SILICONE MATERIAL/CURING RESIN COMPOSITE AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To produce a silicone material/curing resin composite in which the adhesion and peeling resistance between the cured product of the curing resin and the silicone material are improved by curing an ultraviolet-curing resin layer formed on the surface of the silicone material by irradiating it with ultraviolet rays containing short-wavelength ultraviolet rays. SOLUTION: At least one ultraviolet-curing resin selected from among heat- curable acryl resins, heat-curable epoxy resins and heatcurable silicone resins is applied to the surface of a silicone material obtained by injection molding, compression molding, extrusion molding or the like to form a 500μm thick or thinner ultraviolet-curing resin layer 2 thereon. This layer 2 is cured by irradiating it with ultraviolet rays A containing powerful short-wavelength ultraviolet rays having a wavelength of about 185-250nm and ultraviolet rays having a wavelength of about 365nm to integrally bond the material 1 to the layer 2.
