Emery spraying facing base paper

The invention discloses an emery spraying facing base paper. A preparation method of the emery spraying facing base paper comprises the following steps: S1, pulping: putting hardwood pulp into a hydraulic crusher, performing hydraulic decomposition to obtain a wood pulp raw material, and putting the wood pulp raw material into a pulp tank for later use; S2, mixing: putting wood pulp raw materials into a mixing machine, putting kaolin, a defoaming agent and an antioxidant into a pulp tank, and preparing mixed wood pulp; S3, conditioning: adding pure water into the mixed wood pulp for dilution, and adding a wet strength agent after dilution; S4, preparing: dehydrating, drying, calendaring and curling the diluted wood pulp; and S5, spraying: performing transmission spraying of emery on the curled and formed body paper to obtain the emery spraying facing base paper. The emery is continuously sprayed on the formed facing base paper to improve the external strength of the facing base paper, and meanwhile, after the
