Problems solved by technology

[0007] Usually, the method of making the coating have antibacterial function is to achieve the antibacterial effect of the paint film by adding organic heterocyclic fungicides and inorganic oxide antibacterial agents. The disadvantages of the two are also very obvious: the biohazardous nature of organic fungicides themselves High, the antibacterial effect of inorganic antibacterial agents is poor, it is easy to damage the paint film, affecting the lasting brightness of the paint film, and the long-term performance of both is very poor
[0008] In summary, this area lacks a long-acting antibacterial ultra-low volatility interior wall coating composition, and maintains good conventional application performance

preparation example Construction

[0104] The preparation method of long-acting antibacterial ultra-low volatility interior wall paint of the present invention comprises the steps:

[0105] The various components of the composition described in claim 1 are mixed to obtain the long-acting antibacterial ultra-low volatility interior wall paint.

[0106] In a specific embodiment, the long-acting antibacterial ultra-low volatility interior wall paint is prepared by a method comprising the following steps:

[0107] a) Put the pure water into the dispersing tank, and the rotating speed is controlled at 700-800 rpm;

[0108] b) Slowly add the dispersant, wetting agent, defoamer, and thickener into the dispersion tank in turn for 15 minutes;

[0109] c) Then add various pigments and fillers in turn;

[0110] d) Then add the pH regulator and stir for 1 minute;

[0111] e) Then the rotating speed is controlled at 1400-1500 rpm, and dispersed for 20 minutes;

[0112] f) then add a small amount of pure water to cool do...

specific Embodiment approach

[0129] The present invention is further illustrated below by examples and comparative examples.

[0130] In the following implementation and comparative examples, the long-acting antibacterial ZERO-VOC advanced interior wall coatings were investigated for their freeze-thaw stability, film-forming properties, and antibacterial properties.
