Modified diatomite lake mud building material for interior wall decoration and preparation method

Abstract

The invention discloses a modified diatomite lake mud building material for interior wall decoration and a preparation method, and belongs to the technical field of building materials. The building material comprises distilled water, modified diatomite lake mud powder, activated shell powder, modified mineral water-holding densifier, anatase nano titanium dioxide, modified kaolin powder, ground calcium carbonate, quicklime powder, modified acrylate emulsion, granodiorite powder, hydroxyethyl methylcellulose, pigment and nano-TiO2 modified chitosan antibacterial mildew preventive. The building material is formed through scientific compatibility of green and environment-friendly materials, is safe, stable, poisonless and free from volatile harmful gases, can adsorb and purify the harmful gases such as formaldehyde and benzene, regulate indoor humidify, enhance textures of coated wall surfaces, insulate sound and heat, remove peculiar smell, prevent fire and retard inflaming, and also has the advantages of low cost, non-existence of cracking and peeling, bacterium resistance, mildew prevention, easiness in repair and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a modified silica lake mud building material used for interior wall decoration and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the personalization of decoration and the environmental protection of materials. In the past, the combination of putty powder and latex paint used to decorate interior walls can no longer meet people's needs. Diatom mud paint has become popular, but its high price has discouraged many consumers. The release of formaldehyde and other harmful gases after house decoration lasts for weeks or even decades, seriously affecting people's lives and health. At present, building materials such as deodorizing latex paint, aldehyde-removing latex paint, and diatom mud are common in the market. The deodorization and aldehyde remova...

AI Technical Summary

Problems solved by technology

Due to the use of the above-mentioned many ore powders without proper use of binders, after drying and weathering, the coatings that are easy to dehydrate and become hardened tend to lose their bonding effect with the wall, and problems such as cracking, falling off, and powder falling of the coating are prone to occur. Dust and other secondary pollution

However, the above-mentioned patent only uses diatomite and sepiolite with adsorption function, but does not use materials with catalytic and decomposition functions, so after its adsorption is saturated, its coating becomes a potential pollutant

Moreover, its high price has discouraged many consumers, which has ultimately led to its failure to popularize and promote.
