摘　　要：研究防老剂4010NA(N)与防老剂D并用对轮胎胎面胶和胎侧胶性能的影响,并与防老剂4010NA进行对比。结果表明:防老剂4010NA(N)/D并用对胶料硫化特性基本没有影响,防老剂4010NA/D并用使胶料的焦烧时间和硫化时间略有缩短;防老剂4010NA(N)胶料的300%定伸应力、拉伸强度和撕裂强度略大于防老剂D胶料,与防老剂4010NA胶料相当;防老剂4010NA(N)/D并用胶料耐热氧老化长效性优于防老剂4010NA/D并用和防老剂D单用的胶料;对于胎面胶,防老剂4010NA(N)/D和防老剂4010NA/D并用的胶料耐磨性能优于防老剂D单用胶料。The effects of antioxidant blend of antioxidant 4010NA（N）and D on the properties of tire tread compound and sidewall compound were studied and compared with antioxidant 4010NA.The results showed that the curing characteristics of the compound were not significantly affected by the use of antioxidant 4010NA（N）/D blend,while the scorch time and curing time were slightly shortened by the use of antioxidant 4010NA/D blend.The tensile modulus at 300% elongation,tensile strength and tear strength of the vulcanizates with antioxidant 4010NA（N）/D blend were slightly higher than those of the vulcanizates with antioxidant D,and similar to the vulcanizates with antioxidant 4010NA.It was found that the long term thermo-oxidative aging resistance of the vulcanizates with antioxidant 4010NA（N）/D blend was better than that with antioxidant 4010NA/D blend and that with only antioxidant D.In addition,the wear resistance of the tread compound with antioxidant 4010NA（N）/D blend or antioxidant 4010NA/D blend was better than that with only antioxidant D.
