Problems solved by technology

The existing antibacterial coatings generally achieve the purpose of making the paint film antibacterial by adding organic heterocyclic bactericides and inorganic oxide antibacterial agents. The shortcomings of the two are also very obvious: organic bactericides are highly biohazardous, Inorganic antibacterial agents have poor antibacterial effect and are easy to damage the paint film, affecting the lasting brightness of the paint film, and the long-term performance of both is very poor
In addition, some paint products use silver ions to achieve the purpose of sterilization, but because the raw material price of silver ions is relatively high, the price of paint products is greatly increased.
The anti-radiation coating products realize the anti-radiation function by adding iron oxide, quartz powder, calcium carbonate and other traditional anti-radiation substrates, but there is no product that can meet these requirements at the same time.
[0006] In addition, as the requirements for the quality of life continue to increase, materials with functions such as releasing negative ions, adjusting air humidity, and purifying the air have a wider application market, and some materials with some of these functions have appeared one after another. Coating products, but they often have a single function, and it is difficult to meet multiple environmental protection needs at one time
In summary, the art lacks an interior wall paint composition with multiple environmental improvement functions, and maintains good conventional application performance

[0105] The preparation method of the interior wall paint with multiple environmental improvement functions of the present invention comprises the following steps:

[0106] The various components of the composition described in the first aspect above are mixed to obtain the interior wall paint with multiple environmental improvement functions.

[0107] In a specific embodiment, the interior wall paint with multiple environmental improvement functions is prepared by a method comprising the following steps:

[0108] a) Put the pure water into the dispersing tank, and control the speed at 700-800 rpm;

[0109] b) Slowly add the dispersant, wetting agent, defoamer, and thickener into the dispersion tank in turn for 15 minutes;

[0110] c) Then add various pigments and fillers in turn;

[0111] d) Then add the pH regulator and stir for 1 minute;

[0112] e) Then control the rotation speed at 1400-1500 rpm, and disperse for 20 minutes;

[0113] f) then add a small amount of pure ...
