[0059] The invention provides a method for preparing a paint with a bactericidal function, which comprises the following steps in sequence: adding Korean pine essential oil, tea polyphenols and a solvent to the film-forming substance at a speed of 400 to 800 rpm, and then adjusting the speed Disperse at 600-800 rpm for 10-15 minutes to obtain a coating.
[0060] The present invention provides another preparation method of a paint with bactericidal function, which comprises the following steps carried out in sequence:
[0061] S1 Mixing for the first time: add a dispersant and an antifoaming agent to the film-forming material, disperse at a speed of 600-800 rpm for 5-8 minutes and mix evenly to obtain the first mixed material;
[0062] S2 The second mixing: Add the first mixed material at the speed of 600-800 rpm, add the Silamaya powder and the color-changing powder, adjust the speed to 800-1000 rpm and disperse for 10-15 minutes until the fineness < 55 μm to obtain the secon...
