Problems solved by technology

However, the oxidation process is difficult to control, and will produce more types and quantities of surface functional groups and by-products of the reaction, and the process is complicated, resulting in poor repeatability of the results.
[0009] The grafting modification method improves its dispersion and dispersion stability in water by grafting hydrophilic small molecular groups or polymer groups on the surface of carbon black. The steps are complicated and the cost is high.

[0042] (1) Heat 50-60 parts of deionized water to above 85°C, add 5-10 parts of suspending agent into it, stir and dissolve completely, then cool to normal temperature to obtain solution 1.

[0043] In order to achieve a better effect and ensure the quality of the carbon black water-based color paste, specifically heat the ionized water to 85-90°C.

[0044] (2) Add 1-5 parts of stabilizer to solution 1 to obtain mixed solution 2.

[0045] (3) Add 1-3 parts of defoamer into mixed solution 2 to obtain mixed solution 3.

[0046] (4) Add the mixed solution 3 into the high-speed mixer container.

[0047] (5) Add 20-30 parts of carbon black powder into the stirring container.

[0048] (6) Stir at a high speed for a period of time to disperse the carbon ...

Embodiment 1

[0055] In this example, carbon black water-based color paste is prepared by the following process:

[0056] (1) Weigh 100g of deionized water and heat it to 85°C for disinfection.

[0057] (2) Weigh 8g of carboxymethyl cellulose and add it to 56g of hot deionized water, stir to dissolve it, cool to normal temperature, replenish evaporated water, and pour it into a stirring pot.

[0058] (3) Weigh 3g of sodium chloride and add it to the stirring pot.

[0059] (4) Weigh 2g of silicon dioxide and add it into the stirring pot.

[0060] (5) Weigh 30g of carbon black powder and add it to the stirring pot.

[0061] (6) Stir the stirring pot at high speed to disperse the carbon black evenly, wherein the stirring speed is 1500-2000r / min, the temperature is 20-70°C, and the stirring time is 1.5-2h.

[0062] (7) Put the stirring pot into cold water and cool it to below 50°C, add 1 g of Nepalese propane, and stir for another 5 minutes to obtain a color slurry.

[0063] (8) Filter the ...

Embodiment 2

[0071] In this instance, prepare nano-carbon black dispersion slurry by following process:

[0072] (1) Weigh 100g of deionized water and heat it to 85 μg.

[0073] (2) Weigh 8g of PVP and add it to 56g of hot deionized water, stir to dissolve it, cool to normal temperature, add evaporated water, and pour it into a stirring pot.

[0074] (3) Weigh 3g of magnesium chloride and add it to the stirring pot.

[0075] (4) Weigh 2g of silicon dioxide powder and add it into the stirring pot.

[0076] (5) Weigh 30g of carbon black powder and add it to the stirring pot.

[0077] (6) Stir the stirring pot at high speed to disperse the carbon black evenly, wherein the stirring speed is 1500-2000r / min, the temperature is 20-70°C, and the stirring time is 1.5-2h.

[0078] (7) Put the stirring pot into cold water and cool it to below 50°C, add 1 g of Nepalese propane, and stir for another 5 minutes to obtain a color slurry.

[0079] (8) Filter the color slurry through a 200-mesh filter c...

Abstract

The invention discloses carbon black water-based color paste with high carbon black content and a preparation method thereof. The preparation method comprises the steps that deionized water is heated to the temperature above 85 DEG C, suspending agents are added to water, and stirring is conducted to make the suspending agents fully dissolved; then carbon black powder is added, defoaming agents and stabilizers are added, even stirring is conducted, the stirring speed is adjusted, after stirring is conducted for a period of time, preservative is added, even stirring is conducted, and the carbon black water-based color paste is obtained. The method is simple in operation technology, the prepared carbon black water-based color paste is high in color powder content, low in settleability, low in viscosity and capable of being stably stored for a long time, and the carbon black water-based color paste can be directly used in a formula without being affected by additional mechanical force.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a carbon black slurry. Background technique [0002] In the traditional production process, carbon black is mostly used directly, causing dust to fly and polluting the environment; at the same time, production operators are easy to inhale dust, which greatly affects the health of the operators. [0003] In addition, under normal circumstances, carbon black is not easy to mix uniformly with polymer materials due to its small particle size and large specific surface area. Especially in the case of a large amount, it often causes uneven dispersion of carbon black, difficult to add and other processing difficulties. [0004] However, if the corresponding carbon black slurry is used, the dust caused by carbon black can be avoided, and the environment can be polluted. At the same time, the operator can avoid inhaling the dust, protect the health of the operator, and can simplify the...
