Abstract
The present invention discloses a titanium white water-based color paste with a certain hydrophobic property, which is prepared from 6 to 12 wt% of dispersing agent 1, 1 to 3 wt% of dispersing agent 2, 0.1 to 0.5 wt% of defoaming agent 1, 0.1 to 0.6 wt% of defoaming agent 2, 6 to 12 wt% of cosolvent, 0.2 to 0.6 wt% of stiffening agent, 50 to 70 wt% of titanium white pigment, 0.1 to 0.5 wt% of preservative, 0.1 to 0.3 wt% f pH regulating agents and 10 to 30 wt% of water. Appropriate dispersing agents and defoaming agents are added to the color paste, and the color paste has certain hydrophobic property on the premise that the performances (such as coloring power, hue, storage stability, etc.) of the color paste are not changed, and the normal use of the color paste is not affected. Thereby, the compatibility of the color paste and exterior wall latex with hydrophobic property is enhanced. The defects of poor stability, poor coloring power, low compatibility with exterior wall latex with hydrophobic property, low color match property, etc. of the traditional water-based color paste are overcome.
Description
Technical field
The present invention relates to a kind of aqueous color paste, especially a kind of titanium white aqueous color paste that is used for the toning of hydrophobicity external wall of building emulsion paint.
Background technology
Begun to use in a large number aqueous color paste in the emulsion paint toning at present, used pigment comprises mineral dye such as red iron oxide, iron oxide yellow, and various pigment dyestuff such as phthalocyanine blue, organic red, organic yellow etc.Though it is the white colorant consumption is little, often indispensable when transferring tinted paint.Though white pigment has number of different types, because the rutile type titanium white pigments has splendid acid and alkali-resistance, weather-proof, solvent resistance, and excellent covering performance, so the stock white in the aqueous color paste is generally all selected the rutile type titanium white pigments for use.Because exterior wall all is based on hydrophilic coating several years ago, and the easier realization in water-based system of wetting ability mill base good open jar state and package stability, the research difficulty is also relatively low, and therefore, nearly all in the market titanium white mill base all is to belong to the wetting ability mill base.
Along with exterior wall latex paint in recent years develops to hydrophobic direction gradually, the base paint hydrophobicity is more and more stronger, and wetting ability titanium white mill base uses in such base paint, and toning problem such as be easy to take place loose colour, grow dim has a strong impact on the use properties of hydrophobicity colored paint.Improve the consistency of mill base and hydrophobic latex lacquer, improving the color paste toning performance is mill base field urgent problem, but because lyophobic dust often is difficult to keep stability for a long time in water-based system, therefore the hydrophobicity mill base is easy to degradation problem under water, precipitation, the tinting strength occur dividing, and influence is used.Titanium dioxide pigment is because than great, it is more outstanding that these problems seem in addition.How making mill base have excellent hydrophobic property, and have good state and stable tinting strength, is that the mill base field is difficult to a technical solution difficult problem.
Summary of the invention
The invention discloses a kind of certain hydrophobic titanium white aqueous color paste that has, added the combination of suitable dispersion agent and defoamer in this mill base, can be under the prerequisite of the normal use that guarantees that mill base various aspects of performance (as opacifying power, form and aspect, package stability etc.) is constant, do not influence mill base, make mill base have certain hydrophobicity, thus the consistency of raising and hydrophobicity exterior wall latex paint.It has overcome traditional water-based stability of pigment paste, tinting strength is poor, with defectives such as hydrophobicity exterior wall latex paint consistency, toning property differences.
A kind of hydrophobicity titanium white aqueous color paste, it is composed as follows by weight percentage:
8% dispersion agent Hydropalat 257;
2% dispersion agent, macromolecule polyacrylic acid salt;
0.5% defoamer Foamaster NXZ;
0.3% defoamer Foamaster lll;
10% solubility promoter, propylene glycol or ethylene glycol;
60% titanium dioxide pigment;
0.2% sanitas;
0.2% PH conditioning agent;
18.8% water.
The dispersion agent that is added among the present invention comprises two kinds altogether, a kind ofly belongs to hydrophilic segmented copolymer, a kind ofly belongs to hydrophilic macromolecule polyacrylic acid salt.The defoamer that is added comprises two kinds altogether, and a kind of being mainly used in pressed down bubble, as polyether-modified polysiloxane; A kind of froth breaking that is mainly used in is as mineral oils.
Employed solubility promoter can be organic solvents such as propylene glycol, ethylene glycol among the present invention, and sanitas can be materials such as isothiazolinone, and the pH regulator agent is a strong alkaline substance, as ammoniacal liquor etc.
When preparing this mill base, add an amount of dispersion agent, defoamer, sanitas, solubility promoter in water, the back that is uniformly dispersed slowly adds titanium dioxide pigment, then high speed dispersion half an hour, sand milling is 2 hours again, adds pH regulator agent and defoamer then, froth breaking at a slow speed filters and gets final product.
The production technique of titanium white aqueous color paste of the present invention is basic identical with the production technique of general iron oxide yellow mill base, and need not increases extra equipment or operation, need not to carry out special processing, is convenient to utilize existing installation to realize producing.
Compare with traditional product, the mill base that adopts the present invention to produce has following advantage:
(1) mill base of gained of the present invention has certain hydrophobicity, has good consistency and splendid toning with the hydrophobicity exterior wall latex paint;
(2) though the titanium white mill base of gained of the present invention is to aim at the design of hydrophobicity exterior wall latex paint, be equally applicable to the toning of exterior wall latex paint in other wetting ability;
(3) the hydrophobicity titanium white mill base of gained of the present invention has the good jar state of opening, and has good storage stability simultaneously, and it is above and phenomenons such as branch water, precipitation can not occur to store half a year;
(4) mill base of gained of the present invention has optimum size distribution, has guaranteed the good distribution of pigment and the splendid opacifying power of mill base;
(5) mill base of gained of the present invention is difficult for returning slightly, thereby has fabulous package stability, and mill base is after placing some months, and fineness, opacifying power, consistency and form and aspect almost do not change;
In sum, the aqueous color paste of gained of the present invention has certain hydrophobicity, and tinting strength is good, and stability in storage is good, with the hydrophobicity exterior wall latex paint good consistency and toning property is arranged.Overcome traditional water-based stability of pigment paste, tinting strength is poor, with defectives such as hydrophobicity exterior wall latex paint consistency, toning property differences.Be mainly used in the toning that the aqueous architectural emulsion paint gets, be particularly useful for the hydrophobicity exterior wall latex paint.
