The invention discloses a method for preparing high-viscosity and superfine pseudo boehmite coating adhesive. The method comprises the steps: CO2 gas and a NaAlO2 solution can form adhesive in a bell-jar type rotary filling continuous gas-liquid reactor, the NaAlO2 solution is evenly sprayed down from the upper portion, CO2 gas evenly enters from the lower portion, and is mixed reversely with the NaAlO2 solution and has a chemical reaction with the NaAlO2 solution under the condition of certain temperature and pH; then a reaction product is pressed into a plate-and-frame filter press by a pressing pump after aging certain time in a washing kettle, and is washed for a plurality of times, and the pseudo boehmite coating adhesive (aluminum carbonate adhesive) is obtained; then the adhesive is dried in a drying room and pulverized in a pulverizer. In this manner, the method prepares the high-viscosity and superfine pseudo boehmite coating adhesive with the cheap CO2 gas and NaAlO2 solution as the raw materials, t
