Problems solved by technology

[0006] 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

preparation example Construction

[0107] The preparation method of the long-acting antibacterial, stain-resistant and water-resistant interior wall paint of the present invention comprises the following steps:

[0108] The various components of the composition described in claim 1 are mixed to obtain the long-acting antibacterial, stain-resistant, and water-resistant interior wall paint.

[0109] In a specific embodiment, the long-acting antibacterial, stain-resistant, and water-resistant interior wall paint is prepared by a method comprising the following steps:

[0110] a) Put the pure water into the dispersing tank, and control the speed at 700-800 rpm;

[0111] b) Slowly add the dispersant, wetting agent, defoamer, and thickener into the dispersion tank in turn for 15 minutes;

[0112] c) Then add various pigments and fillers in turn;

[0113] d) Then add the pH regulator and stir for 1 minute;

[0114] e) Then control the rotation speed at 1400-1500 rpm, and disperse for 20 minutes;

[0115] f) then a...

Abstract

The invention provides a long-acting antibacterial anti-contamination waterproof interior wall coating composition. The composition mainly consists of the following components in parts by weight: 35.0-40.0 parts of film forming material, 0.4-0.6 part of freeze thawing stabilizer, 35.0-40.0 parts of pigment filler, 5.0-7.0 parts of coating additive, 2.0-5.0 parts of nano filler and acceptable amount of water, wherein the film forming material is water-based fluorocarbon resin emulsion containing a functional group capable of stabilizing complex silver ions; the freeze thawing stabilizer is long-chain ethylene oxide (EO) block fatty alcohol-polyoxyethylene ether; and the total content of VOC (volatile organic compounds) in the composition is not greater than 0.01wt% based on the total weight of the composition.

Description

technical field [0001] The invention relates to a synthetic resin antibacterial coating characterized by high environmental protection and high performance and a preparation method thereof, more specifically to a long-acting antibacterial, stain-resistant, and water-resistant coating composed of water-based fluorocarbon resin as the main film-forming substance and its preparation method. Preparation. Background technique [0002] With the continuous improvement of people's living standards and quality of life, people carry out interior decoration more and more frequently, and compared with the simple decoration that was mainly clean and practical in the past, the interior decoration now has more beauty, decoration, and personal style. More requirements such as preferences. The interior wall of the living room plays a basic role in the whole decoration link, so the interior wall coating as the main tool for interior wall decoration has also become an important building decor...
