preparation example Construction

[0037] A kind of preparation method of sound-absorbing coating that the present invention relates to, it mainly comprises the following steps:

[0038] a) Using a batching tank, under the state of stirring at a rotating speed of about 300 r / min, add an appropriate amount of water and dispersant in the raw materials of component A in order to reconcile;

[0039] b) Then increase the speed to 400-500 rpm, and slowly add the sepiolite in the raw material of component A according to the amount;

[0040] c) Continue to increase the speed to 1000-1500 rpm, and keep stirring for 30-40 minutes;

[0041] d) The rotation speed is reduced to 300-400 rpm, and the acrylic emulsion, film-forming aid, anti-fungal agent and thickener in the raw materials of component A are sequentially added, and finally the stirring is continued for 30-40 minutes; the sound-absorbing coating is obtained The required A component;

[0042] e) After being filled in cans, it is the finished product of componen...

Abstract

The invention relates to a sound-absorbing paint and a preparation method thereof. The sound-absorbing paint is formed by mixing and blending a component A and a component B according to a proper ratio, wherein the component A is prepared by mixing and blending raw materials including 0.1 to 0.5 weight percent of dispersant, 15 to 30 weight percent of sepiolite, 20 to 40 weight percent of acrylicemulsion, 0.5 to 1 weight percent of film-forming assistant, 0.5 to 1 weight percent of preservative and / or thickener and the balance of water, and the weight of all raw materials of the component A is 100 percent; the component B comprises polyphenyl foamed and ground particle raw material; and the weight mixing ratio of the component A to the component B is 1,000:(100-150). The finish has excellent sound-absorbing function and has the advantages of light weight, thermal insulation, elegance and the like. The finish can provide a more quiet and lovely indoor environment for people, so that the life quality can be improved effectively and the life of people can be prolonged.

Description

Technical field [0001] The invention is the field of building decorative materials, which involves a functional coating for the wall of the building in the building. Specifically, it is a sound absorption coatings and their preparation methods. Background technique [0002] With the development of the market economy, the price of the land has risen. Therefore, the land next to the land along the subway is up.Although residents living near the subway, although their transportation is convenient, it is inevitable that the noise interference caused by the long -term trapped in the subway will be long -term. [0003] In existing technologies, the indoor wall decoration mostly uses ordinary coatings or latex paint, etc. Although some have a certain waterproof effect, they do not have any sound absorption function. [0004] Many people mistakenly believe that the surface of the wall has a sound absorption function.In some early halls, the decoration of ordinary coatings is often used o...
