Abstract

The invention relates to the technical field of window screens, in particular to a preparation method of a window screen coating for air purification. The preparation method comprises steps as follows: (1) materials are prepared; (2) 3-ethyl-3-oxetanemethanol is dissolved in an organic solvent, an initiator, a titanium source, a zinc source and kaolin are added, the mixture is subjected to refluxat 50-60 DEG C for 5-10 h, a precipitator is added for precipitation, a precipitate is dried to the constant weight under the vacuum condition, the temperature is increased to 270-300 DEG C, a productis continuously calcined for 1-3 h, and modified hyperbranched polyether is obtained; (3) the modified hyperbranched polyether in the step (2) and colloidal graphite powder are mixed and dispersed insolvent type thermosetting resin, a diluent and a curing agent are matched, the mixture is stirred at a high speed for 15-20 min, and the window screen coating is obtained. The titanium source and the zinc source are introduced into the forming process of hyperbranched polyether and are converted into titanium oxide and zinc oxide in situ in molecular pore channels of the hyperbranched polyether,organic matters in adsorbed particulate pollutants are rapidly degraded, and air is rapidly purified.

Description

technical field [0001] The invention relates to the technical field of window screens, in particular to a method for preparing a window screen coating for air purification. Background technique [0002] Window screen, also known as screen window, is a mesh structure set on the window to block flying insects without affecting indoor ventilation. With the improvement of people's living standards, people's functional requirements for window screens can no longer just stop at flying insects. [0003] The rapid economic development blindly pursued has led to serious environmental pollution, leading to a decline in air quality, an increase in the content of PM2.5 in the air, and a large number of particulate pollutants such as smoke, dust and floating dust can easily pass through the through holes of the window screen during the process of ventilation Entering the room, thereby seriously affecting the indoor air quality, resulting in ventilation that outweighs the gain. Also the...
