The invention discloses a production method and
system for
flame-retardant self-permeable tipping base paper used for cigarettes. The production method comprises the following steps: S100, beating: beating needle pulp by a double-disc refiner with a beating concentration being 65-750 SR and
wet weight being 7-9 g, defibering
eucalyptus pulp by the double-disc refiner with a pulping concentration being 15-200 SR and
wet weight being 1-2 g, mixing the treated needle pulp and
eucalyptus pulp according to a weight ratio of (30-35%): (65-70%) to prepare combined pulp, and adding
calcium carbonate accounting for 30-50% of the total weight of the combined pulp and a
wet strength agent accounting for 1-1.4% of the total weight of the combined pulp into the combined pulp to prepare a mixed pulpingliquid; S200,
papermaking: carrying out
papermaking and forming with a vat
machine to form uniformly interlaced natural pores; S300,
drying: carrying out
drying in a plurality of groups of
drying cylinders, and carrying out
coating with a composite mixture of oxidized
starch and
acrylic resin via a surface
sizing agent applying
machine during drying to treat the surface performance of a
paper sheet; S400, calendaring: finishing the surface of dried paper via a soft calendaring
machine; and S500, printing: printing a
flame retardant on the reverse side of the paper by using a
photogravure press. With the production method and
system for the
flame-retardant self-permeable tipping base paper, the prepared tipping base paper has both high air permeability and flame retardant properties, wherein an air permeability variable coefficient is smaller than or equal to 7%, and the rate of automatic extinguishing reaches 100%.
