Abstract

The invention discloses a preparation method for a super-hydrophobic breathable window screen and the super-hydrophobic breathable window screen, and relates to the technical field of building decoration. The method disclosed by the invention comprises the following steps of S1, performing surface pre-treatment on an original window screen to obtain a pre-treated window screen; and S2, performingwater repellency modification on the pre-treated window screen to obtain the super-hydrophobic breathable window screen. According to the preparation method for the super-hydrophobic breathable windowscreen and the super-hydrophobic breathable window screen, the surface of the prepared window screen has a super-hydrophobic function by performing the surface pre-treatment and the water repellencymodification on the original window screen in sequence; water droplets are prevented from penetrating through the window screen by utilizing low surface energy and surface tension so as to realize thefunctions of breathing and ventilating and preventing rainwater from flying indoors; the method disclosed by the invention is simple in process; and the prepared super-hydrophobic breathable window screen has an excellent water repelling effect.

Description

technical field [0001] The invention relates to the technical field of building and home decoration, and more specifically relates to a preparation method of a superhydrophobic breathable window screen and a superhydrophobic breathable window screen. Background technique [0002] In daily life, screen windows often appear as supporting products for doors and windows. Ordinary screen windows are generally composed of window screens and frames for installing window screens. Usually, screen windows are ventilated mosquito nets installed on windows. Its main function is to prevent mosquitoes in summer Ventilate the room and prevent mosquitoes from entering. Although the mesh of the window screen is very small, rainwater will still flow into the room through the window screen in rainy days. Therefore, in rainy days, in order to prevent rainwater from entering the room, people usually close the glass windows outside the screen window. [0003] However, if the glass windows are not...
