Problems solved by technology

However, most of the existing technologies are to use effective technical means to bond or fix the diatom ooze and photocatalyst components, causing the diatom ooze and photocatalyst components to easily fall off and lose, which greatly reduces the service life of the materials; Wrapped diatom mud and photocatalyst materials, reducing the adsorption effect

Abstract

The invention belongs to the field of ecological building materials, and provides a preparation method of a diatom ooze-artificial sandstone composite plate for ecological decoration. The preparationmethod has the advantages that diatom ooze and a photocatalyst are fixed to form a composite plate by utilizing the laser scanning, welding and foaming and the forming and curing of calcium carbonate,so that the falling of the diatom ooze and the photocatalyst is effectively prevented, and the porous adsorption characteristic of the diatom ooze and the contact area between the photocatalyst and air are better remained; when the diatom ooze-artificial sandstone composite plate is used for the internal decoration, the excellent respiration and humidity adjusting functions are realized, and theindoor heat insulation and isolation properties are realized; the photocatalyst can stably perform the photocatalytic reaction, the function of oxidizing and removing organic volatile matters in the air is realized, and the good function of killing bacteria and viruses exposed in the air is also realized.

Description

technical field [0001] The invention belongs to the field of ecological building materials, and in particular relates to an ecological decorative diatom mud-artificial sandstone composite board and a preparation method thereof. Background technique [0002] Eco-friendly, healthy and comfortable interior decoration materials have gradually become the main development trend of the building materials industry at home and abroad. The porous, fluffy, and stable chemical properties of diatomite make it have the properties of adsorption, heat insulation, and sound insulation. With other gelling components, color and particle adjustment components, a new type of wall material that is different from traditional coatings can be obtained. At present, there is a process of directly coating photocatalyst on the surface of artificial sand, which is easy to fall off, weakens the catalytic effect of photocatalyst, and has poor effect.
