Problems solved by technology

[0005] Unfortunately, these operations often affect the properties of the transparent substrate itself
[0006] Therefore, it is urgent to find an antifogging agent that does not affect the characteristics of the substrate itself, is easy to operate, has a good effect on suppressing fog formation, and has high hardness and wear resistance, and can provide strong protection for transparent substrates. This anti-fogging agent can perfectly meet the needs of the market and change the current situation that the current transparent substrates are seriously fogged and affect people's production and life.

Abstract

The invention relates to a UV photocuring anti-fogging agent and a preparation method thereof, belongs to the chemical technical field, and provides the UV photocuring anti-fogging agent and the preparation method. The UV photocuring anti-fogging agent is prepared from nano particles, a solvent, a modifier, hydrophilic photocuring resin, hydrophilic photocuring monomer, a photoinitiator, a flattening agent and a dispersing agent. The anti-fogging agent prepared by the preparation method does not affect characteristics of a base material, is good in effect of inhibiting fog forming, has relatively high hardness and wear resistance, and provides powerful protection the transparent substrate. Meanwhile, the anti-fogging agent is simple and convenient in operation.

Description

Technical field [0001] The invention relates to a UV light curing antifogging agent and a preparation method thereof, and belongs to the technical field of chemistry. Background technique [0002] Transparent substrates such as silicate glass, polycarbonate, polyethylene, etc. are widely used in our daily life and production, such as mirrors, face masks, automobile glass, etc., their existence has greatly brought to our life and production The convenience. [0003] However, under the temperature difference environment, the fogging and atomization of transparent substrates such as silicate glass, polycarbonate, polyethylene, etc. seriously affect its light transmittance, causing many inconveniences to daily production and life, such as: glasses Fogging, car windshield fogging, etc. [0004] In response to this kind of phenomenon, the conventional methods currently used mainly include increasing the surface temperature of the substrate (above the water vapor dew point) by external me...
