Embodiment 1

[0038] First add 150 parts of deionized water to the beaker, add 1 part of EK 50 and 1 part of silver nitrate at a speed of 300 rpm, and continue stirring for 5 minutes; add 15 parts of lithium silicate at a speed of 400 rpm , continue stirring for 10 minutes; increase the speed to 500 rpm, add 15 parts of potassium silicate, and continue stirring for 10 minutes; add 1 part of TEGO 2000; add 1 part of silicone defoamer, 1 part of poly Methylsiloxane leveling agent, continue to stir for 10 minutes, and finally get super wear-resistant long-lasting antibacterial and antiviral nano-coating.

[0039] The paint is used as follows:

[0040] (1) Stir well before use, filter with a 400-mesh filter, and apply air precision spraying on glass sheets or stainless steel sheets with a coating thickness of 50 microns;

[0041] (2) Bake at 50°C for 10 minutes and at 180°C for 30 minutes.

Embodiment 2

[0043] First add 200 parts of deionized water to the beaker, add 3 parts of EK 50 and 3 parts of silver nitrate at a speed of 300 rpm, and continue stirring for 5 minutes; add 20 parts of silicic acid at a speed of 400 rpm Lithium, continue to stir for 10 minutes; increase the speed to 500 rpm, add 35 parts of potassium silicate, continue to stir for 10 minutes; add 1.5 parts of TEGO 2000; add 2 parts of polyether modified silicone foaming agent, 2 parts of organically modified polydimethylsiloxane leveling agent, continue to stir for 10 minutes, and finally get a super wear-resistant long-lasting antibacterial and antiviral nano-coating.

[0044] The using method of coating is identical with embodiment 1.

Embodiment 3

[0046] First add 250 parts of deionized water to the beaker, add 3 parts of EK 50 and 2 parts of silver nitrate at a speed of 300 rpm, and continue stirring for 5 minutes; add 20 parts of lithium silicate at a speed of 400 rpm , continue to stir for 10 minutes; increase the speed to 500 rpm, add 30 parts of potassium silicate, and continue to stir for 10 minutes; add 2 parts of TEGO 2000; add 2 parts of silicone defoamer, 2 parts of poly Methylsiloxane leveling agent, continue to stir for 10 minutes, and finally get super wear-resistant long-lasting antibacterial and antiviral nano-coating.

[0047] The using method of coating is identical with embodiment 1.

Abstract

Provided is a super-wear-resistant long-acting antibacterial and antiviral nano-coating comprising the components in parts by weight: 30 to 75 parts of composite silicate, 2 to 6 parts of an antibacterial agent, 1 to 3 parts of an antiviral agent, 1 to 3 parts of a defoamer, 1 to 3 parts of a leveling agent and 150 to 350 parts of deionized water. Silver ions can be slowly and controllably released from the interior of the coating layer continuously, so that rapid and long-term antibacterial ability is obtained; a pure inorganic component coating layer is formed through a Sol-Gel reaction of lithium silicate and potassium silicate, and the coating layer is non-toxic and harmless, has ultrahigh hardness and wear resistance, and also has the characteristics of easiness in cleaning and fingerprint resistance; the preparation method is simple and good in repeatability, and industrial large-scale production is easy to realize.

Description

technical field [0001] The patent of the invention relates to the technical field of chemical industry, in particular to a super wear-resistant long-acting antibacterial and antiviral nano-coating and its preparation method. Background technique [0002] In public places, various electronic equipment touch screens, elevator buttons, door handles, subway bus handrails, and kindergarten toys are in high-frequency contact with each other, which greatly increases the risk of bacteria and virus transmission. Especially in the face of highly cross-infectious viruses such as the new coronavirus, the only way is to physically isolate or frequently use disinfectant through facial tissue, which not only brings huge waste of resources, but also easily causes omissions and hidden dangers of transmission. [0003] Most of the coatings formed by antibacterial and antiviral coatings on the market contain antibacterial or antiviral components on the surface. Once the coating is worn, it wil...
