【摘要】 ExolitOP930是Clariant公司近年来开发出来的一种适用于环氧树脂(EP)的二烷基次膦酸盐阻燃剂,其主要组分为二乙基次膦酸铝。本文着重研究了ExolitOP930/EP阻燃复合材料的阻燃性能、热分解性能、机械性能及玻璃化转变温度Tg。研究结果表明,OP930的含量仅需15wt%就可以使Al(MHP)/EP复合材料的氧指数值(LOI)达到29.8,垂直燃烧实验达到V-0级标准,产物600℃的残炭率为22.36%。此外,OP930/EP复合材料综合性能良好,不同OP930含量的复合材料的机械性能、热性能稳定性能以及玻璃化转变温度Tg与原材料相比,变化不大。更多还原

【Abstract】 Exolit OP930 (abbreviate OP930) product based on aluminum (diethyl phosphinate) is a new class of flame retardants for the use in epoxy resin (EP).In this paper, the mechanical properties, the morphologies of fracture surfaces, thermal stability, glass transition temperature(Tg) and flame retardant of OP930-EP composites with different composition have been studied. The composites exhibit satisfying thermal properties and a high limiting oxygen index (LOI) value as well as good compatibility with the matrix. Compared to neat resin, the mechanical properties of composites are also on a very good level.更多还原
