【 摘 要 】

CaCO3 and wood pulp were added in base-sheet. And the effects on the permeability, physical properties, smoke index and microstructures were researched. The results indicated that: 1) With the increase of CaCO3 adding rate, wood pulp addition rate was 6%, the bulk thickness and air permeability of base-sheet increased slightly, while the tensile index and tear index of base-sheet decreased gradually. 2) Base-sheet permeability analysed showed that CaCO3 on the surface of base-sheet was conducive to the formation of more pores, the liquid infiltration from the surface of the base-sheet to the interior, the permeability and liquid absorption properties of the base-sheet were improved. 3) Add 50% calcium carbonate, the CO, TPM and deliveries of tar in mainstream smoke of base-sheet decreased by 17.25%, 19.51% and 18.75%, respectively.
