Abstract

The invention discloses a degradable interlayer material for a screen window capable of purifying air, belonging to the field of air purification. The degradable interlayer material mainly consists of two supporting layers and an electrostatic spinning non-woven fabric, wherein the electrostatic spinning non-woven fabric is placed between the two supporting layers. An ultrathin nanofiber filter layer is prepared by an electrostatic spinning method, and a MnO2 catalyst, an aromatic agent, fluorescent powder and the like are added into the layer. The fiber diameter ranges from 500nm to 5 microns, the aperture ranges from 300nm to 30 microns, the thickness ranges from 20 microns to 2mm, and the porosity is greater than 75%. The ultrathin nanofiber filter layer can filter PM2.5 and decompose toxic matters, and the prepared filter material is integrated with the existing screen window, so that the degradable interlayer material is suitable for various occasions. According to the degradable interlayer material for the screen window capable of purifying air disclosed by the invention, functional assistants can be added according to demand, and the prepared filter material can be further used as a filter membrane for an air conditioner or other filter equipment, and the material is efficient and convenient.

Description

technical field [0001] The invention relates to an interlayer for screen windows capable of air purification and mosquito prevention, especially suitable for filtering PM2.5 particles, and belongs to the field of air purification. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. The harm of fine particles to the human body has been confirmed. After the fine particles are inhaled into the human body, they will directly enter the bronchi, interfere with the gas exchange in the lungs, and cause diseases including asthma, bronchitis and cardiovascular disease. In recent years, air pollution has worsened. In 2013, the national average number of smog days was the highest in 52 years, seriously affecting people's lives. [0003] The pollution components in the air mainly include suspended dust particles and well-known harmful chemical gase...
