Embodiment 1

[0023] Weigh 0.65 grams of PV23, 0.21 grams of PB15:3, 1.53 grams of PR101, 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.

Abstract

The invention discloses a composition of a 5P 7.5 / 2 pigment, which comprises the following components in parts by weight: 995-1005 parts of CSC-B base material, 0.6-0.7 part of PV23 with the pigment content of 30 percent, 1.48-1.58 parts of PR101 with the pigment content of 65 percent and 0.21 part of PB15:3 with the pigment content of 27 percent. The main component of the CSC-B base material is acrylic copolymer the content of which is 30-40 percent and the average molecular weight range of which is 150,000-200,000. TiO2 is selected as the main white pigment and has the content of 8-12 percent. For the base material, the contrast ratio is 0.78-0.82, the Stormer viscosity is 90-100 KU, and when an incident angle is 85 degrees, the glossiness is 5-10. A color characterization object of theinvention has favorable weather resistance and stability and good proportioning reproducibility; the adopted raw materials and the technology process both meet the low-VOC and zero-VOC environment protection requirement and standard; and compared with a standard value in a theoretical model of Chinese Color System, the color characterization object has little color difference and high accurate degree of color realization, and can be widely applied to many fields correlative 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 15608-1995 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 color representation, many important links such as color d...
