Description
Technical Field
The invention belongs to the technical field of high polymer coatings, and particularly relates to a novel water-based matt stain-resistant ink-resistant ultraviolet curing coating and a preparation and use method thereof.
Background
China manufacturing 2025 vigorously pushes breakthrough and development of key fields, including ten fields such as new materials represented by water-based paints. The water paint is a coating taking water as a dispersion medium or solvent, and a film-forming substance is dissolved in water or dispersed in water. The water paint replaces paint, can effectively reduce the content of volatile organic compounds in the atmosphere, does not pollute the environment, is harmless to human bodies, and has the characteristics of good paint film flexibility, yellowing resistance and the like. However, the aqueous paint is rarely applied to floor coating because of high cost, difficult control of coating technology, and incapability of meeting standard requirements on film hardness, wear resistance and the like, and basically, the oil-based ultraviolet curing coating is used. The current market oily ultraviolet curing coating has the defects of strong smell, large paint film shrinkage, brittle paint film, difficult extinction and the like. Particularly, the problems of high viscosity, easy thickening after recycling, no leveling, difficult drying and large residual taste exist in the ultra-low matte coating product, and the problems form obstacles for practical production and application.
At present, the problems of low solid content, poor filling, easy whitening of a paint film, no water resistance, easy cracking, easy paint stripping, no scratch resistance and the like exist in few water-based ultraviolet curing coatings on the market, and the market demand cannot be met. Therefore, the development, production and popularization of water-based paints are the mainstream directions of the coating industry at present. Although some enterprises in the market have introduced decorative boards, furniture and floors coated with water-based paints, the pollution resistance of the decorative boards, furniture and floors cannot be detected by blue ink, mainly because the blue ink contains high-boiling organic solvent and is easy to permeate paint films, the market demand for the pollution-resistant functional paint is increasing.
Disclosure of Invention
The invention aims to overcome the defects of the existing coating and provide a novel water-based matt stain-resistant ink-resistant ultraviolet curing coating.
The invention also aims to provide a preparation method of the novel water-based matt stain-resistant ink-resistant ultraviolet-curable coating.
Another object of the invention is to provide a method for using the novel water-based matt stain resistant ink resistant UV-curable coating.
In order to achieve the purpose, the invention adopts the following technical scheme:
a novel water-based matt stain-resistant ink-resistant ultraviolet curing coating comprises the following components in parts by weight:
the novel water-based matt stain resistant ink resistant ultraviolet curing coating is characterized in that the water-based resin A is 6-functional aliphatic polyurethane acrylate and has a solid content of 45%, and the water-based resin B is 10-functional aliphatic polyurethane acrylate and has a solid content of 80%. The 6-functional aliphatic polyurethane acrylate has the characteristics of high hardness, yellowing resistance and good toughness, the 10-functional aliphatic polyurethane acrylate contains a large number of urethane bonds, which is beneficial to forming hydrogen bonds between macromolecular chains, can improve the crosslinking density and film forming speed of a coating film, and has the characteristics of relatively balanced hardness, flexibility, fast curing and toughness, and the 10-functional aliphatic polyurethane acrylate has good transparency, surface leveling effect and glossiness in appearance, has excellent adhesion performance, and can be used for improving the wear resistance of a coating.
The matte powder A is fumed silica micro powder with the fineness of 3-5 microns, the matte powder B is spherical micro powder with the fineness of 3-6 microns, and the hand feeling powder is hollow spherical elastomer micro powder with the fineness of 3-5 microns. In addition, the granular form of the fumed silica has good flowability and compressibility, so that the surface can be leveled to form a coating with uniform thickness after coating. The hard nature of fumed silica itself can further improve the abrasion and scratch resistance of the coating formed after application. The particle size of the fumed silica micro powder is 3-5 micrometers, the particle size of the spherical micro powder is 3-6 micrometers, and the surface of the coating can form a relatively rough surface through the particle size difference between the spherical micro powder and the fumed silica, so that light in the environment is subjected to diffuse reflection, the glossiness of the surface of the coating is reduced, and the matte surface effect is achieved. The hollow spherical elastomer micro powder has the main function of increasing the hardness and the scratch resistance of the coating.
The material A is hydroxyl-containing modified organic silicon polyacrylate liquid with the solid content of 30 percent, and the material B is hydroxyl-containing polyether modified acrylic acid functional group dimethyl siloxane liquid with the solid content of 96 percent. The combination of the functional groups of the aliphatic polyurethane acrylate with different functionalities can improve the stability of a system, promote the leveling of a coating on the surface of a coated object, and improve the mechanical strength by mutually bonding the different functional groups of the aliphatic polyurethane acrylate with adjacent similar molecules, hydroxyl-containing modified organosilicon polyacrylate liquid and hydroxyl polyether modified acrylic functional polydimethylsiloxane liquid. In addition, due to the hydrogen bond action among the aliphatic polyurethane acrylate molecules with different functionalities, the molecular chain of the aliphatic polyurethane acrylate forms a crosslinking reaction with the hydroxyl-containing modified organic silicon polyacrylate liquid and the hydroxyl-containing polyether modified acrylic acid functional group dimethyl siloxane liquid, and the crosslinking reaction is mutually crosslinked to form a network structure, so that the coating cured by the coating can slide for a certain distance along the direction of the force when the coating is subjected to the friction force, and the toughness of the coating is enhanced. Because the molecular chain of the aliphatic polyurethane acrylate and the hydroxyl-containing modified organic silicon polyacrylate liquid and the hydroxyl-containing polyether modified acrylic acid functional group dimethyl siloxane liquid are low in crosslinking speed and are not easy to thicken, the thickening phenomenon caused by partial polymerization of the coating before use is avoided, and the construction recoating and reworking are easy. On the other hand, silicon groups in the hydroxyl-containing modified organic silicon polyacrylate liquid and the hydroxyl-containing polyether modified acrylic functional polydimethylsiloxane solution can be directionally arranged on the surface of the coating in the process of forming the coating by the coating, so that the hydrophobic property, the crosslinking density and the surface finish of the coating are further improved. The hydroxyl-containing polyether modified acrylic acid functional polydimethylsiloxane solution can also improve the leveling property of the coating, so that the surface of the coating is flat and free of defects.
The wax emulsion is polyethylene wax slurry with the fineness of 3-6 microns, and the solid content is 45%. The polyethylene wax syrup can enhance wetting and dispersion of the coating agglomerates, resist caking, and improve flowability. The polyethylene wax slurry drifts to the surface of the coating film in the film forming process, is uniformly dispersed, generates an extinction effect, forms a wax protection layer on the coating film, reduces the friction coefficient, has better hydrophobic property of the wax-containing coating film, enables the coating to have good wear resistance and touch feeling by adding the polyethylene wax slurry, changes the stress direction of the coating and improves the scratch resistance of the coating.
The dispersing agent is an acidic group copolymer, the solid content is 100%, and the acidic group copolymer is used for improving the compatibility of each component in the solution, so that each component can be uniformly dispersed in the coating.
The hydrophobic agent is pentaerythritol oleate with the solid content of 99 percent. The pentaerythritol oleate can migrate to the surface of a coating to form a protective film in the drying process of the coating, has good wear-resistant lubricating effect due to the fact that a molecular structure contains ester groups with high activity, can provide wear-resistant and scratch-resistant performance on the surface of a coating, can reduce the surface tension of the coating, can improve the surface hydrophobic performance and the anti-sticking and anti-fouling performance of the coating, and can effectively reduce the permeability of blue-black ink and stains.
The defoaming agent is polyether polysiloxane transparent liquid, the solid content is 100%, and the addition of the polyether polysiloxane transparent liquid can prevent bubbles from being generated in a system and improve the adhesion of a coating film.
The pH regulator is 2-amino-2-methyl-1-propanol, and the solid content is 95%. 2-amino-2-methyl-1-propanol has low odor, reduces volatile organic compounds in the coating, and 2-amino-2-methyl-1-propanol can be used as a dispersant at the same time, can prevent the agglomeration of the coating, can reduce the usage amount of the acid group copolymer, reduce the generation of bubbles, effectively adjust the pH value of the coating, achieve the optimal use environment,
the thickening agent is a nonionic polyurethane solution, the solid content is 60%, and the nonionic polyurethane solution can greatly improve the adhesive strength, water resistance and other properties of a paint film.
The leveling agent is polyether modified polydimethylsiloxane, and the solid content is 100%. The polyether modified dimethyl siloxane can reduce the surface tension of the coating, has excellent shrinkage cavity resistance, good substrate wetting and leveling promoting effects, enables the coating to be leveled on the substrate better, and prevents the formation of a coating with uneven thickness.
The hydrophilic chain extender comprises dimethylolpropionic acid, dimethylolbutyric acid or ethylenediamine. Polar groups such as hydroxyl, carboxyl and the like in dimethylolpropionic acid and dimethylolbutyric acid can mutually attract hydroxyl groups in hydroxyl-containing modified organic silicon polyacrylate liquid and hydroxyl-containing polyether modified acrylic acid functional polydimethylsiloxane solution to form hydrogen bonds, so that a paint film can be more firmly attached to the surface of an object to be coated. The amino in the ethylenediamine reacts with the ester group in the aliphatic polyurethane acrylate to form a urea bond, so that the crosslinking effect of a hard segment of a molecular chain segment is enhanced, a higher crystal density is formed, the permeation difficulty of water molecules is increased, and a paint film of the water-based paint has good stain resistance and ink permeation resistance.
The photoinitiator A is 2-hydroxy-2-methyl-1-phenyl acetone or 2-hydroxy-2-methyl-1-phenyl-1-acetone, and the photoinitiator B is 1-hydroxycycloethylphenyl ketone or 2, 4, 6-trimethylbenzoyl-diphenylphosphine oxide. In the matte coating, the powder lot easily causes the thickness of a paint film layer to be larger, a high-efficiency ultraviolet initiator is needed to completely cure the paint film layer, the oligomer and the dispersant in the system are promoted to be rapidly converted from a liquid state to a solid state, the light active groups interact, the absorption of light energy can be improved, the activity is increased, and the yellowing property of the product is overcome to a certain extent. The photoinitiator is prepared from a photoinitiator A and a photoinitiator B according to the weight ratio of 2-4: 2-4, and adopting a compound photoinitiator A and a photoinitiator B for initiating the crosslinking of the polymer.
The auxiliary initiator is one of tertiary amine acrylate, alkyl hydroxylamine and dimethylaminobenzoate, preferably tertiary amine acrylate which is transparent liquid. The photoinitiator aid is a component which has high initiation activity and can participate in curing reaction without migration, and the photoinitiator has an initiator aid group on the structure, so that the toxicity and the migration of the traditional photoinitiator are reduced. The tertiary amine acrylate has the characteristic of yellowing resistance, and meanwhile, the tertiary amine can provide a large amount of active hydrogen, so that oxygen inhibition is effectively avoided, the curing speed is improved, and the using amount of a photoinitiator can be reduced.
A preparation method of a novel water-based matt stain-resistant ink-resistant ultraviolet curing coating is characterized by comprising the following steps:
1) firstly, sequentially adding and mixing water-based resin A, a dispersing agent, a defoaming agent, a wax emulsion, matting powder A, matting powder B, hand feeling powder, a material A and a material B, and a hydrophilic chain extender under the stirring at the rotating speed of 300-450 revolutions per minute, and then stirring at the rotating speed of 700-900 revolutions per minute for 10-15 minutes to obtain an initial-stage mixture;

The amount of the 10-functional aliphatic urethane acrylate added to the aqueous resin B is 22 parts, and when the amount of the 10-functional aliphatic urethane acrylate added is less than 15 parts, there is a problem that curability and heat resistance of the coating film are poor. The matting powder A is fumed silica micropowder with the fineness of 3 microns, the matting powder B is spherical micropowder with the fineness of 5 microns, and the matte effect is generated on the surface due to the particle size difference between the fumed silica micropowder and the spherical micropowder.

In the above example 1, a method for preparing a novel aqueous matt, stain-resistant, ink-resistant uv-curable coating is characterized by comprising the following steps:
1) firstly, sequentially adding and mixing 6-functional aliphatic polyurethane acrylate, acid group copolymer, polyether polysiloxane transparent liquid, polyethylene wax slurry, fumed silica micro powder, spherical micro powder, hollow spherical elastomer micro powder, hydroxyl-containing modified organic silicon polyacrylate liquid, hydroxyl-containing polyether modified acrylic acid functional aggregate dimethyl siloxane liquid and dimethylolpropionic acid under stirring at the rotating speed of 300-450 revolutions per minute, and then stirring at the rotating speed of 700-900 revolutions per minute for 10-15 minutes to obtain a primary-stage mixture;
2) and then adding 2-hydroxy-2-methyl-1-phenyl acetone, 1-hydroxy ethyl phenyl ketone and tertiary amine acrylate into the initial mixture, and stirring and dissolving at the temperature of 60-70 ℃ at the rotating speed of 700-900 rpm.

In the above example 2, the aqueous resin a is 6-functional aliphatic urethane acrylate containing 45% of solid content, the aqueous resin B is 10-functional aliphatic urethane acrylate containing 80% of solid content, the matting powder a is fumed silica fine powder with fineness of 5 microns, the matting powder B is spherical fine powder with fineness of 4 microns, the hand feeling powder is hollow spherical elastomer fine powder with fineness of 5 microns, the material a is hydroxyl-containing modified organosilicon polyacrylate liquid containing 30% of solid content, the material B is hydroxyl-containing polyether modified acrylic functional agglomerated dimethylsiloxane liquid containing 96% of solid content, the wax emulsion is polyethylene wax slurry containing 45% of solid content with fineness of 4 microns, the dispersing agent is acid group copolymer containing 100% of solid content, the hydrophobic agent is pentaerythritol oleate containing 99% of solid content, the defoaming agent is polyether polysiloxane transparent liquid containing 100% of solid content, the pH adjusting agent is 2-amino-2-methyl-1-propanol containing 95% of solid content, the thickening agent is a nonionic polyurethane solution with the solid content of 60%, the flatting agent is polyether modified polydimethylsiloxane with the solid content of 100%, the hydrophilic chain extender is dimethylolpropionic acid, the photoinitiator A is 2-hydroxy-2-methyl-1-phenyl acetone, the photoinitiator B is 2, 4, 6-trimethylbenzoyl-diphenyl phosphine oxide, and the auxiliary initiator is dimethylaminobenzoate.

The matting powder A is fumed silica micro powder with the fineness of 5 microns, the matting powder B is spherical micro powder with the fineness of 4 microns, and due to the fact that the fumed silica micro powder and the spherical micro powder are different in granularity, a matte effect is generated on the surface.

In the above example 2, a method for preparing a novel aqueous matt stain resistant ink resistant uv curable coating is characterized by comprising the following steps:
1) firstly, sequentially adding and mixing 6-functional aliphatic polyurethane acrylate, acid group copolymer, polyether polysiloxane transparent liquid, polyethylene wax slurry, fumed silica micro powder, spherical micro powder, hollow spherical elastomer micro powder, hydroxyl-containing modified organic silicon polyacrylate liquid, hydroxyl-containing polyether modified acrylic acid functional aggregate dimethyl siloxane liquid and dimethylolpropionic acid under stirring at the rotating speed of 300-450 revolutions per minute, and then stirring at the rotating speed of 700-900 revolutions per minute for 10-15 minutes to obtain a primary-stage mixture;

3) and sequentially adding 10 functional aliphatic polyurethane acrylate, pentaerythritol oleate, 2-amino-2-methyl-1-propanol, a non-ionic polyurethane solution and polyether modified polydimethylsiloxane into the mixture, stirring at the rotating speed of 700-900 rpm for 10-15 minutes, and filtering to remove impurities to obtain the novel water-based matt stain-resistant ink-resistant ultraviolet curing coating.
In the above example 3, the aqueous resin a is 6-functional aliphatic urethane acrylate containing 45% of solid content, the aqueous resin B is 10-functional aliphatic urethane acrylate containing 80% of solid content, the matting powder a is fumed silica fine powder with 4 micron fineness, the matting powder B is spherical fine powder with 3 micron fineness, the handle powder is hollow spherical elastomer fine powder with 4 micron fineness, the material a is hydroxyl-containing modified organosilicon polyacrylate liquid containing 30% of solid content, the material B is hydroxyl-containing polyether modified acrylic functional agglomerated dimethylsiloxane liquid containing 96% of solid content, the wax emulsion is polyethylene wax slurry containing 45% of solid content with 4 micron fineness, the dispersant is acid group copolymer containing 100% of solid content, the hydrophobic agent is pentaerythritol oleate containing 99% of solid content, the defoaming agent is polyether polysiloxane transparent liquid containing 100% of solid content, the pH adjusting agent is 2-amino-2-methyl-1-propanol containing 95% of solid content, the thickening agent is a nonionic polyurethane solution with the solid content of 60%, the flatting agent is polyether modified polydimethylsiloxane with the solid content of 100%, the hydrophilic chain extender is dimethylolbutyric acid, the photoinitiator A is 2-hydroxy-2-methyl-1-phenyl-1-acetone, the photoinitiator B is 2, 4, 6-trimethylbenzoyl-diphenyl phosphine oxide, and the auxiliary initiator is alkylhydroxylamine.
In example 3, the amount of the 6-functional aliphatic urethane acrylate added to the aqueous resin a was 32 parts by weight, and when the amount is less than 25 parts by weight, the adhesion of the coating material was weakened, which affected the curability of the coating film. The amount of 10-functional aliphatic urethane acrylate added to the aqueous resin B is 30 parts, and when it exceeds 30 parts, excessive curing density may cause cracking and yellowing in the coating film. The matting powder A is fumed silica micropowder with fineness of 4 microns, the matting powder B is spherical micropowder with fineness of 3 microns, and the matte effect is generated on the surface due to the particle size difference between the fumed silica micropowder and the spherical micropowder.
