Nano glass antifogging agent and preparation method thereof

Abstract

The invention provides a nano glass antifogging agent and a preparation method thereof. The nano glass antifogging agent comprises effective components and water. The effective components comprise an anionic surfactant, a non-ionic surfactant, a nano photocatalytic active substance, an active agent stabilization additive, an organic acid solvent and a volatilization dispersant. In the preparation process, the organic acid solvent and the volatilization dispersant are mixed with partial water so as to obtain solution A; the anionic surfactant is mixed with the non-ionic surfactant so as to obtain solution B; the active agent stabilization additive is added to the solution B, the solution is uniformly mixed, then the solution A is added, and the rest water is added after uniformly mixing, the nano glass antifogging agent is obtained after uniformly mixing. The preparation method is capable of stably dispersing the nano photocatalytic active substance into a carrier solvent, using the super-hydrophilic property and nano adhesiveness thereof, and using own specific ultraviolet shielding and the decomposing and removing of harmful gases in the air as the function extension of the nano glass antifogging agent, and obtaining the nano glass antifogging agent with the long-term stable antifogging effect and the possible functional recovery after long-term use.

Description

technical field [0001] The invention relates to the technical field of antifogging agents, in particular to a nano glass antifogging agent and a preparation method thereof. Background technique [0002] Glass anti-fog products, there are a large number of products on the market now, and the ways of expression are also different, but these products directly use surfactants to form a layer of hydrophilic film on the glass surface to achieve anti-fog effect for a certain period of time. However, this will make it easier for dust to adhere to the glass surface and lose the anti-fog effect faster, and most of the glass anti-fog products cannot continue to maintain the anti-fog effect after contact with water, so the glass anti-fog products on the market are basically All of them have been used and discarded, so the current glass anti-fog products have the following characteristics: 1. The glass needs to be cleaned before use, 2. After use, it can no longer touch water. The patie...

[0002] Glass anti-fog products, there are a large number of products on the market now, and the ways of expression are also different, but these products directly use surfactants to form a layer of hydrophilic film on the glass surface to achieve anti-fog effect for a certain period of time. However, this will make it easier for dust to adhere to the glass surface and lose the anti-fog effect faster, and most of the glass anti-fog products cannot continue to maintain the anti-fog effect after contact with water, so the glass anti-fog products on the market are basically All of them have been used and discarded, so the current glass anti-fog products have the following characteristics: 1. The glass needs to be cleaned before use, 2. After use, it can no longer be exposed to water. The user's body should be corroded and violated. 4. It should not enter the eyes or entrance. 5. The effect of use and product promotion are very different.

[0003] The current research on nano-photocatalytic active substances (such as nano-titanium dioxide) mainly focuses on the preparation of nano-photocatalytic active substances and the destruction and dispersion stability of their agglomeration effects. Due to the impact of nano-coating technology on process conditions, material purity and nanoparticles Constrained by the agglomeration effect, the development is very slow, and the hydrophilicity of nano-materials is only widely used in food, medicine and related textile printing and dyeing industries as active ingredient dispersion carriers, and its hydrophilicity is not used in glass anti-fog. There is too much research and progress in the direction, let alone the industrialization results
