Embodiment 1

[0022] Weigh 1.1 grams of PBK7, 2.61 grams of PR254, 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 2.5RP 7 / 12 paints and a method that uses the combination to prepare real substance color block. The combination has the components with certain weight portions: CSC-A substrate of 995-1005 portions, PBK7 paint of 1.05-1.15 portions and 9 percent and PR254 paint of 2.51-2.71 portions and 30 percent. Main component of the CSC-A substrate is acrylic copolymer with content of 30-40 percent and average molecular weight range of 150,000-200,000. TiO2 is selected as the main white paint with content of 18-22 percent. The contrast ratio of the substrate is 0.90-0.96, the Stormer viscosity is 90-100KU and when the incident angle is 85 degrees, the gloss is 5-10 degrees. The combination of the invention has high weather resistance and stability, good proportion reproducibility and raw materials and technique thereof meet environmental protection requirement and standard of low VOC and no VOC; the real substance color block has little color difference from the standard value specified in theoretical mold in the Chinese Color System, has high accuracy of real color, delicate manufacturing technique 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...
