Glass bead load modified Nano-Tio2 photocatalyst, application thereof to formaldehyde removal magnesium oxide board and formaldehyde removal magnesium oxide board

The invention discloses a glass bead modified Nano-Tio2 photocatalyst, application thereof to a formaldehyde removal magnesium oxide board and the formaldehyde removal magnesium oxide board. The photocatalyst is obtained by dispersing, dewatering and dying from a nanometer titania aqueous solution, a surfactant, a dispersant and glass beads in an appropriate ratio. By applying the photocatalyst to the preparation of formaldehyde removal magnesium oxide board, the magnesium oxide board obtained has the effect of enduringly purifying formaldehyde, and has the advantages of good thermo insulating property and good screw holding capability, without moisture absorption, active magnesia and buckling deformation. 本发明公开了种玻璃微珠负载改性Nano-TiO光催化物及其在除醛玻镁板中的应用和除醛玻镁板。所述玻璃微珠负载改性Nano-TiO光催化物采用适当比例的纳米二氧化钛水溶液、表面活性剂、分散剂、玻璃微珠经分散脱水干燥得到，将所述光催化物应用于制备除醛玻镁板，所得玻镁板具有持久净化甲醛作用，具有保温隔热性佳，握螺钉力好，不吸潮返卤，不翘曲变形等优点。
