Problems solved by technology

Usually by adding organic heterocyclic fungicides and inorganic oxide antibacterial agents to achieve the antibacterial function, the shortcomings of both are also very obvious: organic fungicides themselves are highly biohazardous, and inorganic oxides The antibacterial effect of antibacterial agents is poor, and the long-term effect of both is very poor

preparation example Construction

[0104] The preparation method of the long-acting antibacterial and water-resistant environmental protection interior wall putty of the present invention comprises the following steps:

[0105] The various components of the composition described in claim 1 are mixed to obtain the long-acting antibacterial and water-resistant environmental protection interior wall putty.

[0106] In a specific embodiment, the long-acting antibacterial and water-resistant environmental protection interior wall putty is made by the method comprising the following steps:

[0107] a) Put the pure water and the thickener into the dispersion tank, and control the rotation speed at 1700-1800 rpm to obtain a uniform dispersion;

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

[0109] c) then add the pH regulator and stir for 1 minute;

[0110] d) Then control the rotation speed at 1400-1500 rpm, and disperse for 20 minutes;

[0111] ...

Abstract

The invention provides a long-acting antibacterial water-resistant environment-friendly inner wall putty composition which mainly comprises the following components in part by weight: 15.0-20.0 parts of emulsion, 0.4-0.6 part of freeze-thawing stabilizer, 35.0-40.0 parts of filler, 2-5 parts of auxiliary agent, 1.0-1.5 parts of anion antibacterial additive and acceptable amount of water, wherein the emulsion is acrylic acid copolymer emulsion containing a functional group capable of stably complexing with silver ion; the freeze-thawing stabilizer is long-chain epoxyethane (EO) block fatty alcohol polyoxyethylene ether; and based on the total weight of the composition, the total content of volatile organic compounds (VOC) in the composition is not higher than 0.01wt%.

Description

technical field [0001] The invention relates to a water-resistant interior wall putty characterized by high environmental protection and high performance and a preparation method thereof, more specifically relates to a long-acting antibacterial, water-resistant and environment-friendly interior wall putty with acrylic resin as the main film-forming substance and its Preparation. Background technique [0002] With the continuous improvement of people's living standards and quality of life, people pay more and more attention to the layout and style of the living room, and the interior wall of the living room plays a fundamental role in the entire decoration process, especially the promotion and application of paint and paint. , making the color and texture of the wall more and more colorful. However, when the wall is painted with these decorative materials, the interior wall putty must be used to smooth the surface of the wall. In addition, putty also plays an important role...
