Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.

It contains -7 parts by weight, the xanthan gum is contained 0.01 to 5 parts by weight based on 100 parts by weight of the pigment. Preferably, the pigment and the distilled water are mixed in a weight ratio of 1: 1 to 1: 2.5. The pigment composition may further include glacial acetic acid or citric acid, the glacial acetic acid or citric acid is preferably contained 0.1 to 15 parts by weight based on 100 parts by weight of the xanthan gum.
In the pigment composition for hand painting according to the preferred embodiment of the present invention, sodium-silicate for improving dispersibility of the pigment composition is added to a slurry in which distilled water and a color-pigmented pigment are mixed, but the sodium-silicate is Adding 0.1 to 7 parts by weight with respect to 100 parts by weight of the pigment, and adding the laponite to form the pigment composition in a gel state and to enhance stability to the sodium-silicate-added mixture, wherein the laponite Is added in an amount of 0.1 to 7 parts by weight based on 100 parts by weight of the pigment, and xanthan gum is added to the mixture to which the laponite is added to enhance the stability of the pigment composition. It comprises the step of adding 0.01 to 5 parts by weight relative to. Preferably, the pigment and the distilled water are mixed in a weight ratio of 1: 1 to 1: 2.5. It may further comprise the step of adding glacial acetic acid or citric acid to the pigment composition, the glacial acetic acid or citric acid is preferably added to contain 0.1 to 15 parts by weight based on 100 parts by weight of the xanthan gum.
In order to optimize the dispersion of the hand-painted pigment composition, the optimum dispersant and the amount of the dispersant were determined through dispersant-specific experiments. The dispersant may include sodium silicate, sodium polyacrylic acid (Na-PAA), sodium polymethyl methacrylate (Na-PMAA), ammonium polyacrylic acid ( NH 4 -PAA) was selected. At this time, while fixing the amount of the solid content (pigment) to 35% and increasing the amount of the dispersant is added, after preparing the pigment composition for painting, the dispersion efficiency was measured by observing the degree of precipitation over time.
Among the dispersants used in the experiment, the optimum dispersing efficiency was sodium-silicate (Na-silicate) when 0.5 to 3 parts by weight of solids was added.
Laponite and Xanthan Gum were added as second additives to improve the stability of the pigment composition for hand painting.
Laponite is sodium magnesium silicate, which enhances the dispersibility of the pigment composition and forms a gel state, thereby enhancing the stability of the pigment composition for hand painting.
The laponite is a disk-like synthetic clay mineral having a thickness of 1 nm and a diameter of 25 nm. Laponite is easily dissolved in water and has a strong electric force in water to maintain dispersion. As the concentration of laponite increases, it becomes gel over time. This gel state is shown by the surface and the edges of the laponite particles have different charges in water to form a structure.
Xanthan Gum is a natural gel-based ingredient derived from sugar cane and is mainly used to make hair gels. Because it is soluble in distilled water, it is dissolved in the water base. It is mainly used to make gel type cosmetics, and when added to cream, it has a good spreading texture.
Xanthan Gum is also a thickener with a very large molecular structure that enhances the stability of pigment compositions for hand painting. The xanthan gum (Xanthan Gum) is a pulverized carbohydrate phytopathogens of the jintomonisu Campestris bacteria, a high-molecular polysaccharide test material obtained by pure culture fermentation of carbohydrates in isopropyl alcohol and dried and pulverized glucose, manos and It is a mixture consisting of sodium, potassium and calcium salts of glucuronic acid. Pale yellow powder, soluble in water, aqueous solution is neutral, insoluble in ethanol.
Xanthan Gum is dispersed in cold water and dissolved in hot water, with little difference in viscosity depending on the temperature at which it is dissolved. It has excellent heat resistance, and especially if glacial acetic acid or citric acid is present, the viscosity decreases even if heated. Xanthan Gum has a good viscosity compared to other thickeners and gradually increases in viscosity with concentration.
The pigment composition for handpainting of the present invention will be described in more detail through the following examples.
≪ Example 1 >
In order to prepare a pigment composition for hand painting, the mixture was mixed with 35 wt% of the pigment (solid content) and 65 wt% of distilled water. Sodium silicate (Na-silicate) was added 0.5 to 3 parts by weight based on solids, and laponite and Xanthan Gum were added to 0.5 to 3 parts by weight and 0.1 to 2 parts by weight, respectively. . Sodium silicate (Na-silicate) was added first to ensure dispersibility and then in the order of laponite and Xanthan Gum.
Table 1 below shows the composition ratio of the additives added to the pigment composition for hand painting.
Figure 2 is a photograph showing the dispersion state after 30 days have passed the pigment composition for hand painting prepared according to Example 1. '①' shown in FIG. 2 refers to a pigment composition for hand-painting with a composition containing 1 part by weight of sodium-silicate, 1 part by weight of laponite, and 0.2 part by weight of xanthan gum. , '②' refers to the pigment composition for hand-painting with the addition of 1 part by weight of sodium silicate (Na-silicate), 1 part by weight of laponite, and 0.4 part by weight of Xanthan Gum. Is for a pigment composition for hand-painting, in which 1 part by weight of sodium-silicate, 1 part by weight of laponite, and 0.6 parts by weight of xanthan gum are added. It relates to a pigment composition for hand-painting, wherein 1 part by weight of silicate (Na-silicate), 1 part by weight of laponite, and 0.8 part by weight of Xanthan Gum are added.
Compared with the conventional paint, the phase separation state did not change significantly even after 30 days. This is considered to be a result of the dispersion force by the strong electromagnetic force of laponite.
