Embodiment Construction

[0019] The formula of the embodiment of the invention is referring to Table 1:

[0020] Table 1: (unit: weight percentage)

[0021]

[0022] The titanium dioxide color paste prepared according to the above formula has high pigment content, appropriate viscosity, and good fluidity. After 3 years of storage, the various indicators of the color paste (coloring power, fineness, viscosity, compatibility) have no change, and there is no liquid separation. , no precipitation and other disadvantages; has excellent storage stability.

[0023] The preparation process of the present invention is:

[0024] When preparing water-oil universal titanium dioxide slurry, add wetting and dispersing agent, defoamer, and multiplier to the co-solvent, mix evenly, put in the corresponding amount of titanium dioxide toner, disperse at high speed for 45 minutes, and then grind for 2 hours. To achieve satisfactory fineness, slow dispersion and defoaming, filter and pack to get the required color p...

Abstract

The invention discloses a water and oil applicable titanium dioxide color paste, which is consisting of titanium dioxide pigment, wet dispersing agent, foam killer, multiplying agent and latent solvent, which are proportioned in gross weight percent as follows: 50.0-70.0 percent of titanium dioxide pigment, 8.0-15.0 percent of wet dispersing agent, 0.2-0.5 percent of foam killer, 1.0-2.0 percent of multiplying agent, and the rest percent of latent solvent. All components are mixed to perform quality testing, slow dispersing and killing foam and filtering package after high-speed dispersion and grinding, and finally the required water and oil applicable titanium dioxide color paste is obtained. The water and oil applicable titanium dioxide color paste according to the invention has the advantages of high pigment content, good fluidity, high tinting strength, excellent storage stability, low cost, powerful versatility, simple preparation process, suitability for industrial production, especially suitable for water or oil paint color system mixing.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-oil universal titanium dioxide color paste for water-based and oily coatings. Background technique [0002] A large number of color pastes have been used in system color matching, and the color pastes used include iron oxide, phthalocyanine, organic red, organic yellow, and white color pastes; among them, the white color paste is mainly titanium dioxide color paste, because titanium dioxide color paste has good Excellent light resistance, weather resistance, chemical stability, UV shielding and low price; it is widely used in the paint industry, and is used in the construction industry as artificial marble, ground terrazzo, and coloring agent for deep and light paint on interior and exterior walls . [0003] System color matching refers to an automatic color matching method that uses computer-controlled machinery instead of manual metering and injection of color paste. In recent...
