Example Embodiment

[0022] Example 1:

[0023] Weigh 7.91 grams of PG7, 4.7 grams of PB15:3, 18.32 grams of PW6, 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. It is a metallic material or a non-metallic material. The wet film thickness of the coating is 250μm, then it is dried in a precision oven at 50±2℃ for 3~4h to constant weight, taken out, and cooled to room temperature to obtain a color characterization object.

Abstract

The invention discloses a composition expressing 2.5B4.5/10 pigments and a process for preparing a color characterization object by the same. The composition comprises the following components in parts by weight: 995-1005 parts of CSC-C base materials, 7.8-8.0 parts of PG7, 4.7 parts of PB15:3 and 18.1-18.5 parts of PW6, wherein the content of pigment in the PG7 is 20 percent, the content of pigment in the PB15:3 is 27 percent and the content of pigment in the PW6 is 65 percent. The main component of the CSC-C base materials is acrylic copolymer which has the content of 35-45 percent. The base materials have the contrast ratio of 0.20-0.40, the Stormer viscosity of 90-100KU and the glossiness of 5-10 degrees when the incident angle is 85 degrees. A color characterization object of the invention has high weather resistance and stability as well as good proportion repeatability; the used raw materials and process accord with environment protection requirement and standard of low VOC and zero VOC; and the color characterization object has little aberration compared with the standard value in a national standard theoretical model of China Color System, and high accuracy of color implementation, and can be widely applied to fields 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 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 saturation C after the slash, expressed in HV / C, take the color 10BG 5.5 / 6 as an example, 10BG represents the hue, 5.5 represents the lightness, and 6 represents the color Spend. [0003] From the theoretical value in the theoretical model to the production process of the color representation, many important links su...
