NOVELTY - Room temperature curing single component epoxy glue, where the single-component epoxy glue is ketimine as latent curing agent, comprises functionalized graphene oxide as the curing accelerator, prepared by using mechanical stirring and ultrasonic dispersion for uniformly dispersing ketimine and functionalized graphene oxide. USE - Used as room temperature curing single component epoxy glue. ADVANTAGE - The glue has high room temperature curing intensity, simple preparation, is environmentally friendly, and has economic value and social benefit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing room temperature curing single component epoxy glue comprising weighing 200 mg graphene oxide, adding into 200 ml 0.1 mol/l hydrochloric acid solution, carrying out ultrasonic treatment for 20-40 minutes to obtain the uniformly dispersed graphene oxide solution, under the action of ultrasonic, adding 160-240 ml 0.1 mol/l ferric chloride solution, slowly dripping into the prepared graphene oxide into hydrochloric acid solution, finishing dropping and continue ultrasound processing for 20-60 minutes to obtain green suspension, brown powdery solid of the suspension centrifugal, separating out orderly it with de-ionized water and ethanol to wash for 3 times, vacuum drying at 60 degrees C for 24 hours, to obtain iron ion doped graphene oxide, namely graphene oxide-iron (GO-Fe), weighing 200 mg GO-Fe, adding into 300 ml 0.1 mol/l hydrochloric acid solution, ultrasonic treatment for 30-60 minutes to obtain the uniformly dispersed GO-Fe hydrochloric acid solution under the ultrasonic effect, adding 200-300 ml 0.1 mol/l sodium dihydrogen phosphate solution slowly into the GO-Fe hydrochloric acid solution, after finishing dropping continuing ultrasound processing for 20-60 minutes to obtain brown suspension, brown powder solid suspension centrifuging, separating out orderly it with de-ionized water and ethanol to wash for 3 times, vacuum drying at 60 degrees C for 24 hours to obtain iron ion and dihydric phosphate radical ions co-doped graphene oxide, obtaining functionalized graphene oxide-iron-phosphate (GO-Fe-P), and (iii) weighing 80-220 mg GO-Fe-P, adding to 20 ml sample bottle, then adding 5 g latent curing agent ketimine into the sample bottle, ultrasonic processing for 4-8 hours, allowing to stand for 24 hours, then at 140-160 degrees C, stirring for 20-40 minutes, after allowing to stand and cooling, adding 10 g epoxy resin E-51, and continuously stirring for 1-3 hours at room temperature, removing air bubbles to obtain room temperature containing functionalized oxide graphene curing single component epoxy glue.
