摘　　要：分析导电轮胎烟囱胶缺陷的产生原因并提出相应的解决措施。主要缺陷是烟囱胶被胎冠胶覆盖而不能外露从而无法形成贯穿胎面的导电通路。预口型形状设计不合理、口型板底板倒角宽度设计偏大、烟囱胶预口型出口宽度设计不合理、烟囱胶门尼粘度偏低、现场管控不到位等均会导致烟囱胶不外露。通过调整烟囱胶口型和预口型形状、改善胶料的门尼粘度、加强现场管控等措施,可解决烟囱胶不外露问题。The causes for the defects of conductive tire chimney rubber were analyzed and the corresponding solutions were proposed.The main defect was that the chimney rubber was covered by crown compound and could not exposed on the tread surface to form the conductive pathway extending through the tread.It was found that the main causes were poor design of the preformer shape,oversize design of the chamfering width of the bottom of die plate,unreasonable design of the outlet width of the preformer of chimney rubber,low Mooney viscosity of chimney rubber,and poor on-site control.By adjusting the die and preformer shape of chimney rubber,improving the Mooney viscosity of the compound,and strengthening onsite management and control,the defects of the chimney rubber could be solved.
