Problems solved by technology

[0005] Usually, the method of making the paint have antibacterial function is to achieve the purpose of making the paint film antibacterial by adding organic heterocyclic fungicides and inorganic oxide antibacterial agents. The shortcomings of the two are also very obvious: organic fungicides themselves Highly harmful, 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 effect of both is very poor

preparation example Construction

[0114] The preparation method of the high-adhesion long-acting antibacterial and low-volatility interior wall paint of the present invention comprises the steps:

[0115] The various components of the high-adhesion long-acting antibacterial and low-volatility interior wall paint composition of the present invention are mixed to obtain the high-adhesion long-acting antibacterial and low-volatility interior wall paint.

[0116] In a specific embodiment, the long-acting antibacterial ultra-low volatility interior wall paint is prepared by a method comprising the following steps:

[0117] a) Put the pure water into the dispersing tank, and control the speed at 700-800 rpm;

[0118] b) Slowly add the dispersant, wetting agent, defoamer, and thickener into the dispersion tank in turn for 15 minutes;

[0119] c) Then add various pigments and fillers in turn;

[0120] d) Then add the pH regulator and stir for 1 minute;

[0121] e) Then control the rotation speed at 1400-1500 rpm, a...

Abstract

The invention provides a high-adhesive-force inner wall coating composition which mainly comprises the following components in part by weight: 35.0-40.0 parts of film-forming substance, 0.4-0.6 part of freeze-thawing stabilizer, 35.0-40.0 parts of pigment filler, 5-7 parts of coating auxiliary agent, 0-0.2 part of adhesive force promoter and acceptable amount of water, wherein the film-forming substance is aqueous mixed emulsion of high-molecular-weight and low-molecular-weight epoxy resin, and the high-molecular-weight and / or low-molecular-weight epoxy resin contain / contains 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 synthetic resin antibacterial coating characterized by high adhesion, high environmental protection and high performance and a preparation method thereof, more specifically relates to a high adhesion long-acting antibacterial low Volatile paint and method for its 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. In addition to the large-scale overall decoration of new houses, the continuous improvement and repair of existing decorations during the living process is also an important part of interior decoration. important part. In addition, compared with the simple decoration that was mainly clean and practical in the past, now there are more requirements for decoration, such as beauty, decoration, and personal style and preferences. The interior wall of the living room plays a basic role ...
