Preparation method of self-crosslinking microemulsion with high solid content

The present invention provides a method of preparing a high solids content self-crosslinking microemulsion, comprising a shell pre-emulsion was prepared, the preparation of seed emulsion, the polymerization reaction step and incubated specific reactions. The present invention is by using a variety of emulsifiers during the emulsion polymerization, an initiator and an acrylate functional monomer, stabilized and efficient self-crosslinking reaction, thereby obtaining a high solids content, high stability of the microemulsion.
