    • PROBLEM TO BE SOLVED: To provide a dispersant capable of easily dispersing an insoluble material into a liquid material in a liquid medium and to provide a cement admixture which can enhance the dispersibility of an inorganic material into an aqueous medium, can be used as a pigment dispersant and a cement dispersant and, in particular contributes to the reduction of water and higher fluidity of a cement composition.
      SOLUTION: A structural group (a) originating from vinyl ether, a carboxy-structural group (b) and a nitrogen containing structural group (c) are essential for the dispersant. A polymer (A) having these structural groups at a predetermined ratio enhances the dispersibility of the inorganic material into the aqueous medium, and in particular when applying to the cement composition, enables water saving and is excellent in effect on enhancing the fluidity.

    • 要解决的问题:提供能够容易地将不溶性物质分散在液体介质中的液体材料中的分散剂,并且可以使用能够提高无机材料在水性介质中的分散性的水泥混合物 作为颜料分散剂和水泥分散剂,特别是有助于水的还原和水泥组合物的较高的流动性。 解决方案:来自乙烯基醚,羧基结构基团(b)和含氮结构基团(c)的结构基团(a)对于分散剂是必需的。 具有这些结构基团的聚合物(A)以预定比率提高了无机材料在水性介质中的分散性,特别是当施加到水泥组合物时,能够节水并且对提高流动性具有优异的效果。 版权所有(C)2005,JPO&NCIPI
