钢丝内嵌轻型液压排吸软管的研制

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 reinforcement 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
