Nano-titanium dioxide, the 30% pre- breast that 120 parts of deionized waters of addition, 8 parts of emulsifiers, 5 parts of surfaces are modified in a kettle
Change liquid, stir 15min, be warming up to 65 DEG C, add in the solution of 0.3 part of initiator sodium peroxydisulfate and 10 parts of water, after reacting 15min,
Remaining pre-emulsion and the solution of 0.5 part of initiator sodium peroxydisulfate and 20 parts of water is added dropwise simultaneously, 3h is dripped off, and is warming up to 75 DEG C,
Insulation reaction 1h is further continued for, is cooled to 50 DEG C hereinafter, nano-titanium dioxide/quaternary ammonium salt, acrylate compound antibacterial breast must be made
Liquid.
