Embodiment 1
[0022] Weigh 10.42 grams of PG7, 16.87 grams of PB15:3, and 1000 grams of CSC-B base material. Mix the above materials evenly, and then apply the obtained composition on the substrate evenly and evenly by mechanical coating under the conditions of relative humidity of 50%±5% and room temperature of 23±2°C. It is metallic or non-metallic material. The wet film thickness of the coating is 250m, and then placed in a 50±2°C precision oven to dry for 3-4h to constant weight, take it out, cool to room temperature, and obtain the color characterization.

Abstract
The invention discloses a composition of a 7.5B 5.5 / 11 pigment, which consists of 995 to 1005 parts by weight of CSC-B base material; 16.8 to 16.95 parts by weight of PB15:3 with the pigment content of 27 percent; and 10.3 to 10.55 parts by weight of PG7 with the pigment content of 20 percent. The main ingredient of the CSC-B base material is acrylic acid copolymer, the content is 30 to 40 percent and the range of average molecular weight is 0.15 to 0.2 million. TiO2 is selected as a main white pigment, and the content is 8 to 12 percent. The contrast ratio of the base material is 0.78 to 0.82, the Stormer viscosity is 90 to 100KU, and the gloss is 5 to 10 when the incident angle is 85 degrees. A color characterizer of the invention has good weatherability, stability and reproducibility of mixture ratio, and the raw materials and the process are in line with the requirements and the standards on low VOC and zero-VOC environmental protection; and compared with the standard value in a national standard theory model of the Chinese color system, the color characterizer has small color difference and high accuracy of color realization, thereby being capable of being widely applied in a plurality of fields which are related to the color.
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 15608-1995 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 d...
