Slump loss resistant type polycarboxylic water reducer and preparation method thereof
The invention discloses a slump loss resistant type polycarboxylic water reducer and a preparation method thereof. The slump loss resistant type polycarboxylic water reducer is characterized in that a structural formula is as follows: FORMULA as shown in the specification, wherein a, b, c and d represent degrees of polymerization, a is equal to 1 to 2, b is equal to 37 to 74, c is equal to 12 to 14, and d is equal to 12 to 24. The slump loss resistant type polycarboxylic water reducer has a comb-shaped structure, and is modified by glucose, and five hydroxide radicals are contained in glucose molecules, so that the water reducer molecules have good affinity on cement, and the cement can obtain relatively good dispersion performance.
