The invention relates to a production method of recycled case board paper. The recycled case board paper comprises a paper body, wherein the paper body sequentially comprises a face layer, a core layer and a bottom layer from top to bottom. The production method sequentially comprises the following steps of face layer
raw material preparation in proportion, first time of pulping, first time of defibrination, core layer and bottom layer preparation in proportion, second time of pulping, second time of defibrination, bottom layer pulp preparation, core layer pulp preparation, mesh forming, squeezing, first time of
drying, aspersive application on the surface, second time of
drying, press-
polishing and rolling and slitting. The production method has the advantages that a paper anti-burst agent is added in mesh forming and increases the contact area with
fiber, more
hydrogen bonds are formed for bonding, the bonding power of the
fiber is improved,
fiber cutinization is retarded, the
folding endurance of the case board paper is improved, it is ensured that no shedding occurs on the surface after the paper is reused for multiple times, accordingly the damage rate of a smokebox is reduced, the one-time cyclic use rate of the smokebox is improved, it is ensured that the strength of paper cartons is not reduced and the cartons are not damaged after the paper is reused for multiple times, and secondary use is not affected.
