The invention relates to a modified cement grinding aid, belonging to the technical field of cement assistants. The modified cement grinding aid is prepared from the following substances in parts by weight: 20-30 parts of polymerized polyalcohol, 10-30 parts of lignin-based alkylol amine, 2-10 parts of sodium soap, 5-10 parts of polytetrafluoroethylene powder, 1-5 parts of solid aluminum dihydrogen phosphate, 1-4 parts of gelatin and 2-6 parts of sucrose. The particle size of the solid aluminum dihydrogen phosphate is 50-80nm. The modified cement grinding aid is beneficial to highly fine milling and superfine grinding, is beneficial to enhancing the yield of the grinder, and enhances the yield of the ball grinder by 25%. The modified cement grinding aid is beneficial to lowering the grinding energy consumption, enhancing the clinker utilization ratio and saving the cost. The clinker powder in the cement can basically complete the hydration reaction within 20 days, thereby completely displaying the strength action. The modified cement grinding aid is beneficial to improving the production of special cement, and is beneficial to energy saving and emission reduction in cement industry.
