Embodiment 1

[0024] Weigh 0.37 g of PBK7, 18.39 g of PB15:3, 11.13 g of PV23, 1.04 g of PW6, and 1000 g 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.

Abstract

The present invention discloses a combination expressing pigment 10PB 2.5 / 3 and a technical method for preparing for a color representation substance by the combination. The combination consists of 995 to 1005 parts of base material CSC-C, 0.37 part of pigment PBK7 with the content of 9 percent, 11 to 11.25 parts of pigment PV23 with the content of 30 percent, 18.2 to 18.6 portions of pigment PB15:3 with the content of 27 percent and 1.04 portions of pigment PW6 with the content of 65 percent according to parts by weight. The essential component of the base material CSC-C is acrylic copolymer with the content of 35 percent to 45 percent; the contrast ratio of the base material is 0.20 to 0.40; the Stormer viscosity is 90 to 100KU; and when the incidence angle is 85 degrees, the glossiness is 5 to 10. The color representation substance has good weather resistance and stability, and good ratio reproducibility; the raw materials and the technical process meet the environmental protection requirement and standard of low VOC and zero VOC; compared with the standard value of Chinese color system national standard theoretical mode, the color difference of the color representation substance is less, and the accuracy realized by the color is high; and the present invention can be widely applied to a plurality of fields related 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...
