研究工程机械轮胎胎体胶混炼工艺改进对胶料性能的影响。结果表明：通过将炭黑分2段加入，并将防老剂和塑解剂分开加入，混炼效率提高，塑解剂效能得到保护；与改进前胶料相比，改进后胶料的门尼粘度降低，硫化特性变化不大，硬度、定伸应力、拉伸强度和撕裂强度相当，H抽出力明显增大，自粘性显著提高，流动性好，压延半成品尺寸稳定性提高。

The mixing process of carcass compound of OTR tire was optimized and its influence on the properties of the compound was studied. In the optimized process, carbon black was added in two stages, and the antioxidant and peptizer were added separately. The mixing efficiency was then improved and peptizer was effectively protected. The experimental testing results showed that after optimization the Mooney viscosity of the compound was reduced, curing characteristic didn’t change, the hardness, tensile modulus, tensile strength and tear strength of the vulcanizates were also kept unchanged, but the H pull-out force and tackiness of the compound increased significantly, the flowability was better, and the dimensional stability of the calendered semi-finished products was improved.
