Summary: | The invention provides a preparation method of an aqueous dispersion of colorized polymer monodisperse nanospheres. The preparation method comprises the following steps: firstly polymer monodisperse nanospheres are dyed by utilizing disperse dyes to obtain a colorized nanosphere polymer, adding nitrilotriacetic acid, ethylenediamine tetraacetic acid or sodium citrate into the dispersion, then regulating the pH value to be 8-9, and dispersing again by utilizing an ultrasonic cell disruptor. According to the preparation method of the aqueous dispersion of colorized polymer monodisperse nanospheres, provided by the invention, the preparation method of the aqueous dispersion of colorized polymer monodisperse nanospheres with the surfaces containing carboxyl is provided on the premise of protecting surface functional groups of colorized polymer nanospheres and not influencing the viscosity and other properties of the solution. |
