摘　　要：研究高门尼粘度异戊橡胶(HMIR)在全钢载重子午线轮胎中的应用。结果表明:分别以30,20和20份HMIR等量替代天然橡胶(NR)用于胎面胶、胎体帘布胶和胎肩胶,胎面胶的耐磨和抗切割性能提高,滚动阻力减小;胎体帘布胶的300%定伸应力、撕裂强度和粘合性能相当;胎肩胶的300%定伸应力和撕裂强度增大,拉伸强度略减小;采用HMIR部分等量替代NR试制的全钢载重子午线轮胎的充气外缘尺寸、强度和耐久性能均达到国家标准,实际使用性能与全NR轮胎相当或略优。In this study,the application of high Mooney viscosity isoprene rubber(HMIR)in truck and bus radial tire was studied.In the tread compound,30 phr of HMIR were used to replace natural rubber(NR)by equal weight,and the test results showed that the abrasion resistance and cutting resistance of the tread compound were improved and the rolling resistance was reduced.In the carcass ply compound and shoulder compound,20 phr of HMIR was used to replace natural rubber(NR)by equal weight,and it was found that the modulus at 300% elongation,tear strength and adhesion properties of the carcass ply compound were equivalent,and the modulus at 300% elongation and tear strength of the shoulder compound increased and the tensile strength decreased.By using HMIR to replace part of the NR by equal weight in the tire compounds,the inflated peripheral dimension,strength and durability of the truck and bus radial tire all met the requirements of the national standards,and the actual service performance was equivalent to or slightly better than that of the all NR tire.
