Problems solved by technology

[0003] At present, the transparent iron oxide colorants used in the market are divided into water-based colorants and solvent-based colorants, which bring inconvenience to customers; and the above-mentioned colorants, especially solvent-based permeable iron colorants, contain a large amount of VOC components, which is not good for the environment. Therefore, it is necessary to develop a water-oil universal transparent iron oxide color paste

Embodiment 1

[0017] According to Example 1 in Table 1, add deionized water, bactericide, propylene glycol, CT-115A, EFKA-1502, BYK-180 according to the formula weight ratio, stir evenly at a speed of 500r / min in a high-speed disperser, and then stir at a speed of 1000~ Add transparent iron oxide yellow powder at a high speed of 1200r / min, disperse at a high speed for 45 minutes, and then turn to a cone or rod sand mill for circular grinding for 6-10 hours until the fineness 2 Stir for 15-30 minutes; add BYK-024 at a low speed, and after the viscosity and fineness are qualified, filter and pack to obtain nano-transparent iron oxide yellow slurry for water and oil.

Embodiment 2

[0018] Example 2, Example 3 The preparation steps refer to Example 1.

[0019] According to relevant national standards, the performance of the water-oil universal nano transparent iron oxide yellow paste of the present invention was tested, and the test results are shown in Table 2.

[0020] Table 2 Basic performance test results of water-oil universal nano-transparent iron oxide yellow slurry

[0021]

[0022] Use the compatibility test method to test the versatility of the color paste of the present invention, specifically: add 5% of the color paste to the coatings made of various emulsions and resins, and use a 200 μm wet film device after mixing evenly. The coated film board is tested by the finger grinding method. After drying, there is no floating or blooming phenomenon in the finger grinding area, and the color difference between the finger grinding area and the non-grinding area is △E≤0.5, which is considered qualified.

Abstract

The invention relates to a preparation method of water and oil applicable, nano transparent iron oxide yellow paste. The yellow paste is composed of following raw materials in percentage by weight: 10% to 35% of deionized water, 3% to 10% of cosolvent, 1% to 3% of surface conditioning agent, 15 to 25% of dispersion resin, 8% to 20% of wetting dispersant, 0.1% to 0.6% of pH value conditioning agent, 20% to 40% of transparent iron oxide yellow, 0.1% to 1.0% of thickening and anti-settling agent, 0.1% to 0.3% of bactericide, and 0.2% to 1% of antifoaming agent. The particle size D50 of the water and oil applicable nano transparent iron oxide yellow paste is smaller than 1 [mu]m. The nano transparent iron oxide yellow paste has the characteristics of storage stability, transparency, compatibility and environmental-friendliness, is capable of replacing metal complex dye, and is widely applied to the areas of aqueous or oily woodenware paint, automobile finish, plastic paint, metal paint, construction paint, children toys, painting materials, high temperature glass printing ink, and the like.

Description

technical field [0001] The invention relates to a preparation method of transparent iron oxide yellow slurry, in particular to a nano transparent iron oxide yellow slurry universal for water and oil. Background technique [0002] As we all know, iron oxide pigments have the best light stability, and transparent iron oxide with nanometer particle size has a stronger ability to absorb ultraviolet rays. Therefore, transparent iron oxide pigments are not only optically stable, but also improve various high Anti-aging properties of polymers. Transparent iron oxide with nanometer particle size changes the absorption and scattering properties of ordinary iron oxide in the visible light part, so it has high saturation and coloring strength. Transparent iron oxide maintains the chemical composition and crystal form of iron oxide pigments, so it has good chemical stability, and has excellent acid resistance, alkali resistance, solvent resistance, water resistance and oil resistance. ...
