Embodiment 1

[0022] Weigh 10.41 grams of PG7, 1.8 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 10BG7 / 8 pigments, which comprises the following components in parts by weight: 995-1005 parts of CSC-B base materials, 10.32-10.51 parts of PG7 and 1.76-1.83 parts of PB15:3, wherein the content of pigment in the PG7 is 20 percent and the content of pigment in the PB15:3 is 27 percent. The main component of the CSC-B base materials is acrylic copolymer which has the content of 30-40 percent and the average molecular weight of 1.5-2.0 million. TiO2 is selected as a main white pigment which has the content of 8-12 percent. The base materials have the contrast ratio of 0.78-0.82, the Stormer viscosity of 90-100KU and the glossiness of 5-10 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 15608-1995 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...
