The invention relates to a preparation method for a composite air filter membrane, and belongs to the technical field of air filter. The method comprises the following steps: loading a layer of a high-molecular polymer nanofibre membrane material on a non-woven cloth material as a filter layer through a processing method of electrostatic spinning, then loading a layer of a breathable support material made from the same material or other materials on the surface of the composite material by virtue of ultrasonic compounding, thus forming the efficient composite air filter membrane, and producing a pleating filter through pleat processing. The efficient composite air filter membrane prepared by the method disclosed by the invention is good in pleating performance, low in air resistance and long in service life, has an excellent PM0.3-PM10 filtrability, and can be used for a respirator material under atrocious weather conditions. According to the method, the low-density nano-membrane provides great particle filterability, and the breathable support material provides rigidity, so that the composite material is easily subjected to the pleat processing.
