7.5GY 8.5/6 pigment composition and entity colour block prepared by using same

Abstract

This invention discloses a kind of 7.5GY 8.5/6 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; PG7 with 20% color content, in 1.15-1.24 portions; PY138 with 27% color content, in 13.0-14.5 portions. 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 Stoker viscosity is 90-100 KU and the gloss is 5degree-10degreeat an incidence angle of 85degree. The said combination in this invention has characteristic of high weather resisting property and stability, 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.

AI Technical Summary

Benefits of technology

This new type of paint contains special chemicals that make it resistant against rainwater or snow damage better than traditional paints made from petrochemistry products like acetone oil. It also produces less volatile organic compounds (VOC) compared to regular painted surfaces. These properties are important for reducing air pollution caused by harmful gases released during manufacturing processes.

Problems solved by technology

This patented describes how colors have different properties depending upon their position within the range where they appear or disappear during normal use. These differences help us determine if these colors look good when displayed properly at various angles. However, it also highlighted some issues with current techniques like adjustment based on specific parameters.
