High-hardness easily-scrubbed interior wall coating for kitchen and preparation method

Abstract

The invention discloses a high-hardness easily-scrubbed interior wall coating for a kitchen and a preparation method. The coating comprises, in weight percentage, 14-24% of water, 0.4-0.6% of wetting dispersants, 0.2-0.25% of cellulose, 0.1-0.2% of defoaming agents, 0.8-1.2% of anti-freezing agents, 0.3-0.6% of scratch-resistant agents, 0-10% of titanium dioxide, 20-30% of calcite in powder, 0.1-0.2% of pH (potential of hydrogen) conditioning agents, 40-50% of silane-siloxane emulsion, 2-2.5% of coalescing agents, 0.5-1% of mildew-proof agents, 0.1-0.3% of sterilizing agents, 0.2-0.4% of water repellent agents and 0.2-0.3% of anti-doodling agents. According to the emulsion, reactivity and permeability of silane and flowability and water drop effect of siloxane can be combined, molecular volume is minimum, the surfaces of substrates are coated with the emulsion, the emulsion can deeply permeate into the substrates, and reaction between the emulsion and the substrates and between the emulsion can be achieved, so that durability is achieved. After emulsion is cured, permeation of water vapor is allowed, liquid water possibly containing chloride ions or acid after dissolution is prevented from permeating into the substrates, condensation reaction between silane can be achieved to form Si-O-Si polymers, the silane facing the outer side of the surface can effectively drain water, and protection for freezing and thawing damage, permeation, oil penetration and mildew can be provided.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to high-hardness and easy-to-clean interior wall coatings for kitchens and a preparation method thereof. Background technique [0002] Kitchen coatings have very high requirements for coatings due to the particularity of the kitchen, such as darkness, humidity, and oil stains. It must not only meet the requirements of moisture-proof and mildew-proof, but also meet the requirements of easy removal of oil stains. When decorating the kitchen, some users choose ordinary interior wall paint to decorate the kitchen. There are also some users who choose ceramic tiles or wallpapers, because the kitchen is prone to oil stains that condense on the walls, and the oil stains on tiles and wallpapers are easier to remove. [0003] This just causes existing products on the market to have following shortcoming: [0004] Choose ordinary interior wall paint: Since ordinary interior wall paint has...

AI Technical Summary

Problems solved by technology

[0005] Sticking ceramic tiles: The kitchen is located on the shaded side of the building, so it is unavoidable to avoid moisture and mildew. After a period of time, under the action of moisture, the ceramic tiles or wallpapers are easy to fall off from the wall surface; A large amount of adhesive is used, which is highly toxic; it needs to be repaired or replaced frequently after falling off or damaged;

[0006] The scrub resistance of some special kitchen coatings does not meet the actual use requirements. After scrubbing with a damp cloth, powder will fall off or the paint film will be damaged, which is prone to mold
