Tradition is all the coating for organic solvent, the contaminative of this coating is serious, therefore, now everybody big area bring into use water-borne coatings, and for exterior coating, need the wherein important technological problems solved to be mildew-resistant, but its fungicidal properties of existing water-borne coatings is all not good enough, and in preparation process complex process.
Summary of the invention
The object of this invention is to provide that a kind of fungicidal properties is good, the preparation method of the simple water mildow-proof finish paint of good springiness, technique.
For achieving the above object, the preparation method of water mildow-proof finish paint comprises the steps, according to weight percent meter,
(1) take the mixture of protection type mildew-resistant capsule sporozoite that 22%-28% weight ratio is 3:1 and rubber powder, 20%-25% deionized water, 8%-12% filler and 5%-7% auxiliary agent to stir under the rotating speed of the temperature 400 ~ 800r/min of 70-80 DEG C;
(2) take 30%-40% aqueous polyurethane emulsion to join in step (1), and react 20-40min while stirring in the water-bath of 80-100 DEG C;
(3) take 0.2%-0.5% defoamer, 0.1%-0.5% sanitas, 0.5%-0.9% thickening material join in step (2), under 400 ~ 800r/min speed conditions, stir 5 ~ 10 minutes; Obtain water mildow-proof finish paint after filtration.
Further, the weight percent of each raw material is:
Aqueous polyurethane emulsion 35%
Weight ratio is the protection type mildew-resistant capsule sporozoite of 3:1 and the mixture 25% of rubber powder
Deionized water 22.6%

Sanitas 0.3%
Thickening material 0.7%.
Further, filler is the one in talcum powder, dicalcium powder, kaolin, process white.
Further, described auxiliary agent is film coalescence aid, and described film coalescence aid is alcohol ether solvent or the cruel kind solvent of alcohol.
Further, described defoamer is polysiloxane-polyether copolymer, and described sanitas is nitrite, and described thickening material is one or both in association type polyurethane thickener.
The invention has the beneficial effects as follows: the release actives of the protection type mildew-resistant capsule sporozoite energy continuous and effective in the present invention, the effect of itself and rubber powder and aqueous polyurethane emulsion, reaches permanently effective mildew-proof function, can also improve the elasticity of paint film; Meanwhile, coating of the present invention can form that sticking power is 0 grade, hardness is greater than 1H, the coating that water tolerance is greater than 250 hours on substrate surface.Meanwhile, technique is simple, and cost is low.
