Detailed Description

The invention will be further understood by reference to the following detailed description of preferred embodiments of the invention and the examples included therein. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. To the extent that a definition of a particular term disclosed in the prior art is inconsistent with any definitions provided herein, the definition of the term provided herein controls.

As used herein, a feature that does not define a singular or plural form is also intended to include a plural form of the feature unless the context clearly indicates otherwise. It will be further understood that the term "prepared from …," as used herein, is synonymous with "comprising," including, "comprising," "having," "including," and/or "containing," when used in this specification means that the recited composition, step, method, article, or device is present, but does not preclude the presence or addition of one or more other compositions, steps, methods, articles, or devices. Furthermore, the use of "preferred," "preferably," "more preferred," etc., when describing embodiments of the present application, is meant to refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. In addition, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention.

The term "pure acrylic emulsion" refers to a dispersion of a high molecular compound obtained by polymerizing an acrylic acid (ester) monomer in water, is safe and environment-friendly, and can be used as a raw material for preparing high-grade latex paint, but the emulsion has a high film-forming temperature, is poor in applicability in cold plateau areas, has a significantly reduced film-forming speed, is easy to sag, has a significantly higher ultraviolet intensity than that in plain areas, and further improves the ultraviolet resistance of latex paint products.

From the viewpoint of controlling cost and raw material stability, in some preferred embodiments, the pure acrylic emulsion has a solid content of 40-60 wt%, and the higher the solid content of the pure acrylic emulsion, the lower the production cost of the latex paint, but the too high solid content makes the raw material emulsion prone to delamination during storage.

The acrylic emulsion in the present application is not particularly limited and may be commercially available, for example, ENCOR series products manufactured by abcoma, france.

The term "filler" is used herein to provide hiding power to the latex paint and also to reduce production costs, and in some embodiments, the filler is selected from a mixture of one or more of kaolin, attapulgite, montmorillonite, calcium carbonate, titanium dioxide, alumina, zinc oxide.

In order to improve the mechanical property and the covering power of the latex paint at the same time, in some preferred embodiments, the filler is a mixture of kaolin, calcium carbonate and titanium dioxide, and the weight ratio of the kaolin to the calcium carbonate to the titanium dioxide is 1: (3-4): (1-2).

In some preferred embodiments, the kaolin is calcined kaolin having a mesh size of 1000 to 1500 mesh. The term "calcined kaolin" as used herein refers to kaolin that is to be sintered in a calciner.

In some preferred embodiments, the calcium carbonate is ground calcium carbonate with a mesh size of 600 to 1000 mesh. The term "ground calcium carbonate" herein refers to calcium carbonate powder ground from natural carbonate minerals such as calcite, marble, limestone.

In some preferred embodiments, the titanium dioxide is rutile titanium dioxide, and the mesh number is 400-600 meshes. The term "rutile titanium dioxide powder" as used herein means a titanium dioxide powder having a crystal form of rutile.

The inventor finds in a careful study that when the composite filler is used for filling the latex paint, the latex paint has strong covering power and high whiteness, and meanwhile, various resistances in plateau areas are also obviously improved, because calcined kaolin has a loose structure, the void ratio in the system is increased, the light scattering coefficient is increased, the surface area is increased, the phenomena of refraction, reflection and the like on an interface are increased, the opacity and the whiteness are increased, but the mechanical property, the wear resistance and the like of the paint film cannot be improved due to the loose structure; the heavy calcium carbonate has irregular particle shape and wider particle size distribution due to the production process, the running path of light in a paint film structure is increased, the energy of the light in continuous refraction and reflection is gradually reduced, the destructiveness on a polymer structure is reduced, the calcium carbonate just makes up the deficiency of kaolin in the reinforcing aspect, and the performance of the paint film for bearing external force is improved; the titanium dioxide can improve the covering power of the emulsion paint, absorb ultraviolet rays, change the adaptability of the emulsion paint in plateau areas, and ensure that electron hole pairs generated after the rutile type titanium dioxide absorbs the ultraviolet rays are easy to recombine, thereby avoiding the fracture of chemical bond in the system caused by free radicals.

The inventor unexpectedly discovers that when kaolin, calcium carbonate and titanium dioxide with different meshes are added into the emulsion paint according to a certain proportion, the abrasion resistance, the ageing resistance and the high and low temperature resistance of the emulsion paint are obviously improved, and the reason is that the wider particle size distribution of the heavy calcium carbonate is matched with the kaolin with higher meshes and the titanium dioxide with lower meshes, the gaps in the structure are occupied by filler particles as much as possible, the abrasion resistance is improved, the moving space of a high molecular chain segment is reduced, the mobility of the polymer structure is weakened in the frequent change of high and low temperatures in a plateau area, the stability is improved, in addition, the compact filler system shields most ultraviolet rays, and the ageing resistance of a paint film is improved.

The fillers in the application can be obtained commercially, and the required mesh number can be customized by a purchasing manufacturer.

In some preferred embodiments, the thickener is a mixture of polyacrylic thickener, polyurethane thickener, and cellulosic thickener, and the weight ratio is 1: (0.5-1.5): (0.5 to 1.5).

The polyacrylic thickener in this application may be commercially available, such as ACRYSOL ASE-95NP, ACRYSOL ASE-60, ACRYSOL DR-5500, ACRYSOL TT-935, and the like, preferably ACRYSOL TT-935, manufactured by Rohm and Haas.

The polyurethane-based thickener in the present application may be commercially available, for example, ACRYSOL RM-2020NPR, ACRYSOL RM-3030NPR, ACRYSOL RM-995, ACRYSOL RM-8W, ACRYSOL RM-845, etc., preferably ACRYSOL RM-2020NPR, produced by Rohm and Haas.

In some preferred embodiments, the cellulosic thickener is selected from the group consisting of a mixture of one or more of hydroxypropyl methylcellulose, carboxymethyl cellulose, ethyl cellulose, methyl cellulose, hydroxyethyl cellulose, cellulose acetate butyrate; more preferably, the cellulose-based thickener is hydroxyethyl cellulose (HEC).

In some preferred embodiments, the hydroxyethyl cellulose has a viscosity of 30000 to 100000 mPa-s; more preferably, the hydroxyethyl cellulose has a viscosity of 52000mPa · s.

The viscosity of hydroxyethyl cellulose in this application refers to the viscosity of a 2 wt% aqueous solution of hydroxyethyl cellulose, measured using a Grade H viscometer, method Clariant test method 7320.

The hydroxyethyl cellulose in the present application may be commercially available, for example, coilene TyloseHS30000YP2, coilene TyloseHS100000YP2, dow CELLOSIZE QP100MH, dow CELLOSIZE QP52000H, dow CELLOSIZE QP30000H, and the like; preferably the dow CELLOSIZE QP 52000H.

The inventor finds that when the composite thickener is used, the sagging phenomenon of the latex paint in the brushing process is reduced, the paint film is more uniform, the storage effect of the latex paint in a plateau area is improved, and the production process is easier to operate, because the polyacrylic thickener, which is used as an alkali swelling thickener, has good matching property with alkaline pure acrylic emulsion, forms a network high molecular polymer in a system and improves the consistency of the product, but anions contained in polyacrylic acid can obviously reduce the surface tension of the emulsion, and a large amount of air bubbles are introduced, so that the foaming phenomenon in the production process is serious, the production and filling are not facilitated, and air holes can be left on the surface of the paint film; the use of the cellulose can reduce the dosage of polyacrylic acid, improve the foaming phenomenon, utilize the active group on the cellulose molecule to act on each other and raise the emulsion viscosity, but the viscosity of the cellulose needs to be controlled strictly, when the viscosity is too big, the molecular weight of the cellulose is large, the low shear viscosity that can provide is apparent, but take place the orientation under the high-high shear viscosity, cause the pseudoplastic fluid viscosity to drop sharply, cause splash and sagging, otherwise the viscosity is too small, the thickening effect is not obvious; the polyurethane thickener utilizes the association-dissociation effect to improve the system viscosity, and contains hydrophobic groups to connect oil drops in the emulsion paint to form a three-dimensional structure, thereby making up the defect of the cellulose thickener under medium and high shear viscosity. The inventor finds in a great deal of practice that due to the fact that the temperature difference between the morning and the evening in plateau areas is large, the storage performance of the latex paint in high-temperature and low-temperature circulation can be guaranteed only when three thickening agents are in a certain proportion, when the proportion of the thickening agents is not proper, the situation that gaps of a network structure in a system are too small and water molecules are extruded out of a polymer structure can occur, and layering can occur; or due to an imbalance in lipophilicity between the thickeners, two phase separation can likewise occur.

In some preferred embodiments, the surfactant is selected from one or more of silicone surfactants, polyoxyethylene ether surfactants, fatty acid surfactants, and phosphate ester surfactants; more preferably, the surfactant is a mixture of a silicone surfactant and a polyoxyethylene ether surfactant; the weight ratio is 1: (1-3).

The organic silicon surfactant can be commercially available, such as BYK-023, BYK-065, BYK-066N, BYK-067, BYK-070, BYK-077 and BYK-085 which are produced by Pico chemistry; BYK-023 is preferred.

The polyoxyethylene ether surfactant herein may be commercially available, such as emulsifier OP-6, emulsifier OP-10, emulsifier TX-10, emulsifier NP-10, penetrant JFC, wetting agent X-405; preferred is wetting agent X-405.

The wetting agent X-405 in this application is TRITON X-405 manufactured by Dow chemical.

The term "softening agent" as used herein refers to a compound that softens the surface of oil droplets in latex paints and renders the paint droplets more susceptible to cross-linking when contacted by a brush.

In some preferred embodiments, the softening agent is 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate (CAS number: 25265-77-4).

The 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate in this application is Texanol ester produced by Istman chemistry.

The inventor finds that the specific surfactant and the specific softener are added into the latex paint, so that the dispersibility of each component in a system can be improved, the film forming temperature is reduced, the freeze-thaw stability of the latex paint can be greatly improved, and the production efficiency is improved, because the softener can be adsorbed on the surfaces of oil drops in the latex paint, the surface properties of the oil drops are changed, the oil drops are easy to combine into a film through mutual contact after being coated, however, the latex paint is frozen in a low-temperature environment in a plateau area, the oil drops are accumulated and pressed due to the expansion of ice crystal volumes, the oil drops are condensed, and the thawed oil drops cannot recover to the original shape; the polyoxyethylene ether surfactant can change the interface properties of each component in the emulsion paint, narrow the size distribution range of oil drops, uniformly disperse in an emulsion system, and reduce the extrusion force of ice crystals on the oil drops in icing by matching with a three-dimensional structure formed by a thickening agent and the blocking capability of a filler; the organosilicon surfactant can destroy the stability of bubbles in a system, improve the foaming phenomenon caused by the thickener, improve the production efficiency, disperse near oil drops due to the hydrophobic property, isolate water molecules, avoid the condensation of ice crystals near the oil drops, weaken the softening effect of the softener, avoid the condensation of the oil drops, and greatly improve the storage performance of the emulsion paint in a plateau area.

In some preferred embodiments, the antimicrobial aid is selected from a mixture of one or more of an antibacterial agent, a mold inhibitor, and a preservative.

In some embodiments, the antimicrobial agent is a metal ion antimicrobial agent; the metal ion antibacterial agent is selected from one or more of silver ion antibacterial agent, zinc ion antibacterial agent and copper ion antibacterial agent; preferably, the metal ion antibacterial agent is a silver ion antibacterial agent.

The silver ion antimicrobial agent herein may be commercially available, such as Silvadur930, BassfringerguarDB 7000, BassfringerguarD B6000, and the like.

The metal ion antibacterial mode is that the fungus cells can enrich metal ions, and the metal ions adsorbed on the surfaces of the fungi destroy the functions of cell membranes and enter the cells, so that certain cell components escape, interfere the metabolic process of the cells or interfere the functions of various enzymes, so that the cells lose the due biological functions, and finally die.

In some embodiments, the mold inhibitor is selected from the group consisting of biphenyl, o-phenylphenol, 2-pyridinethiol-1-zinc oxide, ammonium persulfate, calcium phosphate, p-chloro-m-dimethylphenol, tetrachloroisophthalonitrile, a mixture of one or more of p-chlorophenols; tetrachloroisophthalonitrile (CAS number: 1897-45-6) is preferred.

In some embodiments, the preservative is selected from the group consisting of benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, calcium propionate, salicylic acid, phenol, paraben, and a mixture of one or more of isothiazolones.

The term "isothiazolone" herein refers to isothiazolones and derivatives thereof, such as 5-chloro-2-methyl-4-isothiazolin-3-one, and the like.

Isothiazolones in this application are commercially available, for example, Kathon LXE produced by roman hass.

In some preferred embodiments, the antimicrobial assistant is a mixture of an antibacterial agent, a mildew preventive and a preservative, and the weight ratio of the antimicrobial assistant to the preservative is 1: (2-3): (1-3).
