| 摘要 |
本发明系关于一种可用于光纤电缆中之凝胶组合物，其具有油脂之正常稠度但视需要在加热时变成橡胶状黏着性凝胶；制备热可熔性凝胶之方法及制备可接合光纤电缆之方法及光纤电缆。在最广泛意义上，揭示用于光纤电缆之热可熔性油凝胶组合物，其包括：50wt.%至80wt.%基于烃油之含有2wt.%至10wt.% S-EB或S-EP二嵌段共聚物或该等二嵌段共聚物之混合物之油脂样凝胶；及20wt.%至50wt.%基于极性油之含有5wt.%至25wt.% S-EB-S或S-EP-S三嵌段共聚物或该等三嵌段共聚物之混合物之油脂样凝胶。; a method of making the heat-fusible gel, and a method of making a spliceable fiber optic cable, and a fiber optic cable. In the broadest sense, a heat-fusible oil gel composition for fiber optic cable is disclosed, comprising: from 50 to 80 wt.% of a grease-like gel based on a hydrocarbon oil containing from 2 to 10 wt.% of an S-EB or S-EP diblock copolymer, or a mixture of these diblock copolymers, and from 20 to 50 wt.% of a grease-like gel based on a polar oil containing from 5 to 25 wt.% of an S-EB-S or S-EP-S triblock copolymer, or a mixture of these triblock copolymers. |
