【摘要】 聚氨酯橡胶与环氧树脂相比,具有弹性;与氯丁橡胶等柔性粘合剂相比,具有耐低温、耐海水、与经化学处理后的聚丙烯结合力好等特点。选用聚氨酯灌封海洋浮标系缆接头,采用改进后的工艺,做到常温固化,并使聚氨酯性能达到预期的效果。浮标在海上工作半年,聚氨酯灌封的系缆接头工作正常,无一损坏。更多还原

【Abstract】 Elastic polyurethane resists low temperature and sea water better than chlor- oprene rubber and other elastic binders. polyurethane can easily combine with po- lypropylene mooring line after chemical treatment. The mooring line eye-hook of marine data buoy is sealed with polyurethane. Improved teAnology makes polyu- rethane cure at room temperature with good quality. Eye-hooks sealed with this method survived very well for half a year when the buoy operated at sea. None of them has been damaged.更多还原
