Abstract
A low-viscosity water pigment slurry of iron oxide yellow contains disperser, defoaming agent, anti-corrosion agent, cosolvent, iron oxide yellow and water. Its advantages are low viscosity, high stability and compatibility.
Description
Technical field
The present invention relates to a kind of aqueous color paste, especially a kind of iron oxide yellow aqueous color paste that is used for building coating (as emulsion paint).
Background technology
At present, a large amount of aqueous color pastes that use in the emulsion paint toning, wherein the iron oxide yellow mill base is with a kind of mill base of common, large usage quantity, and this class mill base is widely used in machinery equipment and plant produced.Because the shape of ferric oxide yellow pigment particle is aciculiform rather than sphere, cause the viscosity of iron oxide yellow pigments slurry to increase along with the increase of pigment content, when pigment content reached 60%, the viscosity of gained mill base had reached more than the 90KU, added pigment this moment again and had been difficult to disperse, be difficult to improve the content of pigment, and viscosity is too high, makes mill base be difficult for adjusting prescription and uses with other material matching, tinting strength, color developing and the consistency of mill base have also been influenced to a certain extent.So the pigment content of the iron oxide yellow mill base that general enterprise produces all is to be equal to or less than 60%.Though by selecting for use particle diameter iron oxide yellow pigments littler or non-aciculiform can suitably improve the mill base pigment content, cost is too high, and improve limited in one's ability, inadvisable substantially on producing.
Summary of the invention
In order to overcome the defective that the traditional colour slurry viscosity is too high, pigment content is low, the invention discloses a kind of low viscosity iron oxide yellow aqueous color paste, this mill base by dispersion agent, defoamer, sanitas, solubility promoter and water through scientific and reasonable collocation, can be in the viscosity that guarantees to reduce under the prerequisite that mill base various aspects of performance (as tinting strength, form and aspect, package stability etc.) remains unchanged mill base, to reach the purpose that improves the mill base pigment content.
The present invention is achieved like this:
This mill base is made up of 8～15% the dispersion agent of counting by weight percentage, 0.1～1% defoamer, 0.1～0.5% sanitas, 5～10% solubility promoter, 50～70% iron oxide yellow pigments and 10～30% water.
Wherein, the dispersion agent that is added among the present invention has two kinds, a kind of hydrophilic segmented copolymer, a kind of ion and non-ionic mixture of belonging to of belonging to.The defoamer that is added comprises two kinds altogether, and a kind of being mainly used in pressed down bubble, accounts for 30～50% (weight percents), and a kind of froth breaking that is mainly used in accounts for 50～70% (weight percents).
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 iron oxide yellow pigments, 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 low viscosity iron oxide yellow mill base 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 (60% pigment content) viscosity is lower, generally is lower than 75KU, both can directly use, and also can conveniently carry out the viscosity adjustment as required.
(2) consumption that only needs suitably to adjust dispersion agent can improve the pigment content of mill base easily, and be unlikely to take place viscosity too high, be difficult to the dispersive phenomenon, and gained mill base steady quality, good with the base paint consistency;
(3) compare with existing each iron oxide yellow mill base product, the mill base of gained of the present invention is convenient to the control except viscosity is low, and good with the consistency of each base paint, is difficult for taking place the loose colour grow diming phenomenon;
In sum, this mill base has reduced the viscosity of mill base preferably under the certain prerequisite of pigment content, and the mill base steady quality, and consistency is good, can be widely used in machinery equipment and plant produced, and production cost is lower, and very high practical value and economic worth are arranged.

Embodiment
Recently prepare this iron oxide yellow aqueous color paste by following weight percent:
10% dispersion agent;
0.5% defoamer (0.2% suds suppressor, 0.3% defoamer);
0.2 sanitas;
10% solubility promoter;
60% iron oxide yellow pigments;
19.3% water.
The iron oxide yellow aqueous color paste that makes by this prescription, its pigment content is 60%, viscosity is 75KU (that traditional is 90KU), fineness is less than 20 μ m, every index (as fineness, tinting strength etc.) does not change substantially after 50 ℃ of baking ovens are stored 2 months, be applicable to most emulsion paint systems, also can be used as industrial mill base and machine mill base and use.
This test-results shows: this mill base has reduced the viscosity of mill base preferably under the certain prerequisite of pigment content, and the mill base steady quality that become to be produced, and is of many uses, and higher utility is arranged.
