PROCESS FOR BLENDING LIQUID RUBBER AND CARBON BLACK

摘要

The prevent invention provides in a process for blending liquid rubber and carbon black by stirring and dispersing a mixture of a liquid rubber and carbon black, an improvement which comprises mixing 60-150 parts by weight of carbon black with 100 parts by weight of the liquid rubber to produce a preliminary dispersion of carbon black and liquid rubber diluting the preliminary dispersion with a liquid rubber to produce composition having a required carbon black content. The present invention thus provides a process for blending liquid rubber and carbon black to prepare a composition of carbon black and liquid rubber in which carbon black is substantially uniformly dispersed, by using a simple high torque mixer, in a simple operation.
