NOVELTY - Preparing cellulose functional slurry comprises (1) mixing N-Methylmorpholine N-oxide (NMMO) aqueous solution and functional additive with mass ratio of NMMO and water of 50: 50-75: 25 to obtain functional additive dispersion, (2) mixing the functional additive dispersion with cellulose pulp with polymerization degree of 100-300 to obtain the cellulose functional mixed solution, (3) dehydrating the cellulose functional mixed solution, dissolving cellulose to obtain the cellulose functional slurry, dispersing in the cellulose functional slurry grain diameter of the functional additive is 50 nm to 5.0 mu m. USE - The method is useful for preparing cellulose functional slurry. ADVANTAGE - The method has low melting point; low viscosity; realizes the target of uniformly dispersing the functional additive and cellulose by dehydrating the cellulose, and uses a certain viscosity of the cellulose solution to prevent sedimentation of the functional additive.
