▎ 摘  要

NOVELTY - Repairing material comprises an component (A) and a component (B) having a reactive functional group molar ratio of 1:(1.15-1.2). The component (A) comprises 60-80 pts. wt. amino terminated polyether and 25-35 pts. wt. polyester polyol. The component (B) comprises 90-95 pts. wt. hexamethylene diisocyanate trimer and 10 pts. wt. isocyanate-modified graphene oxide. USE - The repairing material is used for cable sheathing. ADVANTAGE - The repairing material has flexible structure, high strength and toughness, high degree of crosslinking, fast repairing and excellent water resistance effect, improved rigidity, increased strength of the material and complete curing within 10 minutes, and is sufficient for filling the gap to be repaired and rapidly formed at room temperature for 3 seconds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the use of the repairing material for cable sheathing comprising partially vacuuming the damaged portion of the cable, extruding the repairing material to fill the damaged portion and curing at room temperature.
