| Abstract:In this paper,melamine formaldehyde resin(MF) fiber and plant fiber were used to prepare air filter base paper, and then strengthened by phosphorus-containing poly-acrylate emulsion(PPAE) to obtain flame retardant air filter paper with washable property. Effects of MF fiber content on the comprehensive performances and flame retardancy of the air filter paper were studied. The experimental results showed that the air filter base paper obtained by MF fiber and plant fiber presented excellent uniformity. The thickness, air permeability and pore diameter of the baser paper increased as the MF fiber content increased, while the bursting strength and tensile strength decreased slightly. The mechanical strength of the flame retardant air filter paper was greatly enhanced after strengthened by PPAE, while other performances showed the same trend as the air filter base paper. When the MF fiber content was 30%, the PPAE reinforced flame retardant air filter paper could pass the GB/T 14656—2009 combustion test and the carbonization length of flame retardant air filter paper was only 8.3 cm， the flame retardant air filter paper had excellent water-rinse resistance, the carbonization length was 11.2 cm after washing. |
