Abstract
El presente desarrollo se refiere a un proceso para la elaboración de premezclas de caucho natural que comprende estabilizar y concentrar el látex de campo para posteriormente mezclarlo con dispersiones de cargas reforzantes y con emulsiones de aceites de origen mineral o vegetal hasta y opcionalmente otros aditivos, hasta obtener una premezcla de caucho en fase líquida, la que es finalmente pulverizada en un sistema de mezclado, micronizado y secado tipo turbo-rotor para obtener premezclas de caucho en forma particulada. El proceso desarrollado permite obtener premezclas de caucho natural con mejor integración entre el caucho y las cargas reforzantes proporcionando materiales con propiedades mecánicas mejoradas y desempeños superiores en comparación con las premezclas obtenidas mediante procesos convencionales.The present development refers to a process for the preparation of natural rubber premixes that includes stabilizing and concentrating the field latex to subsequently mix it with dispersions of reinforcing fillers and with mineral or vegetable oil emulsions up to and optionally other additives, up to obtain a rubber premix in liquid phase, which is finally pulverized in a turbo-rotor type mixing, micronizing and drying system to obtain rubber premixes in particulate form. The developed process allows obtaining natural rubber premixes with better integration between the rubber and the reinforcing fillers, providing materials with improved mechanical properties and superior performance compared to the premixes obtained through conventional processes.
