Enhanced type cement composite grinding aid

The invention discloses an enhanced type cement composite grinding aid. The enhanced type cement composite grinding aid is prepared from the following materials in parts by weight: 48-88 parts of diethanol isopropanolamine, 5-28 parts of molasses, 5-22 parts of lignosulfonate, 0-15 parts of inorganic dispersing materials and 5-35 parts of water. The enhanced type cement composite grinding aid disclosed by the invention has beneficial effects as follows: the enhanced type cement composite grinding aid has characteristics of being scientific and practical, overcomes dependency of the cement grinding aid on triethanolamine and triisopropanolamine, has enhancing performances better than those of products which take the triethanolamine or the triisopropanolamine as the main material, satisfies needs of a cement plant on improving early-stage and later-stage strength of the cement, has remarkable economic and social benefits; and meanwhile, the enhanced type cement composite grinding aid disclosed by the invention is properly mixed with components such as the lignosulfonate, the molasses, sodium hexametaphosphate or sodium polyphosphate, and the like, so that comprehensive performances of the product are effectively perfected; and the materials are combined for use, so that the product performances can satisfy different requirements, and popularization value is wide.
