In the invention, an antistatic lining barrel is provided, wherein an iridium oxide material is mainly adopted as a main antistatic agent, but iridium oxide is taken as a metal oxide, so that the dispersibility of iridium oxide in a high polymer material is poor, the antistatic performance of the whole material is not uniform, and the whole antistatic effect is poor. The coupling agent and the ether compound are required to be added, so that the dispersibility can be improved, and the performance of the obtained material is more stable.
In addition, in experiments, the zinc butyrate is added in a small amount, so that the dispersing capacity can be greatly improved, and the dispersity and the antistatic performance can be greatly improved.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
