A sealant syringe assembly comprising: a first syringe for discharging a first solution; a reaction solution syringe for discharging a reaction solution capable of reacting with the first solution; a base on which the first syringe and the reaction solution syringe are seated; and a connector for connecting the first syringe and the reaction solution syringe to mix and discharge the first solution and the reaction solution, such that the first solution reacts with the reaction solution to cause change in properties such that a shear storage modulus exceeds a shear loss modulus, wherein the first syringe includes: three or more packing members (11, 12, 13) provided inside the first syringe; chambers (15, 16) defined by adjacent packing members of the three or more packing members (11, 12, 13), wherein a buffer solution is provided in one of the chambers (15, 16), and a first compound powder is provided in another chamber (15, 16); a passage provided in an inner circumferential surface of the first syringe; and a plunger for providing pressure to one of the packing members (11, 12, 13), and wherein the reaction solution syringe includes: at least two packing members (21, 21', 22, 23, 23') provided inside the reaction solution syringe; at least one chamber (25, 26) defined by adjacent packing members of the at least two packing members (21, 21', 22, 23, 23'); and a plunger for providing pressure to one of the packing members (21, 21', 22, 23, 23'), characterized by a first packing member of the packing members (11, 12, 13) of the first syringe being disposed near the connector, and a fourth packing member of the packing members (21, 21', 22, 23, 23') of the reaction solution syringe being disposed near the connector, and wherein the first packing member and the fourth packing member, respectively, block movement of the first solution and the reaction solution to ensure that the first solution and the reaction solution can be discharged to the connector simultaneously. a first syringe for discharging a first solution;
