A kind of modified silica lake mud building material and preparation method thereof

Abstract

The invention discloses a modified silicon soil lake mud building material and a preparation method thereof, and belongs to the technical field of building materials. The modified silicon soil lake mud building material provided by the invention comprises the following components: distilled water, modified silicon soil lake mud powder, injection activated carbon powder, a modified mineral water retention thickener, rutile nanometer titanium dioxide, a photocatalyst, heavy calcium carbonate powder, quicklime powder, a modified polyacylate emulsion, medical stone powder, hydroxypropyl methyl cellulose, pigment, and a nano-TiO2 modified chitosan antibacterial and antifungal agent. The modified silicon soil lake mud building material provided by the invention is prepared from green and environment-friendly materials through scientific compatibility, and is safe, stable, non-toxic and free of volatile harmful gases; the building material not only can adsorb and purify formaldehyde, benzene and other harmful gases, but also can adjust indoor humidity, enhance painting wall texture, realize sound insulation and heat preservation, eliminate odor, and realize inflaming retarding; the building material is also low in cost, free from cracking and dusting, antibacterial, antifungal, and easy to repair.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a modified silica 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 n...

AI Technical Summary

Problems solved by technology

However, the thickness of the film after construction is relatively thin, the content of diatomite with adsorption function is low, and the actual adsorption and purification functions are limited.

The added high-PVC latex is easy to block the pores of diatomite after forming a film, making it lose or reduce the adsorption capacity, thus losing the ability to remove aldehydes

And latex paint can't form strong sense of texture, can't satisfy the demand to individualized decoration; CN102633475B discloses " a kind of non-gel diatom mud building material " mentions to select diatomite, kaolin, bentonite, activated clay, wheat rice Natural materials such as stone powder, quartz sand, sepiolite and attapulgite clay, which are porous and have adsorption capacity, can maintain the porous structure of the above-mentioned natural materials because they are bonded and formed based on the characteristics of the above-mentioned natural materials without the use of chemical adhesives. With adsorption and moisture absorption properties, it can eliminate indoor pollution, adjust indoor humidity, eliminate peculiar smell, isolate noise, have a strong sense of texture on the surface of the coating, and have the effect of fire and flame retardant

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.
