Limestone-cement liquid grinding aid and preparation method thereof
A disclosed limestone-cement liquid grinding aid comprises the following raw materials in percent by mass: 10-15% of polymerized polyol, 10-15% of triisopropanolamine, 10-15% of sodium hexametaphosphate, 5-10% of sodium sulfamate, and the balance water. By using polymerized polyol for replacing triethanolamine with relatively high price, the cement early-stage strength is substantially excited, the grinding efficiency of a grinding machine is improved, and the unit-hour output of the grinding machine is improved. Because of the contained triisopropanolamine, the cement late-stage strength is substantially increased. Sodium hexametaphosphate possesses relatively good dispersing effect, and thus the material grinding easiness is improved. Sodium sulfamate is capable of improving the cement workability and improving cement fluidity.
