Problems solved by technology

[0003] At present, most diatom mud wall materials on the market use nano-titanium dioxide as a photocatalyst to catalyze and decompose harmful substances adsorbed under light conditions. However, titanium dioxide has low photocatalytic efficiency and can only exert light under ultraviolet light. Catalysis, poor spectral response to visible light, poor adsorption of harmful substances and other shortcomings, resulting in diatom mud wall materials can not guarantee the air purification effect, so most of these diatom mud wall materials can only achieve partial adsorption of harmful substances. Substances, weak ability to decompose harmful substances, weak antibacterial ability, unsatisfactory automatic humidity control ability, difficult to meet people's urgent needs for long-lasting and efficient adsorption and decomposition of harmful substances such as formaldehyde

Description

technical field [0001] The invention relates to a novel decorative and functional interior decoration material with diatomite as the main raw material, in particular to a high-efficiency air-purifying / antibacterial / automatic humidity-regulating diatom mud wall material and its preparation method. Background technique [0002] Traditional home decoration wall materials are mainly divided into two types: lacquer and wallpaper. These two types of wall materials have varying degrees of VOC emissions during use, which seriously threatens people's health. With social development and economic progress, people pay more attention to the health, comfort, environmental protection, aesthetics and other functions of interior decoration wall materials. Diatomite has many excellent properties such as low density, large specific surface area, high porosity, strong liquid adsorption capacity, high chemical stability, high melting point, soft quality, sound insulation, wear resistance, heat r...
