Abstract

The present technology provides a urethane adhesive composition including a urethane prepolymer including an isocyanate group; an isocyanurate compound including an isocyanurate ring; and a terpene compound including an active hydrogen.

Claims (14)

1. A urethane adhesive composition comprising a urethane prepolymer comprising an isocyanate group; an isocyanurate compound comprising an isocyanurate ring; a terpene compound comprising an active hydrogen; and a monosulfide compound; wherein

the isocyanurate compound is an isocyanurate compound of an aliphatic diisocyanate; and

the urethane adhesive composition is a one-part adhesive composition.

2. The urethane adhesive composition according to claim 1 , wherein the isocyanurate compound of the aliphatic diisocyanate is an isocyanurate of pentamethylene diisocyanate.

3. The urethane adhesive composition according to claim 1 , wherein the active hydrogen is derived from a phenol compound.

4. The urethane adhesive composition according to claim 1 , wherein the terpene compound is a phenol modified product of an oligomer of monoterpene or hydrogenated monoterpene.

5. The urethane adhesive composition according to claim 1 , for a use of adhering a base material comprising an olefin resin.

6. The urethane adhesive composition according to claim 2 , wherein the active hydrogen is derived from a phenol compound.

7. The urethane adhesive composition according to claim 2 , wherein the terpene compound is a phenol modified product of an oligomer of monoterpene or hydrogenated monoterpene.

8. The urethane adhesive composition according to claim 3 , wherein the terpene compound is a phenol modified product of an oligomer of monoterpene or hydrogenated monoterpene.

9. The urethane adhesive composition according to claim 2 , for a use of adhering a base material comprising an olefin resin.

10. The urethane adhesive composition according to claim 3 , for a use of adhering a base material comprising an olefin resin.

11. The urethane adhesive composition according to claim 4 , for a use of adhering a base material comprising an olefin resin.

12. The urethane adhesive composition according to claim 1 , further comprising isocyanate silane.
