preparation example Construction

[0042] Specifically, the preparation method of inorganic interior wall paint comprises the following steps: at a stirring speed of 400-500rpm, adding cellulose, dispersant, antifoaming agent and wetting agent to water, and adding filler after uniform dispersion, stirring at 800-1200rpm Disperse evenly under stirring at a high speed, and prepare the slurry;

[0043] Add silica sol, stabilizer and organosilicon water-repelling agent to the stock preparation slurry, disperse evenly at a stirring speed of 600-800 rpm, and then add a thickener to obtain the inorganic interior wall paint.

[0044] In order to verify the performance of the inorganic interior wall coating of the present invention, the present invention tested the inorganic interior wall coating according to JG / T 26-XXXX, see the experimental example below for details.

Embodiment 1

[0050] The present embodiment provides a kind of inorganic interior wall paint, and its preparation method is as follows:

[0051] At a stirring speed of 400rpm, add 4kg cellulose, 6kg dispersant, 2kg defoamer and 3kg wetting agent into the water in sequence, and continue stirring for 2 minutes after the addition is complete until the dispersion is uniform, then add 400kg of filler, and stir for 30 minutes at a stirring speed of 800rpm Until the dispersion is uniform, the slurry is prepared;

[0052] Add 350kg of silica sol, 5kg of stabilizer and 10kg of organosilicon hydrophobic agent to the stock preparation slurry in turn, after adding, stir at a stirring speed of 600rpm for 5min until uniformly dispersed, then add 2kg of thickener, and continue stirring until uniformly dispersed, to obtain The inorganic interior wall paint.

[0053] The viscosity of the above-mentioned inorganic interior wall paint measured by a Stormer viscometer at 25°C was 78KU.

Embodiment 2

[0055] The present embodiment provides a kind of inorganic interior wall paint, and its preparation method is as follows:

[0056] At a stirring speed of 500rpm, add 3kg cellulose, 5kg dispersant, 3kg defoamer and 1kg wetting agent into the water in sequence, and continue stirring for 2 minutes until the dispersion is uniform, then add 350kg filler, and stir at a stirring speed of 1000rpm for 30 minutes Until the dispersion is uniform, the slurry is prepared;

[0057] Add 300kg of silica sol, 3kg of stabilizer and 20kg of organosilicon hydrophobic agent to the stock preparation slurry in turn, after the addition is completed, stir at a stirring speed of 800rpm for 5min until uniformly dispersed, then add 2kg of thickener, and continue stirring until uniformly dispersed, to obtain The inorganic interior wall paint.

[0058] The viscosity of the above-mentioned inorganic interior wall paint measured by a Stormer viscometer at 25°C was 80KU.

Abstract

The invention discloses an inorganic interior wall coating and a preparation method thereof. The inorganic interior wall coating is prepared from the following raw materials: 150 to 200 parts of water, 300 to 400 parts of filler, 2 to 4 parts of cellulose, 5 to 8 parts of a dispersing agent, 1 to 3 parts of a wetting agent, 2 to 3 parts of a defoaming agent, 3 to 5 parts of a stabilizing agent, 300 to 400 parts of silica sol, 1 to 2 parts of a thickening agent and 10 to 20 parts of an organic silicon water repellent agent. According to the inorganic interior wall coating provided by the invention, all the raw materials are matched with one another, so that the inorganic interior wall coating not only has alkali resistance and mildew resistance, but also is not easy to crack in a coating and film forming process, and the fireproof grade can reach A1 grade.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an inorganic interior wall paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, consumers' requirements for quality of life have also been greatly improved, especially the problem of decoration pollution is becoming more and more important. Traditional oil-based paints use organic solvents as solvents, which not only easily release volatile organic compounds (VOC), pollute the atmosphere, but also pose a fire hazard during the construction process. In addition, when oil-based paint is used as interior wall paint, it will also release organic solvents into the room, directly endangering people's health. [0003] In response to the above problems, people have developed inorganic coatings. Inorganic coatings are coatings that use inorganic materials as the main film-forming substance. They are the abbreviation of ...
