Described amino-terminated poly-pyrrole throat prepolymer is prepared from by following methods:
The there-necked flask being completely dried adds the Isosorbide-5-Nitrae of 0.95 mole, 5, the metacresol of 8-naphthalenetetracarbacidic acidic dianhydride and 1000mL, stir under nitrogen protection, after dianhydride is completely dissolved, add the 3 of 1 mole, 3 '-diaminobenzidine, at room temperature after stirring 30min, heating, to 75 DEG C, reacts 3.5h, again at 185 DEG C, react 4.5h; Reaction is down to room temperature, solution is poured in methanol, has Precipitation after terminating; After filtering after removing solvent with methanol cyclic washing, in vacuum drying oven, at 50 DEG C, dry 24h, to obtain final product.
In one embodiment, described anti-corrosive antibacterial epoxy sealing glue, wherein, described B component glue also includes the amino-terminated hyperbranched polybenzimidazoles of 10 weight portions, and described amino-terminated hyperbranched polybenzimidazoles is prepared from by following methods:
By 0.2 mole 3,3 '-diaminobenzidine is first dissolved in 1000 grams of polyphosphoric acids containing 85wt% phosphorus pentoxide, then by the 1,3 of 0.07 mole, between 5-, benzenetricarboxylic acid joins in reactant liquor, after reacting 15 hours at 220 DEG C, being down to room temperature, precipitating is in water, then neutralize with ammonia, filter, vacuum drying at 100 DEG C, obtain amino-terminated hyperbranched polybenzimidazoles.
The preparation method that another aspect of the present invention provides anti-corrosive antibacterial epoxy sealing glue, including:
The composition of described component A glue is mixed at 50 DEG C, with the speed mechanical dispersed with stirring 30 minutes of 1000 revs/min, obtains component A glue;
