Sludge-proof type polycarboxylate water-reducer and normal temperature preparing method thereof
The invention discloses sludge-proof type polycarboxylate water-reducer and a normal temperature preparing method thereof. The sludge-proof type polycarboxylate water-reducer is formed by copolymerizing unsaturated fatty alcohol-polyoxyethylene ether macromonomers, unsaturated carboxylic acid, positive ion quaternary ammonium salt and quaternary ammonium acrylic ester by the adoption of a free radical solution at the normal temperature and normal pressure. The sludge-proof type polycarboxylate water-reducer can lower the negative effect of clay on concrete effectively, has the advantages of being slowly released, resistant to sludge, good in adaptability and the like and has good dispersion and dispersion maintaining performance on concrete containing different types of sludge.
