Preparation method of dispersive aluminum oxide for castable and castable
The invention discloses a preparation method of dispersive aluminum oxide for a castable. The method comprises the following steps: mixing aluminum oxide powder, a water reducing agent and a thickening time control agent to obtain the dispersive aluminum oxide, wherein the granularity of the aluminum oxide powder simultaneously meet the following formula requirements: D50 is smaller than or equal to 10 micrometers and D90 is smaller than or equal to 20 micrometers. The dispersive aluminum oxide is prepared from the following constituents in parts by weight: 60-95 parts of the aluminum oxide powder, 5-40 parts of the water reducing agent and 0-5 parts of the thickening time control agent. The preparation method provided by the invention is simple in technology and low in cost; the prepared dispersive aluminum oxide can uniformly disperse in the castable; the additive quantity of water in the castable can be obviously reduced; the coagulation performance of the castable can be effectively regulated; the constructability, anti-bleeding property and early strength of the castable are improved.
