| titleOfInvention | Air filtering material capable of being washed repeatedly and preparation method thereof |
| abstract | The invention discloses an air filtering material capable of being washed repeatedly and a preparation method thereof. Air filter material includes melt-blown fabric, polytetrafluoroethylene filtration membrane and is located melt-blown fabric with compound adhesive between the polytetrafluoroethylene filtration membrane, compound adhesive includes following component: 24-28 parts of ethylene-vinyl acetate copolymer, 17-20 parts of polymethyl methacrylate, 15-18 parts of low-density polyethylene, 9-12 parts of terpene resin, 3-6 parts of paraffin and 2-3.5 parts of dihexyl phthalate. The air filter material provided by the invention does not reduce the composite strength after being washed for many times, and still has higher filtering efficiency and lower air resistance. In addition, the invention also provides a preparation method of the air filtering material, and the preparation method is simple and efficient to operate and easy for automatic production. |
