摘要
采用熔融共混法制备了蒙脱土(MMT)与膨胀阻燃剂(IFR)阻燃的三元乙丙橡胶/乙酸乙烯酯橡胶(EPDM/EVM)共混胶,用X射线衍射仪对其结构进行了表征,考察了MMT对共混胶力学性能、阻燃性能与热稳定性的影响。结果表明,在含有MMT的膨胀阻燃EPDM/EVM共混胶中,形成了插层型/剥离型的共存体系;MMT可显著提高膨胀阻燃共混胶体系的力学性能、热稳定性和成炭性,但对极限氧指数贡献不大。
The intumescent flame retardant ethylene-pro- pylene-diene monomer（ EPDM ）/ethylene-vinyl acetate rubber （EVM） blends were prepared with montmorillonite （MMT） and intumescent flame retardant（IFR） through melt blending process. The structure of the blends was characterized by X- ray diffractometer, and the mechanical properties, flame re- tardancy, thermal stability of the blends were investigated. The results showed that the intercalated/exfoliated structure was formed in intumescent flame retardant EPDM/EVMblends contained MMT. MMT could improve the mechanical properties, thermal stability and char forming characteristics of intumescent flame retardant EPDM/EVM blends evidently, however, MMT showed little effect on limiting oxygen index.
