Abstract

The invention provides a diatom ooze coating, belonging to the technical field of decoration coatings. Components of the diatom ooze coating mainly comprise synthesized emulsion, a dispersant, kieselguhr, a filler, a silver ion antibacterial agent, an additive and water and the like. The aperture of the selected kieselguhr is 280-580 meshes, and a micropore structure of the kieselguhr can be kept, and actions of humidifying and absorbing and dissolving formaldehyde can be achieved. The content of emulsion is reduced, and the strength of the coating after a wall is coated is ensured, and powder falling is avoided, and kieselguhr particles are not fully wrapped due to a formed membrane thus the micropores are not blocked, so that the functionality is not affected. The silver ion antibacterial agent is added into the coating, so the growth and propagation of microorganisms are effectively inhibited. The diatom ooze coating is obtained in a manner of charging materials in batches and stirring. Before the emulsion is added, under stirring, a thickener and a pH regulator are added, and the thickener can be fully dissolved by a shearing action, and an advanced dissolving step for the thickener is reduced.

Description

technical field [0001] The invention relates to the technical field of decorative coatings, in particular to a diatom mud coating and a preparation method thereof. Background technique [0002] Diatom mud is an environmentally friendly decorative wall material for interior walls with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, fire prevention and flame retardancy, sterilization and deodorization, etc. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, but also functional. It is a new generation of interior decoration materials that replace wallpaper and latex paint, and has a wide range of applications. It can be applied in the following places: family (living room, bedroom, study room, baby room, ceiling, etc. walls), apartment, kindergarten, nursing home, hospital, nursing home, club, theme club, high-end hotel, resort hotel, office building, style restaura...
