摘　　要：试验研究溶聚丁苯橡胶(SSBR)牌号切换对轮胎硫化胎面接头缺胶的影响。研究表明,在半钢子午线轮胎胎面体系中,以SOL 6270M等量替换RC2557S,若保证胎面胶门尼流变等加工性能,则流动性下降,引起胎面接头缺胶。通过调整混炼工艺,提高胶料的流动性,成品轮胎硫化外观得到有效改善。The effect of SSBR brand transition on the tread joint cracking was studied. The test results showed that use of SOL 6270M to replace RC2557S in the tread recipe of steel belted radial tire resulted in the decline of flow property at a similar level of Mooney viscosity,which caused tread joint cracking.By adjusting the mixing process to improve the fluidity,the appearance defects of the finished tire were effectively avoided.
