preparation example Construction

[0035] A method for preparing anti-bleeding and zero-VOC colorant specially used for colorful paints. The specific steps are as follows: first add deionized water into the reaction kettle, and then add humectants, preservatives, wetting agents, dispersants, and defoamers to disperse After 5 minutes, put in protective glue, adjust the pigment dispersion speed to 1000-1500 rpm, and disperse for 15-20 minutes to obtain a slurry dispersion; then use a pump to input the slurry dispersion into a sand mill for grinding, and the grinding speed Adjust to 800-1000 rpm, grind and disperse for 3-5 times, stop grinding until the slurry fineness is less than 5 microns, adjust the viscosity range to 70-90KU, filter and pack.

[0036] The present invention uses a modified aluminum-magnesium silicate or a modified sodium-magnesium-lithium silicate as a protective glue, which can form a potential isolation with deionized water and form a "card house structure", such as figure 1 As shown, the ad...

Abstract

The invention relates to a special bleeding-preventing zero-VOC color paste for multicolor paints. The color paste is composed of deionized water, a humectant, a preservative, a wetting agent, a dispersing agent, a defoaming agent, protective glue, pigment and a thickening agent. The color paste is used for color matching of the multicolor paints. The color paste can effectively prevent multicolor points from bleeding mutually, the color of the color points is independent and stable, the color retention of the color is good, Meanwhile, the color paste disclosed by the invention has the characteristics of high environmental friendliness, no APEO, zero VOC and the like.

Description

technical field [0001] The invention relates to the field of color paste, in particular to an anti-bleeding zero-VOC color paste specially used for colorful paints and a preparation method thereof. Background technique [0002] In the color mixing of colorful paints, we often encounter customer complaints caused by bleeding of color spots, poor stability of color particles, inconsistent effect with the model after construction, or inconsistent effects between batches due to color bleeding and unstable color particles. [0003] At present, the general water-based color pastes on the market are difficult to meet the color matching of colorful paints. On the one hand, it is the problem of color particle bleeding, and the other solution is that the traditional water-based color pastes contain a large amount of volatile organic compounds (VOC), such as ethylene glycol or propylene glycol. , these substances will cause air pollution. Contents of the invention [0004] (1) Techn...
