Embodiment 1

[0031] A special sound-absorbing water-based paint for conference halls according to the present invention, said special-purpose sound-absorbed water-based paint for conference halls comprises the following components by mass percentage:

[0032]

[0033]

[0034] Described wetting agent A is the alkyl polyoxyethylene ether of non-ionic low foaming effect, as the BD-109 of Dow, the LCN070 of Clariant etc.; Described defoamer is mineral oil defoamer, such as Blackburn's CF-246, Corning's NXZ, F-111.

[0035] The thickener A is hydroxyethyl cellulose, which prevents the sedimentation of heavy pigments and fillers, and introduces yield value and thixotropy for the coating system, such as 250HBR of Ashland Company; the thickener B is ordinary Hydrophobically modified acrylic alkali swelling, such as Dow TT615, Elements 150 etc.

[0036] The leveling agent is matched with non-ionic polyurethane thickening leveling agent, such as RM2020 or RM2050D of Dow Company. The three...

Embodiment 2

[0050] The difference between embodiment 2 and embodiment 1 is: a special sound-absorbing paint for conference halls of the present invention, said special sound-absorbing paint for conference halls comprises the following components by mass percentage:

[0051]

[0052]

[0053] The bactericidal antifungal agent is 2-n-octyl-4-isothiazolin-3-ketone benzimidazole, isothiazole derivatives, hydroxymethyl urea 1,6 dihydroxy-2-5 dioxygen from Pvrogiven company A combination of three in heterocyclohexane.

[0054] Described antifreezing agent is propylene glycol.

[0055] The preparation method of special sound-absorbing paint for conference halls according to the present invention is characterized in that it comprises the following steps:

[0056] In step (1), preparation of pre-coagulated slurry: Accurately weigh each component according to the stated ratio, put deionized water in the dispersion tank, start stirring, slowly add thickener A while stirring at low speed, and ...

Embodiment 3

[0062] The difference between embodiment 3 and embodiment 1 is: a special sound-absorbing paint for conference halls of the present invention, said special sound-absorbing paint for conference halls comprises the following components by mass percentage:

[0063]

[0064]

[0065] The fungicide and antifungal agent is a combination of two kinds of isothiazole derivatives and hydroxymethylurea 1,6 dihydroxy-2-5 dioxane.

[0066] The preparation method of special sound-absorbing paint for conference hall of the present invention comprises the following steps:

[0067] In step (1), preparation of pre-coagulated slurry: Accurately weigh each component according to the stated ratio, put deionized water in the dispersion tank, start stirring, slowly add thickener A while stirring at low speed, and then disperse at high speed The time is 20min; the low-speed stirring rate is 500r / min, and the high-speed dispersion rate is 1500r / min;

[0068] In step (2), pre-mixing: reduce the ...

Abstract

The invention discloses a special sound absorption water paint for a conference hall and a preparation method of the special sound absorption water paint. The special sound absorption water paint forthe conference hall comprises the following components in percentage by mass: deionized water, attapulgite, a thickening agent A, a wetting agent, a dispersing agent, an antifreezing agent, a defoaming agent, a film forming auxiliary, a pH value stabilizer, titanium dioxide, sound absorption particles A, sound absorption particles B, sound absorption particles C, washed kaoline, talcum powder, a modified polymer emulsion, waterborne polyamide wax, a waterborne silicon emulsion, a hydrophobing agent, a thickening agent B, a leveling agent, a bacterial and antimildew agent and deionized water. When being used in the conference hall, the water paint disclosed by the invention has an obvious silencing effect for the outside of the conference hall and has a good paint surface leveling effect. The water paint disclosed by the invention can be constructed on a wall by using various roller tools or sprayers, so that noise outside the conference hall is reduced, and meanwhile, a good wall beautifying level is achieved. In addition, the special sound absorption water paint is integrated with an environmental protection concept and has the characteristics of antimildew property, dampproofness, pollution resistance and dust prevention.

Description

technical field [0001] The invention relates to a functional water-based paint for building interior walls, in particular to a special sound-absorbing water-based paint for conference halls and a preparation method thereof. Background technique [0002] With the development of the times, all large, medium and small enterprises are equipped with their own conference halls. However, due to space constraints in many enterprises, the distance between the conference hall and the office area is very small. The trouble caused by this is that the noise in the conference hall can easily affect the normal work of the office area outside the conference hall. Usually the conference hall will arrange some sound-absorbing materials such as: cavity structure, sound-absorbing panels, sound-absorbing cotton, etc. These measures not only take up a lot of space, but also have a high cost and greatly affect the aesthetics of the conference hall. Therefore, a wall paint that can have a good so...
