COLORED CEMENT-BASED FORMING MATERIAL AND COLORED CEMENT-BASED FORMED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a colored cement-based forming material capable of producing a colored cement-based formed article colored without coating and hardly taking on brown color even in being exposed out of doors through a long period.;SOLUTION: A W/O type emulsion composition is prepared by mixing and stirring a vinyl monomer, water, a reverse emulsifier and carbon black. The colored cement-based forming material comprising a cement-containing W/O type emulsion composition is obtained by mixing the W/O type emulsion composition with cement. As a result, the carbon black is taken into the vinyl polymer in the W/O type emulsion composition and the colored cement-based formed article is produced to be colored without applying coating. The carbon black is taken and fixed in a polymer formed by the polymerization of the vinyl monomer in the colored cement-based formed article.;COPYRIGHT: (C)2006,JPO&NCIPI
