METHOD FOR IMPROVING THE REFRACTIVE INDEX OF OPTICALLY CLEAR ACRYLIC PRESSURE-SENSITIVE ADHESIVE USING HAFNIUM CARBOXYETHYL ACRYLATE

摘要

The present invention relates to a manufacturing method for an ultraviolet (UV) curing optically clear acrylic adhesive with an improved refractive index including a hafnium carboxyl group and, more specifically, to a manufacturing method for a UV curing optically clear acrylic adhesive with an improved refractive index including a hafnium carboxyl group that copolymerizes 2-ethylhexyl acrylate, 2-phenoxyethyl acrylate and acrylic acid, and hardens ingredients with UV by mixing the ingredients with hafnium carboxyl ethyl acrylate. The manufacturing method for a UV curing optically clear acrylic adhesive comprises: a step of copolymerizing 2-ethylhexyl acrylate, 2-phenoxyethyl acrylate and acrylic acid with ethyl acetate, which is a solvent, under a presence of catalysts; a step of manufacturing a mixture by mixing the copolymers with hafnium carboxyl ethyl acrylate; and a step of irradiating the mixture with UV.
