Embodiment 1

[0023] Weigh 3.37 grams of PV23, 4.34 grams of PB15:3, 0.34 grams of PBK7, 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.

Embodiment 2

[0025] Weigh 3.23 grams of PV23, 4.54 grams of PB15:3, 0.34 grams of PBK7, and 1000 grams of CSC-B base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a 2.5PB6 / 8 pigment expression compound and a technique to prepare a color characterization substance from the compound. The compound contains(based on weight portion): 995-1005 portions of CSC-B base material, 3.05-3.52 portions of PV23 containing 30% dye, 4.24-4.54 portions of PB15:3 containing 27%dye, and 0.34 portions of PBK7 containing 9%dye. The main component of CSC-B base material is acrylic copolymer and the content is 30-40%. TiO2 is chosen to be used as main white dye, at content of 8-12%. When the base material is at contrast ratio of 0.78-0.82, Stormer viscosity of 90-100KU and incident angle of 85, the glossiness of the base material is 5-10. The color characterization substance is of good weatherability and stability and good proportioning reproducibility, and the materials and the process meet the requirement and standard of low VOC and no VOC for environment protection. The color characterization substance has small differences with the standard colors in national standard theory model of the Chinese color system and is precise in color realization, thus widely applicable in various fields relevant with 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...
