Embodiment 1

[0020] Add 5.0g of dispersant Dispersogen 2774, 0.2g of anti-foaming and anti-foaming agent Defoamer155, 10.0g of water-retaining antifreeze agent propylene glycol, and 0.2g of preservative Dehygant LFM into 41.2g of water. After the dispersion is uniform, slowly add 40.0g of organic red 254 pigment, and then Disperse for half an hour, after sanding for 2 hours (general fineness is less than 20μm), add 0.2g of PH regulator AMP-95 and 0.2g of defoamer Defoamer 334 for slow defoaming, and finally add 3% of 6.7g of HBR250 Pre-gel (the moisture contained therein is pre-calculated in the total water content), and evenly dispersed to obtain an organic red water-based color paste with a pigment content of 41.2%.

Embodiment 2

[0022] Add 3.0g of dispersant Dispersogen 2774, 0.3g of anti-foaming and anti-foaming agent Defoamer155, 4.0g of water-retaining antifreeze agent propylene glycol, and 0.3g of preservative Dehygant LFM into 62.5g of water. After the dispersion is uniform, slowly add 30.0g of organic red 254 pigment, and then Disperse for half an hour, after sanding for 2 hours (general fineness is less than 20μm), add 0.1g of PH regulator AMP-95 and 0.4g of defoamer Defoamer 334, slow defoaming, and finally add 3% of 13.3g of HBR250 Pre-gel (the moisture contained therein is pre-calculated in the total water content), and evenly dispersed to obtain an organic red water-based color paste with a pigment content of 29.7%.

Embodiment 3

[0024] Add 8.0g of dispersant Dispersogen 2774, 0.4g of anti-foaming and anti-foaming agent Defoamer155, 7.0g of water-retaining antifreeze agent propylene glycol, and 0.1g of preservative Dehygant LFM into 50.0g of water. After the dispersion is uniform, slowly add 35.0g of organic red 254 pigment, and then After dispersing for half an hour, after sanding for 2 hours (generally, the fineness is less than 20μm), add 0.4g of PH regulator AMP-95 and 0.3g of defoamer Defoamer334 for slow defoaming, and finally add 3.3g of HBR250 with 3% pre- Gel (the moisture contained therein is pre-calculated in the total water content), and after being uniformly dispersed, an organic red water-based color paste with a pigment content of 34.9% is obtained.

Abstract

The water-base organic red color paste consists of dispersant Dispersogen-2774 3.0- 8.0 weight portions, bubble inhibitor Defoamer-155 0.2-0.4 weight portions, defoaming agent Defoamer-334 0.2-0.4 weight portions, organic red 254 pigment 30.0-40.0 weight portions, pH regulator AMP-95 0.1-0.4 weight portions, antiseptic Dehygant LFM 0.1-0.3 weight portions, moisture holding antifreeze agent propylene glycol 4.0-10.0 weight portions, thickener HBR250 0.1-0.4 weight portions, and water 41.2- 62.5 weight portions. The water-base organic red color paste has certain hydrophobicity, high compatibility with latex paint for outer wall, high coloring power, high storage stability, high weather resistance, high light and heat resistance and high acid and alkali resistance, and is used mainly for coloring latex paint for outer wall.

Description

【Technical field】 [0001] The invention relates to the field of coatings, in particular to an organic red water-based color paste. 【Background technique】 [0002] At present, a large amount of water-based colorants have been used in the color matching of latex paints. The pigments used include inorganic pigments such as iron oxide red and iron yellow, and various organic pigments such as phthalocyanine blue, organic red, and organic yellow. Organic red pigments have bright colors and strong tinting power, and occupy an important position in the color paste system. However, the use of organic red pigment R254 in architectural coatings is limited due to its high price. [0003] With the rapid development of architectural coatings in recent years and the improvement of people's living standards, people are paying more and more attention to the application of high-quality water-based colorants. R254 has been widely used in In water-based color paste. 【Content of invention】 ...
