Abstract
The present invention discloses organic water-based orange paste with certain hydrophobicity. The orange paste is prepared from 10 to 20% of dispersing agent, 0.1 to 0.5% of defoaming agent, 0.1 to 0.5% of stiffening agent, 30 to 50% of organic orange pigment, 0.1 to 0.5% of disinfected preservative, 0.1 to 0.3% of pH regulating agent, 2 to 10% of water-holding antifreezing agent and 20 to 50% of water. Because the appropriate dispersing agent is added in the color paste, the color paste has certain hydrophobicity on the premise that the performance of the color paste in every aspect (such as coloring power, hue, storage stability and the like.) is ensured not to be changed, and the normal use of the color paste is not affected, so that the compatibility with exterior latex with hydrophobicity is enhanced. The defects of poor stability, poor coloring power, low compatibility with exterior latex with hydrophobicity, poor color matching property, and the like of traditional water-based color paste are overcome effectively.
Description
Technical field
The present invention relates to a kind of water-borne coatings, the organic orange slurry of especially a kind of hydrophobicity.
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 the orange pigments consumption is little, in the mill base system, still occupy critical positions.Because several years ago coating for internal and external wall all is based on hydrophilic coating, 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 organic orange slurry 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, hydrophilic organic orange slurry uses in this base paint, and phenomenon such as be easy to take place loose colour during toning, 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.How making mill base have excellent hydrophobic property, and have good state and stable tinting strength, is the insoluble technical barrier in mill base field.
Summary of the invention
The invention discloses a kind of organic orange slurry, added a kind of suitable dispersion agent in this mill base, can be under the prerequisite of the normal use that guarantees that mill base various aspects of performance (as tinting strength, 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 organic orange slurry stability, tinting strength is poor, with defectives such as hydrophobicity exterior wall latex paint consistency, toning property differences.
This mill base is made up of following component:
The dispersion agent of 10-20%;
The defoamer of 0.1-0.5%;
The thickening material of 0.1-0.5%;
The organic orange pigment of 30-50%;
The fungicidal preservative of 0.1-0.5%;
The pH regulator agent of 0.1-0.3%;
The water conservation antifreezing agent of 2-10%;
The water of 20-50% (if there is not specified otherwise, the percentage composition that occurs in this specification sheets all is weight percentage).
The dispersion agent that uses belongs to vinyl-based segmented copolymer in the mill base of the present invention, since this multipolymer on the hydrophilic molecules chain grafting some have hydrophobic group, make in this copolymer molecule chain and have hydrophilic radical and hydrophobic grouping simultaneously, can carry out effective the combination with the organic orange pigment of hydrophilic class like this, make mill base integral body have certain hydrophobicity again, improved compatibility performance and color development performance with various emulsion paints.Can also use propylene-based block copolymer, epoxy group(ing) segmented copolymer or other segmented copolymer that has hydrophobic grouping as dispersion agent in addition.
The consumption of dispersion agent is relevant with the used water hardness of mill base, and water hardness is big more, and the consumption of dispersion agent is also big more; In addition, the consumption of dispersion agent is relevant with the solid content of the molecular structure of used organic orange pigment and mill base, and the particle diameter of pigment also has a significant impact dispersant dosage, for example, the easier dispersion of micronization pigment ratio macrobead pigment, when therefore preparing mill base, the consumption of the former dispersion agent will be less than the latter.
Though use the excessive dispersion agent can more effective wetting and dispersed color, excessive free dispersant may make and take place crosslinkedly between each pigment particles, impels pigment particles that flocculation sediment takes place again, impairs the package stability of mill base on the contrary.Therefore, generally speaking, do not recommend to use excessive dispersion agent.
In the mill base preparation process,, therefore need to add proper quantity of defoaming agent and carry out froth breaking owing to reasons such as mechanical dispersion can cause producing in the mill base more bubble.It is the defoamer of main antifoam composition that mill base of the present invention can use with mineral oil or organosilicon, or by the defoamer of mineral oil and organic silicon compound.But because therefore defoaming effect and the froth breaking ability difference of different defoamers in different systems should be selected at concrete system.Can select the molecular level defoamer FoamStarA10 of Cognis company among the present invention for use.
Usually store fortnight at least after the mill base preparation, therefore it is rotten to prevent mill base to need to add fungicidal preservative, prolong the storage time of mill base, can use any commercially available fungicidal preservative among the present invention, for example 4,4-dimethyl oxazolidine and trimethylammonium homologue thereof also can use the fungicidal preservative of triazines fungicidal preservative or other type in addition.
In order to prevent sedimentary generation in the mill base, need in mill base, to add thickening material, the spendable thickening material of organic orange slurry of the present invention is of a great variety, as: xanthan gum, alginate, treated starch, Sudan Gum-arabic, carboxymethyl cellulose, guar gum, tragacanth gum, carob gum etc.Xanthan gum is first-selected material, because consumption is little, and effect is very obvious.
In some cases, it is acid that organic orange slurry is, and can cause corrosion when being applied to some material (as carbon steel), therefore, need to add the pH value that mill base is regulated in the pH regulator agent, can realize, also can use other commercially available pH regulator agent by adding a spot of AMP-95 (Angus company).
In order to prolong the time of drying of mill base, improve freeze-thaw resistance, need to add some water conservation antifreezing agent, generally can select propylene glycol or other water conservation antifreezing agent for use, ethylene glycol is eliminated at present gradually owing to have big toxicity and contaminative.
The production technique of the organic orange slurry of the present invention is basic identical with general mill base production technique, in suitable quantity of water, add an amount of dispersion agent, defoamer, fungicidal preservative, water conservation antifreezing agent during preparation in proportion, the slowly organic orange pigment of adding of back is uniformly dispersed, high speed dispersion pigment, sand milling then, reach satisfied fineness (being generally less than 20 μ m) after, add pH regulator agent and defoamer, froth breaking at a slow speed filters and gets final product.
