High-adaptability anti-mud slump-retaining polycarboxylate superplasticizer and preparation method thereof
The invention discloses a high-adaptability anti-mud slump-retaining polycarboxylate superplasticizer and a preparation method thereof. The high-adaptability anti-mud slump-retaining polycarboxylate superplasticizer is prepared from the following raw materials in percentage by mass: 65-75% of a base material, 5-15% of a material A, 5-15% of a material B and the balance of water, the backing material is prepared by reacting the following raw materials in percentage by mass: 30-50% of a hexa-carbon polyether monomer, 0.1-0.5% of sodium hydroxide, 0.3-0.5% of hydrogen peroxide, 0.5-1.0% of ascorbic acid, 0.1-0.3% of a catalyst and the balance of water; the material A is prepared by reacting the following raw materials in percentage by mass: 35-50% of functional monomer, 10-20% of acrylic acid and the balance of water; the material B is prepared by reacting the following raw materials in percentage by mass: 1-5% of a chain transfer agent, 0.5-2% of a reducing agent and the balance of water. The anti-mud slump-retaining type polycarboxylic acid water reducer is simple in synthesis process, free of heat sources, free of pollution, short in reaction time and high in production efficiency, and the prepared anti-mud slump-retaining type polycarboxylic acid water reducer has excellent anti-mud performance, good adaptability and high dispersity.
