Problems solved by technology

[0007] The main technical problem to be solved by the present invention is to provide a kind of bio-based diatom mud for the diatom mud coating currently on the market, in which a large amount of artificial synthetic additives are added, which makes the coating easy to produce harmful substances and endanger the environment and human health. The preparation method of the paint comprises pretreatment of bamboo chips to make bamboo chip powder, and calcining the powder in sections to make bamboo charcoal fiber; then ultrasonically extracting Coptis chinensis, Radix Astragali, and tea leaves, collecting filtrate and filter residue, and then making the filter residue Boil, then filter, combine the filtrates to obtain a mixed extract, then mix with bamboo charcoal fiber and add nano-diatomaceous earth, sepiolite powder, nano-activated carbon, shell powder, chitin, fish gelatin, and shake.

Abstract

The invention discloses a preparation method of a bio-based diatom mud coating, which belongs to the technical field of diatom mud coating preparation. In the present invention, bamboo chips are pretreated to make bamboo chip powder, and the powder is calcined in sections to make bamboo charcoal fiber; then Coptidis Rhizoma, Radix Astragali, and tea leaves are subjected to ultrasonic extraction, filtrate and filter residue are collected, and then the filter residue is boiled, and then Filtrate, combine the filtrates to obtain a mixed extract, then mix with bamboo charcoal fiber and add nano-diatomaceous earth, sepiolite powder, nano-activated carbon, shell powder, chitin, fish gelatin, and shake to obtain a bio-based Diatom mud coating. The invention is easy to operate, and the prepared diatom mud paint is natural and safe in raw materials without adding any artificially synthesized additives and will not produce harmful substances. The paint itself has a self-cleaning function, can be used for a long time, and has broad market prospects.

Description

technical field [0001] The invention discloses a bio-based diatom mud coating, which belongs to the technical field of diatom mud coating preparation. Background technique [0002] Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire retardant, self-cleaning of walls, sterilization and deodorization, etc. It is used to replace wallpaper and latex paint. It is suitable for interior wall decoration in villas, apartments, hotels, homes, hospitals, etc. Therefore, diatom mud coating is a new type of environmentally friendly coating. Diatom mud has the functions of eliminating formaldehyde and releasing negative oxygen ions. , calling it "breathable environmentally friendly functional wall material". [0003] The main raw material of diatom mud is diatomaceous earth, a diatom mineral formed by marine seaweed plant...
