Abstract
Disclosed are a polyurethane adhesive composition having excellent adhesive performance and a method of preparing the composition. The polyurethane adhesive composition includes an ether-based compound containing an epoxide functional group a polyether carbonate polyol containing a carbonate bond so as to implement a carbon reduction effect. The polyurethane adhesive composition includes a admixture including (i) a polyether carbonate polyol containing a carbonate bond and (ii) an isocyanate compound, and an ether-based compound containing an epoxide functional group.
Claims18
A polyurethane adhesive composition comprising:
- an admixture comprising (i) a polyether carbonate polyol comprising a carbonate bond and (ii) an isocyanate compound;
- and
- an ether-based compound comprising an epoxide functional group,
- wherein a molar ratio of the polyether carbonate polyol to the other-based compound is about 1:3.4 to 3.6.
A method for preparing a polyurethane adhesive composition comprising:
- preparing an admixture comprising (i) a polyether carbonate polyol comprising a carbonate bond and (ii) an isocyanate compound;
- and
- obtaining a reaction product by reacting an ether-based compound comprising an epoxide functional group and the admixture,
- wherein a molar ratio of the polyether carbonate polyol to the ether-based compound is about 1:3.4 to 3.6.
