摘要
研究了硅烷偶联剂KH-550和甲基丙烯酸缩水甘油酯/苯乙烯/过氧化二异丙苯(GMA/St/DCP)多单体"原位"增容改性Mg(OH)2/红磷复配阻燃剂对天然橡胶/线性低密度聚乙烯动态硫化热塑性弹性体(NR/LLDPE TPV)的阻燃效果、静态和动态力学性能及耐热分解性能的影响。结果表明,"原位"增容改性有利于改善NR/LLDPE TPV的阻燃性能和力学性能;当m[Mg(OH)2]/m(红磷)=80/8时,"原位"增容改性阻燃NR/LLDPE TPV的氧的最低浓度(LOI)达到25.6%(体积分数),燃烧时无黑烟和熔滴滴落现象,力学性能保持率较高并具有较好的耐寒性和耐热分解性能。
The effects of the silane coupling agent KH-550 modified and GMA/St/DCP multi-monomer "in situ" grafting the magnesium hydroxide/red phosphorus flame-retardant system on flame-retardant effects,static and dynamic mechanical properties,resistance to thermal decomposition of NR/LLDPE TPV were investigated.The results showed that,the mechanieal properties and flame-retardant effects of TPV have been enhanced with the "in situ" grafting by GMA/St/DCP system in the process of dynamic vulcanization.When the magne...
