Problems solved by technology

[0002] Most of the existing black masterbatches with high carbon black content use LLDPE, LDPE or EVA as the carrier. In order to ensure the dispersibility of the made carbon black masterbatch, a large amount of lubricants and dispersants are added to the process formula; in addition, in order to ensure Carbon black particles are completely fixed in the carrier resin without falling off, usually increasing the amount of carrier resin, which also leads to less carbon black content in the masterbatch

Abstract

The invention discloses a high-content carbon black master batch and a preparation method thereof, polyisobutene (PIB) is used as carrier resin, and a large amount of toner powder can be bonded and fixed in a small amount of the PIB by utilizing the characteristic of high bonding capacity of the PIB and the powder, so that the effect of almost no carrier is achieved, and meanwhile, the good dispersity of carbon black is kept. The master batch is simple in formula, simple in preparation process, large in carbon black filling amount and beneficial to cost control, and the property value of the color master batch is improved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-content carbon black masterbatch and a preparation method thereof. Background technique [0002] Most of the existing black masterbatches with high carbon black content use LLDPE, LDPE or EVA as the carrier. In order to ensure the dispersibility of the made carbon black masterbatch, a large amount of lubricants and dispersants are added to the process formula; in addition, in order to ensure Carbon black particles are completely fixed in the carrier resin without falling off, usually increasing the amount of carrier resin, which also leads to less carbon black content in the masterbatch. [0003] Glossary: [0004] PIB: Polyisobutylene. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies of the prior art. The present invention uses polyisobutylene (PIB) as the carrier resin, utilizes the characteristics of strong bond...
