Abstract
La presente invencion se refiere a un método de emulsificacion continua capaz de emulsificar gomas de organopolisiloxano de alta viscosidad y capaz de realizar una produccion en masa continua. Se utiliza un extrusor compuesto cuyo barril (1) contiene cuando menos dos vástagos equipados con elementos mezcladores(3) instalados en paralelo. En cada vástago hay formadas elevaciones y depresiones a lo largo de la direccion axial, y las elevaciones y depresiones de los respectivos vástagos se intercalan. La goma de organopolisiloxano, el agente emulsificante y agua se suministran de manera continua como materias primas a este extrusor compuesto, produciéndose una emulsion de organopolisiloxano en agua al mezclar y homogenizar las materias primas, sometiéndolas, a través de la rotacion de los vástagos equipados con elementos mezcladores, a una accion de corte a una velocidad de corte de cuando menos 10/segundos (por ejemplo, 10 segundos recíprocos).
