烷基硫代磷酸锌硫化促进剂对天然橡胶老化性能影响研究

摘要

Natural rubber was vulcanized with the aid of zinc dialkydithiophosphates and other common vulcanizing accelerators and the resultant samples were aged in hot air. The mechanical properties of the samples were measured before and after aging and the anti-aging performance were compared. The experiment results indicated that the sample with zinc diisopropyldithiophate possessed excellent anti-aging performance.%研究了烷基硫代磷酸锌和其他常用硫化促进剂对天然橡胶硫化胶的老化性能的影响.实验表明二异丙基二硫代磷酸锌能赋予天然橡胶硫化胶优良的耐热空气老化性能.
