摘　　要：介绍全天候轮胎的研发情况。开发的Z-401B花纹全天候轮胎的胎面采用单导向花纹,并配直行和弯折错位分布的密集型刀槽花纹;胎面胶采用高顺式顺丁橡胶、高苯乙烯含量乳聚丁苯橡胶和新型改性溶聚丁苯橡胶并用,补强体系采用高结构炭黑与高分散性白炭黑并用;轮胎的接地印痕接近矩形。成品轮胎试验结果表明,轮胎符合现有生产工艺要求,通过欧盟R117法规认证,部分雪地性能达到国际领先水平,操纵性能和稳定性表现优异。The research and development of all-season tire were introduced.In the Z-401B all-season tire,single oriented pattern and dense sipes with alternated distribution of straight and bending structure were adopted,blends of high cis-BR,high styrene content emulsion SBR and new modified solution polymerized SBR were used for tread compound,and high structure carbon black and highly dispersible silica were jointly applied for reinforcement.The footprint of tire was close to a rectangle.The test results of the finished tire showed that the tire met the production process requirements,it was certified by the EU R117 regulations,the performance on snow road reached international leading level,and the handling performance and stability were excellent.
