OLIGOMERES DISPERGIERMITTEL |
摘要 |
<p>A cementitious formulation comprising a cement and an oligomeric dispersant is provided. The dispersant is a reaction product of two or three moieties. The first moiety (A) is a nonpolymeric, functional moiety that adsorbs onto a particle, and wherein one or more A moieties together contain at least two residues to provide attachment of the dispersant onto a particle to be dispersed. The second required moiety (C) is a linear or branched water soluble, nonionic polymer that provides the dispersing capability. A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties. A method is provided for dispersing a cementitious formulation comprising a cement in water, including providing in said cementitious formulation the above oligomeric dispersant. A combination of any cement dispersant with an oligomeric dispersant wherein at least one A moiety is blocked is also provided in a cementitious formulation and in a method of making such cementitious formulation.</p> |
