摘要
采用热空气老化箱常规法结合热重分析(TG)法、差示扫描量热(DSC)法及橡胶加工分析(RPA)法研究两种割胶制度对生胶(NR)硫化胶耐老化性能的影响,结果表明:s/2d/4+ET2.5%割制硫化胶的耐老化性能优于s/2d/3+ET4%割制硫化胶。
The aging resistances of natural rubber （NR） vulcanizates from two tapping system of rubber trees were investigated by the conventional method of hot-air aging combined with thermogravimetry （TG） ,differential scanning calorimetry （DSC） and rubber processing analyzer （RPA）. The results showed that the aging-resistance of NR vulcanizate from tapping system A is better than that of tapping system B.
