Zusammenfassung: | The invention discloses nitrocotton for indoor fireworks and a production process thereof, and relates to the technical field of firework manufacturing, and the production process comprises the following steps: S1, immersing lignocellulose into a mixed acid solution to carry out nitration reaction, after the reaction is finished, carrying out suction filtration by using an eluent, then adding water to carry out extraction and liquid separation, removing a water layer, and retaining an organic layer to obtain a nitrocellulose solution; s2, adding an organic solvent, a stabilizing agent, a desensitizer and a pore-forming agent into the nitrocellulose solution, and gelling in a kneading machine; s3, wet granulation, solid-liquid separation and heating are conducted, and the nitrocotton for the indoor fireworks can be obtained. The bulk density of the nitrocotton for the indoor fireworks prepared by the process is 0.8-1.29 g/cm < 3 >, the water content is 2.1-3.2%, and the ignition point is 185-190 DEG C. The nit |
