Problems solved by technology

[0003] At present, most of the domestic black masterbatches are not high in concentration, or are not easy to disperse
Carbon black itself is very easy to form aggregates due to its huge surface energy, and carbon black often exists in the form of aggregates, which makes it difficult to disperse in the polymer matrix and has uneven color, leading to problems such as broken ends and clogging.
Because carbon black itself has the characteristics of easy agglomeration, in order

Abstract

The invention discloses a method for preparing antistatic black master batch from graphene-coated carbon black. The method is characterized by comprising the following steps: (1) modifying carbon black by using a dispersing agent to obtain modified carbon black, uniformly mixing the graphene oxide and the modified carbon black in a solvent, and carrying out post-treatment to obtain graphene oxidecoated modified carbon black, wherein the dispersing agent is one or more of sodium dodecyl benzene sulfonate, APS, DL-602 and sodium lauryl sulfate; (2) reducing the obtained graphene oxide coated modified carbon black by using a reducing agent, and carrying out post-treatment to obtain graphene-coated carbon black; and (3) melting and uniformly mixing the obtained graphene-coated carbon black and a matrix master batch, and granulating to obtain the antistatic black master batch. The black antistatic master batch prepared by the method can greatly improve the dispersity, color uniformity andantistatic property of carbon black in the matrix material.

Description

technical field [0001] The invention relates to the field of preparation of carbon black colored master batches, in particular to a method and product for preparing antistatic black master batches by graphene-coated carbon black. Background technique [0002] Masterbatch (pigment concentrate) is widely used in the dyeing of plastics, synthetic fibers, films, cables, building materials and other products due to its advantages of high coloring strength, uniform color, safety and pollution-free, easy transportation and storage. [0003] At present, most of the domestic black masterbatches are not high in concentration, or are not easy to disperse. Carbon black itself is very easy to form aggregates due to its huge surface energy, and carbon black often exists in the form of aggregates, which makes it difficult to disperse in the polymer matrix, and the color is uneven, leading to problems such as broken ends and clogging. Because carbon black itself has the characteristics of ...
