Abstract

The invention provides solvent-free ultraviolet curing quaternary ammonium salt resin and a preparation method thereof. The preparation method comprises the following steps of: firstly carrying out ring-opening reaction on hydroxyalkylamine and alkyl glycidyl ether, then reacting with polyisocyanate and hydroxyl acrylate, and finally reacting with halogenated alkane to obtain the solvent-free ultraviolet curing quaternary ammonium salt resin. Raw materials are cheap and easy to obtain, reaction conditions are mild, no solvent participates in the reaction process, and operation is simple. The quaternary ammonium salt resin has the characteristics of good anti-fog performance and rapid photocuring.

Description

technical field [0001] The invention belongs to the technical field of polymer material synthesis, and in particular relates to a solvent-free ultraviolet light curing quaternary ammonium salt resin and a preparation method thereof. Background technique [0002] When water vapor condenses into liquid droplets on the surface of a transparent solid material, the scattering performance of light on the surface of the material will increase, which will weaken the light directly passing through the surface of the solid material, thereby affecting the use of the transparent solid material. For example, at low temperatures, windows, glasses, various protective glasses, windshields, solar panels and other transparent materials that are closely related to our lives will appear atomized, which affects people's lives and is more likely to endanger people. safety. Therefore, research on anti-fog methods and anti-fog materials is very important. [0003] At present, the anti-fog methods...
