Problems solved by technology

[0003] Architectural coatings that not only have decorative effects but also do not pollute the air environment are traditionally prepared by adding formaldehyde-removing reagents and decorative reagents. However, the above-mentioned formaldehyde-removing reagents are generally prepared by powder with adsorption. The problem of poor adsorption effect and poor compatibility with other additives or additives. In addition, the general preparation method is relatively complicated, and it is difficult to balance the effect of coating texture and environmental protection.

Embodiment 1

[0017] A formaldehyde-decomposable water-based metallic matte paint for interior walls, which consists of the following components, in terms of mass percentage: 28-32% water, 98% diatomite of 1250 mesh, and 2% biological enzymes and photocatalysts The combination of aldehyde removal powder 3-10%, aldehyde removal acrylic emulsion 45-55%, inorganic pearlescent pigment 5-8%, propylene glycol antifreeze agent 2-3%, wetting agent 0.2%, dispersant 0.3-0.5%, mineral oil 0.2% defoamer, 0.3% hydroxyethyl cellulose, 0.2% mineral oil defoamer, 0.1% pH regulator, 0.2% preservative, 2-3% film-forming aid, 0.3-0.5 alkali swelling thickener %, associative thickener 0.2-0.4%.

Embodiment 2

[0019] A method for preparing a formaldehyde-decomposable water-based metal matte paint for interior walls, specifically adopting the following steps: first mix 20g of water, cellulose thickener, dispersant, antifreeze, 1 / 2 defoamer, moisturizer Wet agent, preservative, and pH adjuster are added to the dispersing tank, and stirred at 300-400rpm, then add combined aldehyde-removing powder, inorganic pearl powder, disperse at 600-800rpm for 20min, and then add the remaining water And the remaining defoamer, then add 46g of aldehyde-removing acrylic emulsion, add 1 / 2 defoamer at 100-300rpm, disperse at a low speed of 100-300rpm for 10min until the system has no bubbles, and finally add thickener to adjust to a suitable viscosity. The mass percent of each component in this embodiment is: 46% of aldehyde-removing acrylic acid emulsion, 10% of combined aldehyde-removing powder, 8% of inorganic pearl powder, 6% of various additives, and 30% of water.

Embodiment 3

[0021] A method for preparing a formaldehyde-decomposable water-based metal matte paint for interior walls, specifically adopting the following steps: first mix 20g of water, cellulose thickener, dispersant, antifreeze, 1 / 2 defoamer, moisturizer Wet agent, preservative, and pH adjuster are added to the dispersing tank, and stirred at 300-400rpm, then add combined aldehyde-removing powder, inorganic pearl powder, disperse at 600-800rpm for 20min, and then add the remaining water and the remaining defoamer, then add 55g of aldehyde-removing acrylic emulsion, add 1 / 2 defoamer at 100-300rpm, disperse at a low speed of 100-300rpm for 10min until the system has no bubbles, and finally add a thickener to adjust to a suitable viscosity. The mass percent of each component in the present embodiment is: 55% of aldehyde-removing acrylic acid emulsion, 3% of combined aldehyde-removing powder, 5% of inorganic pearl powder, 8% of various additives, and 29% of water.

Abstract

The invention discloses an interior wall-oriented water-based metal matte paint capable of decomposing formaldehyde and a preparation method thereof. According to the paint, a formaldehyde degrading functional powder and an acrylic polymer with a formaldehyde degrading effect are taken as main formaldehyde degrading components; an inorganic pearl powder is added to ensure that the paint has a metal paint texture and a water-based texture; and the paint is capable of decomposing free formaldehyde in indoor air so as to achieve the aim of purifying the indoor air.

Description

technical field [0001] The invention relates to a formaldehyde-decomposable water-based metal matt paint for interior walls and a preparation method thereof, relates to the fields of architectural paint and environmental protection, and is suitable for indoor decoration and air formaldehyde purification treatment. Background technique [0002] Water-based metallic coatings have been increasingly used in the field of interior decoration in recent years. Because of its metal-like texture flash effect, after being painted on the surface of buildings, it makes the decorations more dazzling and magnificent, so it is more and more favored by consumers. At present, the water-based metallic paints for interior walls on the market are mainly decorative, with the metal flash effect as the selling point, and relatively simple in terms of functionality. After use, it will basically not bring any change to the improvement of indoor air quality. So the coating that can improve the decora...
