粘土胶老化防护体系的研究

Study of the Protection System of Aging for Clay-Rubber Masterbatch

主要讨论了有关粘土胶防老剂的选用、配用和筛选。通过采用天然橡胶塑性保持率的测定方法、橡胶热空气老化试验方法、热分析技术、扫描电镜分析等，对有关防老剂及其配方的性能进行了比较，优选出防老剂Ｃ－ ４ ＃ ———酚类与硫化物复配物等一系列对粘土胶有优异的耐热氧老化效果的防老剂及其配方。

The selection and fit of age resister was mainly discussed.The properties of age resisters and formulations were compared by the determination of NR plastic retention,the measure of thermal air aging of rubber,thermal analysis technology and analysis of scanning electron microscope.A series of antioxidants such as C-4 # and formulations which had excellent effects to thermal-oxidative aging of clay masterbatch were selected.
