Composition for adhesion of dissimilar materials, and preparation method therefor

Abstract

The present invention relates to a composition for adhesion of dissimilar materials, and a preparation method therefor, and, more specifically, to a composition for adhesion of dissimilar materials, and a preparation method therefor, the composition comprising, in a specific weight ratio, a (meth)acrylic monomer, an epoxy resin, an epoxy curing accelerator, a thermal polymerization initiator, a polymerization inhibitor and a (meth)acrylic-modified polyurethane component, which comprises a hydrophilic (meth)acrylic-modified polyurethane and a lipophilic (meth)acrylic-modified polyurethane, and having excellent oil resistance while enabling high adhesiveness to be implemented between dissimilar materials at room temperature and high temperatures.
