Preparation method of quaternary ammonium salt type hydrophilic ultraviolet curing resin

[0030] Example 1

[0031] This embodiment relates to a method for preparing a quaternary ammonium salt type hydrophilic ultraviolet curable resin, which specifically includes the following steps:

[0032] Add ethanol (70 g), polymerization inhibitor p-hydroxyanisole (0.14 g), polyetheramine D400 (2.30 g, 5 mmol) and 80% acryloxyethyl trimethyl ammonium chloride aqueous solution (24.2 g, 10 mmol), reacted at room temperature for 1.5 hours, FT-IR could not detect 810 cm- 1 At the absorption peak of the double bond, the first step is complete. Then add ethoxy dipentaerythritol hexaacrylate (EO96mol) (48.02g, 10mmol), heat up to 45℃ and react for 3 hours, FT-IR can not detect 3400-3300cm- 1 At the absorption peak of the secondary amine, the reaction is terminated and a light yellow transparent liquid is obtained. Then, it was precipitated with n-hexane, and then vacuum dried at 50° C. for 12 hours to obtain a quaternary ammonium salt type hydrophilic ultraviolet curable resin with a func

[0034] This embodiment relates to a method for preparing a quaternary ammonium salt type hydrophilic ultraviolet curable resin, which specifically includes the following steps:

[0035] Add ethanol (78g), polymerization inhibitor p-hydroxyanisole (0.16g), polyetheramine D400 (2.30g, 5mmol) and 80% acryloxyethyl trimethyl ammonium chloride aqueous solution (24.2 g, 10 mmol), reacted at room temperature for 1.5 hours, FT-IR could not detect 810 cm- 1 At the absorption peak of the double bond, the first step is complete. Then add ethoxypentaerythritol tetraacrylate (EO120mol) (56.32g, 10mmol), heat up to 45℃ and react for 3 hours, FT-IR can not detect 3400-3300cm- 1 At the absorption peak of the secondary amine, the reaction is terminated and a light yellow transparent liquid is obtained. Then, it was precipitated with n-hexane, and then vacuum dried at 50°C for 12 hours to obtain a quaternary ammonium salt type hydrophilic ultraviolet curable resin with a functional

[0037] This embodiment relates to a method for preparing a quaternary ammonium salt type hydrophilic ultraviolet curable resin, which specifically includes the following steps:

[0038] Add ethanol (70g), polymerization inhibitor p-hydroxyanisole (0.14g), polyetheramine ED-600 (2.64g, 5mmol) into a 250ml four-necked flask equipped with mechanical stirring, thermometer and nitrogen introduction device. ) And 80% acryloxyethyl trimethylammonium chloride aqueous solution (24.2g, 10mmol), reacted at room temperature for 1.5 hours, FT-IR could not detect 810cm- 1 At the absorption peak of the double bond, the first step is complete. Then add ethoxy dipentaerythritol hexaacrylate (EO96mol) (48.02g, 10mmol), heat up to 45℃ and react for 3 hours, FT-IR can not detect 3400-3300cm- 1 At the absorption peak of the secondary amine, the reaction is terminated, and a light yellow transparent liquid is obtained, which is then precipitated with n-hexane, and then vacuum dried at 5
