Abstract

The invention provides a nano antifogging paint composition which comprises the following components in percentage by weight: nano silicon dioxide sol, nano titanium dioxide sol or doped nano titanium dioxide sol, polyorganosiloxane, alkylol amine, acrylamide and a film former. The preparation method of the nano antifogging paint composition comprises the following steps: mixing the nano silicon dioxide sol and nano titanium dioxide sol, adding the polyorganosiloxane, alkylol amine, acrylamide and film former at 60-90 DEG C, mixing, and reacting to obtain the nano antifogging paint. Compared with the prior art, the nano antifogging paint is convenient to use, and after a soft cloth soaked with the paint is used for wiping a glass surface, a transparent nano hydrophilic coating can be formed to have favorable antifogging effect; the effective time after one-time wiping can reach 12 hours; and after the antifogging effective time, the nano antifogging paint can be applied again to restore the antifogging effect.

Description

technical field [0001] The invention relates to a nano anti-fog coating composition and a preparation method thereof, belonging to the technical field of functional coatings. Background technique [0002] Glasses, swimming goggles, car windows, bathroom mirrors and other glass products are commonly used in daily life. When the ambient temperature difference is large or the humidity is high, fog will form on the glass surface, making it blurred and affecting sight. , hinder work and study. [0003] The research on super-hydrophilic anti-fog technology began in the 1970s and 1980s, mainly focusing on TiO 2 Photocatalytic technology unfolds. TiO 2 The photocatalyst coating film has photocatalytic decomposition performance under sunlight irradiation, so that the surface of the glass coating has super-hydrophilic anti-fog performance. Introducing inorganic nanomaterials on the glass surface through sol-gel, electrochemistry, redox, template preparation and other methods can i...
