Abstract

The invention discloses a potassium silicate compound finished product diatom ooze which comprises the following components in parts by weight: 20-35 parts of deionized water, 0.1-1 part of a wetting agent, 0.3-1.2 parts of a dispersing agent, 0.2-1 part of an antifoaming agent, 0.8-3 parts of propylene glycol, 0.5-1.0 part of hydroxyethyl cellulose, 5-20 parts of coarse whiting powder, 3-10 parts of titanium dioxide, 30-50 parts of kieselguhr, 0.5-1.5 parts of a photocatalyst, 1-10 parts of anion powder, 8-20 parts of potassium silicate, 2-8 parts of styrene-acrylic emulsion and 0.1-2 parts of a stabilizing agent. According to the potassium silicate compound finished product diatom ooze disclosed by the invention, by adding potassium silicate with strong alkalinity as a main film forming matter, the potassium silicate with strong alkalinity can inhibit the growth of microorganisms, so that the coating has excellent mildew resistance; by adopting the potassium silicate compound organic emulsion and adding the wetting agent and the potassium silicate stabilizing agent, the finished product diatom ooze has good stability, and the product can not be hardened or can not sink to the bottom and separate from water and has no peculiar smell; the diatom ooze coating is in a finished product state, can be immediately used after the tank is opened, and is convenient in construction; and colors can be adjusted optionally according to client requirements, thereby meeting multiple demands of clients.

Description

technical field [0001] The invention belongs to the field of environment-friendly materials for high-grade household decoration, and in particular relates to diatom mud in a finished state made of potassium silicate compound organic matter and a preparation method thereof. Background technique [0002] Diatom mud is an environmentally friendly decorative material for interior walls with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire and flame retardant, self-cleaning walls, sterilization and deodorization, etc. Because diatom mud not only has the advantages of health and environmental protection, but also has good decorative and functional properties, it has been widely used in recent years and is a new generation of interior decoration materials that can replace wallpaper and latex paint. [0003] Although some exterior wall coatings on the market use silicate alon...
