Abstract

The invention discloses a universal color master batch with high carbon black content and high melt flow rate and a preparation method thereof. When the mass content of carbon black in the universal color master batch is up to 50 to 60%, the universal color master batch still has higher melt flow rate, is easy to disperse in polymer melts with different viscosities, and particularly has PA and PETsystems with lower viscosities in the melt at high temperature. Meanwhile, the universal carbon black master batch is suitable for non-polar or weak-polar polymer systems such as PE, PP and PS, is also suitable for polar polymer systems such as PA, PVC, PET and ABS, and is a true universal carbon black master batch. The universal color master batch with high carbon black content and high melt flow rate is prepared from the following raw materials in parts by mass: 15 to 30 parts of oxidized polyethylene wax, 10 to 20 parts of polyolefin resin, 3 to 5 parts of chlorinated polyethylene, 50 to 60 parts of high-structure-degree carbon black and 0.5 to 1.0 part of a stabilizer.

Description

technical field

[0001] The invention relates to a carbon black masterbatch and a preparation method, more specifically to a general-purpose color masterbatch with high carbon black content and high melt flow rate and a preparation method. Background technique

[0002] Carbon black is an important functional filler. It is widely used in the processing and application of polymer materials such as synthetic rubber, synthetic resin, synthetic fiber, coatings, and adhesives. At the same time, there are many types of carbon black, and the performance differences are relatively large. , the requirements and functions are not the same in different materials and application fields. For example, in the formula of rubber materials, carbon black is mainly used as a reinforcing filler. Often, according to different rubber performance requirements and use conditions, you can choose high wear-resistant carbon black, semi-reinforcing carbon black, spray carbon black, and fast extrusion carb...
