【摘要】 用热重法-微分热重法(TG-DTG)和差热分析(DTA),测定加入不同防老剂的过氧化物预硫化胶乳(PPVL)胶膜的有关热动力学参数来评价它们的耐热氧降解性能,筛选出的防老剂2246、2246/264能给PPVL胶膜好的抗热氧降解性能,2246、264并用有协同效应。

【Abstract】 The thermo-oxidative degradation of the peroxide prevulcanized latex (PPVL) film was determined with TG-DTG and DTG. The thermo-dynamic parameters of the PPVL films with different anti-agers added were determined in order to evaluate their thermo-ox- idative resistance. PPVL films added with selected anti-agers 2246 and 2246/264 displayed ed thermo-oxidative resistance. The combination of anti-agers 2246 and 264 shows syner- getic action.
