Abstract

The invention discloses an environment-friendly interior wall coating without floating during application and a preparation method thereof, and the environment-friendly interior wall coating comprises the following components in percentage by mass: 21.2-37.8% of water, 0.2-0.7% of a powdery thickening agent, 0.1-0.4% of a bactericide, 0.4-0.8% of a dispersing agent, 0.1-0.4% of a wetting agent, 0.2-0.7% of a defoaming agent, 0.1-0.3% of a pH value regulator, 2-20% of titanium dioxide, 3-12% of kaolin, 10-32% of heavy calcium powder, 1-5% of a functional filler, 0.2-0.6% of a functional additive A and 0.5-2.5% of a functional additive B, the coating comprises the following components in percentage by weight: 8-38% of an acrylate emulsion, 0.2-0.7% of a thickening agent A and 0.2-0.7% of a thickening agent B. According to the invention, the freeze-thaw resisting agent, the odor-removing emulsion and KOH are added to replace ethylene glycol, propylene glycol, inorganic ammonia or organic ammonia and a coalescing agent in a traditional formula, so that the content and odor of volatile organic compounds in the coating are reduced; the powdery thickening agent, the sericite and the sodium bentonite form a layered structure, so that the water-retaining property of the coating is improved, the drying time of a paint film is prolonged, so that the paint film has enough time to be uniformly rolled and brushed to reduce the floating phenomenon, and the freeze-thaw resistant agent prolongs the drying time of the paint film and further prolongs the drying time of the paint film to reduce the floating phenomenon.

Description

technical field [0001] The invention relates to the technical field of interior wall paints, in particular to an environment-friendly interior wall paint that is applied without blooming and a preparation method thereof. Background technique [0002] Latex paint is a paint made of synthetic resin emulsion as film-forming material, water as solvent, adding pigments, fillers and additives, and through a certain process. It has the advantages of safety, hygiene and environmental protection, and has air permeability and alkali resistance. Well, secondly, it has more varieties and bright colors, so it is widely used in the interior and exterior wall decoration of buildings. [0003] In the process of using latex paint, it is generally brushed on the wall manually, and the paint is formed into a film by reciprocating rollers on the wall until the coating is evenly formed and does not flower. However, when the existing latex paint is used, Due to the problem of the paint formulati...
