Embodiment 1

[0023] Weigh 0.01 g of PBK7, 0.11 g of PV23, 0.08 g of PB15:3, and 1000 g of CSC-A base material. Mix the above raw materials, and then apply the mixed composition evenly and evenly on the coated paper under the environmental conditions of relative humidity of 50%±5% and room temperature of 23±2°C. The wet film thickness of the coating is 250 μm, and then placed in a precision oven at 50±2°C for 3 to 4 hours to constant weight, taken out, cooled to room temperature, and obtained a physical color block.

Embodiment 2

[0025] Weigh 0.01 g of PBK7, 0.09 g of PV23, 0.07 g of PB15:3, and 1000 g of CSC-A base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Weigh 0.01 g of PBK7, 0.12 g of PV23, 0.09 g of PB15:3, and 1005 g of CSC-A base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a 2.5PB 9 / 2 paint composite and a method to prepare real color-block with the composite. The composite has the constituents (calculated by weight portion) of CSC-A base (995-1,005 portions); PBK7, pigment content 9 percent (0.01 portion); PV23, pigment content 30 percent (0.09-0.13 portion); PB15:3, pigment content 27 percent (0.07-0.09 portion). The main constituent of CSC-A base is acrylic-acid copolymers, content 30-40 percent. TiO2 is adopted as primary Chinese white, content 18-22 percent. The contrast ratio of the base is 0.90-0.96, Stormer viscosity 90-100KU, incident angle 85 degrees, glossiness 5-10 degrees. The composite has sound weatherability and stability and excellent proportioning recurrence, and the applied raw materials and technical process meet the requirements of environment-protection and the standard of low VOC and zero VOC; the real color-block has very small chromatic aberration from the standard value of theoretical model of Chinese Color System, the accuracy of color is relatively high and the production process is simple and efficient. Therefore, the invention has great use 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...
