Example Embodiment

[0029] The formula of the embodiment of the present invention is shown in Table 1:

[0030] Table 1: (Unit: weight percentage)

[0031]

[0032] According to the above formula, the preparation method is carried out as follows:

[0033] ①. Add deionized water, moisturizing antifreeze and additives into the mixer and disperse at a speed of 300-800r / min (300-800 revolutions per minute) for 15 minutes to obtain a uniform mixed solution;

[0034] ②. Add all the inorganic pigments to the uniform mixed solution obtained in step ①, and disperse at a speed of 2000-3000r / min (2000-3000 revolutions per minute) for 30 minutes or more, and slowly add the pH adjuster during the dispersion process , Obtain the pre-mixed inorganic pigment color paste;

[0035] ③. Grind the pre-mixed inorganic pigment paste obtained in step ②, and stop the grinding when the fineness is ≤ 20.0 μm to obtain the initial inorganic pigment paste;

[0036] ④. After quality inspection, vacuum deaeration and filtration and pack...

Abstract

The present invention discloses an inorganic pigment color paste and a preparing method thereof. The color paste consists of raw materials in the following percentages based on the total weight: 30.0 to 50.0% of inorganic pigment, 5.0 to 20.0% of moisture retaining and anti-freezing agent, 5.0 to 15.0% of auxiliary, 0.5 to 2.0% of pH regulator, 0.2 to 0.5% of antifoaming agent and the balance of deionized water. Neither the moisture retaining and anti-freezing agent nor the auxiliary contains volatile organic compounds (VOC). After all ingredients are mixed and ground, quality detection, vacuum defoaming, filtering and packaging are carried out, and the inorganic pigment color paste required is finally obtained. The inorganic pigment color paste prepared has the excellent moisture retaining properties and stability under the condition of reaching low content index of VOCs. The present invention also has the advantages of low cost, simple production processes and easy industrial production.

Description

technical field [0001] The invention relates to the field of water-based wall latex coloring, in particular to an inorganic pigment paste and a preparation method thereof. Background technique [0002] At present, the use of water-based color paste has been widely used in interior and exterior wall latex paint toning. Usually, a large amount of low-boiling alcohol ether organic solvents such as ethylene glycol and propylene glycol are added to the color paste to improve the moisturizing and antifreeze effect, so as to prolong its storage time and reduce the Its drying speed is convenient to use (generally, it is required to pass the 24-hour test at 25°C and 60% relative humidity). [0003] With the strengthening of people's awareness of environmental protection, the environmental requirements for latex paint are becoming more and more stringent: such as the national standard GB18582-2008 "Limits of Harmful Substances in Interior Decoration Materials and Interior Wall Coating...
