Problems solved by technology

However, this kind of electrostatic adsorption material does not have long-term effect; when used in an environment with high air humidity, it may also reduce the electrostatic charge, thereby reducing the filtration performance of the filter material, resulting in failure to achieve the design effect
But if you choose a material with higher filtration efficiency, its air resistance will further increase, which will increase the energy consumption of the car

Abstract

The invention relates to a biochemical defense material and application thereof, and belongs to the technical field of safety protection. The invention discloses a biochemical defense material which is composed of a rough filtration protection layer, a filter layer, an activated carbon layer, a spacing layer, an adsorption catalyst layer and a sterilization layer from top to bottom in sequence. The comprehensive filtering efficiency of the material is improved on the premise that the resistance of the material is not affected, and the filtering efficiency for particles with the particle size smaller than 0.3 [mu]m is improved. Meanwhile, the material has the effects of adsorbing gas and sterilizing, finally achieves the purpose of biochemical defense, and can be directly used for preparing an automobile cabin.

Description

technical field [0001] The invention belongs to the technical field of safety protection, and relates to a biochemical defense material and its application. Background technique [0002] Automobile air conditioning filter is a filter specially used for air purification in the car cabin. It is usually combined with electrostatic adsorption materials and activated carbon, which can filter pollen, dust and other particulate matter in the air, and absorb volatile organic compound gases, odor gases, etc. . Ordinary automotive air-conditioning filters only have non-woven fabrics, which can filter large particles with a particle size range of 2.5 μm. Particles of μm have good filtration performance, and have good adsorption performance for VOC, benzene, phenol, ammonia, formaldehyde, xylene, styrene and other gases that are of high concern in automobiles. However, this type of electrostatic adsorption material does not have long-term effectiveness; when used in an environment wit...
