Example Embodiment

[0021] Example 1:

[0022] Weigh 0.03 grams of PBK7, 0.25 grams of PV23, and 1000 grams of CSC-A base material by weight. Mix and mix the above-mentioned raw materials uniformly, and then apply the mixed composition to the coated paper evenly and smoothly under the environmental conditions of 50%±5% relative humidity and 23±2°C at room temperature. On the top, the wet film thickness of the coating is 250μm, and then placed in a precision oven at 50±2℃ to dry for 3~4h to constant weight, take it out, and cool to room temperature to obtain the actual color block.

Example Embodiment

[0023] Example 2:

[0024] Weigh 0.03 grams of PBK7, 0.20 grams of PV23, and 995 grams of CSC-A base material by weight. The production process is the same as in Example 1.

Example Embodiment

[0025] Example 3:

[0026] Weigh 0.03 grams of PBK7, 0.30 grams of PV23, and 1005 grams of CSC-A base material by weight. The production process is the same as in Example 1.

Abstract

The invention discloses the composites of 2.5PB 9/2 paint and the method for preparing the object colored block. The composites based on the weight portion component are CSC-A base 995 to 1005; PBK7, paint content of 9 per cent, 0.03; PV23, paint content of 30 per cent, 0.20 to 0.30. The main component of the CSC-A base is the acrylic acid copolymer with content of 30 per cent to 40 per cent and average molecular weight range between 150,000 to 200,000; TiO2 is selected as the main white paint with content of 18 per cent to 22 per cent; the contrast ratio of the base is 0.90 to 0.96; the stormer viscosity is 90KU to 100KU; when the incident angle is 85 degree, the gloss is 5 degree to 10 degree. The composite of the invention has high weather resistance and stability, good repeatability of the mixture ratio and has all the raw materials and technology process conforming to the environment protection requirements and the standards of the low VOC and zero VOC. Compared with the standard value in the theory model of Chinese Color System, the object colored block has less chromatic aberration, high accurate degree of the realization of the color, refined manufacture process and strong utility 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...
