摘　　要：研究季铵盐在工程机械轮胎胎面胶中的应用。结果表明:随着季铵盐用量的增大,胶料的硫化速度提高,交联密度增大,硫化胶的硬度和定伸应力增大,拉断伸长率减小,耐磨性能提高,撕裂强度和抗切割性能先提高后降低,季铵盐的最佳用量为0.1份;成品轮胎的工艺性能良好,质量优异,解决了常见的花纹圆角和胎面缺胶问题。The application of quaternary ammonium salt was investigated. The results showed that, as the addition level tread compound of off the-road tire of quaternary ammonium salt increased,the curing rate of the compound increased,the crosslink density increased,the hardness and modulus of the vulcanizate increased, the elongation at break decreased, the wear resistance was improved, and the tear strength and cut resistance increased at first and then decreased. It was found that the optimal addition level of quaternary ammonium salt was 0. 1 phr. The processability of the compound was good,and the quality of the finished tire was excellent. The quality issues such as rounded pattern and tread defect were resolved.
