Embodiment 1
[0013] Modification of nano-titanium dioxide: in parts by weight, take 12g of nano-titanium dioxide, disperse it in toluene, then add 7g of silane coupling agent KH550, then raise the temperature to 100°C at a rate of 10°C / min, and stir for 1h. The surface-modified nano titanium dioxide powder is obtained through centrifugation, washing and drying.
[0014] Preparation of composite resin: in parts by weight, take 8 parts of glutaric acid, 10 parts of styrene, 10 parts of n-butyl methacrylate, and 10 parts of methyl methacrylate, add them to the reactor in turn, and then add OP- 2 parts of 13, 2 parts of TX-13, 15 parts of surface-modified nano-titanium dioxide powder, after stirring evenly, add 1 part of sodium persulfate, heat up to 80 °C at a rate of 10 °C / min, stir for 20 minutes, and then add over 1 part of sodium sulfate, after heating up to 90°C, stir and react for 2 hours, then add 5 parts of glutaric acid, 5 parts of styrene, 5 parts of n-butyl methacrylate, 5 parts of...
