<p>PROBLEM TO BE SOLVED: To easily obtain a filter for forming gas high in flame retardancy by using a flame retardant low in toxicity by incorporating an inorg. Flame retardant in an adhesive in the filter for removing gas having a filter base material and an absorbent stuck to the base material with the adhesive. SOLUTION: The filter for removing gas 3 is formed with the filter base material 1 and the adsorbent 2 stuck to the base material with an adhesive. And a flame retardant is added to the adhesive forming an adhesive layer. The amount of the flame retardant to be added to the adhesive is preferably 10-200 pts.wt. to 100 pts.wt. adhesive. And the particle size of the flame retardant is kept within 0.1-100μm. Moreover, ammonium polyhyosphate is used as the flame retardant. On the other hand, a meshlike body formed with thermoplastic resin or thermoplastic resin elastmer and having three dimensional net structure is especially preferable as the filter base material 1. Acrylic adhesive (especially acrylic emulsion base adhesive) is especially preferable as the adhesive.</p> |
