研究抗撕裂树脂A-100在矿用全钢载重子午线轮胎胎面胶中的应用。结果表明：与未添加抗撕裂树脂A-100的胎面胶相比，添加3份抗撕裂树脂A-100的胎面胶硬度和拉伸强度相当，定伸应力略低，拉断伸长率和撕裂强度明显提高（有利于减少胎面裂口、崩花和掉块问题）；用抗撕裂树脂A-100胎面胶制备的矿用全钢载重子午线轮胎抗切割性能和抗刺扎性能优异，使用寿命明显延长。%The application of tear strength improving resin A-100 in the tread compound of mining TBR tire was investigated in this study. Compared with the tread compound without A-100, the hardness and tensile strength of the compound with 3 phr A-100 were similar, the tensile modulus was a little lower, but the elongation at tensile break and tear strength were signiifcantly improved, which could reduce the tread quality issues such as cracking, chunking and breaking. The mining TBR tire with A-100 iflled tread compound showed excellent cut resistance and puncture resistance, and had signiifcantly longer service life.
