Problems solved by technology

[0004] However, at present, the price of diatom earth, the main raw material of diatom mud, is relatively high, which makes the price of diatom mud generally higher than that of other coatings, thus making the application of diatom mud very limited; Diatomite is mainly used, and the diatomite used to prepare diatom mud coatings is ordinary diatomite or diatomite; again, diatomite has the effect of adsorbing formaldehyde due to its developed pore structure, but it cannot Degradation of formaldehyde. Therefore, the diatom mud coating prepared by it does not have the performance of degrading formaldehyde. When the absorption of formaldehyde reaches saturation, it not only cannot absorb formaldehyde, but may also release formaldehyde, resulting in secondary pollution.
Finally, the current strength of diatom mud is poor, and it is easy to lose powder after a long time, which affects the appearance of diatom mud coating

Abstract

The invention provides a diatom ooze coating capable of degrading formaldehyde and a preparation method of the diatom ooze coating. The diatom ooze coating comprises a main component of low-grade kieselguhr, and after steps of pore forming and roasting, the kieselguhr is mixed with other raw materials to prepare the diatom ooze coating capable of degrading formaldehyde. The diatom ooze coating iscapable of not only absorbing formaldehyde, but also degrading formaldehyde, and meanwhile has the advantages of being high in strength, good in durability, capable of releasing anion, low in cost, and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to diatom mud coatings. Background technique [0002] Diatom mud is a natural and environmentally friendly interior wall decoration material, which is used to replace wallpaper and latex paint, and plays the role of interior wall decoration and indoor air purification. Powder packaging, not liquid barrels. Diatom mud has a wide range of applications. It can be applied in the following places: family (living room, bedroom, study room, baby room, ceiling, etc.), apartment, kindergarten, nursing home, hospital, nursing home, club, theme club, high-end hotel, resort hotel office building, style restaurant, etc. . [0003] The main raw material of diatom mud is diatom earth, a diatom mineral that has been formed for hundreds of millions of years. Diatom is a kind of algae that lives in oceans and lakes. Diatom mud is a natural substance deposited by aquatic plankton living millions ...
