Embodiment 1

[0023] Weigh 4.61 grams of PV23, 13.21 grams of PR101, 2.6 grams of PBK7, and 1000 grams of CSC-B 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 4.51 grams of PV23, 12.21 grams of PRi01, 2.55 grams of PBK7, and 1000 grams of CSC-B base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Weigh 4.71 grams of PV23, 14.21 grams of PR101, 2.65 grams of PBK7, and 1005 grams of CSC-B base material. Manufacturing process is with embodiment 1.

Abstract

The present invention discloses one kind of 5RP 5.25 / 2 pigment composition and its color lump making process. The 5RP 5.25 / 2 pigment composition consists of CSC-B base material in 995-1005 weight portions; PV23 with pigment content of 30 % in 4.51-4.71 weight portions; PR101 with pigment content of 65 % in 12.21-14.21 weight portions; and PBK7 with pigment content of 9 % in 2.55-2.65 weight portions. The CSC-B base material has acrylic acid copolymer as main component in 30-40 %, and ISO 591 R2 type white pigment with TiO2 content not less than 95 %, oil absorption less than 20g / 100g and reducing power number 1800 in 8-12 %. The base material possesses contrast ratio of 0.78-0.82, viscosity of 90-100 KU, and brightness at incident angle 85 deg of 5-10 deg. The pigment composition has high weather resistance, high stability and high repeatability. The color lump is accurate and practical.

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...
