摘要

The present invention relates to a process for preparing silica-coated zinc oxide nanoparticles, a process for preparing the silica-coated zinc oxide-polymer resin matrix using the process, and more particularly to a process for preparing a silica-coated zinc oxide nanoparticle And a method and a manufacturing method of a silica-coated zinc oxide-polymer resin matrix using the same. According to the present invention, it is possible to prevent photocorrosion of nanoparticles and to exhibit an excellent photocatalytic activity inhibiting effect by coating the surface of zinc oxide nanoparticles with an appropriate thickness of silica. In addition, the silica-coated zinc oxide nanoparticles according to the present invention can exhibit not only excellent UV absorption but also visible light transmission function. According to the present invention, the dispersion ratio of the nanoparticles can be remarkably increased by melt-mixing the polymer resin into the silica-coated nanoparticles, and the pores present on the silica-coated surface of the nanoparticles can be blocked, Can be prevented from being degraded.
