Abstract

The invention discloses a preparation method of a diatom ooze coating, and belongs to the field of interior decoration coatings. The method comprises the steps of adopting a prepolymer generated through reaction of dimethylolpropionic acid and isocyanate as a hydrophilic group, introducing onto a nitrocellulose molecule, and self-emulsifying for synthesizing a water-based nitrocellulose emulsion;then blending an acrylic acid and hydroxyethyl acrylate copolymerization product and the water-based nitrocellulose emulsion to obtain an acrylic resin blending modification water-based nitrocelluloseemulsion; adopting acrylic acid and hydroxyethyl acrylate for copolymerizing to obtain a copolymerization product containing hydroxy and carboxyl; using cross-linking reaction for bringing the copolymerization product onto nitrocellulose, and synthesizing an acrylic resin graft copolymerization and modification water-based nitrocellulose emulsion. The preparation method of the diatom ooze coatingprovided by the invention solves the problems that a current diatom ooze coating is better in environmental performance but poor in adhesive property and intolerant to scrub, is poor in water resistance, cannot be used in a wet environment, and has no remarkable humidifying effect.

Description

technical field [0001] The invention belongs to the field of interior decoration coatings, and in particular relates to a preparation method of diatom mud coatings. Background technique [0002] Diatom mud coating is a powder coating made of diatomite as the main raw material and various additives. Diatom mud is a kind of interior wall environmental protection decorative wall material with diatomite as the main raw material. Diatomite is a kind of siliceous rock, which is formed from the silicate remains after the death of single-celled algae collectively known as diatoms. The main component is silicon dioxide, which is shown as a micron-scale porous material under the electron microscope, with a porosity of 90%, and the number of micropores per unit area is thousands of times more than that of charcoal. Because of the properties of diatomite, diatom mud has good functions of absorbing formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire ret...
