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.

Abstract

The invention discloses a modified argillaceous lake mud construction material and a preparation method, and belongs to the technical field of construction materials. The construction material comprises distilled water, modified argillaceous lake mud powder, a modified mineral water retention thickener, hydrophilic nanometer titanium dioxide, a photocatalyst, talcum powder, a modified polyacylate emulsion, medical stone powder, hydroxyethyl methyl cellulose, pigment and a nanometer TiO2 modified chitosan antibacterial and antifungal agent. The construction material is prepared by scientific compatibility of environmental-friendly materials, and the construction material is safe, stable, and free of toxicity and volatile harmful gas. Moreover, the construction material not only can adsorb and purify formaldehyde, benzene and other harmful gas, but also can adjust indoor humidity, enhance finishing metope texture, achieve sound insulation and heat preservation, eliminate peculiar smells, and achieve fire prevention and fire resistance. The construction material also has the advantages of being low in cost, free of cracking and dusting, antibacterial, antifungal, and easy to repair and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a modified clay lake mud building material 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 removal mainly rely on methods such as reducing or not...
