Problems solved by technology

At present, chlorine dioxide is less used as an antibacterial and antiviral agent in the ceramic tile industry, because when chlorine dioxide is used alone, its antibacterial and antiviral time is relatively short, and it is not suitable for ceramic tiles that have been used for several years or even decades. industry, and when the concentration of chlorine dioxide in the air is greater than 10%, it is easy to explode and has certain dangers
[0005] At present, there are still no ceramic tile products on the market that can purify formaldehyde, antibacterial, anti-virus, and are suitable for night and dark rooms.

preparation example Construction

[0053] A preparation method of an antibacterial and antiviral formaldehyde-removing antifouling agent, which is used to prepare the above-mentioned antibacterial and antiviral formaldehyde-removing antifouling agent, comprising the following steps:

[0054] (1) Mix the modified hematilite, the stable chlorine dioxide solution and the silver diammine hydroxide solution evenly according to the formula ratio, and then dry them to obtain the modified hematilite immobilized silver chloride fine powder;

[0055] (2) Mix the modified hematilite-supported silver chloride fine powder, hydroxyl-terminated dimethylsiloxane, water-based aliphatic polyurethane and dispersant according to the formula ratio to obtain an antibacterial, antiviral, formaldehyde-removing and antifouling agent.

[0056] In one embodiment of the present invention, the specific step of step (1) is to mix the modified hematilite, the stable chlorine dioxide solution and the silver diammine hydroxide solution accordin...

Embodiment 1-5

[0072] An antibacterial, antiviral, formaldehyde-removing and antifouling agent. The raw materials of the antifouling agent include 10-20 parts of modified staphilite immobilized silver chloride fine powder, 50-70 parts of hydroxyl-terminated dimethylsiloxane, 10-20 parts 20 parts of water-based aliphatic polyurethane and 1-2 parts of dispersant; wherein, the fineness of the modified staphilite immobilized silver chloride fine powder is 1000 mesh;

[0073] Wherein, the modified hematilite immobilized silver chloride fine powder is prepared from 10-30 parts of modified hematilite, 50-70 parts of stable chlorine dioxide solution and 5-20 parts of diammine silver hydroxide solution. Wherein, the modified hematilite is sulfuric acid modified hematilite.

[0074] Concrete, the raw material formula of antifouling agent among the embodiment 1~5 is as shown in following table 1:

[0075]

[0076] The preparation method of antibacterial antiviral formaldehyde antifouling agent in t...

Embodiment 6

[0087] The raw material formula ratio of antibacterial and antiviral formaldehyde-removing antifouling agent in embodiment 6 ~ 8 is identical with embodiment 2, and difference is, the glazed tile of embodiment 6 ~ 8 is non-glazed tile, and wherein embodiment 6 adopts spraying Antibacterial and antiviral formaldehyde-removing antifouling agent is coated on the surface of this non-glazed tile by the mode of antibacterial; Embodiment 7 adopts the mode of brushing and antibacterial antiviral formaldehyde-removing antifouling agent is coated on the surface of this non-glazed tile; Example 8 The method of immersion is to apply the antibacterial, antiviral, formaldehyde-removing and antifouling agent on the surface of the non-glazed tile.

[0088] Using the above method, antibacterial and antiviral formaldehyde-removing glazed tiles were prepared, and the obtained antibacterial and antiviral formaldehyde-removing glazed tiles were prepared according to JC / T 897-2014 "Antibacterial Per...

Abstract

The invention discloses an antibacterial and antiviral formaldehyde-removing antifouling agent and a preparation method thereof, and a glazed tile and a preparation method thereof, the antibacterial and antiviral formaldehyde-removing antifouling agent comprises the following raw materials by weight: 10-20 parts of modified stellerite immobilized silver chloride fine powder; the modified stellerite immobilized silver chloride fine powder is prepared from 10 to 30 parts of modified stellerite, 50 to 70 parts of a stable chlorine dioxide solution and 5 to 20 parts of a silver diamminohydroxide solution. According to the present invention, the modified stellerite, the stable chlorine dioxide solution and the silver silver diamminohydroxide solution are compounded, such that the anti-fouling agent can simultaneously have effects of antibacterial property, antiviral property and formaldehyde removing, and the effective sterilization time of the anti-fouling agent is significantly prolonged. The antibacterial, antiviral and formaldehyde-removing glazed tile is prepared from the antifouling agent, so that the glazed tile can play a powerful and lasting role in inhibiting bacteria, fungi and viruses, and can also achieve the effect of purifying formaldehyde.

Description

technical field [0001] The invention relates to the technical fields of antifouling agents and building ceramics, in particular to an antibacterial, antiviral, formaldehyde-removing antifouling agent and a preparation method thereof, glazed tiles and a preparation method thereof. Background technique [0002] With the development of economy and society, people pay more and more attention to the concept of health, and various healthy tiles have appeared in the tile industry, such as negative ion tiles, antibacterial tiles, etc. [0003] Negative ion tiles can purify formaldehyde, but negative ions have strong radiation, which is not conducive to health. The antibacterial tiles have antibacterial effect. Traditional antibacterial tiles are divided into two processes. One is to introduce metal elements with bactericidal function into the glaze, such as silver, zinc, copper, etc., which are made by sintering and polishing. Contact antibacterial tile products, but because the gl...
