▎ 摘　　要

NOVELTY - The rapid and continuous preparation method of high-efficiency and multi-functional air filter material (2) involves: dipping the light-cured resin into a coiled air filter material (1); heating by infrared; softening the filter fiber using the dry powder injection device (6) to blow functional particles (7) to the filter material; then pressing the filter material by the paddler; pressing the functional particles into the fiber, where one part of the functional particles completely enter the fibers and the other part of the functional particles are partially embedded into the fibers; and finally, curing the surface layer of light-cured resin through illumination and cooling, and completely fixing the functional particles on the surface layer of the filter material. USE - Rapid and continuous preparation method of high-efficiency and multi-functional air filter material. ADVANTAGE - The processing method is convenient, efficient, pollution-free, good in fastness and wide in fiber applicability, and can be used by combining different functional particles to finish one-step preparation of the multifunctional air filter material. Most functional particles are positioned on the surface of the fibers, so that the rough surface area of the filter material can be greatly improved through loading of the functional particles, and more adsorption sites are provided for the filter material.
