A kind of anti-dust haze transparent window screen and preparation method thereof

Abstract

The invention relates to a dust-proof and haze-proof transparent window screen and a preparation method thereof. The dust-proof and haze-proof transparent window screen is characterized in that nanoparticles serve as electrostatic repulsion agents, and the window screen is composed of a silk screen framework, an intermediate layer painted on the silk screen framework and a functional layer painted on the intermediate layer; the silk screen framework is a metal silk screen or a synthetic macromolecular material silk screen or a natural macromolecular silk screen which is 100-500 meshes and is used for the commercialized silk-screen printing process or the filtering separation process; the intermediate layer is made of a polyurethane resin film or an organic silicon resin film; the thickness of the intermediate layer is 200-2000 nm; the thickness of the functional layer is 200-2000 nm, and the surface resistance of the functional layer is 10<7>-10<8> ohm; the functional layer is composed of rodlike nano SiO2, antimony-doped nano SnO2, anatase type nano TiO2 and organic silicon resin. According to the dust-proof and haze-proof transparent window screen provided by the invention, the raw materials are low in price and easy to get, the preparation process is simple and convenient, cost is low, and industrialization, application and popularization are facilitated.

Description

technical field [0001] The invention relates to an anti-dust and haze transparent window screen and a preparation method thereof, in particular to a low-cost anti-dust and haze transparent window screen using nanoparticles as an electrostatic repellant and a preparation method thereof, belonging to the fields of energy saving, environmental protection and new materials. Background technique [0002] Fog is an aerosol composed of large numbers of tiny water droplets or ice crystals suspended in the air near the surface. Haze is a solid aerosol formed of tiny particulate matter suspended in the air. Haze is mainly caused by man-made environmental pollution, coupled with natural conditions such as low temperature and wind, which make it difficult for pollutants to diffuse. The haze particle size of PM2.5 is less than 2.5μm, which can directly enter and adhere to the human lower respiratory tract and lung lobes. At the same time, the chemical components in the particles will ca...
