Organic silicon/saccharide co-modified polycarboxylate water reducing agent and preparation method thereof
The invention discloses an organic silicon/saccharide co-modified polycarboxylate water reducing agent and a preparation method thereof. The preparation method includes the following steps: (1) preparing a methoxypolyoxyethylene (methyl) acrylate macromonomer; (2) preparing an organic silicon modified (methyl) acrylate macromonomer; (3) preparing a saccharide modified (methyl) acrylate macromonomer; and (4) preparing the organic silicon/saccharide co-modified polycarboxylate water reducing agent with the macromonomers in the steps (1), (2) and (3). The water reducing agent is low in cost, is prepared from environment-protective and recyclable raw materials, is excellent in water reducing performance and slump degree maintaining performance, is simple in preparation method and is suitable for industrial production.
