no. 1 example

[0028] A color paste provided in this embodiment comprises the following raw materials in parts by weight: 38.78 parts of water, 15 parts of solvent, 24 parts of surfactant, 0.5 part of light stabilizer, 2 parts of pH regulator, and 0.2 part of bactericide , 0.02 parts of defoamer and 20 parts of pigments.

[0029] Wherein, the solvent includes 2 parts of acetone, 2.5 parts of ethanol, 5 parts of propylene glycol, 5 parts of polypropylene glycol and 0.5 part of isopropyl alcohol, and the surfactant includes 1 part of wetting agent (SINPOLS1306), fatty alcohol polyoxyethylene ether (980 ) 2 parts, hydrophobic ammonium salt dispersant (Disperbx H5028) 5 parts, polymer block dispersant 16 parts.

no. 2 example

[0031] A color paste provided in this embodiment comprises the following raw materials in parts by weight: 18.28 parts of water, 30 parts of solvent, 28 parts of surfactant, 1.5 parts of light stabilizer, 2 parts of pH regulator, and 0.2 part of bactericide , 0.02 parts of defoamer and 20 parts of pigments.

[0032] Wherein, the solvent includes 5 parts of acetone, 5 parts of ethanol, 10 parts of propylene glycol, 8 parts of polypropylene glycol and 2 parts of isopropyl alcohol, and the surfactant includes 1 part of wetting agent (SINPOLS 1306), fatty alcohol polyoxyethylene ether ( 980) 2 parts, hydrophobic ammonium salt dispersant (Disperbx H5028) 5 parts, polymer block dispersant 20 parts.

no. 3 example

[0034] The manufacturing process of a color paste provided in this embodiment comprises the following steps: mixing water with a dispersant and a wetting agent for 10 minutes at a speed of 600 r / min, and then mixing with a pigment for 1 hour at a speed of 2600 r / min to obtain the first A mixed solution.

[0035] The solvent and the light stabilizer were mixed according to the ratio of 99:1 WT% for 20 minutes at a rotation speed of 400 r / min to obtain a second mixed solution. The first mixed solution was mixed with the second mixed solution for 30 minutes at a speed of 400 r / min to obtain a third mixed solution, which was then mixed with a pH regulator, bactericide and defoamer for 1 hour at a speed of 200 r / min.

Abstract

The invention relates to the field of coating, and provides a color paste. The color paste comprises a light stabilizer, which can shield or absorb the energy of ultraviolet rays, but does not changeitself and can prevent the destruction of sunlight or other harmful ultraviolet light. Through use of a surfactant and a solvent in the color paste, the stability of the color paste is improved, and through addition of a high molecular dispersing agent, the compatibility of the color paste is wider; in addition, the invention further provides a preparation technology of the color paste. By the preparation technology, the color paste with good light resistance, stability and compatibility can be prepared.

Description

technical field [0001] The invention relates to the field of paint, and in particular to a color paste and a manufacturing process thereof. Background technique [0002] The traditional paint coloring is to use pigment powder to add directly to the paint, some simply make the pigment into slurry, and then add it to the paint to color the paint. There are certain disadvantages in doing so, for example, poor color reproducibility, or uneven coloring. Because there is no professional technology and process, the pigment particles are relatively coarse, the coloring power is not high, and the pollution is serious. When it is added to the paint, the light resistance and weather resistance of the paint film are poor, and it is easy to fade. [0003] With the intensification of market competition, the demand for high-end coatings is increasing, and color paste manufacturers will emerge immediately. Color paste, that is, a kind of pigment concentrate, is developed by using differen...
