NOVELTY - Grinding aid comprises 10-50 pts. wt. alcoholamine compounds, 5-25 pts. wt. organic diamines, 5-25 pts. wt. triethanolamine derivatives, 1-20 pts. wt. auxiliary agent, 1-8 pts. wt. molasses, 1-10 pts. wt. polyol, 1-3 pts. wt. sodium chloride, 1-5 pts. wt. dispersant, and 40-100 pts. wt. deionized water. USE - The grinding aid is useful for high-strength P-I, P-II cement. ADVANTAGE - The grinding aid agent has good grinding aid effect, and effectively improves the cement 3 days and 28 days of compression strength, so as to fill the gap in the existing technology. The combined action of the nano-fine powder and the carbon fiber forms a linear support structure with very high strength strength, after the cement grinding agent is added to the cement and stirred, the structure of the linear support structures is effectively added to cured cement to enhance the early and compression strength period, and can fully exert the related advantages and synergistic effect of the carbon fiber and the nano sized fine powder. The agent improves wear resistance and heat resistance of the P-I, P-II cement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the grinding aid agent.
