Abstract

The invention belongs to the field of smoke filtering and discloses a smoke filtering material and a preparation method thereof. The smoke filtering material comprises two pieces of melt-blown non-woven fabric with peripheries composited and pressed to be sealed, and electret cotton is arranged in space formed between the two pieces of melt-blown non-woven fabric. The preparation method of the smoke filtering material comprises steps as follows: S1, the two pieces of melt-blown non-woven fabric are stacked; S2, the electret cotton is arranged between the two pieces of melt-blown non-woven fabric; S3, peripheral edges of the two pieces of melt-blown non-woven fabric are composited and pressed to be sealed. The smoke filtering material integrates melt blowing, electret and composition, has the excellent characteristics of high efficiency, high dust capacity and low resistivity and can replace glass fiber filter materials to be widely applied to air purification in the industries of hospitals, firefighting and the like.
