ACRYLIC PHOTO-CURING COMPOSITION FOR PREAPRING PRESSURE-SENSITIVE ADHESIVE AND ITS PREPARATORY METHOD

摘要

A composition for preparing a photocurable acrylic adhesive is provided to obtain a solvent-free pressure-sensitive adhesive via a simple photocuring process, and to realize excellent initial adhesion while maintaining other physical properties. A composition for preparing a photocurable acrylic adhesive comprises: 50-95 parts by weight of an acrylic copolymerized oligomer containing 2-ethylhexyl acrylate and n-butyl acrylate; and 0.05-2 parts by weight of a photoinitiator based on the acrylic copolymerized oligomer. The photoinitiator performs UV curing. The acrylic copolymerized oligomer has a viscosity of 500-10,000 centipoises. The acrylic copolymerized oligomer optionally further comprises 10 parts by weight or less of acrylic acid monomers.
