The remaining steps are the same as those of Example 2.

[0041] Test Example 1:

[0042] Antibacterial test:

[0043] Test method: tested according to GB / T31402-2015, and the selected bacteria were Staphylococcus aureus and Escherichia coli. The results are shown in Table 1.

[0044] Table 1

[0045]

[0046]

[0047] It can be found from the experimental data in Table 1 that the corrosion-resistant glass prepared by the present application has good antibacterial ability.

[0048] From the experimental data comparison of Example 1, 2, 3 and Comparative Example 1 in Table 1, it can be found that the bacteriostatic rates of Example 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 surface of the glass by forming a triazine ring, and no quaternary ammonium salt is generated by reacting with the bromine group on the polyacrylate emulsion. The quaternary ammonium salt has a positive charge, can be firmly adsorbed on the surface of the negatively charged bacterial cell by electrostatic attraction, and after being adsorbed on the surface of the bacterial cell, 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 the leakage of intracellular substances; it can also interfere with the proton pump protein on the bacterial cell membrane, cause its degradation or denaturation, affect the material transport and energy metabolism of the cell, and ultimately cause the death of the bacterial cell, thereby achieving the antibacterial effect.

[0049] Test Example 2:

[0050] Corrosion resistance and durability test:

[0051] Durability test: UV aging experiment was carried out, and the glasses prepared in each example and comparative example were irradiated under a fluorescent UV lamp UV-A340 for 15 days to observe whether the glasses were yellowed;

[0052] Corrosion resistance test: salt bath test was carried out, and the glasses prepared in each example and comparative example were immersed in a 10% sodium chloride aqueous solution in a constant temperature water bath, and the mass loss was tested after being placed at 50°C for 8h. The results are shown in Table 2.

[0053] Table 2

[0054]

[0055]

[0056] From the experimental data comparison of Example 1, 2, 3 and Comparative Example 1 in Table 2, it can be found that the corrosion-resistant glass prepared by the present application has good durability and corrosion resistance.

[0057] From the experimental data comparison of Example 1, 2, 3 and Comparative Example 1 in Table 2, it can be found that Example 1, 2 and 3 are not yellowed. The difference between Comparative Example 1 and the examples is that no triazine ring is formed on the surface of the glass, and no stable six-membered ring is formed by hydrogen bonding. The triazine can absorb ultraviolet light, convert the light into heat energy and release it, thereby achieving the effect of resisting aging. In addition, the triazine formed by 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile and 4-dimethylaminobenzonitrile has the effect of absorbing ultraviolet light, and the hydroxyl group on 4-hydroxythieno[2,3-B]pyridine-5-carbonitrile can form a stable conjugated six-membered ring with the triazine by hydrogen bonding, thereby enhancing the anti-aging ability of the material;

[0058] From the experimental data comparison of example 1, 2, 3 and comparative example 4, it can be found that the quality loss of example 1, 2, 3 is small, and the difference between comparative example 4 and example is that 1-allyl-4-(trifluoromethyl) benzene monomer is not introduced into the polyacrylate emulsion. The electronegativity of fluorine atom is very strong, which can form a layer of fluorine atom arranged closely to provide chemical inert protection. The strong adsorption effect and small atomic radius of fluorine atom enable fluorine atom to arrange closely around carbon atom to form a protective barrier and improve the corrosion resistance of the material.

[0059] Test example 3:

[0060] Antistatic test:

[0061] Test method: test the surface resistivity at 20℃. The results are shown in table 3.

[0062] Table 3

[0063]

[0064]

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

[0066] From the experimental data comparison of example 1, 2, 3 and comparative example 1 in table 3, it can be found that the surface resistivity of example 1, 2, 3 is low. The difference between comparative example 1 and example is that quaternary ammonium salt is not formed on the surface of the glass. Quaternary ammonium salt cation can form a conductive layer on the surface of the material, increase the mobility of electric charge on the surface of the material, thereby reduce the surface resistance, so that the static charge can dissipate faster. It can also neutralize the negative charge on the surface of the material, reduce the charge density on the surface of the material, balance the charge distribution on the surface of the material, and achieve the antistatic effect.

[0067] From the experimental data comparison of example 1, 2, 3 and comparative example 2, it can be found that the surface resistivity of example 1, 2, 3 is low. The difference between comparative example 2 and example is that polythiophene is not formed on the surface of the glass. Polythiophene is a kind of high molecular compound with good conductivity. Polythiophene can effectively lead out static charge to avoid the accumulation of static electricity and achieve the antistatic effect.

[0068] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
