摘要
利用对甲基苯磺酸柱撑改性的超分子水滑石制备出了不饱和聚酯树脂/超分子水滑石阻燃复合材料。用X射线衍射分析(XRD)观察超分子水滑石(LDH-PTS)层间距的变化,用热重分析(TG)、氧指数(LOI)测试和水平燃烧测试研究了其阻燃性能,并考察了复合材料的力学性能。结果表明,水滑石层间距由LDH-PTS的1.73nm增大到复合材料的2.077nm,加入质量分数为3%的LDH-PTS的复合材料与纯不饱和树脂相比,LOI由21%提高到23.30%,T50%由390.3℃提高到了400.3℃,使残炭率增加了3.7%,水平燃烧速度比纯不饱和树脂降低了20.24%,同时复合材料的拉伸强度与纯不饱和树脂相比基本相同。
Flame retarded unsaturated polyester resin/supramolecular hydrotalcite composite was prepared by using supramolecular hydrotalcite （LDH-PTS）. The change of the supramolecular hydrotalcite interlayer spacing was studied by means of XRD, the flame retardance of the composite was studied by means of TG method, LOI test and horizontal burning test, and the mechanical properties of the composite were also tested. The results showed the interlayer spacing of LDH increased from 1.73 nm in LDH-PTS to 2. 077 nm in the composite. Compared with unsaturated polyester resin, the addition of 3% （mass fraction） of LDH-PTS improved the flame retardance remarkably, LOI increased from 21% to 23.30 % , T50% rose from 390.3℃ to 400. 3 ℃, char residue rate increased by 3.7% , the speed of horizontal burning decreased -by 20.24% , while the tensile strength of the composite was basically same with that of unsaturated polyester resin.
