Problems solved by technology

[0005] At present, the content of volatile organic components (VOC), heavy metals, and nonylphenol polyoxyethylene ether (APEO) in commercially available water-based machine color pastes is relatively high. Most paint manufacturers have begun to introduce low-VOC or even zero-VOC basic latex paints. The matching water-based machine color paste for low-VOC and zero-VOC paint has become a vacancy in the market

Embodiment Construction

[0028] The formula of the embodiment of the present invention is referring to Table 1: Table 1: (unit: percentage by weight)

[0029]

[0030] The preparation method of nano-modified environment-friendly iron oxide machine color paste is carried out according to the following steps:

[0031] a) Put water, wetting and dispersing agent, moisturizing co-solvent, and PH value regulator into the dispersion container, adjust the rotation speed of the disperser to 500-700r / min, and obtain a uniform solution after 15 minutes, in which 10% of the total amount is reserved spare water;

[0032] b) Add water-based nano-pigment slurry, water-based grinding resin, and iron oxide pigment to the above mixed solution, adjust the dispersion speed to 800-1000r / min, and grind after 20 minutes;

[0033] c) Grinding with a horizontal sand mill, using a laser particle size analyzer to control the particle size distribution of the color paste to a d99 less than 1um in the middle process, stop gri...

Abstract

The invention discloses a color paste for a nanometer modified environmentally-friendly ferric oxide machine, which is composed of ferric oxide pigment, aqueous nanometer concentrated pulp, aqueous grinding resin, wetting dispersant, a pH value regulator, moisturizing cosolvent, defoamer and water. The raw materials are counted in percentage by weight: the ferric oxide pigment: 30-50% of the aqueous nanometer concentrated pulp, 10-15% of the aqueous grinding resin, 3-7% of the wetting dispersant, 6-15% of the pH value regulator, 0.1-0.5% of the moisturizing cosolvent, 10-12% of defoamer and 0.1-0.3% of the balance of water. The ferric oxide color paste obtained by the invention has the functions of environment protection, health care and convenient use. The ferric oxide color paste obtained by the invention has favourable intermiscibility with majority of emulsion paint and wider popularizing range, does not flocculate, precipitate or seriously distribute water if placed for two years, and has favourable storage stability.

Description

technical field [0001] The invention relates to a water-based color paste, in particular to a nano-modified environment-friendly iron oxide machine color paste used for mechanical color matching. Background technique [0002] With the rapid development of the paint industry, people choose paint not only for its decoration and protection, but also for the matching of paint colors. In order to meet people's needs for personalized color matching, well-known brand paint manufacturers continue to expand their sales channels in the civilian market , The fast and accurate on-site color matching service has become another highlight of retail stores in addition to brand benefits. Therefore, the development prospects of computer color matching systems (POS color matching systems) in the civil market for architectural coatings are becoming more and more promising. [0003] The color matching system is based on computer simulation technology. The color paste is added to the basic white ...
