Description

Technical Field

[0001] The present invention relates to the field of glass, in particular to corrosion-resistant glass and a preparation method thereof. Background Art

[0002] Modern life is inseparable from glass products. Glass is usually an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals as the main raw materials, and a small amount of auxiliary raw materials. Due to its transparency and beauty, it is widely used in outdoor places such as windows, solar tubes, photovoltaic panels, windshields and greenhouses.

[0003] However, outdoor places, especially the seaside, are very prone to salt spray corrosion on glass, which can cause the glass surface to become rough, reduce transparency, and even reduce strength, affecting its use; and when the glass is exposed to ultraviolet rays for a long time, the ultraviolet rays will cause chemical reactions on the glass surface, resulting in cracks and fissures in the glass. Therefore, this application introduces a corrosion-resistant glass with aging resistance and a preparation method thereof. Summary of the Invention

[0004] A corrosion-resistant glass is prepared by polymerizing methyl methacrylate, ethylene glycol acetoacetate, butyl acrylate, and 1-allyl-4-(trifluoromethyl)benzene, mixing the mixture with 4-bromo-1-butene, irradiating the mixture with light, coating the mixture on a functionalized glass plate, and curing the mixture.

[0005] The functionalized glass plate is prepared by sequentially reacting a glass plate with trimethoxy(thiophene-2-yl)silane, thiophene, 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and 4-dimethylaminobenzonitrile.

[0006] A method for preparing corrosion-resistant glass, the method mainly comprising the following preparation steps:

[0007] (1) Ferric chloride and chloroform are mixed uniformly in a mass ratio of 1:9 to 9.4 to prepare a ferric chloride solution; thiophene, 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and chloroform are mixed in a mass ratio of 5 to 7:1:13, and ultrasonicated for 5 to 7 minutes to prepare a thiophene mixed solution; under nitrogen protection, a pre-modified glass plate is immersed in the thiophene mixed solution, and a ferric chloride solution 3 to 4 times the mass of the thiophene mixed solution is added at a uniform rate within 4 to 6 minutes, and the glass plate is allowed to stand for 3 to 5 minutes, and the pre-modified glass plate is taken out until no liquid drops, and the glass plate is allowed to stand for 46 to 50 hours at 30 to 40°C under nitrogen protection, and washed with chloroform 3 to 5 times, and vacuum dried at -10 to 0°C for 22 to 26 hours to prepare a modified glass plate;

[0008] (2) Polyacrylate emulsion, 4-bromo-1-butene, 4-methoxythiophenol and lithium formate are mixed in a mass ratio of 1:0.08-0.12:0.25-0.35:0.08-0.12, stirred at 600-800 r / min, argon protection, 427 nm LED light for 22-26 h, and evenly applied on a functionalized glass plate with a thickness of 0.4-0.6 mm. The mixture is allowed to stand at 55-65 ° C under argon protection for 8-12 h, washed with deionized water and ethanol for 3-5 times in sequence, and vacuum dried at -10-0 ° C for 22-26 h to obtain corrosion-resistant glass.

[0009] As an optimization, the pre-modified glass plate in step (1) is prepared by mixing a glass plate, trimethoxy(thiophene-2-yl)silane and isopropyl alcohol in a mass ratio of 1:0.14-0.16:10-12, adjusting the pH to 3.8-4.2 with a 0.1 mol / L acetic acid solution, stirring at 85-95°C and 200-300 r / min for 5-7 hours, filtering, washing with deionized water for 3-5 times, and drying at 90-100°C for 2-4 hours.

[0010] As an optimization, the glass plate is ordinary flat glass with a thickness of 5 mm, and the purchase manufacturer is Handan Mina Trading Co., Ltd.

[0011] As an optimization, the polyacrylate emulsion in step (2) is prepared by taking 4 to 6 parts of initiator solution, 14 to 16 parts of emulsifier solution and 12 to 14 parts of mixed monomers by mass, mixing the emulsifier solution, 10% of the initiator solution and 10% of the mixed monomers, stirring at 80 to 90° C., 300 to 500 r / min, under nitrogen protection for 14 to 16 minutes, adding the remaining initiator solution and mixed monomers at a uniform rate within 10 to 14 minutes, and continuing to stir for 3 to 5 hours.

[0012] As an optimization, the initiator solution is prepared by uniformly mixing ammonium persulfate and deionized water in a mass ratio of 1:350-370.

[0013] As an optimization, the emulsifier solution is prepared by uniformly mixing sodium lauryl sulfate, alkylphenol polyoxyethylene ether and distilled water in a mass ratio of 2:1:140-160.

[0014] As an optimization, the mixed monomer is prepared by mixing methyl methacrylate, ethylene glycol acetoacetate, butyl acrylate and 1-allyl-4-(trifluoromethyl)benzene in a mass ratio of 5-7:1.5-2.5:4-6:1.5-2.5.

[0015] As an optimization, the functionalized glass plate in step (2) is prepared by mixing 4-dimethylaminobenzonitrile and zinc chloride in a mass ratio of 1:0.04-0.06, grinding the mixture to 90-110 mesh, and evenly spreading the mixture on the surface of the modified glass plate with a thickness of 0.4-0.6 mm. The mixture is allowed to stand at 290-310° C. for 46-50 h, washed with ethanol for 3-5 times, and vacuum dried at -10-0° C. for 22-26 h.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When preparing the corrosion-resistant glass, the present invention comprises the following steps: reacting a glass plate with trimethoxy(thiophene-2-yl)silane, thiophene, 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and 4-dimethylaminobenzonitrile in sequence to prepare a functionalized glass plate; polymerizing methyl methacrylate, ethylene glycol acetoacetate methacrylate, butyl acrylate and 1-allyl-4-(trifluoromethyl)benzene, mixing the mixture with 4-bromo-1-butene, irradiating the mixture with light, coating the mixture on the functionalized glass plate and solidifying the mixture to prepare the corrosion-resistant glass.

[0018] First, the glass plate is reacted with trimethoxy(thiophene-2-yl)silane, thiophene, 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and 4-dimethylaminobenzonitrile in sequence to produce a functionalized glass plate. The glass plate is then reacted with trimethoxy(thiophene-2-yl)silane, thiophene and 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile in sequence to form a polythiophene polymer on the glass surface. Polythiophene is a polymer compound with good conductivity. Polythiophene can effectively conduct static charge, avoid static electricity accumulation, and improve the antistatic ability of the material. The glass plate is then reacted with 4-dimethylaminobenzonitrile to form a triazine ring, which forms a stable conjugated six-membered ring with triazine through hydrogen bonding. Triazine can absorb ultraviolet light, convert the light into heat energy and release it, achieving an aging-resistant effect. The conjugated six-membered ring formed by hydrogen bonding with triazine also has the effect of absorbing ultraviolet light, and works together with the triazine structure to enhance the aging resistance of the material.

[0019] Secondly, methyl methacrylate, ethylene glycol methacrylate acetoacetate, butyl acrylate and 1-allyl-4-(trifluoromethyl)benzene are polymerized, and then mixed with 4-bromo-1-butene, exposed to light, coated on a functionalized glass plate, and cured to produce corrosion-resistant glass; methyl methacrylate, ethylene glycol methacrylate acetoacetate, butyl acrylate and 1-allyl-4-(trifluoromethyl)benzene are polymerized to introduce fluorine groups. The fluorine atoms have extremely strong electronegativity and can form a tightly arranged fluorine atom layer to provide chemically inert protection. The strong adsorption effect and small atomic radius of fluorine atoms enable fluorine atoms to be tightly arranged around carbon atoms to form a protective barrier, thereby improving the corrosion resistance of the material. The aromatic trifluoromethyl group can react with olefins under light to introduce chlorine groups, which react with tertiary olefins on the glass plate. Amines react to form quaternary ammonium salts. Quaternary ammonium salts carry a positive charge and can be firmly adsorbed on the negatively charged bacterial cell surface through electrostatic attraction. After adsorbing to the bacterial surface, the quaternary ammonium salt inserts the hydrophobic group into the lipid layer, changing the permeability of the cell membrane, destroying the membrane structure, and causing leakage of intracellular substances; it can also interfere with the proton pump protein on the bacterial cell membrane, causing it to degrade or denature, affecting the cell's material transport and energy metabolism, and ultimately leading to the death of the bacteria, achieving an antibacterial effect. In addition, the quaternary ammonium salt cation can form a conductive layer on the material surface, increasing the mobility of the charge on the material surface, thereby reducing the surface resistance and allowing the static charge to dissipate faster. It can also react with the negative charge on the material surface to reduce the surface charge density, balance the charge distribution on the material surface, and achieve an antistatic effect.

[0033] Comparative Example 1:

[0034] The difference between the preparation method of the corrosion-resistant glass of Comparative Example 1 and Example 2 lies in the difference in step (1). Step (1) is modified as follows: a glass plate with a thickness of 5 mm, trimethoxy(thiophene-2-yl)silane and isopropyl alcohol are mixed in a mass ratio of 1:0.15:11, the pH is adjusted to 4 with a 0.1 mol / L acetic acid solution, the mixture is stirred at 90°C and 250 r / min for 6 h, filtered, washed with deionized water 4 times, and dried at 95°C for 3 h to obtain a pre-modified glass plate; ferric chloride and chloroform are mixed uniformly in a mass ratio of 1:9.2 to obtain a ferric chloride solution.

[0035] Comparative Example 2:

[0036] The preparation method of the corrosion-resistant glass of Comparative Example 2 differs from that of Example 2 only in that the glass plate is not modified. The remaining steps are the same as those of Example 2.

[0037] Comparative Example 3:

[0038] The difference between the preparation method of the corrosion-resistant glass of Comparative Example 3 and Example 2 lies in the difference in step (2). Step (2) is modified as follows: ammonium persulfate and deionized water are mixed uniformly in a mass ratio of 1:360 to prepare an initiator solution; sodium lauryl sulfate, alkylphenol polyoxyethylene ether and distilled water are mixed uniformly in a mass ratio of 2:1:150 to prepare an emulsifier solution; methyl methacrylate, ethylene glycol acetoacetate, butyl acrylate and 1-allyl-4-(trifluoromethyl)benzene are mixed in a mass ratio of 6:2:5:2 to prepare a mixed monomer; 5 parts of the initiator solution and 15 parts of the emulsifier solution are taken by mass.

The remaining initiator solution and the mixed monomer were added at a uniform rate over 12 minutes and stirred for 4 hours to obtain a polyacrylate emulsion.

The remaining steps were the same as in Example 2.

[0041] Test Example 1:

[0042] Antibacterial testing:

[0043] Test method: Tested in accordance with GB / T31402-2015, using Staphylococcus aureus and Escherichia coli. Results are shown in Table 1.

[0044] Table 1

[0045]

[0046]

[0047] From the comparison of the experimental data in Table 1, it can be found that the corrosion-resistant glass prepared in the present invention has good antibacterial ability.

[0048] From the comparison of the experimental data of Examples 1, 2, and 3 and Comparative Example 1 in Table 1, it can be found that the antibacterial rates of Examples 1, 2, and 3 are high. The difference between Comparative Example 1 and the Examples is that no tertiary amine group is introduced on the glass surface by forming a triazine ring, and it is impossible to react with the bromine group on the polyacrylate emulsion to form a quaternary ammonium salt. The quaternary ammonium salt has a positive charge and can be firmly adsorbed on the negatively charged bacterial cell surface by electrostatic attraction. After adsorbing on the bacterial surface, the quaternary ammonium salt inserts the hydrophobic group into the lipid layer, changes the permeability of the cell membrane, destroys the membrane structure, and causes leakage of intracellular substances; it can also interfere with the proton pump protein on the bacterial cell membrane, causing it to degrade or denature, affecting the material transport and energy metabolism of the cell, and ultimately causing the death of the bacteria, thereby achieving an antibacterial effect.

[0049] Test Example 2:

[0050] Corrosion resistance and durability testing:

[0051] Durability test: UV aging test was conducted. The glass prepared in each embodiment and comparative example was irradiated under a fluorescent UV lamp UV-A340 for 15 days to observe whether the glass turned yellow.

[0052] Corrosion resistance test: A salt bath test was conducted. Glass prepared in each example and comparative example was cut into 50 mm long and 20 mm wide strips in a constant temperature water bath. The strips were immersed in a 10% sodium chloride aqueous solution at 50°C for 8 hours, and the mass loss was measured. The results are shown in Table 2.

[0053] Table 2

[0054]

[0055]

[0056] From the comparison of the experimental data in Table 2, it can be found that the corrosion-resistant glass prepared by the present invention has good durability and corrosion resistance.

[0057] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 1 in Table 2, it can be found that Examples 1, 2, and 3 do not turn yellow. The difference between Comparative Example 1 and the Example is that no triazine ring is formed on the glass surface and no stable six-membered ring is formed through hydrogen bonding. Triazine can absorb ultraviolet light, convert light into heat energy and release it, thereby achieving an aging-resistant effect. In addition, the triazine formed by 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and 4-dimethylaminobenzonitrile, the hydroxyl group on 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile can form a stable conjugated six-membered ring with triazine through hydrogen bonding, which also has the effect of absorbing ultraviolet light and works together with the triazine structure to enhance the aging resistance of the material.

[0058] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 4, it can be found that the mass loss of Examples 1, 2, and 3 is small. The difference between Comparative Example 4 and the Examples is that 1-allyl-4-(trifluoromethyl)benzene monomer is not introduced into the polyacrylate emulsion. The electronegativity of fluorine atoms is extremely strong, and a tightly arranged fluorine atom layer can be formed to provide chemical inertness protection. In addition, the strong adsorption effect and small atomic radius of fluorine atoms enable fluorine atoms to be tightly arranged around carbon atoms, forming a protective barrier, thereby improving the corrosion resistance of the material.

[0064]

[0065] From the comparison of the experimental data in Table 3, it can be found that the corrosion-resistant glass prepared in the present invention has good antistatic ability.

[0066] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 1 in Table 3, it can be found that the surface resistivity of Examples 1, 2, and 3 is low. The difference between Comparative Example 1 and the embodiment is that no quaternary ammonium salt is formed on the glass surface. The quaternary ammonium salt cation can form a conductive layer on the material surface, increase the mobility of the charge on the material surface, thereby reducing the surface resistance, so that the static charge can be dissipated more quickly, and can also react with the negative charge on the material surface to neutralize, reduce the surface charge density, balance the charge distribution on the material surface, and achieve an antistatic effect.

[0067] From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 2, it can be found that the surface resistivity of Examples 1, 2, and 3 is low. The difference between Comparative Example 2 and the Example is that no polythiophene is formed on the glass surface. Polythiophene is a polymer compound with good electrical conductivity. Polythiophene can effectively conduct static charge, avoid the accumulation of static electricity, and achieve an antistatic effect.

[0068] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
