Example Embodiment

[0022] Example 1:

[0023] Weigh 0.22 grams of PBK7, 0.84 grams of PY138, 0.51 grams of PG7, and 1000 grams of CSC-A base material by weight. Mix and mix the above-mentioned raw materials uniformly, and then apply the mixed composition to the coated paper evenly and smoothly under the environmental conditions of 50%±5% relative humidity and 23±2°C at room temperature. On the top, the wet film thickness of the coating is 250m, then it is placed in a precision oven at 50±2℃ to dry for 3~4h to constant weight, take it out, and cool to room temperature to obtain the actual color block.

Example Embodiment

[0024] Example 2:

[0025] Weigh 0.23 grams of PBK7, 0.82 grams of PY138, 0.50 grams of PG7, and 1000 grams of CSC-A base material by weight. The production process is the same as in Example 1.

Abstract

The invention discloses a compound of 5G 8.5/1 pigment and a method in preparation of a real color block. In weight ratio, the compound comprises 995 to 1005 portions of CSC-A base material, 0.20 to 0.24 portion of PBK7 with pigment content of 9%, 0.80 to 0.88 portion of PY138 with pigment content of 27%, and 0.47 to 0.55 portion of PG7 with pigment content of 20%. The main component of the CSC-A base material is acrylic copolymer with content percentage ranging from 30% to 40%. TiO2 is used as the primary white pigment with content percentage ranging 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 angle of incidence is 85 DEG, the glossiness ranges from 5 to 10. The invention has the advantages that the compound has high weatherability and stability, and good composition ratio reproducibility; the raw materials and technological process meet the environmental requirements and standards of low VOC and zero VOC emission; compared with standard values of the theoretical model proposed by Chinese Color System, the real color block has a very small color difference but high accuracy of color realization; additionally with simplified processing technology, the real color block is of great 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...
