Abstract

La presente invención se refiere a una emulsión acuosade organopolisiloxano que comprende (1) de 1 a 70 por ciento por peso de una goma de organopolisiloxano que contiene hidroxilo, que tiene un valor de plasticidad de 50 a 100 basado en el peso de la emulsión de organopolisiloxano; (2) de 0.5 a 25 por ciento por peso de un fluído de organohidrógenopolisiloxano que tiene una viscosidad de 5 a 100 mPa.s a 25 grados C, y un promedio de cuando menos 2 átomos de hidrógeno Si-enlazados por molécula, basado en el peso de la emulsión de organopolisiloxano; (3) de 0.05 a 40 por ciento por peso de un lubricante que tiene un punto de fusión de 25 a 80ºC, basado en la emulsión de organopolisiloxano; (4) de 0.5 a 25 por ciento por peso de mica, basado en el peso de la emulsión de organopolisiloxano; (5) de 2 a 12 por ciento por peso de un agente espesador, basado en el peso de la emulsión de organopolisiloxano; (6) de 4 a 10 por ciento por peso de un surfactante, basado en el peso de la emulsión de organopolisiloxano; y (7) de 15 a 60 por ciento por peso de agua, basado en el peso de la emulsión de organopolisiloxano.The present invention relates to an aqueous organopolysiloxane emulsion comprising (1) from 1 to 70 percent by weight of a hydroxyl-containing organopolysiloxane gum, having a plasticity value of 50 to 100 based on the weight of the emulsion of organopolysiloxane; (2) 0.5 to 25 percent by weight of an organohydrogenpolysiloxane fluid having a viscosity of 5 to 100 mPa.s at 25 degrees C, and an average of at least 2 Si-bonded hydrogen atoms per molecule, based on the weight of the organopolysiloxane emulsion; (3) 0.05 to 40 percent by weight of a lubricant having a melting point of 25 to 80 ° C, based on the emulsion of organopolysiloxane; (4) 0.5 to 25 percent by weight of mica, based on the weight of the organopolysiloxane emulsion; (5) 2 to 12 percent by weight of a thickening agent, based on the weight of the organopolysiloxane emulsion; (6) 4 to 10 percent by weight of a surfactant, based on the weight of the organopolysiloxane emulsion; and (7) 15 to 60 percent by weight of water, based on the weight of the organopolysiloxane emulsion.
