Embodiment 1
[0037] Such as figure 1 and 2 As shown, the tipping paper for preventing liquid leakage described in this embodiment includes a tipping paper base paper 1, and a layer of anti-seepage coating 2 is coated on the inner surface of the tipping paper base paper 1. The seepage coating 2 is a labyrinth anti-seepage structure formed by filling the resin with overlapping tiny scale-like hard foils 21; An axial anti-seepage strip 3, said axial anti-seepage strip 3 is an inverted trapezoidal long strip with a water-absorbing porous structure. In order to increase the proportion of outside air entering the filter rod to adjust the suction resistance, a row of small holes 4 are uniformly arranged at 2.5-3.0 mm from left to right on the tipping paper base paper 1 . The specific preparation steps of the tipping paper for preventing liquid leakage are:
[0038] (1) Ordinary tipping paper is used as the tipping paper base paper 1, and the resin filled with tiny scaly hard foils 21 is evenly...
Embodiment 2
