Continuous method for the production of powder paint suspensions (powder slurries) and powder paints

摘要

A continuous process for preparing powder slurries and powder coating materials wherein a liquid binder component is prepared by continuous addition polymerization, polycondensation or polyaddition in bulk and then mixed with a liquid starting component and conveyed to a dispersing unit where it is emulsified in a continuously supplied medium. Powder slurry is prepared by cooling the emulsion to form a suspension of dimensionally stable particles directly from the aqueous emulsion or alternatively from the suspension. The resultant powder slurries are used as coating materials or to prepare coating materials, adhesives, and sealing compounds.
