Abstract

The invention discloses a mould-proof repellent mat for files. The mould-proof repellent mat for the files comprises medicinal effective constituents and a carrier, wherein the effective constituents comprise the following components with the content: 10 to 30 percent of pyrethrum extracts, 10 to 20 percent of folium artemisiae argyi extracts, 5 to 10 percent of atractylodes chinensis extracts, 10 to 15 percent of calamus extracts, 5 to 10 percent of wild tobacco extracts, 5 to 10 percent of alum, 5 to 10 percent of turpentine, and 5 to 10 percent of lavender oil; the carrier is adsorption paper with plastic paper attached to two faces or limestone, a plurality of small holes are distributed on the plastic paper, the effective constituents are dropwise added on the adsorption paper so as to be slowly released from the small holes on the surface of the adsorption paper, and the pesticide effect can be prolonged for three months. The mould-proof repellent mat is convenient to use, lasting in pesticide effect, remarkable in effect and small in occupied space, and can be widely used for storing the school files.
