CROSSLINKED RUBBER, RUBBER-SHEATHED CABLE USING SAME, AND CROSSLINKED RUBBER PRODUCING METHOD
A crosslinked rubber is composed of rubber molecules, which, before crosslinking, contain hot dissociatable and cold associatable crosslinking groups to dissociate from each other in a hot state and associate together in a cold state, and silane crosslinking groups, and which, after molding, are silane-crosslinked together by a silanol condensation reaction of the silane crosslinking groups together with moisture, with the hot dissociatable and cold associatable crosslinking groups associated together.
1 . A crosslinked rubber, comprising
rubber molecules, which, before crosslinking, contain hot dissociatable and cold associatable crosslinking groups to dissociate from each other in a hot state and associate together in a cold state, and silane crosslinking groups, and which, after molding, are silane-crosslinked together by a silanol condensation reaction of the silane crosslinking groups together with moisture, with the hot dissociatable and cold associatable crosslinking groups associated together.
2 . The crosslinked rubber according to claim 1 , wherein
the hot dissociatable and cold associatable crosslinking groups are hydrogen bonding groups, ionic bonding groups, or dynamic covalent bonding groups.
3 . A rubber-sheathed cable using the crosslinked rubber according to claim 1 .
4 . A crosslinked rubber producing method, comprising:
before crosslinking, introducing hot dissociatable and cold associatable crosslinking groups into rubber molecules, the hot dissociatable and cold associatable crosslinking groups being dissociated from each other in a hot state and associated together in a cold state;
introducing silane crosslinking groups into the rubber molecules with the hot dissociatable and cold associatable crosslinking groups introduced therein;
molding the rubber molecules with the hot dissociatable and cold associatable crosslinking groups and the silane crosslinking groups introduced therein; and
silane-crosslinking the rubber molecules together by a silanol condensation reaction of the silane crosslinking groups together with moisture, with the hot dissociatable and cold associatable crosslinking groups associated together.
5 . The crosslinked rubber producing method according to claim 4 , wherein
the hot dissociatable and cold associatable crosslinking groups are hydrogen bonding groups, ionic bonding groups, or dynamic covalent bonding groups.
