【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。更多还原

【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.更多还原
