Carbon Black Masterbatches and Method for Making the Same

摘要

This invention relates to a process for the preparation of rubber carbon black masterbatches containing 70% by weight and above of carbon black. Prevulcanized latex is used as the medium to incorporate the carbon black powder to produce such rubber carbon black masterbatches. Either a small amount of raw latex or a small amount of process oil or both may be mixed with the prevulcanized latex before incorporating the carbon black powder.
