Problems solved by technology

Compared with traditional latex coatings, its stain resistance has indeed improved to a certain extent, but in high "pollution" environments, especially kitchens with high oil fumes, the walls are easily stained by oil stains, even this type of "strong stain resistance" Paint, after wiping off the oil fume stained on the surface, will still leave very obvious traces, and the degree of stain resistance is limited
In addition, the kitchen is a humid and watery place. The coating film formed by one-component latex paint is generally dense and low in hardness. After being wiped with water for a long time, the coating film is prone to mildew, damage, blistering and even peeling off

Abstract

This invention relates to the field of coatings. A coating for interior walls comprises an A component and a B component, wherein a weight ratio of the A component to the B component is 1:1; the A component comprises the following materials: 20-45 parts of deionized water, 0.1-1 part of a thickening agent, 0.5-2 parts of a high-molecular dispersant, 0.1-1 part of a wetting agent, 0.2-1.5 parts ofa defoaming agent, 20-40 parts of titanium dioxide, 5-10 parts of talc powder, 0.1-1 part of bentonite, 14-22 parts of a water-based curing agent, 0.1-1 part of a levelling auxiliary agent, 0.1-1 partof a preservative, and 0.1-1 part of an anti-mold agent; and the B component comprises the following materials: 1-38 parts of deionized water, 60-96 parts of a water-based epoxy emulsion, 0.1-2 partsof an anti-freezing agent, and 0.1-1 part of a preservative. The waterproof stain-resistant water-based coating for the interior wall provided by the invention is a two-component coating, has the characteristics of high compactness and strong stain resistance, and is particularly suitable for use in home environments such as kitchens of which walls are easily stained by oil fume.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof and stain-resistant interior wall coating for kitchens and a preparation method thereof. Background technique [0002] At present, latex paint is still the first choice for interior wall decoration, while traditional latex paint has poor stain resistance and waterproof performance. With the continuous advancement of emulsion synthesis technology and the gradual openness and transparency of latex paint formulations, the performance of latex paint has been greatly improved, and many one-component latex paints featuring "strong stain resistance" have appeared on the market. Compared with traditional latex coatings, its stain resistance has indeed improved to a certain extent, but in high "pollution" environments, especially kitchens with high oil fumes, the walls are easily stained by oil stains, even this type of "strong stain resistance" Paint, after wiping off the oil fume s...
