Abstract

The invention discloses an air filtering material, comprising a base, an oleophilic layer and a hydrophilic layer arranged between the base and the oleophilic layer; the base, the oleophilic layer and the hydrophilic layer are combined by means of needling or spun-lacing; the pore size of the oleophilic layer is not less than that of the hydrophilic layer, the intake side of the base is provided with a hydrophobic layer, and the hydrophobic layer is made from one or any of polyester fiber, polyamide fiber, spandex fiber, polypropylene fiber, polyvinyl chloride fiber and acrylic fiber. The oleophilic layer is made from an oil-absorbing material and an oleophobic material; the hydrophilic layer is made from a water-absorbing material and a hydrophobic material. The air filtering material has the advantages of good structural stability, long service life and reusability, and may still have high filtering efficiency after multiple uses.

Description

technical field [0001] The invention belongs to the technical field of filtration, and in particular relates to an air filter material. Background technique [0002] Air filter materials are commonly used in air purification systems such as air circulation systems and internal combustion engine air filters. With the rapid development of modern industry, the requirements for the cleanliness of the environment are getting higher and higher. In order to achieve a high level of air cleanliness, the requirements for the filtration performance of the selected filter materials are also getting higher and higher. In order to meet the filtration requirements and meet the environmental protection standards, some reusable composite filter materials have emerged. When these filter materials are used together with water or viscous oil, water or viscous oil is used to absorb water-soluble gas or oil-soluble gas, and can also absorb tiny dust, so as to achieve the purpose of enhancing the...
