Abstract

UN PROCESO PARA EL RECICLADO DE MATERIALES ELASTOMERICOS CURADOS CON AZUFRE USADOS COMPRENDE MASTICAR DICHOS MATERIALES ELASTOMERICOS A TEMPERATURAS PREFERIBLEMENTE INFERIORES A 50 GRADOS CENTIGRADOS CON UNA NUEVA MEZCLA QUIMICA QUE ES CAPAZ DE ABRIR O DESENLAZAR DE UNA MANERA CONTROLADA LA RED VULCANIZADA DE LOS MATERIALES ELASTOMERICOS. LA NUEVA MEZCLA QUIMICA ES FABRICADA A PARTIR DE LA SAL DE ZINC O DITIOFOSFATOS DE DIALQUILO Y MERCAPTOBENCENOTIAZOL U OTROS ACELERADORES EN LA PROPORCION MOLAR POR EJEMPLO EN EL RANGO 1:1 A 1:12 DISPERSOS EN DIOLES Y EN PRESENCIA DE OXIDO DE ZINC Y ACIDO ESTEARICO. ESTA MEZCLA, PUEDE ESTAR CALIFICADA EL "DESENLACE" CUANDO SE MEZCLA CON GRUMOS DE NEUMATICO U OTROS GRUMOS VULCANIZADOS EN CONCENTRACIONES DE 6 PARTES DE AGLUTINANTE POR 100 PARTES DE GRUMOS DE NEUMATICO SOBRE UN MOLINO QUE DESENLAZA EFICAZMENTE LA RED VULCANIZADA Y HACE QUE EL COMPUESTO ESTE LISTO PARA EL MOLDEO Y LA VULCANIZACION SIN NECESIDAD DE OTROS PRODUCTOS QUIMICOS DE ENTRECRUZAMIENTO.EL PERIODO DE TOTAL DE MOLIDO, QUE OCURRE PREFERIBLEMENTE A TEMPERATURAS INFERIORES A 50 GRADOS CENTIGRADOS, TARDA SOLO DE 7 A 10 MINUTOS. ALTERNATIVAMENTE, EL AGLUTINANTE Y LOS GRUMOS DE NEUMATICO PODRIAN SER PRIMERO MEZCLADOS EN UN ENTREMEZCLADOR Y POSTERIORMENTE MOLIDOS EN UN MOLINO ABIERTO. LOS COMPUESTOS DE CAUCHO RECICLADOS OBTENIDOS REPRESENTAN NIVELES SATISFACTORIOS DE CARACTERISTICAS FISICAS Y DINAMICAS. TALES COMPUESTOS PUEDEN SER USADOS DIRECTAMENTE EN ARTICULOS MOLDEADOS O EN LA MEZCLA CON COMPUESTOS RECIENTES EN NEUMATICOS Y AREAS ASOCIADAS.
