3 results about "Pigment composition" patented technology

The invention discloses a combination which expresses a 2.5P 5.25/5 pigment and a technical method for preparing a color characterization matter by the combination. The compositions in portion by weight of the combination are: 995 to 1005 portions of CSC-B base material, 12.6 to 13.6 portions of PV23 pigment (with the content equal to 30 percent) and 2.2 to 2.3 portions of PBK7 pigment (with the content equal to 9 percent), wherein the essential component of the CSC-B base material is an acrylic acid polymer with the content of between 30 and 40 percent and the average molecular weight ranging from 150,000 to 200,000; TiO2 is selected as main white pigment with the content of between 8 and 12 percent; moreover, the contrast ratio of the base material is between 0.78 and 0.82, while the Stormer viscosity is between 90 and 100KU; and when an incident angle is equal to 85, the glossiness of the base material is between 5 and 10. The color characterization matter has ideal weathering resistance and stability and excellent proportioning reproducibility, and the raw materials and the technological process adopted by the color characterization matter accord with the requirements and the standards of environmental protection for low VOC and zero VOC; moreover, the color characterization matter has less color difference as compared with a standard value in the national standard theoretical model of the Chinese Color System as well as higher accuracy in color realization, and can be widely used in a plurality of color-related fields.

This invention discloses a kind of 7.5P 7.5/4 pigmentary combination and its method for preparation of color blocks. The compositions of the said combination are as follows by weight: CSC-B, the base in 995-1005 portions; PR122 with 30% color content, in 1.97-2.01 portions; PV23 with 30% color content, in 0.09 portions, PBK7 with 9% color content, in 0.28-0.30 portion. The main constituent of the said CSC-B base is acrylic acid copolymer, whose content is 30-40% and the marked ISO 591 R2 pigment, whose content is 8-12%, is the main used white pigment with the content of titanium dioxide greater than or equal 95%, the oil absorption less than or equal 20g/100g and the Reynolds coefficient of the reducing power equal to 1800. The contrast ratio of the main material to the base is 0.78-0.82, the Stomer viscosity is 90-100 KU and the gloss is 5-10 degree at an incidence angle of 85 degree . The said combination in this invention has characteristics of high weather resisting property and stability and good repeatability of the mixture ratio. All used crude materials and technical processes meet the requirements and standards of low voice and zero voice. The chromatic aberration of the said color blocks is small compared to the standard values of the theoretic models in the book 'Chinese Color System'. With the high accuracy of the implemented color, the good proficiency of the making technique, the said product has strong use value.
