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.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a modified siliceous lake mud building material and a preparation method. 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 coating began to be popular, but its high price made many consumers timid. Formaldehyde and other harmful gases are released for weeks or even decades after house decoration, seriously affecting people's lives and health. At present, there are common building materials such as deodorant latex paint, aldehyde removal latex paint, and diatom mud in the market. The deodorization and aldehyde removal mainly rely on their own reduction or no use of formalde...
