研究多功能交联剂WY988在全钢载重子午线轮胎胎肩垫胶中的应用。结果表明，在胎肩垫胶中加入多功能交联剂WY988，胶料的抗硫化返原性能显著改善，定伸应力增大，老化前后的拉断永久变形显著减小，成品轮胎的耐久性能提高。%The application of multifunctional crosslinking agent WY988 in the shoulder compound of TBR tire was studied. The results showed that with WY988, the anti-reversion properties of the compound were signiifcantly improved, the modulus of the vulcanizates increased, the permanent tensile set was low even after aging, and the endurance performance of the ifnished tire was improved.
