Embodiment 1

[0023] Weigh 10.1 grams of PO73, 9.09 grams of PY42, 11.5 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

[0025] Weigh 10.21 grams of PO73, 9.09 grams of PY42, 11.63 grams of PW6, and 1000 grams of CSC-C base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Take by weight 10.3 grams of PO73, 9.09 grams of PY42, 11.76 grams of PW6, and 1005 grams of CSC-C base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a composition expressing a 10R 6.5 / 12 pigment and a technical method for preparing a color appearance substance by utilizing the composition. The composition consists of the following components according to parts by weight: 995 portions to 1005 portions of CSC-C base materials, 10.1 portions to 10.3 portions of PO73 with the pigment content of 30 percent, 9.09 portions of PY42 with the pigment content of 60 percent, and 11.5 portions to 11.76 portions of PW6 with the pigment content of 65 percent. The main component of the CSC-C base materials is acrylic copolymer, the content is 35 to 45 percent, the contrast ratio of the base materials is 0.20 to 0.40, the Stormer viscosity is 90KU to 100KU and the glossiness is 5 to 10 when the incident angle is 85 degrees. The color appearance substance has excellent weatherability and stability and good ratio reproducibility, and the used raw materials and the technique process conform with the requirements and standards of low VOC and zero VOC environmental protection; compared with the standard value of the National Standard Theoretical Model of Chinese Color System, the color appearance substance has small color difference and high accuracy of color realization and therefore can be widely applied in various fields relevant to color.

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...
