Embodiment 1

[0023] Weigh 22 grams of PY74, 2.28 grams of PG7, 14.61 grams of PY42, 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 composite for expressing 2.5GY 7.5 / 6 pigment and a technical method for preparing color representation material by using the composite. The composite comprises, by weight parts, CSC-B base material 995 to 1005 parts; PY74 with pigment content 40 percent, 21 to 23 parts; PG7 with pigment content 20 percent, 2.23 to 2.33 parts; and PY42 with pigment content 60 percent, 14.01 to 15.21 parts; wherein the CSC-B base material mainly contains acrylic acid polymer 30 to 40 percent; and TiO2 8 to 12 percent is selected as the main white pigment. The color representation material has good weathering resistance and stability and good proportion reproducibility, and the used material and the process meet the requirement for low-VOC and zero-VOC environmental standard. Compared with the standard value of national standard theoretical model of Chinese color system, the color representation material has less color difference and higher accuracy degree for color representation, and can be widely used for a plurality of fields relevant to 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...
