环保型丁苯胶SBR1502E在农业子午线轮胎中的应用

研究环保型丁苯胶SBR1502E在农业子午线轮胎胎面胶和胎体帘布胶中的应用。结果表明：用环保型丁苯胶SBR1502E等量代替丁苯胶SBR1502，胎面胶的挤出性能明显改善，排胶温度降低，压延帘布温度降低，覆胶均匀，成型工艺性能良好，拉伸性能变化不大，门尼粘度明显降低，生热降低，弹性提高，耐磨性能及H抽出性能改善、耐热老化性能变化不大；成品轮胎的物理性能变化不大。

Environmental protection styrene-butadiene rubber SBR1502E application in agricultural radial tyre

Research environmental protection styrene-butadiene rubber SBR1502E in agricultural radial tyre tread compound and the application of the tire body fabric glue. Results show that using environment-friendly styrene-butadiene rubber SBR1502E amount instead of styrene-butadiene rubber SBR1502, tread compound extruding performance improvement, exhaust temperature is reduced, rolling curtain temperature is reduced, the glue, molding process performance is good, tensile properties changed little, significantly lower Mooney viscosity, heat production is reduced, improve elasticity and wear resistance and H pull out performance improvement, heat aging properties changed little; The physical properties of the tire changed little.
