Description

technical field [0001] The invention provides an epoxy resin adhesive used for bonding fluorine rubber and metal, and belongs to the technical field of adhesives. Background technique [0002] Due to the dense surface, high polarity and high strength of the metal, the selection of adhesives for metal materials should use phenolic resins, modified epoxy resins, polyurethanes, acrylates and other adhesives, as well as hot melt adhesives and inorganic adhesives. [0003] The bonding of fluororubber to metal includes the bonding of unvulcanized fluororubber to metal and the bonding of vulcanized fluororubber to metal. For the former, silicone adhesives, mixed adhesives containing tackifiers or isocyanate adhesives are generally used; for the latter, epoxy resin adhesives are generally used. [0004] However, when using epoxy resin adhesives to bond fluororubber and metal, its heat resistance is not good, and the process is cumbersome, and fluororubber needs to be vulcanized, wh...
