The invention provides a self-remedied super adhesive and a preparation method thereof. The self-remedied super adhesive provided by the invention is excellent in physical mechanical property due to a boroxol hexatomic ring cross-linking structure, the Young modulus is as high as about 180MPa, moreover due to the boroxol hexatomic ring in the structure, corresponding boric acid can be formed after the boroxol hexatomic ring is damaged, and furthermore through a dehydration function, the boroxol hexatomic ring can be formed again, so that an excellent self-remediation property can be achieved, the adhesive can be reused after being peeled, and the adhesion strength of the adhesive can be as high as 7.5MPa after the adhesive is cured for 24 hours at the curing temperature of 70 DEG C; and after remediation for 24 hours at 70 DEG C, the adhesion strength of the super adhesive is still as high as 5.7MPa, so that the adhesive force level of a commercial super adhesive such as an epoxy super adhesive or a cyano-acr
