Embodiment 1
[0039] According to the ratio of parts by mass, add 16 parts of hydrogenated carboxylated nitrile rubber, 2.5 parts of fumed silica, 2 parts of epoxy-terminated liquid polysulfide rubber, 4 parts of novolac epoxy resin, and 0.3 parts of iron oxide red to the double rollers in sequence Mix with an open mill, crush evenly after mixing, then add the crushed rubber into the stirring tank, add 74.2 parts of mixed solvent, 0.3 parts of A-Link 599 silane coupling agent, bis-(3- (triethoxysilane) propyl)-disulfide silane coupling agent 0.7 parts, stirred at a stirring speed of 60 rpm for 4 hours until the glue was uniform and then discharged.
Embodiment 2
[0041] According to the ratio of parts by mass, add 10 parts of hydrogenated carboxylated nitrile rubber, 4 parts of fumed silica, 4 parts of epoxy-terminated liquid polysulfide rubber, 1 part of novolac epoxy resin, and 0.5 parts of neodymium oxide into the double-roller opener in sequence. Mixing in the mill, crushing after uniform mixing, and then adding the crushed rubber into the stirring tank, then adding 80.4 parts of mixed solvent, 0.1 part of A-Link 599 silane coupling agent, at 60 rpm Stir at a stirring speed for 4 hours until the glue is uniform and ready to be discharged.
Embodiment 3
[0043] According to the ratio of parts by mass, 10 parts of hydrogenated carboxylated nitrile rubber, 4 parts of fumed silica, 5 parts of epoxy-terminated liquid polysulfide rubber, 1 part of novolac epoxy resin, and 0.5 part of erbium oxide are added to the double-roller opening in sequence. Mixing in the mixer, crushing after uniform mixing, then adding the crushed rubber material into the stirring tank, adding 79 parts of mixed solvent, 0.5 part of A-Link 599 silane coupling agent, at 60 rpm Stir at a stirring speed for 5 hours until the glue is uniform and ready to be discharged.
