Embodiment 1

[0023] Weigh 0.16 grams of PBK7, 1.54 grams of PY138, 1.16 grams of PG7, and 1000 grams of CSC-A base material. Mix the above raw materials, and then apply the mixed composition evenly and evenly on the coated paper under the environmental conditions of relative humidity of 50%±5% and room temperature of 23±2°C. The thickness of the wet film of the coating is 250m, and then placed in a precision oven at 50±2°C for 3 to 4 hours to a constant weight, then taken out, cooled to room temperature, and obtained a physical color block.

Embodiment 2

[0025] Weigh 0.17 grams of PBK7, 1.55 grams of PY138, 1.18 grams of PG7, and 1000 grams of CSC-A base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Weigh 0.18 grams of PBK7, 1.58 grams of PY138, 1.20 grams of PG7, and 1005 grams of CSC-A base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a composition of 5G 8.5/2 pigment and the way to use the invention to prepare real color block. According to weight account, the composition comprises 995 to 1005 portions of CSC-A base material; 0.14 to 0.18 portion of PBK7 having the pigment content of 9%; 1.50 to 1.58 portions of PY138 having the pigment content of 27%; 1.10 to 1.20 portions of PG7 having the pigment content of 20%. The main component of the CSC-A base material is acrylic copolymer, and the content ranges from 30% to 40%. TiO2 is used as the main white pigment, and the content ranges from 18% to 22%. The contrast ratio of the base material ranges from 0.90 to 0.96; the stormer viscosity ranges from 90 to 100KU; when the incident angle is 85 DEG, the glossiness ranges from 5 to 10. The invention has the advantages that, the composition has high weatherability and stability, and good ratio reproducibility; the adopted materials and technological process meet the environment-friendly requirements and standards of low VOC and zero VOC; compared with the standard value of the theoretical model in Chinese Color System, the real color block has very small color difference, and the accurate degree of the realization of color is high; meanwhile the manufacture technology is refined, and the practical value is extremely strong.

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, 10B6 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...
