Composite film-coated self-cleaning inorganic ecological decorative plate and preparation method thereof

Abstract

The invention discloses a composite film-coated self-cleaning inorganic ecological decorative plate and a preparation method thereof.The preparation method comprises the following steps that 1, an inorganic ecological decorative plate is taken as a base body, and after the surface of the inorganic ecological decorative plate is subjected to dust blowing cleaning treatment, film coating loading is performed by adopting a photocatalytic hydrophilic coating through powder coating or spraying or a sol-gel method to obtain a TiO2-loaded inorganic ecological decorative plate; 2, the TiO2-loaded inorganic ecological decorative plate obtained in the step 1 is dried or subjected to ultraviolet curing, the drying temperature is 50 DEG C-85 DEG C, the drying time is 0.5-3 h, and after natural cooling is performed, the composite film-coated self-cleaning inorganic ecological decorative plate is obtained.Accordingly, the inorganic ecological decorative plate is taken as the base body, film coating loading is performed by adopting the photocatalytic hydrophilic coating through powder coating or spraying or the sol-gel method, moisture condensation is performed on kitchen and bath fumes, organic matter, sewage and dirt, outer curtain wall dust is self-removed, the self-cleaning capacity is high, and the durability is good.

Description

technical field [0001] The invention relates to the technical field of decorative building materials, in particular to a composite coating type self-cleaning inorganic ecological decorative board and a preparation method thereof. Background technique [0002] Since the discovery of irradiated TiO by Fujishima et al. in 1972 2 Since the continuous redox reaction occurs on the surface, photocatalytic technology has been shown to be the most effective way to degrade volatile harmful gases and organic pollution in indoor air. At the same time, it decomposes surface-attached microorganisms and super-hydrophilicity to reduce organic pollutants on the surface of building materials. of adhesion. [0003] Inorganic ecological decorative panels are represented by algal calcium decorative wall panels, algal calcium decorative ceilings, inorganic ecological wood, and inorganic ecological marble. Relying on the excellent plasticity and flexibility of inorganic cementitious materials, th...
