The invention provides an environment-friendly production process of non-woven fabric for air filtration, which belongs to the technical field of air filtration. Polypropylene, electret masterbatch and polymer electret are evenly mixed, and the prepared mixture is fed into a screw for extrusion. machine, the screw extruder is melted and extruded to form a melt, and the melt is sprayed out through a spinneret to form fibers, and the fibers are drawn by hot air at constant temperature and pressure to form melt-blown cloth on the mesh curtain, and then sequentially After infrared radiation heat treatment, high-pressure electret treatment and cooling treatment, the air filter non-woven fabric is wound up, and the electret masterbatch is composed of polypropylene, few-layer graphene nanosheets, antioxidant, compatibilizer, nucleating The composition of the agent; the few-layer graphene nanosheets are prepared by chemical vapor deposition with magnesium oxide microcrystals with a face-centered cubic structure as a substrate and a template, and the electret masterbatch improves the degree of electretization of the fiber, At the same time, the storage stability of the charge is improved, thereby improving the filtration performance.
