Abstract
The present invention is related to an one component self-crosslinking reactive siloxane-terminated polypropylene oxide emulsion and a process for preparing the same. In the inventive process, using a reactive siloxane-terminated polypropylene oxide (SPPO) as raw material and a polyether-modified polysiloxane as protection colloid, a waterborne SPPO emulsion with excellent storage stability and freeze-thaw stability was prepared through phase inversion emulsification in the presence of composite emulsifying agent. And this process has some advantages such as low capital investment for equipment, simple procedure, easy operation and low production cost. And the obtained SPPO emulsion can be used as basic raw materials for the production of environmental friendly waterborne products such as paints, binders, sealing agents etc.
