Abstract
The invention relates to a preparation method for a cationic silicone/acrylic emulsion alkali resistant seal primer. The basic formula of the seal primer is as follows: 30% to 50% of emulsion, 4% to 8% of titanium dioxide, 5% to 12% of ground limestone, 5% to 10% of kaolin, 1% to 3% of talcum powder, 2% to 6% of coalescing agent, 1% to 5% of propylene glycol, 0.5% to 3% of thickening rheological agent, 2% to 5% of assistant and 20% to 35% of deionized water. The seal primer has the advantages of strong permeability, excellent weather and water resistance, good adhesion with substrate and paint, good self cleanness and environmental friendliness, excellent sealing performance, excellent alkali resistance and higher alkali and salting-out resisting performance. Therefore, the seal primer is suitable for being coated on the surfaces of external walls, internal walls, cement walls, concrete, gypsum boards, asbestos plates and the like.
Description
Technical field
The present invention relates to a kind of preparation method of trade sales coating priming paint, relate in particular to a kind of positively charged ion organosilicon crylic acid latex alkali resistant seal coat that is applicable to various coating for internal and external wall.
Background technology
Mostly the base material of skin is sand-cement slurry or concrete surface, and its characteristics are that porous crack, alkalescence are strong.Wherein vesicular structure makes its water-absorbent strong, causes the decorative coveringn surface smooth inadequately, causes easily to film wrinklingly, and possibly cause dried coating film too fast and cause finish paint cracking; Alkalescence can cause the chemical degradation of resin in the coating by force, quickens to film ager process, reduces the working life of coating, causes granules of pigments exposed simultaneously, and the protection that loses resin causes fading.Based on this characteristics of base material, require it must use alkali resistant priming paint, stop separating out of alkali, salinity effectively, and, could keep the beautiful lasting of decorative coveringn at the bottom of finish paint provides a firm adherance.
Existing phenylpropyl alcohol seal coat, sealing acrylic priming paint generally all are that the modulation of anionic emulsion forms, but have poor adhesive force, the shortcoming that alkali resistance is weak; Particle size of emulsion is bigger, and surface tension is also very big, generally is difficult to be penetrated in the inner tiny pore of ground, so can only rely on the effect that density that substrate surface films realizes back cover.
Because the film forming singularity of latex coating; Between the polymer chemical reaction film forming can not take place, just according to self moisture evaporation, the polymer micelle is softening and then mutual extrusion film forming under the effect of film coalescence aid; So paint film is not tight; The space is more more, forms the porous coating of similar human skin after the film forming, and the water vapor in the base material can slowly appear.When it was used for some cement walls that do not parch fully, in the slow drying process of body of wall, the alkali in the cement divided and soluble salt can ooze out through coating from the cement kapillary with aqueous solution form, runs into airborne C0
2Generate the carbonate of indissoluble, this white mass extremely difficulty is removed fully, problem that it not only can cause that the coating variable color is grown dim, peeled off etc., and also the white thing of part can also form tear stains by the downward sagging of rain drop erosion, have a strong impact on the decoration and the protective value of filming.The effect of alkali resistant priming paint is exactly salt, the upwards migration of alkaline matter of sealing in the base material, to reduce the erosion to finish paint, increases the sticking power of finish paint, and can stop finish paint too much to be penetrated into base material inside, reduces the consumption of finish paint.In the exterior wall coating application, the alkali resistant seal coat matched coating that is absolutely necessary.
Summary of the invention
The present invention selects self-crosslinking positively charged ion organosilicon crylic acid latex for use, at room temperature need not add other auxiliary agent and just can take place crosslinked.Compare with traditional solvent bottom paint or anionic emulsion seal coat; This seal coat has following characteristic:
self-crosslinking, closure strong: after the moisture evaporation in the polymkeric substance; Promptly begin self-crosslinking reaction; Heat, alkaline matter all can promote crosslinking reaction; Can improve polymerization crosslinking density, improve closure.
good sticking power: superior ground perviousness, adhere to well with ground, finish paint.Stability to aging, water-repellancy that
is excellent: in drying process, crosslinked paint film has fabulous water-repellancy and stability to aging.
cationic characteristic: crosslinked under alkaline condition, alkali-resistivity, the anti-performance of saltouing are fabulous.
feature of environmental protection: solvent-free, self-cleaning function.
So the seal coat perviousness that the present invention processes is strong, good weathering resistance, water tolerance and sticking power, and excellent closure and alkali-resistivity have higher alkali resistant, the anti-performance of saltouing.
In order to solve technical problem recited above; The present invention takes following technical scheme: the present invention relates to a kind of positively charged ion organosilicon crylic acid latex alkali resistant seal coat, its basic recipe is: emulsion 30%～50%, white titanium pigment 4%～8%, water-ground limestone 5%～12%, kaolin 5%～10%, talcum powder 1%～3%, film coalescence aid 2%～6%, Ucar 35 1%～5%, thickener rheology agent 0.5%～3%, auxiliary agent 2%～5%, deionized water 20%～35%.
Wherein, emulsion is selected self-crosslinking positively charged ion organosilicon crylic acid latex for use.
White titanium pigment is selected one or more combination of rutile titanium white powder or anatase thpe white powder for use.
Water-ground limestone is selected 1000 purpose powders for use.
Kaolin is selected 1000 purpose powders for use.
Talcum powder is selected 1000 purpose powders for use.
Film coalescence aid is selected one or more combination of glycol ether, propylene glycol and alcohol ester-12 for use.
Auxiliary agent comprises one or more combination of dispersion agent, wetting agent, skimmer, PH regulator and anticorrosion and bactericidal agent at least.
Thickener rheology agent is one or more combination of association type propenoate, hydrophobic association type polyurethane and Natvosol.
It is following that the present invention proposes a kind of preparation method preparation technology that all can the alkali resistant seal coat: be added to water, skimmer, dispersion agent, wetting agent and sterilant in the stirred pot by the formulation weight ratio; After being uniformly dispersed, low speed adds powder white titanium pigment, lime carbonate, high mountain range scholar and talcum powder; High speed dispersion 15min～30min then; After treating that the fineness of slurry is qualified, the middling speed state adds organosilicon crylic acid latex down, at the uniform velocity adds film coalescence aid then; Good viscosity of stirring and adjusting and pH value promptly make a kind of positively charged ion organosilicon crylic acid latex alkali resistant seal coat.
The seal coat perviousness that the present invention processes is strong, good weathering resistance, water tolerance and sticking power, and excellent closure and alkali-resistivity have higher alkali resistant, the anti-performance of saltouing.Be applicable to the application on surfaces such as interior exterior wall, cement wall, concrete, plasterboard, asbestos plate.
