AI Technical Summary
Existing PP materials are prone to mold fouling when ammonium polyphosphate and hypophosphite flame retardant systems are added, which affects product quality and production efficiency. In addition, their flame retardant performance is insufficient, limiting their application in fields with high flame retardant performance requirements.
A PP composite material was prepared by melt blending a specific ratio of PP resin, monohydrophosphinate, brominated flame retardant and stearate to avoid mold fouling and improve flame retardant properties.
This invention achieves good flame retardant properties in PP composite materials without generating mold deposits, making them suitable for manufacturing electrical control boxes for air conditioners, refrigerators, and washing machines.
