钢丝内嵌轻型液压排吸软管的研制

Development of Wire Embedded Light-weight Hydraulic Hose

介绍钢丝内嵌轻型液压排吸软管的配方设计和生产工艺。内层胶以丁腈橡胶(NBR)/丁苯橡胶(SBR)(并用比为80/20)为主体橡胶,补强材料为炭黑N550/N774(并用比为35/35);中层胶和外层胶分别以NBR/SBR(并用比为40/60)和SBR/氯丁橡胶/氯化聚乙烯橡胶(并用比20/30/50)为主体橡胶。通过对胶管成型和硫化设备的改造,实现了胶管的自动化生产。胶管的成品性能满足SAE J 517 100R4标准要求。

The development of wire embedded light-weight hydraulic hose for suction and discharge applications was described. The matrix material of inner layer was NBR/SBR （80/20）, and the rein- forcement filler was carbon black N550/N774（35/35）. The matrix materials of middle and outer layers were NBR/SBR（40/60）and SBR/CR/CM（20/30/50）,respectively. The automated production of hose was achieved by upgrading the molding and curing equipment. The properties of the hose met the requirements of SAE J 517 100R4.
