Description
Technical field
It is applied to various coating for internal and external wall the present invention relates to a kind of preparation method of building coating priming paint, more particularly to one kind
Imidizate SMA modified cation phenylpropyl alcohol seal coats.
Background technology
The base material of skin is generally cement mortar or concrete surface, and its feature is concrete dynamic modulus, alkalescence is strong.It is wherein many
Pore structure makes its water imbibition strong, causes decorative coveringn surface not smooth enough, easily causes film to wrinkle, and film may be caused to do
It is dry too fast and cause finish paint to ftracture；Alkalescence can cause by force the chemical degradation of resin in coating, accelerate ginkgo seeds process, reduce and apply
The service life of layer, while causing granules of pigments exposed, losing the protection of resin causes colour fading；This feature based on base material,
It is required that it must use alkali-resistant primer, alkali, the precipitation of salinity are effectively prevented, and a firm attachment base is provided for finish paint
Bottom, could keep the beautiful lasting of decorative coveringn.
Existing phenylpropyl alcohol seal coat, sealing acrylic priming paint are typically all that the modulation of anionic emulsion is formed, but are existed
Poor adhesive force, the weak shortcoming of alkali resistance；The particle diameter of emulsion is larger, and surface tension is also very big, and general is difficult to penetrate into inside ground
Tiny pore in, so the density of surface of bottom material film can only be relied on to realize the effect of back cover.
Due to the particularity of latex paint film forming, chemical reaction of becoming film can not occur between macromolecule, simply according to itself
Moisture evaporation, macromolecule micelle softens in the presence of coalescents and then mutually extrudes film forming, so paint film is not close, space
Larger more, the water vapour formed after film forming in the porous coating of similar application on human skin, base material can be appeared slowly；When it is used for
During the cement wall not parched completely, in the slow drying process of wall, alkali point and soluble-salt in cement can be with aqueous solution shapes
Formula is oozed out from cement capillary through coating, runs into the carbonate that the CO2 in air generates indissoluble, and this whiteness is extremely difficult
Remove completely, it can not only cause the problems such as coating discoloration is grown dim, peeled off, and partial white thing can also be downward by rain drop erosion
Sagging formation tear stains, have a strong impact on the decoration and protective value of film；The effect of alkali-resistant primer is exactly salt, alkali in closed substrate
Property material migrate upwards, to reduce the erosion to finish paint, increase the adhesive force of finish paint, and can also prevent finish paint from excessively penetrating into
Inside base material, the consumption of finish paint is reduced, therefore in exterior wall coating application, alkali-resistant sealing primer is essential supporting painting
Material.
The content of the invention
The present invention is to select imidizate SMA modified cation styrene-acrylic emulsions, with traditional anionic emulsion seal coat
Compare, the seal coat has following characteristics：Alkali burnout resistance, salting-out resistance, closure are strong；Superior ground permeability, the bottom of with
Material, finish paint adhesive force are good；Excellent temperature tolerance, water resistance；Cationic characteristic：It is crosslinked in the basic conditions, alkali resistance, resistance to salting-out
Performance is fabulous；It is solvent-free, without alkyl phenol, without heavy metal, extremely low VOC, environmental protection.
In order to solve the problems, such as techniques as described above, the present invention takes following technical scheme：It is sub- the present invention relates to a kind of acyl
Amination SMA modified cation phenylpropyl alcohol seal coats, its basic recipe is：Imidizate SMA modified cations styrene-acrylic emulsion 30%
~50%, titanium dioxide 4%~8%, extender pigment 10%~25%, propane diols 1%~5%, auxiliary agent 2%~10%, deionization
Water 20%~35%.
Wherein, described extender pigment fineness is 800~1500 mesh, from powdered whiting, kaolin, talcum powder, silicon
The combination of calcium powder, at least more than three kinds of sericite powder.
Described auxiliary agent at least includes dispersant, coalescents, thickener, wetting agent, defoamer, pH adjusting agent and anti-corrosion
The combination that at least more than three kinds of bactericide.
The present invention proposes a kind of preparation method preparation technology of imidizate SMA modified cations phenylpropyl alcohol seal coat such as
Under：A water, defoamer, dispersant, wetting agent and bactericide are added in agitator tank based on formulation weight ratio, after low speed is uniformly dispersed
Titanium dioxide and extender pigment are added, 15min~30min is then disperseed at a high speed, after the fineness of slurry is qualified, is added under middling speed state
Enter imidizate SMA modified cation styrene-acrylic emulsions, then at the uniform velocity add coalescents, the good viscosity of stirring and adjusting and pH value, i.e.,
A kind of imidizate SMA modified cations phenylpropyl alcohol seal coat is made.
The imidizate SMA modified cation phenylpropyl alcohol seal coats that the present invention is made, with excellent alkali burnout resistance, salt resistance
Analysis property, closure is strong；Superior ground permeability is good with ground, finish paint adhesive force；Excellent temperature tolerance, water resistance；Cation
Characteristic, is crosslinked in the basic conditions, and alkali resistance, salting-out resistance can be fabulous；It is solvent-free, without alkyl phenol, without heavy metal, it is extremely low
VOC, environmental protection；Suitable for the application on the surfaces such as inner-outer wall, cement wall, concrete, plasterboard, asbestos board.
