Environment-friendly dry powder latex paint for interior wall and preparation method thereof

Abstract

The invention relates to an environmentally-friendly dry powder emulsion paint for an inner wall and a preparation method thereof. The environmentally-friendly dry powder emulsion paint for the inner wall is prepared through the following raw materials in parts by weight: 20-35 parts of white cement, 20-35 parts of calcium carbonate powder, 8-18 parts of ash calcium powder, 30-40 parts of modified degreased soybean powder pulp, 5-10 parts of titanium dioxide, 10-20 parts of propolis powder, 6-8 parts of water soluble glucan, 4-6 parts of flatting agent, 2-3 parts of organobentonite, 1-3 parts of nanometer magnetic ordered mesoporous medium, 2-3 parts of antioxidant, and 1-3 parts of additive, wherein the additive is at least one of flame-retardant powder, nanometer negative ion powder and an antistatic agent; the flatting agent is a liquid acrylic flatting agent. The environmentally-friendly dry powder emulsion paint for the inner wall is reasonable in raw material selection, and proper in matching; compared with an existing emulsion paint, the prepared dry powder emulsion paint has the advantages of being outstanding in water resistance, outstanding in bonding performance, high in consistency in the drying process, and high in flatness; in addition, the emulsion paint is high in stability during the drying process, is influenced slightly by the outside condition, and is hard to discolor; in addition, the emulsion paint is outstanding in antibacterial capacity, high in static resistance and high in fire retardance.

Description

technical field [0001] The invention relates to an environment-friendly dry powder latex paint for interior walls and a preparation method thereof, belonging to the technical field of building decoration materials. Background technique [0002] The solvent-based latex paint used in building decoration on the market is liquid, which is not convenient for packaging, transportation and storage. Storage and use of liquid latex paint requires a large number of plastic or iron storage barrels, which is costly, wastes resources, and pollutes the environment. [0003] In addition, the construction process of the current latex paint is complicated. First apply the putty powder about two times, then smooth the edges and corners with sandpaper, and then apply the primer at least once, and then the topcoat. The process is cumbersome, time-consuming and material-consuming. The cost is high. During the construction process, the coating is easily affected by the quality of putty powder, pr...

[0002] The solvent-based latex paint used in building decoration on the market is liquid, which is not convenient for packaging, transportation and storage. Storage and use of liquid latex paint requires a large number of plastic or iron storage barrels, which is costly, wastes resources, and pollutes the environment.

[0003] In addition, the construction process of the current latex paint is complicated. First apply the putty powder about two times, then smooth the edges and corners with sandpaper, and then apply the primer at least once, and then the topcoat. The process is cumbersome, time-consuming and material-consuming. The cost is high. During the construction process, the coating is easily affected by the quality of putty powder, primer or topcoat. If any quality is unstable, the coating will easily fall off or be uneven. In severe cases, it will fade and affect the appearance, requiring rework

[0004] The publication date is January 3, 2007. The Chinese invention patent with the publication number CN1887989A discloses an environmentally friendly dry powder coating and its preparation method. The permeability and crack resistance of this coating are not enough. When the wall produces fine cracks, Cracks will also appear in the coating; in addition, the coating contains diatomaceous earth, which has a porous particle structure, making the surface coating highly rough and not suitable for interior walls
