Filter material and preparation method thereof, filter device and fresh air system

Abstract

The embodiment of the invention relates to the technical field of air purification, and in particular, relates to a filter material and a preparation method thereof, a filter device and a fresh air system. The filter material comprises a filter material main body, an antibacterial layer and an accelerant layer, the antibacterial layer is arranged on the filter material main body, the antibacteriallayer contains antibacterial metal ions, the accelerant layer is sprayed on the antibacterial layer, and the accelerant layer contains alkaline components. The antibacterial layer and the accelerantlayer are arranged in a layered manner; on one hand, the antibacterial layer and the accelerant layer do not share one solvent system, the chemical reaction between antibacterial metal ions and alkaline components can be reduced, and no precipitation generates, spraying is facilitated, and the antibacterial effect is ensured; on the other hand, the alkaline component located on the outer layer ofthe antibacterial metal ions can decompose grease molecules of bacteria or viruses, so that the antibacterial metal ions can penetrate through cell walls and destroy the activity of cell synthase, cells die due to the fact that the cells lose division and proliferation capacity, and the sterilization and disinfection effects are achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of air purification, in particular to a filter material and a preparation method thereof, a filter device and a fresh air system. Background technique [0002] The filter material is an essential part of the filter device, which can filter harmful gases and tiny particles in the air, thereby purifying the air. It is widely used in central air conditioners, fresh air systems, aseptic operating rooms, and automotive air conditioners. In order to eliminate germs and viruses transmitted through the air and aerosol, an antibacterial agent is usually sprayed on the filter material, so that the filter material has the function of sterilization and disinfection. Wherein, the antibacterial agent includes main antibacterial components and auxiliary promoting components that can promote the sterilization and disinfection of the main antibacterial components. [0003] In the process of realizi...

Problems solved by technology

[0003] In the process of realizing the embodiment of the present invention, the inventors of the present invention found that: at present, the main antibacterial component and the auxiliary promoting component are usually directly configured as a solvent, and then sprayed on the filter material, however, it is easy to cause a chemical reaction, Produce sediment, which is not conducive to spraying, and also affects the antibacterial effect of the filter material
