摘　　要：轮胎胎冠挤出样板合理的开型系数是提升胎冠质量稳定性、降低制品返回率的有效手段,通过对试验数据的统计分析,能够真实有效的反映出样板开型系数与胎冠挤出质量的关系,通过优化样板开型系数可有效解决胎冠气孔率大、尺寸重量波动、自黏性差、排胶温度高等难题,从而提升胎冠挤出质量,稳定轮胎产品综合性能。The reasonable opening coefficient of tire crown extrusion template is an effective means to improve the stability of tire crown quality and reduce product return rate.Through statistical analysis of experimental data,it is possible to accurately and effectively reflect the relationship between the sample opening coefficient and the extrusion quality of the tire crown.By optimizing the template opening coefficient,the problems of high porosity,size and weight fluctuations,poor self-adhesiveness,and high discharge temperature of the tire crown can be effectively solved,thereby improving the extrusion quality of the tire crown and stabilizing the comprehensive performance of the tire product.
