Provided is an annular adhesive synthesizing method. The method comprises the steps of: adding 40-60 parts of triallyl isocyanurate and 0.0015-0.0040 parts of platinum catalyst into a three-necked flask; at the 65-80 DEG C reaction temperature, slowly dropping 17-28 parts of 1,1,3,5,5-pentamethyl-3-phenyl trisiloxanes into the three-necked flask,and finishing the dropping within 0.5 hours; and stirring and reacting the mixture for 3-4 hours; adding 21-33 parts of trimethoxysilane into the three-necked flask and finishing the dropping within 0.5 hours; continuing the stirring and reaction for four hours; and then stopping the reaction; and removing low boiling materials by performing distillation at a reduced pressure. 6-9 parts of activated carbon are added into the substance, stirring and adsorbing are performed for 12 hours, and the annular adhesive is obtained after the material is filtered.
