| 中文摘要: |
| 介绍脉冲30万次SAE R17系列钢丝编织胶管的研制。胶管由内层胶、骨架层（2层钢丝编织层）、中层胶和外层胶构成。内层胶和中层胶主体材料分别为丙烯腈含量较大和中等的丁腈橡胶，外层胶主体材料为橡塑合金。内层胶、中层胶和外层胶性能符合企业标准要求，成品胶管的各项性能符合SAE J 517 R17标准要求，其中脉冲突破30万次，远超标准要求。 |
| 英文摘要: |
| The development of steel wire braided rubber hose with service life over 300 000 impulse cycles was described.The rubber hose was composed of inner layer， reinforced layers （2 steel wire braided layers），middle layer，and outer layer.The matrix materials of inner and middle layers were NBR with high and medium acrylonitrile contents，respectively.The matrix material of outer layer was rubber-plastic alloy.The properties of inner，middle and outer layers met the requirement specified in the enterprise standard，and the properties of rubber hose met the requirement of SAE J 517 R17 standard.The service life of the rubber hose reached 300 000 impulse cycles that far exceeded the standard requirement. |
