Embodiment

[0027] The embodiments of the present invention provide inorganic interior wall paints and preparation methods thereof, and the mass percentages of raw materials in each embodiment are shown in Table 1.

[0028] Table 1 raw material mass percent (wt%)

[0029]

[0030]

[0031] Among them, the defoamer is Hemings Dechem 7010, the pH regulator is Dow AMP-9 (AMP-95), the titanium dioxide is Dupont R706, the polymer emulsion is Dow ELASTENE 2468, and the silica sol is Jiangsu Guolian Silica sol 1306, the thickener is Dow TT-935. The inorganic film former is a mixture of potassium silicate and silica sol.

[0032] The preparation method of above-mentioned inorganic interior wall coating comprises the following steps:

[0033] ① Add the hydroxyethyl cellulose to the deionized water at a stirring rate of 300-400r / min;

[0034] ② Disperse for 20 to 30 minutes at a stirring rate of 800 to 1200 r / min;

[0035] ③ Add the first part of defoamer, pH regulator, dispersant and wet...

Abstract

The invention relates to the field of water-based coating, in particular to inorganic interior wall coating and a preparation method thereof. The inorganic interior wall coating comprises the following components: deionized water, hydroxyethyl cellulose, a defoaming agent, a pH regulator, a wetting agent, a dispersing agent, a pigment filler, a high-molecular polymer emulsion, an inorganic film forming matter and a thickening agent. The inorganic film forming matter is a mixture of potassium silicate and silica sol. The inorganic interior wall coating adopts the raw materials and limits the weight percentage of each raw material so that the inorganic interior wall coating has good adhesive force, low-temperature stability and excellent flame resistance after film formation and is suitablefor interior wall coating or spraying.

Description

technical field [0001] The invention relates to the field of interior wall coatings, in particular to an inorganic interior wall coating and a preparation method thereof. Background technique [0002] Inorganic interior wall paint is a kind of paint commonly used in construction projects at present. For example, in the current subway construction projects, the paint used in rail transit tunnels is mainly inorganic interior wall paint. Due to the requirements of the use environment, it is necessary not only to meet HJ2537-2014 "Technical Requirements for Environmental Labeling Products Waterborne Coatings", GB / T 9756-2018 "Synthetic Resin Emulsion Interior Wall Coatings", GB8624-2012 "Classification of Combustion Performance of Building Materials and Products ", JC / T 423-1991 "Water-Soluble Interior Wall Paint" standard requirements, with good adhesion, mildew resistance and excellent flame resistance, it should also have good appearance and low temperature stability. Howev...
