摘要： The present invention relates to a pigment dispersion and a black water-reducing agent, more particularly, to a pigment dispersion comprising a carbon black whose surface is modified with an aminosilane compound and a polycarboxylic acid-based water-reducing agent, and a black water-reducing agent using the same. The present invention is characterized in that the surface-modified carbon black with an aminosilane compound is water-dispersed by using a polycarboxylic acid-based water-reducing agent as a dispersing agent having better performance than a naphthanlene-based water-reducing agent. Therefore, the present invention can display black color of the water-reducing agent and cement at the same time and improve the flowability of cement owing to the presence of carbon black in the form of nanoparticles, which enables to manufacture ultrahigh strength concrete. Further, by using the method in accordance with the present invention, it is also possible to use conventional polycarboxylic acid-based water-reducing agents as a pigment dispersing agent for carbon black.

摘要翻译： 本发明涉及一种颜料分散体和黑色减水剂，更具体地说，涉及包含用氨基硅烷化合物和多元羧酸类减水剂改性的炭黑的颜料分散体和黑水 - 还原剂使用它。 本发明的特征在于，具有氨基硅烷化合物的表面改性炭黑通过使用多基于羧酸的减水剂作为分散剂而具有比基于萘醌的减水剂性能更好的分散剂的水分散性。 因此，本发明能够同时显示减水剂和水泥的黑色，并且由于存在纳米颗粒形式的炭黑，从而提高了水泥的流动性，能够制造超高强度混凝土。 此外，通过使用本发明的方法，也可以使用常规的多元羧酸类减水剂作为炭黑的颜料分散剂。
