The aqueous adhesive composition has excellent adhesive strength. The aqueous adhesive composition provides adhesion property having polar and non-polar adherends, and the method for manufacturing such aqueous adhesive composition is provided.
Claims20
An aqueous adhesive composition comprising:
- emulsion polymer prepared by polymerizing a monomer mixture comprising vinyl-based monomers, (meth)acrylic acid-based monomers, (meth)acrylic acid ester-based monomers comprising C1-14 alkyl groups, and (meth)acryl ester-based monomers comprising hydroxyl groups;
- and
- a cyclic ether compound comprising two or more hydroxyl groups (—OH) and having a molecular weight of 75 to 200 g/mol.
A method for manufacturing an aqueous adhesive composition, comprising:
- mixing a monomer mixture comprising vinyl-based monomers, (meth)acrylic acid-based monomers, (meth)acrylic acid ester-based monomers comprising C1-14 alkyl groups, and (meth)acryl ester-based monomers comprising hydroxyl groups, an emulsifier and water to prepare a pre-emulsion;
- conducting emulsion polymerization of the monomer mixture in the pre-emulsion, in the presence of a polymerization initiator, to obtain an emulsion resin composition comprising emulsion polymer of the monomer mixture and water;
- and
- adding a cyclic ether compound comprising two or more hydroxyl groups (—OH) and having a molecular weight of 75 to 200 g/mol to the emulsion resin composition;
- and
- forming the aqueous adhesive composition having a mixture of the emulsion resin composition and the cyclic ether compound.
