PHOTOACTIVE COMPOSITION COMPRISING SCORIA AND PREPARATION METHOD THEREOF

摘要

Disclosed is a photoactive composition including 0.1-40 wt % of a photocatalyst in a powder or solution phase or a photocatalyst made of metal alkoxide; and 0.1-30 wt % of scoria powder, with the balance being a solvent, and a preparation method thereof. When interior coating is performed using the photoactive composition, activity can be exhibited even without the additional irradiation of light, and an organic material can be adsorbed and decomposed at high efficiency using only a very low light source through the combination of the adsorption performance of scoria and the decomposition performance of a photocatalyst. Because the photoactive composition is not in a powder phase but is in a liquid colloidal state, it can be efficiently employed as a coating agent enabling the surface coating treatment of any material and as an additive which is introduced into the preparation process of industrial materials or processed products.
