Abstract:
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.

Abstract:
PURPOSE: A method for preparing an adhesive sample is provided to rapidly estimate a result value according to each variable and to rapidly measure test results. CONSTITUTION: A method for preparing an adhesive sample is as follows. Adhesive is prepared(S11). The prepared adhesive is spread on a base material(S12). The gradients of one or more test variables are embodied in the spread adhesive(S13). The test variables are the thickness of the adhesive, the amount of irradiated ultraviolet rays, and the temperature of the adhesive.
