开发了一种新型阻燃剂，硅橡胶纳米粒子（S-ENP），其Tg为−120°C，粒径为100 nm，并用作聚酰胺6（尼龙-6）的改性剂。结果表明，S-ENP不仅能提高尼龙6的韧性和阻燃性能，而且能促进未改性粘土在尼龙6基体中的剥离。研究还发现，S-ENP和尼龙6中的片状粘土对尼龙6具有协同阻燃作用。制备了一种具有高韧性、高耐热性、高刚性和良好流动性的尼龙6/未改性粘土/S-ENP阻燃纳米复合材料，并提出了协同阻燃机理。
A novel flame retardant, silicone elastomeric nanoparticle (S-ENP) with Tgof −120°C and particle size of ∼100nm has been developed and used as a modifier for polyamide 6 (nylon-6). It has been found that S-ENP can not only increase the toughness and improve the flame retardancy of nylon-6 but also helps unmodified clay exfoliate in nylon-6 matrix. It has been also found that the S-ENP and exfoliated clay platelet in nylon-6 have a synergistic flame retardant effect on nylon-6. A novel flame retardant nanocomposite of nylon-6/unmodified clay/S-ENP with high toughness, high heat resistance, high stiffness and good flowability has been prepared and a mechanism of synergistic flame retardancy has also been proposed.
