Slag one kind of activating grinding aid and preparation method

The present invention relates to the field of cement production and processing technology, there is provided a slag activated grinding aid composite method for its preparation, composition and ratio of the mass of the grinding aid: water glass 5-10%, 5-10% sodium carbonate , sodium rosin 3-8%, 12-20% betaine liquor, nonionic surfactants 7-12%, 2-10% molasses, 5-10% water soluble polymer and the balance water. A method for the preparation, according to the mass ratio, in turn, water glass, sodium carbonate, betaine mother liquor and non-ionic surfactant is added to water of 40-65 deg.] C, stir; then the addition of sodium rosin, molasses and water-soluble polymers the mixture was stirred uniformly, to obtain a liquid slag activation aids composite product. The present invention not only reduces the cost of production and reduces the harm to the environment, and stable application performance improving aspects improve significant effect in activating co slag cement grinding and physical properties.
