Abstract: This invention provides a method of preparing high refractive spherical beads and in particular, there is provided a method of preparing high refractive spherical beads characterized in that they are prepared by preparing an inorganic composite material by adding an inorganic base compound having the refraction index of at least 1.5 to the inside of an inorganic material having porous or hollow air void and reacting them, coating the prepared inorganic composite material with a coating agent and drying the coated inorganic composite material. The high refractive spherical beads in accordance with the invention have excellent dispersion, light properties, UV stability, humidity resistance, thermal dimension stability, and weather resistance and in particular, they have superior heat resistance so that they can effectively prevent bending or yellowing resulting from UV irradiation, heat emission of lamps, heat generated from large-scale LCDs, etc. and they can be usefully applied to large-scale LCDs larger than 40 inches.

Abstract translation: 本发明提供一种制备高折射球形珠粒的方法，特别是提供一种制备高折射球状珠粒的方法，其特征在于它们是通过加入无机复合材料制备的，该无机复合材料的折射指数为 在具有多孔或中空空气空隙的无机材料的内部至少为1.5，并使它们反应，用制备的涂覆剂涂覆所制备的无机复合材料并干燥涂覆的无机复合材料。 根据本发明的高折射球形珠粒具有优异的分散性，光特性，UV稳定性，耐湿性，热尺寸稳定性和耐候性，特别是它们具有优异的耐热性，使得它们可以有效地防止由于 紫外线照射，灯的散热，大型LCD等产生的热量等，可以有效地应用于大于40英寸的大型LCD。
