Abstract

The invention discloses a preparation method of a composite air filter material, and belongs to the technical field of composite materials. Basalt, vermiculite and the like are used as raw materials,so that the filter material has a self-cleaning effect, and a nano silicon dioxide component can adsorb part of water to wet the surface of the filter material, so that the dispersion effect is improved, and the filter effect can also be well improved. Hard and soft components are combined; nanoparticles are supported, the cross-linking effect between macromolecular colloids is facilitated; hydrogen-bond interaction among the components is used; a gel layer of a nanoscale film is formed on the surface of the filter material; filtration resistance is reduced, according to the present invention,hydrogen-containing silicone oil and allyl methacrylate are adopted as raw materials, so that organic and inorganic components penetrate through each other to form a multi-layer network, and the multi-layer network has characteristics of amphipathy and large internal space so as to easily improve the filtration effect, and the problems of poor filtration effect and high filtration resistance of the existing commonly used air filtration material are solved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of a composite air filter material. Background technique [0002] Filtration is a dynamic process of separating and trapping particulate matter dispersed in gas or liquid. Due to its large inner surface and appropriate voids, the filter material has the ability to capture and adsorb solid particles and separate them from the mixture. Non-woven materials are generally a better choice for filter materials. The main body is a network structure composed of fibers and fibers, and the fibers have curved channels due to bending. At the same time, the intersecting fibers make it have a higher porosity. Materials with different porosities and pore sizes can be obtained through the selection of fiber raw materials, different processing methods and post-finishing, which are ideal methods for preparing filter materials. [0003] In addition to ...
