Embodiment 1

[0026] A kind of real stone paint, its composition and mass percentage are:

[0027]

[0028]

[0029] A method for preparing the above-mentioned real stone paint, comprising the following steps:

[0030] (a) Put water into a clean paint vat, start the disperser and stir at 500RPM;

[0031] (b) Put lauryl alcohol ester and mineral oil in sequence, and disperse for 3 minutes at 500RPM;

[0032] (c) Add hydroxyethyl cellulose and disperse at 500RPM for 3 minutes;

[0033] (d) When the hydroxyethyl cellulose is completely wetted and stirred evenly, adjust the pH to 8.5, and increase the speed to above 1000RPM to disperse for 3 minutes when the viscosity increases;

[0034] (e), put in water-based acrylate emulsion, and stir at 500RPM for 10 minutes;

[0035] (f) After stirring evenly, add Kathon LEX and stir at 500RPM for 3 minutes;

[0036] (g) Adjust the viscosity to 40000cps / 25°C after mixing the above prepared ingredients with quartz sand.

Embodiment 2

[0038] A kind of real stone paint, its composition and mass percentage are:

[0039]

[0040] A method for preparing the above-mentioned real stone paint, comprising the following steps:

[0041] (a) Put water into a clean paint vat, start the disperser and stir at 500RPM;

Abstract

The invention relates to paint and a preparation method thereof, and specially relates to stone-like paint and a preparation method thereof. The stone-like paint mainly comprises an emulsion, cellulose ether and aggregate. The stone-like paint provided by the invention is good in film forming ability, does not crack, and has the prominent advantage that the stone-like paint is dried in a short period (2 h) during construction under the condition of low temperature (5-7 DEG C) and high humidity (70-80%) and is not whitened when meeting water; and the stone-like paint provided by the invention has excellent contamination resistance, excellent water whitening resistance and good in color retention and endurance, and is capable of overcoming rain print phenomenon.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a real stone paint and a preparation method thereof. Background technique [0002] At present, there are many kinds of decorative coatings. The imitation granite real stone paint is rich in the connotation of natural granite, which shows the noble grade of granite. It is a new upgraded variety of traditional natural real stone paint. Real stone paint has strong decoration, wide application and good durability. , Not easy to fade and other characteristics, so it is a kind of popular exterior wall decoration paint. In the construction and application of real stone paint, some problems that affect the quality and decorative effect often appear, such as the coating is too soft, the coating turns white when it meets water, and there is too much sand falling off during spraying, etc., which have certain universality. When using real stone paint, it is difficult to construc...
