Abstract

The invention relates to an anti-haze screen window and a preparing method thereof. The anti-haze screen window is made of high polymer materials, titanium dioxide nanoparticles and screen window materials through an electrostatic spinning method. The high polymer materials are one or more of polyvinylidene fluoride, poly methyl methacrylate, thermoplastic polyurethane, polyacrylonitrile and polyethylene terephthalate. According to the anti-haze screen window, the spinning efficiency is high, nano-fiber membranes are uniform and are in close fitting with the screen window, holes are dense, ventilation and breathability are achieved, the screen window can be anti-haze, anti-dust, anti-pollen and anti-mosquito, PM2.5 particulate matters are be effectively blocked, the PM2.5 filtering efficiency reaches more than 99%, clean air effective circulation indoor and outdoor is maintained, and exhaust gas pollution of automobile tail gas is effectively solved. The preparing method of the anti-haze screen window is simple, raw materials are easy to obtain, the cost is low, and scale production is easy.

Description

technical field [0001] The invention relates to the field of indoor anti-fog and haze, in particular to an anti-fog and haze screen window and a preparation method thereof. Background technique [0002] Recently, global environmental pollution has become a growing human health concern, affecting human visibility, direct and indirect radiative forcing, climate and ecosystems. Among various types of pollution, particulate matter (PM) pollution has attracted great public attention. PM2.5 (aerosol particles with an aerodynamic diameter of less than 2.5 microns) is very harmful because it is particularly prone to penetrate the lungs and bronchi of humans due to the small particle size. Numerous studies have shown that long-term exposure to dangerous PM2.5 particles leads to higher morbidity and mortality. Additionally, PM2.5 has a significant impact on global climate by absorbing and scattering solar radiation and acting as cloud condensation nuclei. [0003] In smoky environm...
