Abstract

The invention relates to an inner wall paint with a low viscosity, a strong covering performance, and a strong scrubbing resistant performance. The inner wall paint is prepared from the following components: water, hydroxyethyl cellulose, inorganic thixotropic thickening agent, bentonite, aqueous multifunctional aid, dispersant, wetting agent, diatomite, titanium dioxide, 800-mesh heavy calcium carbonate, talcum powder, calcined kaolin, emulsion, antifreeze agent, film forming aid, antifoaming agent, thickening agent, and antiseptic anti-mildew agent. The provided paint has the same covering performance as that of high grade paint, the contrast ratio is more than 0.95, and the scrubbing resistant performance is strong. The paint can be applied to primary painting without being diluted by water. The paint only needs once roller painting in decoration or rebuilding. The construction frequency is reduced. The paint film has an excellent performance, and the hand feeling is good. The labor cost is saved, the construction time is reduced, the transportation cost is reduced, and the paint can be well stored under the condition of low viscosity.

Description

technical field [0001] The invention relates to the field of decorative coatings, in particular to a low-viscosity, high-covering and high-scrub-resistant interior wall coating and a preparation method thereof. Background technique [0002] In consideration of storage stability, the viscosity of interior wall paints is usually around 100-120ku, because low-viscosity paints often lead to layering and sedimentation during storage. However, the optimum viscosity for construction is generally 75-85ku, so 30%-50% of water is usually added during normal construction. Adding water will seriously reduce the hiding power and scrub resistance of the coating and other properties. Therefore, using the current interior wall paint, the normal construction process is one coat of primer plus two coats of finish paint to ensure the covering property of the construction and the strength of the paint film. Contents of the invention [0003] The invention provides a low-viscosity, high-cove...
