Concrete glue reducing agent and preparation method thereof
The invention discloses a concrete glue reducing agent and a preparation method thereof. The concrete glue reducing agent comprises the following raw materials in parts by weight: 30-50 parts of hydrophobic modified carboxymethyl hydroxyethyl cellulose; 0.05 to 0.1 part of a dispersant; 0.05 to 0.1 part of a penetrant; the substitution degree of carboxymethyl cellulose of the hydrophobic modified carboxymethyl hydroxyethyl cellulose is 0.3 to 0.6, and the substitution degree of hydroxyethyl is 1 to 1.5; the hydrophobic modified carboxymethyl hydroxyethyl cellulose is obtained by carrying out hydrophobic modification on micromolecular carboxymethyl hydroxyethyl cellulose; the molecular weight of the micromolecular carboxymethyl hydroxyethyl cellulose is 2000 to 30000. The concrete glue reducing agent obtained in the invention has good glue reducing rate, can effectively reduce the use amount of concrete raw materials, and can improve the fluidity and compressive strength of concrete.
