Abstract

METODO PARA LA PREPARACION DE UNA EMULSION ACUOSA DE SILICONA CONSTITUIDA POR: 100 PARTES EN PESO DE UN POLIDIORGANOSILOXANO BLOQUEADO TERMINALMENTE CON HIDROXIO; DE 1 A 50 PARTES EN PESO DE SILICE, Y DE 0,1 A 1,5 PARTES EN PESO DE UNA SAL ALQUILESTAÑA. COMPRENDE LAS OPERACIONES: EMULSIONAR DIORGANOSILOXANO EMPLEANDO UN AGENTE TENSOACTIVO ANIONICO Y UNA CANTIDAD DE AGUA SUFICIENTE PARA PROPORCIONAR UNA EMULSION CON MAS DEL 40 POR 100 EN PESO DE SOLIDO; AGREGAR A LA EMULSION DE UNA A 150 PARTES EN PESO DE SILICE AMORFA Y DE 0,1 A 1,5 PARTES DE UNA SAL DE ALQUIL ESTAÑO, Y CONTROLAR EL PH DE LA EMULSION RESULTANTE EN UN VALOR SUPERIOR A 9. LA EMULSION DEL POLIDIORGANOSILOXANO BLOQUEADO TERMINALMENTE CON HIDROXILO SE PREPARA POR POLIMERIZACION ANIONICA EN EMULSION DE UN SILOXANO SELECCIONADO ENTRE POLIDIORGANOSILOXANOS CON UNA VISCOSIDAD NO SUPERIOR A 0,2 PA.S A 25 GC.
