Abstract

The present invention provides a compound of 5GY 8.5 / 3 pigment and a method of preparing real color block, the composition of the compound by weight is: CSC-A base material 995-1005 portions; PY138, the content of the pigment is 27%, 4.34-4.44 portions; PG7, the content of the pigment is 20%, 0.84-0.94 portions; PY42, the content of the pigment is 60%, 6.08-6.18 portions. The CSC-A base material is mainly composed of acrylic copolymer, the content is 30-40%. TiO2 is selected as a main white pigment, the content is 18-22%. The contrast ratio of the base material is 0.90-0.96, stormer viscosity is 90-100KU, when the incident angle is 85, the lossiness is 5-10. The compound of the invention has high weatherability and stability, better ratio reproducibility, the raw material and the process are in accordance with environmental protection requirement and standard of lower VOC and non-VOC; the real color block has a small color difference compared with the standard value in the theoretical model, the accurate degree of the color is high, having simple process, and high practical value.

Description

【Technical field】 [0001] The invention relates to a composition, in particular to a pigment composition, and a physical color block prepared by using 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 actual color block, many important links such as color difference ΔE, raw materials, form...
