Low-basis-weight corrugated paper and preparation process thereof

According to the low-basis-weight corrugated paper and the preparation process thereof, gelatin and N-acetylated chitosan are arranged in a staggered manner to form a framework structure of an integral corrugated paper product, so that the interaction force and the chemical stability of raw materials in the corrugated paper are enhanced, and the mechanical property of the low-basis-weight corrugated paper is remarkably improved; besides, the recovered heat energy enters the soda boiling, steaming and drying procedures through the heat exchanger for heat coupling, so that the energy consumption of slurry heating can be reduced, the production efficiency can be improved, and the production cost can be reduced. The low-basis-weight corrugated paper is prepared from wood pulp, waste paper pulp, calcium carbonate, xanthan gum, a starch solution, gelatin, N-acetylated chitosan, a cross-linking agent and an auxiliary agent. The preparation process comprises the following steps: 1) pulping; (2) ...
