| 中文摘要: |
| 研究高寒和普通冬季轮胎胎面胶的配方与性能。结果表明：天然橡胶和顺丁橡胶适用于高寒地区冬季低速轮胎，溶聚丁苯橡胶适用于普通地区冬季高速轮胎。冬季轮胎胎面胶配方中加入硫酸镁后，对其抗湿滑性能和冰雪路面行驶性能造成不利影响；以抗湿滑助剂部分等量替代白炭黑后，胎面胶的损耗因子增大、低温条件下的储能模量下降，其抗湿滑性能和冰雪路面行驶性能提高；亚甲基受体和给体的加入也会提高胎面胶的抗湿滑性能和冰雪路面行驶性能。 |
| 英文摘要: |
| The tread formula and property of winter tires for general region and extremely cold region were investigated.The results showed that,natural rubber and butadiene-rubber were applicable for low-speed winter tire for extremely cold region,and solution styrene butadiene rubber was suitable for high-speed winter tire in general region.When magnesium sulfate was added to winter tire formula,it caused negative impacts on the wet skid resistance and performance on icy pavement.By using wet resistance additive to replace part of silica,the loss factor of the tread compound increased,and the storage modulus at low temperature decreased,which was beneficial to the wet skid resistance and performance on icy pavement.Addition of methylene receptor and donor could also improve the wet skid resistance and performance on icy pavement. |
