Latex microspheres refer to tiny spherical particles prepared by emulsion polymerization and other methods with latex as the matrix. Monodisperse black latex microspheres refer to the prepared latex microspheres that have a single dispersion and are black.
The method of preparing monodisperse black latex microspheres usually consists of the following steps: first, the black pigment is mixed with the latex and stirred thoroughly;Then, under the condition of stirring, the mixture is slowly added dropwise to the aqueous solution containing the emulsifier, and the emulsion is formed under the action of high-speed stirring;Finally, the resulting emulsion is subjected to heat treatment to complete the preparation of latex microspheres.
In the preparation process, in order to realize the preparation of monodisperse black latex microspheres, it is necessary to control various factors, such as the type and concentration of latex, the type and concentration of black pigment, the stirring speed and time, the type and concentration of emulsifier, etc. In addition, the heat treatment temperature and time also need to be precisely controlled to ensure the stability and performance of the microspheres.
