Abstract

The invention discloses a room-temperature cured nanometer self-cleaning antireflection coating solution and a preparation method of the room-temperature cured nanometer self-cleaning antireflection coating solution. The room-temperature cured nanometer self-cleaning antireflection coating solution comprises anatase titanium dioxide, silicon dioxide, tin antimony oxide, a silane coupling agent, asurfactant and a solvent; the preparation method of the room-temperature cured nanometer self-cleaning antireflection coating solution comprises the following steps: fully mixing an anatase titanium dioxide aqueous dispersion liquid with silica ethanol dispersion liquid according to the ratio, adding the surfactant and the silane coupling agent and stirring for 1h; then adding a tin antimony oxidedispersion liquid, and fully stirring to obtain transparent and stable room-temperature cured nanometer self-cleaning antireflection coating solution. The room-temperature cured nanometer self-cleaning antireflection coating solution provided by the invention is low in cost of raw materials, low in operating temperature, simple in equipment, pollution-free and easy in industrial production, and cured at a room temperature and does not need to be sintered at high temperature, thereby being extremely convenient by being taken as a room temperature self-cleaning product, and further has the characteristics of good stability and transparency, and a thin film obtained by pulling has self-cleaning and anti-fogging properties.

Description

technical field [0001] The invention relates to a preparation method of a normal-temperature curing nanometer self-cleaning coating liquid, in particular to a normal-temperature coating solution containing a low-reflection component of nano-silicon dioxide, a self-cleaning component of nano-titanium dioxide and an antistatic component of nano-tin antimony oxide. A method for preparing a cured self-cleaning anti-reflection coating solution. Background technique [0002] Titanium dioxide has received extensive attention due to its good photocatalytic activity, self-cleaning and anti-fog properties, but due to its wide band gap, its utilization rate of sunlight is not high, and its high refractive index makes it transparent. The efficiency is not high, so it is often necessary to add other inorganic compound nanoparticles to modify, but directly added to the titanium dioxide sol, because the nanoparticles have high surface energy and large specific surface area, it is very easy...
