Embodiment 1

[0028] A kind of orthographic projection curtain wall water paint, comprises the following components by mass percentage:

[0029]

[0030] The wetting agent A is a non-ionic low-foaming alkyl polyoxyethylene ether, such as Dow's BD-109, Clariant's LA070, etc.; the wetting agent B is EO / PO- Block copolymers, which provide compatibility and stability between organic pigments, carbon black, etc. The special three-component copolymerization dispersant, such as Corning's H34, etc., can improve the HLB value of the entire coating system, so that the performance of the entire paint film far exceeds that of ordinary latex paints on the market.

[0031] The defoamer is a mineral oil defoamer, such as Blackburn's CF-246, Corning's NXZ, F-111, etc. The pigments and fillers are effectively dispersed and form a stable, bubble-free, and shrinkage-free coating system.

[0032] The thickener A is hydroxyethyl cellulose, which prevents the sedimentation of heavy pigments and fillers, and ...

Embodiment 2

[0044] A kind of orthographic projection curtain wall water paint, comprises the following components by mass percentage:

[0045]

[0046] The difference from Example 1 is that the bactericidal antifungal agent of the present embodiment is 2-n-octyl-4-isothiazolin-3-ketone benzimidazole, isothiazole derivatives, hydroxymethylurea 1 of Pvrogiven company , The combination of the three in 6 dihydroxy-2-5 dioxane, the ratio is: 1:1:1. And described antifreezing agent is propylene glycol.

[0047] The preparation method of front projection curtain wall water paint of the present invention comprises the steps:

[0048] 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 the high-speed dispersion time is 18min; the low-speed stirring rate is 480r / min, and the high-speed dispersion rate is 1800r / min; ...

Embodiment 3

[0054] A kind of orthographic projection curtain wall water paint, comprises the following components by mass percentage:

[0055]

[0056] The difference from Example 1 is that the bactericidal antifungal agent described in this example is a combination of two types of isothiazole derivatives and hydroxymethylurea 1,6 dihydroxy-2-5 dioxane, and the ratio 1:1.

[0057] The preparation method of front projection curtain wall water paint of the present invention comprises the steps:

[0058] 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 the high-speed dispersion time is 20min; the low-speed stirring rate is 500r / min, and the high-speed dispersion rate is 1500r / min;

[0059] Step (2), pre-mixing: reduce the dispersion speed, add wetting agent A, wetting agent B, dispersant, defoamer, film-for...

Abstract

The invention discloses orthographic projection curtain wall water paint which comprises the following components: deionized water, a thickening agent A, a wetting agent A, a wetting agent B, a dispersant, a defoaming agent, filming aids, a pH value stabilizer, an anti-freezing agent, titanium dioxide, barite, a pearl pigment, a modified polymer emulsion, a thickening agent B, a leveling agent, asterilization anti-mold agent, gain micro beads and deionized water. The invention further discloses a preparation method of the orthographic projection curtain wall water paint. The water paint disclosed by the invention is capable of replacing common external curtain cloth and has the advantages of being wide in view angle, high in gain, high in water resistance, excellent in anti-mold function,and the like, and in addition, the trouble of mounting and moving curtain cloth can be avoided.

Description

technical field [0001] The invention relates to a paint for interior walls of buildings, in particular to a water paint for front projection curtain walls and a preparation method thereof. Background technique [0002] With the improvement of people's material level, people's spiritual pursuit is getting higher and higher. Home projectors have appeared in every household, but installing a projector screen at home really affects the appearance. Therefore, a coating that can achieve the effect of the projector screen to replace the projector screen has a good market space. This kind of coating can achieve the screen projection effect of ordinary households without occupying the space of bedrooms and living rooms. Adding decorative frames and putting searchlights on the curtain wall has a good visual effect. Contents of the invention [0003] The purpose of the present invention is to address the above problems, providing a front projection curtain wall water paint with wide...
