Description

TECHNICAL FIELD

[0001] The present application relates to the field of painting, in particular to watercolor painting pigments and a method for making the same. BACKGROUND

[0002] Watercolor painting pigments originated from traditional Chinese water shadow painting, and were later transmitted to Turkey along the Silk Road. The watercolor painting pigments in Turkey are usually mixed with natural pigments, prepared "water medium", and cow bile at a specific temperature for brewing. The advantages of the watercolor painting pigments in Turkey are bright colors and natural detail portrayal, and the disadvantages are long brewing time, low yield, and the need to adjust the ratio of water and cow bile according to different temperatures and environments.

[0003] Traditional watercolor painting pigments on the market are usually made by mixing polyvinyl alcohol with hydroxy cellulose, or sodium alginate thickening agent, and pigments are prepared mainly from acrylic resin, with the addition of thickening agent, color powder, humectant, dispersant, etc. Some also add latex and other materials, and are prepared by grinding, stirring, mixing, and thickening. The advantages are simple process and large yield, and the disadvantages are long adjustment time of the paint liquid, uneven pigment diffusion, uncontrollable diffusion range, and easy sedimentation.

[0066] Example 5

[0067] Watercolor paint, comprising the following raw materials in weight percentage: 59.7% water, 7% wax, 3% peregal, 6% cetyltrimethylammonium bromide, 1% polyvinylpyrrolidone, 4% acidified castor oil, 0.8% sodium alginate, 1.5% organic amine, 1% alkali swelling thickener, 8% color powder, 3% propylene glycol, 2% glycerol, 3% dispersant, wherein the wax is Honeywell AC-6A with a molecular weight of 5000, the color powder is red PR170, blue PB14, and yellow PY3, and the alkali swelling thickener is ASE60.

[0072] Comparative Example 1

[0073] like Figures 5-8 The image shown is of commercially available marbling paint. Its packaging indicates that its ingredients are: deionized water, environmentally friendly resin, glycerin, thickener, and pigment.

[0074] Comparative Example 2

[0075] The only difference between this comparative example and Example 5 is that hydrogenated castor oil was not added during preparation.

[0076] like Figure 1 and Figure 5 As shown, compared with Comparative Example 1, Example 2 added Pingpingjia and wax. It can be found that the marbling pigment of Comparative Example 1 is easy to settle and requires high operation. However, the marbling solution prepared by Example 2 can be easily suspended and the suspension time is longer. The marbling pigment of Comparative Example 1 begins to precipitate and split after being suspended on the paint solution for 30 minutes, while the suspension time of Examples 1-5 can reach 2-3 hours without settling. The suspension performance of the embodiments of the present invention is better.

[0077] like Figure 2 and Figure 6As shown, compared with Comparative Example 1, the watercolor painting pigment prepared in Example 3 diffuses more gently and more uniformly, and the diffusion area can be larger, and as the diffusion size increases, the surface does not appear to be precipitated, while the commercially available watercolor painting pigment gradually becomes uneven as the diffusion area increases, and even begins to appear split and precipitated, and the watercolor painting pigment of the example diffuses more uniformly.

[0078] As shown in Figure 3 and Figure 7 As shown, compared with Comparative Example 1, the watercolor painting pigment prepared in Example 4 diffuses more uniformly, with no obvious jagged edges, and can achieve a more beautiful effect when painting, while the watercolor painting pigment of Comparative Example 1 is prone to uneven edges and has higher operating requirements.

[0079] As shown in Figure 4 and Figure 8 As shown, compared with Comparative Example 1, the watercolor painting pigment prepared in Example 4 diffuses more uniformly, with no obvious jagged edges, and can achieve a more beautiful effect when painting, while the watercolor painting pigment of Comparative Example 1 is prone to uneven edges and has higher operating requirements.

[0080] In addition, the precision colorimeter of model CS-200 was used to detect the watercolor painting prepared from the watercolor painting pigments of Example 5 and Comparative Example 2, and the results are shown in Table 1:

[0081] Table 1

[0082]

[0083] Wherein, L represents black and white or light and dark, + represents white / light bias, and - represents dark / black bias;

[0084] a represents red and green, + represents red bias, and - represents green bias;

[0085] b represents yellow and blue, + represents yellow bias, and - represents blue bias;

[0086] As shown in Table 1, the color of Example 5 is more vibrant than that of Comparative Example 2.

[0087] In addition to the paper sheets in the above examples, the transfer material in the present application can also use gypsum, stone, bamboo sheets, silk scarves and other materials with water absorption properties.

[0088] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application.
