Surface alcoholized calcium oxide as well as preparation method and application thereof

The invention relates to surface alcoholized calcium oxide as well as a preparation method and application thereof, and the core content is as follows: surface alcoholization treatment is carried outon calcium oxide powder by utilizing ethanol at normal temperature, and then excess ethanol is dried out in a drying oven to prepare the surface alcoholized calcium oxide product provided by the invention. The adopted calcium oxide powder is lightly calcined calcium oxide, the CaO content is larger than or equal to 85%, and the specific surface area is 300-600 m < 2 >/kg; the ethanol is industrialanhydrous alcohol; the reaction treatment conditions are as follows: the soaking time in ethanol is 0.25-4h, and then drying is carried out in the drying oven at 50-80 DEG C until the weight is constant. Compared with the prior art, according to the surface alcoholized calcium oxide, the hydration exothermic reaction rate of the calcium oxide powder can be remarkably reduced, the hydration exothermic starting time is rema
