Technical field
The present invention relates to a kind of interior wall paint, be specifically related to a kind of multi-functional environment-protection interior wall paint.
Background technology
Development along with environmental consciousness, the interior wall paint environmental pollution has become with hazardness to human body the problem that can not be ignored, backward technology and product should be eliminated in interior wall paint production, the content of objectionable impurities be considered and to release time limit of hazard rating and the objectionable impurities of human body.For interior wall paint, mainly should develop low VOC environmental protection and do building coating, improve the quality parameter of coating.
Summary of the invention
The present invention provides a kind of multi-functional environment-protection interior wall paint in order to make up the deficiencies in the prior art.
Realize that technical scheme of the present invention is as follows:
The multi-functional environment-protection interior wall paint mainly is comprised of following compositions in weight percentage:
Titanium dioxide 18 ~ 23%
Kaolin 3 ~ 5%
Calcium carbonate (coarse whiting) 5 ~ 15%
Talcum powder 1 ~ 2%
Nanometer pure aluminium silicate 1 ~ 1.5%
ACRYLIC EMULSION 30 ~ 40%
Natvosol (HEC) 0.5 ~ 1%
Association type polyurethane thickener (HEUR) 0.2 ~ 0.5%
Covering type polymkeric substance 1 ~ 3%
Wilkinite 0.3 ~ 0.5%
Defoamer 0.05 ~ 0.2%
PH adjusting agent 1 ~ 2%
Wetting agent 1 ~ 2%
Siccative 4 ~ 6%
Multifunctional assistant 2 ~ 3%
Mould inhibitor 1.5 ~ 2.5%
Sterilant 0.1 ~ 0.2%
Dispersion agent 0.4 ~ 0.6%
Softening water 17 ~ 25%
The preparation method of multi-functional environment-protection interior wall paint, preparation were established is as follows:
(1) add softening water, dispersion agent, wetting agent, defoamer, pH value conditioning agent, mould inhibitor, the sterilant of formula ratio and process accurate-metering in container, the setting rotating speed is 300 ~ 400rpm, stir 3 ~ 5min, then regulating stirring velocity is 500 ~ 600rpm, is stirred to fully to mix.
(2) add pigment and the filler of formula ratio, the setting rotating speed is 600 ~ 800rpm, is stirred to mix.
(3) with grinding plant such as sand mills, be ground to fineness less than 40 ~ 50 μ m.
(4) under the whipped state of paint container 600 ~ 800rpm, add successively covering type polymkeric substance, nanometer pure aluminium silicate, ACRYLIC EMULSION, siccative, the thickening material of formula ratio, filter to get finished product after stirring.
The present invention has the following advantages and beneficial effect:
1, environmental-protecting performance of the present invention is excellent, and application property is good, and levelling property is good, has excellent scrub resistance, and paint film is level and smooth.
2, the present invention is applicable to the external coating of the differing materials such as indoor wall, top ceiling, brick structure, asbestos plate, and opacifying power is good, and spreading rate is high, strong adhesion, and effective mildew-resistant anticracking.
