Abstract

La presente invención se refiere a procedimiento mejorado para preparar una composición termofraguable, meldeable por inyeccion, caracterizado porque comprendea alimentar una resina termofraguable de fenol-aldehido y un llenador a un extrusor de gusano; hacer avansar el material a través del extrusor de gusano mientras se somete el mismo a una temperatura elevada, de menos de 143°C, por un tiempo suficiente para fundir la resina de fenol-aldehido; extruir dicho producto fundido a través de un orificio de dado del extrusor; triturar el producto de extrusión a la forma de pastilla de un diámetro de por lo menos 1.59 mm; y mezclar y revestir dichas pastillas con una cantidad de 0.05 a 2 por ciento en peso, con base en el peso de las pastillas, de una sal metálica de un ácido graso de cadena larga de 8 a 20 átomos de carbono.The present invention relates to an improved process for preparing an injection meltable thermosetting composition, characterized in that it comprises feeding a phenol-aldehyde thermosetting resin and a filler to a worm extruder; advancing the material through the worm extruder while subjecting it to an elevated temperature of less than 143 ° C, long enough to melt the phenol-aldehyde resin; extruding said molten product through a die hole in the extruder; grinding the extrusion product into the bar form of a diameter of at least 1.59 mm; and mixing and coating said tablets in an amount of 0.05 to 2 weight percent, based on the weight of the tablets, of a metal salt of a long chain fatty acid of 8 to 20 carbon atoms.
