[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...
