Problems solved by technology

There is only a small amount of graphene in the grinding aid, which only exhibits its grinding aid performance as a single existence, and cannot improve the characteristics of the grinding aid itself, and even precipitate after self-agglomeration after standing
In addition, the price of graphene is too high, a large amount of heat energy is consumed in the preparation process, the process is extremely complicated, and it is not very suitable for industrial production processes

Abstract

The invention discloses a nanometer molybdenum disulfide grinding aid. The nanometer molybdenum disulfide grinding aid comprises, by mass, 30-33% of diethanol monoisopropanolamine, 7-8% of triethanolamine, 7-8% of a dispersion of molybdenum disulfide, 11-12% of molasses, 11-12% of polyol, 25-30% of a saturated brine solution and the balance of water. The nanometer molybdenum disulfide is used forpreparation of the grinding aid and can significantly reduce the grinding cost and effectively improve the grinding quality. The grinding aid is non-toxic and environmentally friendly, can absorb ultraviolet light and has significant environmental benefits. Through combination of the solid grinding aid and the liquid grinding aid, the cement grinding aid is in a colloid state. Compared with the existing solid grinding aid, the grinding aid has a better dispersing form and better effects and is suitable for promotion and use.

Description

technical field [0001] The invention belongs to the technical field of concrete production and processing, and in particular relates to a nano-scale molybdenum disulfide grinding aid and a preparation method thereof. Background technique [0002] In recent years, my country's construction industry has developed rapidly. Cement is the most basic material in the construction industry. The problem of excessive energy consumption in the development of the cement industry has also become imminent. In the cement production process, the main reason for the high energy consumption is the low grinding efficiency, so improving the grinding efficiency is one of the most direct and effective ways to solve the above problems. Generally, there are two ways to improve the grinding efficiency: one is to improve the mechanical structure used in grinding to improve the grinding method and process; the other is to add a small amount of grinding aid to effectively improve the grinding efficienc...
