Environment-friendly flame-retardant transparent polyester material and preparation method thereof

The invention provides an environment-friendly flame-retardant transparent polyester material, which is prepared from the following components in parts by mass: 100 parts of thermoplastic polyester resin and 0.5 to 2 parts of flame retardant; the flame retardant is a montmorillonite-silicon-fluorine modified polypropylene ester material with a core-shell structure, montmorillonite and fluorine-silicon elements are located in an inner core, and the proportion of hard monomers in a shell layer is larger than that of the hard monomers in the inner core. The transparent polyester material has excellent flame retardant property. Meanwhile, the invention also provides a preparation method of the material. 本发明提供了一种环保阻燃的透明聚酯材料，包括热塑性聚酯树脂和阻燃剂，以质量份数计，每所述100份热塑性聚酯树脂对应0.5-2份阻燃剂；所述阻燃剂为核壳结构的蒙脱土-硅氟改性聚丙烯酯材料，蒙脱土和氟硅元素均位于内核，且壳层中硬单体的比例大于内核中硬单体的比例。该透明聚酯材料具有优异的阻燃性能。同时，本发明还提供该材料的制备方法。
