摘要
从人员操作、生产设备、胶料性能和生产工艺等方面,分析全钢载重子午线轮胎内衬层气泡产生原因,并提出相应解决措施。通过改变压辊材质,优化压力参数和挤出生产参数,界定压延机温度和物料存放区域,增大挤出供胶压力和过渡层与气密层贴合角度,调整过渡层与气密层收缩率,加强终炼胶门尼粘度控制及重新设计异形组合压辊,内衬层层间气泡问题得到了有效解决,大幅减少了成品轮胎脱层、胎里气泡和X光检测气泡等问题,提高了轮胎整体性能。
From the aspects of personnel operation,production equipment,compound properties and production process,the causes of bubbles in the inner liner of truck and bus radial tire were analyzed,and corresponding solutions were proposed. By changing the material of the pressure roller,optimizing pressure parameters and extrusion production parameters,defining the calender temperature and material storage area,increasing the extrusion feeding pressure and the bonding angle between the transition layer and airtight layer,adjusting the shrinkage ratio of the transition layer and airtight layer,strengthening the Mooney viscosity control of the final compound,and redesigning the special-shaped combination roller,the interlayer bubble problem of the inner liner was effectively solved,which greatly reduced the problems such as delamination,bubbles in the tire and bubbles detected by X-ray,and improved the overall tire performance.
