3. The polyurethane resin composition according to claim 2, wherein the bis (trialkoxysilylpropyl) amine is one or more selected from the group consisting of bis (trimethoxysilylpropyl) amine, bis (triethoxysilylpropyl) amine, and bis (tripropoxysilylpropyl) amine.

4. The polyurethane resin composition as claimed in claim 1, wherein the isocyanate bonded to the biuret body includes one or more selected from the group consisting of hexamethylene diisocyanate, cyclopentylene-1, 3-diisocyanate, cyclohexylene-1, 2-diisocyanate, hexahydroxylylene diisocyanate, dicyclohexyl-4, 4-diisocyanate, 1-methyl-2, 4-diisocyanatocyclohexane, 1-methyl-2, 6-diisocyanatocyclohexane, bis (4-isocyanatocyclohexyl) methane, 1, 4-diisocyanatocyclohexane and 1, 3-diisocyanatocyclohexane.

5. The polyurethane resin composition as claimed in claim 1, wherein the biuret body is 1,3, 5-tris (6-isocyanatohexyl) biuret.

6. The polyurethane resin composition according to claim 1, wherein a second plasticizer is added to the reaction to obtain the binder resin.

7. The polyurethane resin composition according to claim 1, further comprising one or more selected from the group consisting of a pigment, a catalyst and an adhesion promoter.

8. The polyurethane resin composition according to claim 7, wherein the catalyst is one or more selected from the group consisting of dimethyltin dioleate, dibutyltin dimaleate, dibutyltin dilaurate, dibutyltin diacetate, dibutyltin octanoate, dibutyltin mercaptide, dioctyltin dilaurate, dioctyltin mercaptide, dioctyltin dimaleate, 4' - (di-2, 1-ethanediyl oxide) dimorpholine, and dimethyl-4-morpholinoethylamine.

9. The polyurethane resin composition as claimed in claim 7, comprising, based on 100 parts by weight of the polyurethane resin composition

25 to 70 parts by weight of the urethane resin;

9 to 20 parts by weight of the binder resin;

3 to 15 parts by weight of the first plasticizer;

20to 35 parts by weight of the pigment;
