preparation example Construction

[0032] A preparation method of low-consumption real stone paint, the concrete steps are as follows:

[0033] (1) Put some water into the dispersion tank, adjust to 500-700 rpm, then add hydroxyethyl cellulose, and disperse for 3-5 minutes;

[0034] (2) Then adjust the rotating speed to 700-1000 rpm, add multifunctional additives, and disperse for 3-5 minutes;

[0035] (3) Then keep the rotation speed at 700-1000 rpm, then put in pure acrylate emulsion, disperse for 3-5 minutes, adjust the rotation speed to 500-700 rpm, then add bactericidal preservatives, freeze-thaw stabilizers, synthetic Membrane aid and alkali swelling thickener, continue to disperse for 3-5 minutes;

[0036] (4) Continue to maintain 500-700 rpm, put in 0.2-4.0 parts of PH regulator, 10.0-40.0 parts of silica sol, 20.0-90.0 parts of styrene-acrylic emulsion, 40-60 parts of slip agent, 1-2 parts of antifreeze , 1-2 parts of water-based defoamer, and then continue to disperse for 3-5 minutes.

[0037] (5) ...

Embodiment 1

[0039] In order to achieve a good spraying atomization effect, stable storage performance and excellent temperature-varying color difference performance, in this embodiment 1, a variety of hydroxyethyl cellulose and a variety of acrylate emulsions in the low-consumption real stone paint formula are selected to be orthogonally matched The screened schemes are respectively numbered "Formulation 1", "Formulation 2" ... "Formulation 9", prepared according to the components and mass / number ratios shown in Table 1:

[0041]

[0042]

[0043] The preparation method of the low consumption real stone paint of this implementation is according to the following steps:

[0044] (1) Put water into the dispersion tank, adjust to 500 rpm, then add hydroxyethyl cellulose, and disperse for 5 minutes;

[0045] (2) Then adjust the rotation speed to 700 rpm, add multifunctional addit...

Embodiment 2

[0056] In order to further optimize the storage performance of the formula, in Example 2, the cellulose in the low-consumption real stone paint formula was selected for gradient comparison testing, respectively numbered "Formula 10" to "Formula 13", and the components shown in Table 3 Formulated with the ratio of parts by mass:

[0057] Table 3 Different Gradient Formulas Containing Cellulose

[0058]

Abstract

The invention relates to a low-consumption stone-like coating and a preparation method thereof. The stone-like coating is prepared from the following raw materials in parts by mass: 100-120 parts of water, 1-3 parts of hydroxyethyl cellulose, 0.3-0.5 parts of a multi-functional additive, 120-140 parts of acrylate emulsion, 1-2 parts of a bactericidal preservative, 3.5-4.5 parts of a freeze-thaw resistant stabilizer, 3-4 parts of a coalescing agent, 0.2-0.5 parts of an alkali swelling thickene, 300-600 parts of sand, 100-300 parts of color sheets, 0.2-4.0 parts of a pH regulator, 10.0-40.0 parts of silica sol, 20.0-90.0 parts of styrene-acrylic emulsion, 40-60 parts of a slipping agent, 1-2 parts of an anti-freezing agent and 1-2 parts of a water-based defoaming agent. According to the invention, proper cellulose is screened out from different celluloses and is reasonably matched with the emulsion, so that the stability and constructability of a product are improved, and the water retention property and thixotropic property of the system are improved; the acrylic ester emulsion is selected, so that the problem that a stone-like coating using common styrene-acrylic emulsion is easy to yellow is effectively solved; and the problem that color difference between batches is difficult to control can be effectively solved through application of the color sheets.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a low-consumption real stone paint and a preparation method thereof. Background technique [0002] Due to the pressure of environmental protection policies, the mining of natural colored sand will be stopped at any time, followed by the risk that the supply of real stone lacquer colored sand cannot be guaranteed. Coupled with the current increase in labor costs year by year, the profits of the construction party and the general contractor have been greatly reduced. Therefore, the development of a low-consumption real stone paint can greatly improve the construction efficiency of workers, save construction costs, increase the profits of the construction party and the general contractor, and reduce the construction load; secondly, it can reduce or not add natural colored sand. Reduce environmental damage caused by colored sand mining. Contents of the invention [0003] The invention pro...
