[0029]

[0030] In the above embodiments, the auxiliary agents are 0.3-0.5% defoamer, 0.1-0.2% wetting agent, 0.25-1.0% thickener, 0.4-0.8% rheological agent, 0.4-0.6% anti-mold agent, pH adjustment 0.1% to 0.15% of dispersant, 0.5 to 1.0% of dispersant, 1.5 to 2% of humectant, 1.0 to 1.5% of film forming aid. The thickener is hydroxyethyl cellulose or organic bentonite thickener.

[0031] The water-based nano silver antibacterial agent used in the examples is a commercially available product.

[0032] The above examples were prepared according to the following preparation method:

[0033] (1) Pre-mixing: add half of the water needed to make the paint, water-based nano silver antibacterial agent, dispersant, wetting agent, 1 / 2 defoamer, anti-mold agent, thickener, and PH value regulator into the dispersion In the tank, stir for 15-25 minutes at a stirring speed of 300-500 rpm to form a jelly-like fluid.

[0034] (2) Dispersion: Add titanium dioxide and filler to the fluid prepared i...

Abstract

The invention belongs to the field of coatings, and in particular relates to an aqueous nano-antibacterial sound absorption coating and a preparation method thereof. The aqueous nano-antibacterial sound absorption coating comprises the following components in percentage by weight: 22-32% of an acrylic resin emulsion, 0.5-2% of an aqueous nano silver antibacterial agent, 5-12% of titanium dioxide, 15-22% of filler, 10-15% of expanded perlite, 3.065-7.75% of an additive and 18-30% of water. The invention further discloses the preparation method of the coating. The coating provided by the invention has special effects of being good in antibacterial property and capable of inhibiting mold and purifying organisms and smell in the air, and is excellent in sound absorption effect as the sound absorption coefficient is greater than 0.4. The coating is particularly applicable to coating of inner walls, ceilings and the like of buildings such as music halls, movie theaters, grand halls, hospital wards and bioclean rooms.

Description

Technical field [0001] The invention belongs to the field of coatings, and specifically relates to a water-based nano antibacterial sound-absorbing coating, as well as a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the rapid improvement of people's living standards, the environmental awareness of the whole society has also increased. Environmentally friendly new technologies and new materials have received more and more attention. In many fields, healthier and more environmentally friendly materials are eliminating outdated technologies with high pollution and high energy consumption. The society's attention to noise pollution is an obvious example. It is considered to be the third largest public hazard after air pollution and water pollution. Many companies have grasped the trend and quickly invested in the application research of noise control. Sound-absorbing coatings came into being. Most of the existing so...
