Embodiment 1

[0023] Weigh 0.04 grams of PBK7, 1.39 grams of PR112, 4.68 grams of PY42, 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 0.04 grams of PBK7, 1.29 grams of PR112, 4.58 grams of PY42, and 1000 grams of CSC-A base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Weigh 0.04 grams of PBK7, 1.49 grams of PR112, 4.78 grams of PY42, and 1005 grams of CSC-A base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a compound of 5R 8/4 pigments and a method using the compound to prepare a physical color block. According to the weight proportion, the compositions of the compound are: CSC-A basic material 995-1005 portions, PBK7 0.04 portion (9 percent of pigment), PR112 1.29-1.49 portions (40 percent of pigment), and PY42 4.58-4.78 portions (60 percent of pigment). The main composition of the CSC-A basic material is an acrylic copolymer with the content of 30 to 40 percent. TiO2 is selected as the main white pigment with the content of 18 to 22 percent. The contrast ratio of the basic material is between 0.90 and 0.96, the Stormer viscosity is between 90 and 100KU, and the gloss is between 5 and 10 when the incident angle is 85 DEG. The compound of the invention has high weather resistance and stability, and good matching repeatability; the raw materials and the technical process meet the requirement and the standard of low VOC and zero VOC environmental protection; the physical color block has small color difference compared with the standard value in the theoretical model of Chinese Color System, high accuracy degree of color realization, good production process, and extremely strong 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...
