Problems solved by technology

In this method, both the real stone paint product and the standard sample obtained by toning during production are stirred, and air bubbles may be introduced into the standard sample during stirring, so that the color difference cannot be accurately measured and adjusted; and both have air bubbles after stirring However, the amount of air bubbles cannot be measured, and the problem of color difference cannot be fundamentally solved

Embodiment 1

[0091] To adjust the color difference of real stone paint, follow the steps below:

[0092] (a) When toning, take real stone paint and use a 100ml density cup to test its density; when the density obtained by the test is ≥ 1.68g / ml, directly scratch the color of real stone paint;

[0093] (b) In step (a), when the density obtained by the test<1.68g / ml, when the stirring speed is 400 revolutions per minute, the added amount of mineral oil defoamer is 1% of the quality of the real stone paint Add mineral oil defoamer to the real stone paint at 0.1%, take a sample after stirring for 10 minutes, and test its density;

[0094] If the density is less than 1.68g / ml, repeat the steps of adding mineral oil defoamer and measuring the density of real stone paint after adding mineral oil defoamer; until the measured density of real stone paint is ≥1.68g / ml , it is judged by scratch card color;

[0095] Among them, the mineral oil defoamer is Fermat MO NXZ AC (formerly known as Fermat NX...

Embodiment 2

[0097] The method for adjusting the chromatic aberration of real stone paint, except that the following content is different from Example 1, all the others are the same:

[0098] The density cup with fixed volume is 200ml density cup;

[0099] The stirring speed is 300 rpm, and the stirring time is 8 minutes;

[0100] The additional amount of mineral oil defoamer is 0.05% of the quality of the real stone paint;

[0101] Mineral oil defoamer is AF-309, San Nopco (Shanghai) Co., Ltd.

Embodiment 3

[0103] The method for adjusting the chromatic aberration of real stone paint is the same except that the following content is different from Example 1:

[0104] The density cup with fixed volume is 400ml density cup;

[0105] The stirring speed is 500 rpm, and the stirring time is 12 minutes;

[0106] The additional amount of mineral oil defoamer is 0.2% of the quality of the real stone paint;

[0107] Mineral oil defoamer is SN-DEFOAMER 154, San Nopco (Shanghai) Co., Ltd.

Abstract

The invention provides a method for adjusting the color difference of the real stone paint. The method includes the step of performing a density test on the real stone paint. When the density of the real stone paint obtained by the test is ≥1.68g / ml, the batch of real stone paint directly enters the toning step; when the density of the real stone paint obtained by the test is <1.68g / ml, add the The defoamer to eliminate bubbles is used until the final measured density of the real stone paint is ≥ 1.68g / ml, and then enters the coloring step. The method for adjusting the color difference of the real stone paint of the present invention can effectively adjust the color difference of the real stone paint, ensure the stability of the color of the real stone paint, and at the same time, it can conveniently and quickly judge the existing state of the bubbles in the production and coloring process of the real stone paint, and can effectively eliminate the color difference of the real stone paint. Air bubbles can directly and accurately judge the state of real stone paint; and on the basis of eliminating air bubbles, the color can be directly scratched to judge the color, the method is simple and easy to operate, and the color judgment is accurate.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a method for adjusting the color difference of real stone paint. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of water-based emulsion and natural stone powder of various colors. It has natural and real natural color and is suitable for indoor and outdoor decoration of various buildings. It is vivid and lifelike, and has a return to nature effect. At the same time, real stone paint has the characteristics of natural stone-like effect, wide application, water-based environmental protection, good weather resistance, long service life, and economic benefits, making it a popular product in the decorative paint market. The color and luster of real stone paint natural stone is an important factor that is loved by people, so the stability of color is an important aspect to measure the performance of re...
