[0026] The preparation method of the complex is:
[0027] (1) Put N-methylimidazole and brominated n-butane into the reactor at a mass ratio of 4-6:1-3, use nitrogen protection, preheat at 50-55°C for 30 minutes, and add N-methylimidazole 1-2% catalyst by mass, heated to 105-110°C, stirred for 4-6 hours;
[0028] (2) After the stirring reaction is completed, cool down, and place at -2 to 0°C for 2 hours, filter, collect the filter residue, and take 200 to 300 parts of acetone, 40 to 50 parts of the filter residue, 50 to 60 parts by weight 1 part mixed monomer, 4-6 parts initiator, put into the reaction kettle, heat and stir for 3h;
[0029] (3) After heating and stirring, cool to room temperature, discharge, rotary evaporate, remove acetone, collect the residue, put the residue, isopropyl palmitate, and nano-titanium dioxide in a mass ratio of 17-19:4:0.3 In the reaction kettle, under nitrogen protection, stir and react for 5 hours at 210-215°C, then add an additive with 40-...
