Embodiment 1
[0037] To prepare the organic-inorganic composite emulsion described in this patent, the required raw materials are as follows (parts by mass):
[0038]
[0039] Wherein, the acryloyloxyethyltrimethylammonium chloride is an aqueous mixture, and the content of acryloyloxyethyltrimethylammonium chloride is 78wt%: the methacryloyloxyethyltrimethylammonium chloride Ammonium is an aqueous mixture, and the content of methacryloxyethyltrimethylammonium chloride is 80wt%.
[0040] Concrete preparation method comprises the following steps:
[0041] 1) Drop 30 parts of deionized water and 5 parts of titanium dioxide nanoparticles into a small test reaction kettle made of quartz with 2 commercially available common high-pressure mercury lamps on the outside, and pass Nitrogen gas was used to purge the inside of the reactor.
[0042] 2) After heating up to 45±2°C under stirring, turn on the high-pressure mercury lamp to irradiate from the side of the reactor. After 15 minutes, pump 1...

Embodiment 3
[0055] To prepare the organic-inorganic composite emulsion described in this patent, the required raw materials are as follows (parts by mass):
[0056]
[0057] Wherein, said diallyl dimethyl ammonium chloride is an aqueous mixture, and the content of diallyl dimethyl ammonium chloride is 65 wt%.
[0058] Concrete preparation method comprises the following steps:
[0059] 1) Put 33 parts of deionized water and 15 parts of neutral titanium sol into a reaction kettle equipped with a jacketed water bath device, a stirring device and a feeding device, and an explosion-proof LED ultraviolet lamp for photocuring is installed on the inside of the top cover, and pass into Nitrogen was used to purge the interior of the device.
[0060] 2) After heating up to 45±2°C under stirring, turn on the ultraviolet light source to irradiate above the liquid level in the kettle, and pump 1 part of acrylic acid and 24 parts of methyl methacrylate pre-mixed into the reaction kettle at a constan...
