Potato modified starch composite multifunctional diatom mud wall decoration material

Abstract

Disclosed is a production preparation method for a potato modified starch composite multifunctional diatom mud wall decoration material comprising the following components by the weight percentage: 30-70% of diatomite, 3-10% of nano titanium dioxide, 10-25% of organic white bentonite, 5-15% of a dispersible latex powder, 1-3% of hydroxypropyl methyl cellulose, 10-35% of potato modified starch, and 0.1-0.5% of a mildew preventive. The multifunctional diatom mud wall decoration material is prepared by evenly stirring of the raw materials with a sealed drum stirrer. The product is a powder; when in use, the product only need to be mixed with water into a paste and can be applied by a spraying, roller-coating or scraping way. The product adopts more natural environmental-protection materials as raw materials, especially with combination of an adhesive, the cost is low, and the material is easy to obtain. Formaldehyde can be really effectively eliminated, the odor in air can be really effectively purified, harmful gases in a house can really effectively adsorbed and decomposed, and the troubles brought by ] formaldehyde and other VOCs harmful substances in modern building decoration can be effectively solved.

Description

technical field [0001] The invention relates to the field of diatom mud wall decoration material formulations, in particular to a preparation method of a multifunctional diatom mud wall decoration material compounded with modified potato starch. Background technique [0002] At present, with the rapid development of my country's economy, people's awareness of physical health is constantly increasing. Therefore, while demanding aesthetics and decoration, more attention is paid to functionality, naturalness, environmental protection, and original ecology. At the same time, the current decoration material products, including furniture, contain more or less harmful VOC substances, which seriously affect people's physical and mental health. The release of harmful substances, it is an invisible killer of our health. Cases of carcinogenicity caused by formaldehyde are not uncommon in real life. Now the wall decoration materials on the market can no longer simply meet people's needs...

AI Technical Summary

Problems solved by technology

Some materials that can decompose the adsorbed harmful gases are not used, which eventually leads to poor product functions, cannot be recycled, and cannot absorb and decompose harmful substances.
