Preparation method of phthalocyanine colored cement intermediate and phthalocyanine colored cement intermediate

Abstract

The present invention relates to a kind of manufacturing method of phthalocyanine color cement intermediate and phthalocyanine color cement intermediate, in order to solve the problem that phthalocyanine is not easy to disperse in cement, the method is to mix phthalocyanine, white cement, cement dispersant, talcum powder After mixing, add it into a ball mill and grind it. Mixing is to mix phthalocyanine, cement dispersant and talcum powder first, and then add them to white cement for mixing. The phthalocyanine colored cement intermediate is fully mixed with white cement, talc powder accounting for 1-3% of the weight of white cement, phthalocyanine accounting for 1-5% of the weight of white cement, and cement dispersant accounting for 30-100% of the weight of phthalocyanine . The method is to subdivide and blend phthalocyanine and white cement to the greatest extent under the action of additives and ball milling to form a uniform intermediate. The method has the advantages of simple operation, strong operability, low process cost, and can ensure the dispersion degree of phthalocyanine. The intermediate completely overcomes the defect that phthalocyanine is not easy to disperse in cement. When using it, it only needs to be mixed into the concrete material in proportion. When it is applied to concrete, it can achieve the effect of uniform dispersion and long-lasting concrete color, and save a lot of use cost. . It has the advantages of bright color, high coloring rate, good dispersion, good stability and low cost.

Description

technical field [0001] The invention relates to colored cement, in particular to a method for manufacturing a phthalocyanine colored cement intermediate, a method for manufacturing a phthalocyanine colored cement intermediate, and a phthalocyanine colored cement intermediate. Background technique [0002] In the colorful world, blue-green plays an important role and is mostly loved by people. People enjoy the pleasure brought by blue-green from paint, printing, etc., but they are not satisfied. In modern times, colored concrete has been developed, and blue-green is also applied to colored concrete as people explore. [0003] The blue-greens recognized by most people mainly include phthalocyanine, cobalt blue, chrome green and so on. Phthalocyanine has bright color and high coloring rate, but it is difficult to use (it is not easy to disperse uniformly in cement) and has poor weather resistance; cobalt blue is stable, positive in color, and has good weather resistance, but t...

AI Technical Summary

Problems solved by technology

Phthalocyanine has bright color and high coloring rate, but it is difficult to use (it is not easy to disperse uniformly in cement) and has poor weather resistance; cobalt blue is stable, positive in color, and has good weather resistance, but the use cost is extremely high; chrome green is stable and has good weather resistance , but the coloring rate is low, and the cost of use is relatively high
