Abstract

The invention relates to diatom mud paint with a self-repairing function and a preparation method thereof and belongs to the field of preparation of diatom mud paint. The preparation method comprises(1) encapsulating dispersible latex powder as a core material through stearic acid as a capsule wall to obtain microcapsules, and (2) uniformly mixing the microcapsules and diatom mud powder accordingto a weight ratio of 1: 7 to 10 to obtain the diatom mud paint having a self-repairing function. After use of the diatom mud paint with a self-repairing function, when the diatom mud is cracked or damaged, the damaged position is heated so that the diatom mud is self-repaired and the repaired diatom mud paint has high bonding ability and unique water resistance. The diatom mud paint can repair cracks or breakage of diatom mud during use and can increase the waterproofness and scrub resistance of diatom mud.

Description

technical field [0001] The invention relates to a diatom mud coating with self-repairing function and a preparation method thereof, belonging to the field of diatom mud coating preparation. 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. walls), apartment, kindergarten, nursing home, hospital, nursing home, club, theme club, high-end hotel, resort hotel office building, style restaurant, etc. . 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 i...
