Novel rare earth nano-composite cleaning antibacterial antifogging agent as well as preparation method and application thereof

Abstract

The invention provides a novel rare earth nano composite cleaning antibacterial antifogging agent and a preparation method and application thereof. The novel rare earth nano composite cleaning antibacterial antifogging agent is prepared from, by weight, 0.2-30% of nano rare earth oxide composite dispersion liquid, 0.05-6% of surfactant, 10-25% of solvent, 0.2-5% of lubricant and 0.05-2% of chelating agent, and the balance is a diluent; wherein the nano rare earth oxide composite dispersion liquid is a composite dispersion liquid of nano rare earth oxide and rare earth supported nano titanium dioxide. The novel rare earth nano-composite cleaning antibacterial antifogging agent is remarkable in demisting effect, stable in performance, low in cost, green and non-toxic, and has cleaning and antibacterial functions.

Description

technical field [0001] The invention belongs to the field of antifogging agent preparation, and in particular relates to a novel rare earth nano-composite cleaning antibacterial antifogging agent and its preparation method and application. Background technique [0002] In recent years, with the development of society, transparent substrates such as glass and resin have become indispensable materials in daily life and industrial production, and are widely used in mirrors, lenses, automotive glass, etc. However, when there is a temperature difference between its two sides, when the saturated vapor pressure of moisture on the lower surface is lower than the vapor pressure of the surrounding environment, the water vapor will accumulate on the surface of the object and precipitate into fog in the form of tiny water droplets, thereby affecting vision Effects, such as fogging of glasses in winter, fogging of glasses caused by breathing after wearing a mask, fogging of nurses' goggl...

Problems solved by technology

[0002] In recent years, with the development of society, transparent substrates such as glass and resin have become indispensable materials in daily life and industrial production, and are widely used in mirrors, lenses, automotive glass, etc. However, when there is a temperature difference between its two sides, when the saturated vapor pressure of moisture on the lower surface is lower than the vapor pressure of the surrounding environment, the water vapor will accumulate on the surface of the object and precipitate into fog in the form of tiny water droplets, thereby affecting vision Effects such as fogging of glasses in winter, fogging of glasses caused by breathing after wearing a mask, fogging of nurses' goggles in the fight against the epidemic, fogging of car windows, etc., have caused a lot of inconvenience and affected safety.

[0003] The current anti-fogging agent products have problems such as short anti-fogging time, easy to wipe off the anti-fogging film when exposed to water or inadvertent scratches, and high cost. , cleaning and antibacterial effects are also extremely important, and the current defogger products lack these functions
