide and adding high viscosity organosilicon mixture. B element was introduced to form a protective glass transition layer.
It significantly improves the flame retardant properties, thermal stability, and processability of the material, extends the heat resistance life of the material, and ensures stability and uniformity under high temperature conditions.
