Embodiment 1

[0023] Weigh 0.05 grams of PBK7, 5.60 grams of PY138, 0.18 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 wet film thickness of the coating is 250 μm, and then placed in a precision oven at 50±2°C for 3 to 4 hours to constant weight, taken out, cooled to room temperature, and obtained a physical color block.

Abstract

The invention discloses a combination of 5GY 9 / 3 pigment and a method which uses the combination to prepare object color block; the combination part by weight comprises 995-1005 portions of CSC-A base material, 0.05 portion of PBK7 with the pigment content of 9%, 5.55-5.65 portions of PY138 with the pigment content of 27% and 0.15-0.20 portion of PG7 with the pigment content of 20%. The main composition of CSC-A base material is acrylic copolymer with the content of 30-40%; TiO2 is adopted as the main white pigment with the content of 18-22%; the contrast ratio of the base material is 0.90-0.96; the Stormer viscosity is 90-100 KU; the glossiness is 5-10 degrees when the incident angle is 85 degrees; the combination of the invention has high weatherability, good stability and good ratio reproducibility; the adopted raw material and the process meet the requirement and standard of low VOC and zero VOC; compared with the standard value in the theoretical model in Chinese Color System, the object color block has small chromatic aberration; the color is realized with high accuracy; the manufacturing process is proficient; the object color block has super strong practicality 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...
