Description

Water-based fluorine-containing acrylic acid copolymer emulsion for antibacterial ink and preparation method and application thereof
Technical Field
The invention belongs to the technical field of water-based ink, and particularly relates to water-based fluorine-containing acrylic acid copolymer emulsion for antibacterial ink, and a preparation method and application thereof.
Background
The ink is an important substance for forming graphic and text information in the printing process, and is generally a uniform mixture with certain flowing property and adhesive property formed by mixing substances such as color bodies, binders, fillers, additives and the like through a certain process. The traditional ink is gradually eliminated due to the problems of harmful solvent content, overproof VOC, easy environmental pollution and the like, the traditional oil-based ink is gradually replaced by the water-based ink along with the enhancement of the environmental awareness of people, but various additives added in the water-based ink are not easy to resist and inhibit bacteria, bacteria and various microorganisms are easily generated after printing, and potential harm is brought to the health of a human body and the use environment. Therefore, water-based inks having antibacterial properties have been a focus of attention.
Currently, antibacterial agents used in antibacterial inks mainly include inorganic antibacterial agents and organic antibacterial agents. The inorganic antibacterial agent mainly comprises metal ion components and an inorganic carrier, but the application of the inorganic antibacterial agent in the ink has some problems, such as poor compatibility of the antibacterial material and the ink components, uneven dispersion in an ink system, easy generation of precipitate and long-time flowing state; most of the organic antibacterial agents are insoluble in water, have poor compatibility with water-based ink, and are sensitive to light and temperature. Therefore, a water-based ink which has high-efficiency antibacterial performance, good dispersibility, difficult precipitation and migration and no toxic or side effect on a human body is needed.
Disclosure of Invention
The present invention has been made to solve at least one of the above-mentioned problems occurring in the prior art. Therefore, the invention provides a water-based fluorine-containing acrylic acid copolymer emulsion for antibacterial ink, and a preparation method and application thereof.
According to one aspect of the invention, the invention provides a water-based fluorine-containing acrylic acid copolymer emulsion, which is prepared from the following raw materials in parts by weight: 60-70 parts of functional monomer, 30-40 parts of acrylic monomer, 10-20 parts of fluorine-containing monomer, 1-2 parts of first nonionic emulsifier, 1-2 parts of second nonionic emulsifier, 1-2 parts of viscosity regulator, 0.5-1 part of initiator and 20-25 parts of water;
the functional monomer comprises lauryl methacrylate, glycidyl methacrylate, dodecafluoroheptyl methacrylate, tridecafluoro-n-octyl methacrylate and styrene;
the fluorine-containing monomer comprises heptadecafluorodecyltrimethoxysilane and heptadecafluorodecyltriethoxysilane;
the acrylic monomer includes methacrylic acid, methyl methacrylate, ethyl methacrylate, and ethyl ethacrylate.
In some embodiments of the present invention, the mass ratio of methacrylic acid, methyl methacrylate, ethyl methacrylate and ethyl ethacrylate is (30-40): (25-35): (20-30): (15-20). Methacrylic acid is matched with methyl methacrylate and ethyl methacrylate to wrap a fluorine-containing monomer for reaction and then is subjected to a connecting action to form a fluorine-containing monomer-acrylate compound, and because a part of acrylate chemical bonds are opened, acrylic acid needs to be replenished again for connection to form a macromolecular group with a certain molecular weight. If the amount of the methacrylic acid is too small, a molecular group with a certain molecular weight cannot be effectively produced, the molecular weight of the fluorine-containing monomer, namely the acrylate compound, is reduced, the boiling point is reduced, and more waste liquid is generated; if the amount of the methacrylic acid is too much, the molecular weight of the fluorine-containing monomer, namely the acrylate compound is too large, so that molecular agglomeration is caused, large particles are easy to generate, and the product quality is reduced. If the acrylic ester is unreasonable in collocation, self-crosslinking is easy to occur, so that the fluorine-containing monomer cannot be well connected with an acrylic ester polymerization system, the crosslinking proportion with the fluorine-containing monomer is small, the material cannot be completely utilized, waste is caused, and therefore the proportion of the acrylic ester monomers is strictly controlled, the later reaction can be controlled, and an expected product can be obtained.
In some embodiments of the invention, the lauryl methacrylate, glycidyl methacrylate, dodecafluoroheptyl methacrylate, tridecafluoro-n-octyl methacrylate and styrene are in a mass ratio of (30-40): (10-20): (10-20): (5-10): (2-5). Lauryl methacrylate can effectively provide a three-dimensional space frame structure after emulsion is solidified, meanwhile, lauryl methacrylate contains a long chain, the rigidity of acrylic monomers can be regulated, the toughness of ink is enhanced, frames formed by other acrylic ester connecting fluorine monomers are poorer in weather resistance than the space frames formed by lauryl methacrylate, however, if the dosage of lauryl methacrylate is too much, the rigidity can be enhanced, irregular crystals can be easily generated on a paperboard, if the dosage is too little, the formed space frames are less, the space frame structure cannot be effectively provided, or the generated structure is a loose structure, a large-area structure is not generated, and the performance of ink is further influenced. The dodecafluoroheptyl methacrylate is an oil-soluble surfactant, the surface tension of acrylic acid is mainly increased, and the effect of the dodecafluoroheptyl methacrylate is more obvious than that of a water-soluble surfactant.
In some embodiments of the invention, the mass ratio of heptadecafluorodecyltrimethoxysilane to heptadecafluorodecyltriethoxysilane is (65-75): (25-35).
In some embodiments of the invention, the viscosity modifier is selected from at least one of ethanol, isopropanol, or glycerol.
In some embodiments of the invention, the viscosity modifier is prepared from (45-50): (40-45): 10 of ethanol, isopropanol and glycerol. The ethanol has the effects of improving the leveling property and reducing the surface tension of the aqueous solution, and if the ethanol is used in too small amount, the leveling property is poor, the surface tension is too large, the surface cannot be completely spread when the paper is used, the agglomeration is easy to generate, and the use is not facilitated; if the amount of the ethanol is too much, the leveling property is strong, the surface tension is too small, the permeability is strong, the ethanol can easily permeate the bottom of paper, and other components staying on the surface are less, so that waste is caused. The isopropanol has the function of adjusting surface tension, and the problem that after part of ethanol is evaporated, the surface tension of the solution suddenly rises to cause that the diffusion speed suddenly drops during laying and leveling, so that the tail end of part of the solution is agglomerated can be avoided because the boiling point of the ethanol is lower than that of the isopropanol, the evaporation point is lower, and the boiling point of the isopropanol is higher; if the dosage of the isopropanol is too small, the solution cannot be effectively paved after part of ethanol is evaporated, and the diffusion speed is reduced; if the dosage of the isopropanol is too much, the solution permeability is stronger, the ink staying on the surface of the paper is less, and the waste is easily caused. The glycerol has the function of reducing the evaporation capacity of the solution in a certain area, so that water in the solution can be effectively paved on paper in a certain time, and the solution has a certain reaction time on the paper; if the consumption of the glycerol is too small, the evaporation amount of water in the solution is increased, and other materials on the paper have insufficient reaction time, so that the material waste is caused; if the consumption of the glycerol is too much, the evaporation capacity of water in the solution is reduced, the humidity on the paper is too high, the drying time of the paper is long, the drying energy consumption is high, and the production benefit is low.
In some embodiments of the invention, the first non-ionic emulsifier is selected from one or both of sorbitan monooleate or sucrose fatty acid ester.
In some preferred embodiments of the present invention, the first nonionic emulsifier is prepared by mixing, in mass ratio (40-50): (50-60) sorbitan monooleate and sucrose fatty acid ester. Sorbitan monooleate is used as a fluorine-containing monomer for primary emulsification in a solution with the compounding temperature of 45-50 ℃ and is used as a chemical bond linking emulsifying and wrapping emulsifier, and sucrose fatty acid ester is used as a fluorine-containing monomer for post-emulsification or partial incomplete emulsification for emulsifying and wrapping after the compounding temperature of 50-55 ℃. The two emulsifiers are used because a plurality of acrylic monomers are used and the emulsification efficiency is different at a specific temperature, and the use of the two emulsifiers can increase the emulsification efficiency.
In some embodiments of the present invention, the second nonionic emulsifier is selected from one or both of sodium lauryl sulfate or fatty alcohol polyoxyethylene ether.
In some embodiments of the invention, the second non-ionic emulsifier is prepared from (30-40): (60-70) sodium dodecyl sulfate and fatty alcohol-polyoxyethylene ether.
In some embodiments of the invention, the initiator is ammonium persulfate.
The invention also provides a preparation method of the aqueous fluorine-containing acrylic acid copolymer emulsion, which comprises the following steps:
s1: mixing and dispersing a functional monomer, a first nonionic emulsifier and a viscosity regulator to obtain a first pre-emulsion; mixing and dispersing an acrylic monomer, a fluorine-containing monomer, a second non-ionic emulsifier, an initiator and water to obtain a second pre-emulsion;
s2: and under the heating condition, dropwise adding the first pre-emulsion into the second pre-emulsion, carrying out heat preservation reaction after dropwise adding is finished, cooling after the reaction is finished, and then adjusting the alkalinity to 7.5-8.0 to obtain the aqueous fluorine-containing acrylic acid copolymer emulsion.
In some embodiments of the present invention, in step S1, the temperature at which the functional monomer, the first nonionic emulsifier, and the viscosity modifier are mixed and dispersed is 45 to 55 ℃.
In some embodiments of the present invention, in step S1, the temperature at which the acrylic monomer, the fluorine-containing monomer, the second non-ionic emulsifier, the initiator and the water are mixed and dispersed is 35 to 45 ℃.
In some embodiments of the present invention, in step S2, an alkaline regulator is used for regulating the alkalinity, and the alkaline regulator is ammonia water with a mass concentration of 28% to 35%.
In some embodiments of the invention, the temperature of the heating in step S2 is 60 to 65 ℃.
In some embodiments of the present invention, in step S2, the dropping time is 1.5 to 2.0 hours.
In some embodiments of the invention, the aqueous fluoroacrylic copolymer emulsion has a viscosity of from 500 to 700mPa · s and a molecular weight of from 1000 to 1500.
The invention also provides application of the water-based fluorine-containing acrylic acid copolymer emulsion in printing ink.
According to a preferred embodiment of the present invention, at least the following advantages are provided:
in the aqueous fluorine-containing acrylic acid copolymer emulsion, water is a disperse phase, the fluorine-containing monomer is a core material of the aqueous antibacterial ink and is used as a main medium for resisting and inhibiting bacteria, various acrylic acids are matched for use, the acrylic acid is coated on the surface of paper microscopically through an emulsification process, the fluorine-containing monomer is attached to the surface of the paper through acrylate, the oxidizing property of fluorine ions is high, and common bacterial microorganisms cannot move in a medium with strong oxidizing property, so that the effects of resisting and inhibiting bacteria are achieved.
