Embodiment 1

[0024] Weigh 13.38 grams of PG7, 0.01 grams of PBK7, 4.66 grams of PB15:3, 34.58 grams of PW6, and 1000 grams of CSC-B base material. Mix the above materials evenly, and then apply the obtained composition on the substrate evenly and evenly by mechanical coating under the conditions of relative humidity of 50%±5% and room temperature of 23±2°C. It is metallic or non-metallic material. The wet film thickness of the coating is 250m, and then placed in a 50±2°C precision oven to dry for 3-4h to constant weight, take it out, cool to room temperature, and obtain the color characterization.

Embodiment 2

[0026] Weigh 13.23 grams of PG7, 0.01 grams of PBK7, 4.66 grams of PB15:3, 34 grams of PW6, and 1000 grams of CSC-C base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a compound which expresses 10BG 5 / 8 pigment and a technical method for preparing a color attribute with the compound. The composition of the compound by the weight portion is as follows: 995 portions to 1005 portions of CSC-C base material, 13.23 portions to 13.53 portions of PG7 with the pigment content of 20 percent, 0.01 portion of PBK7 with the pigment content of 9 percent, 4.66 portions of PB15:3 with the pigment content of 27 percent, and 34 portions to 35.2 portions of PW6 with the pigment content of 65 percent. The main component of the CSC-C base material is acrylic acid multipolymer which accounts for 35 percent to 45 percent. The contrast rate of the base material is 0.20 to 0.40, the stormer viscosity is 90KU to 100KU and the lustrousness is 5 to 10 when the incident angle is 85. The color attribute of the invention has good weather resistance, stability and ratio reproducibility; the used raw materials and the technological process meet the requirements and standards for low-VOC and zero-VOC environment protection; compared with the standard value in the national standard theoretical model of China color system, the color attribute has small color difference, high accuracy in color realization, and can be used in a plurality of color related fields.

Description

【Technical field】 [0001] The present invention relates to a composition, in particular to a composition of pigments, and a technical method for preparing color representations from 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 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 color representation, many important links such as color differ...
