Example Embodiment

[0023] Example 1:

[0024] Weigh 21.5 grams of PR122, 2.8 grams of PR101, 2.05 grams of PV23, 0.13 grams of PBK7, and 1000 grams of CSC-B base material by weight. Mix the above materials uniformly, and then apply the resulting composition to the substrate evenly and evenly under the conditions of 50%±5% of ambient relative humidity and 23±2°C of room temperature by mechanical coating method. It is a metallic material or a non-metallic material, the wet film thickness of the coating is 250m, and then it is placed in a precision oven at 50±2℃ to dry for 3-4 hours to constant weight, taken out, and cooled to room temperature to obtain a color characterization.

Example Embodiment

[0025] Example 2:

[0026] Weigh 21.77 grams of PR122, 2.84 grams of PR101, 2.05 grams of PV23, 0.13 grams of PBK7, and 1000 grams of CSC-C base material by weight. The production process is the same as in Example 1.

Abstract

The invention discloses a composite expressing 10RP 3/6 pigment and a technical method for preparing a color characterizer by using the composite. The composite consists of components as follows: 995 to 1005 parts by weight of CSC-C base materials, 21.5 to 22.0 parts by weight of PR122 with 30 percent of pigments, 2.05 parts by weight of PV23 with 30 percent of pigments and 0.13 part by weight of PBK7 with 9 percent of pigments, wherein, the main component of the CSC-C base materials is acrylic copolymer, with the content ranging between 35 and 45 percent; the contrast ratio of the base materials ranges between 0.20 and 0.40, and the Stormer viscosity thereof is between 90 and 100KU; when the incident angle reaches 85 degrees, the glossiness of the base materials ranges between 5 and 10. With excellent weatherability, stability and ratio repeatability, the color characterizer adopts raw materials and processes that are in conformity with the environmental protection requirements and standards of low and zero VOC. Compared with the standard value set in the national standard theoretical model of the Chinese color system, the color characterizer has the advantages of minor color difference and high accuracy in color realization, and can be widely used in a variety of fields related to colors.

Description

【Technical field】 [0001] The present invention relates to a composition, in particular to a composition of pigments, and a technical method for preparing color representations from the composition. 【Background technique】 [0002] A color includes hue, lightness and chroma. As long as the hue, lightness and chroma are determined, a unique color can be determined. The Chinese color system GB / T 15608 stipulates that in the theoretical model of the Chinese color system, any color can be calibrated by the hue, lightness and chroma on the color plane, and given a certain label. The calibration method is to first write the hue H, then write the lightness V, write the chroma C after the slash, expressed as H V / C, take the color 10BG 5.5 / 6 as an example, 10BG means the hue, 5.5 means the lightness, and 6 means the color Spend. [0003] From the theoretical value in the theoretical model to the production process of the color representation, many important links such as color differ...
