The high-efficiency antistatic mother particle consists of carrier, antistatic agent and other additives. The additive is added into the plastic, so that static electricity generated by the insulating property of the high polymer can be avoided, the packaging requirement of IT products and the production of special antistatic products can be met, and the dustproof effect on the surfaces of the products is good. The polyethylene material has the advantages of high cost performance, good mechanical property, stable thermal property, excellent processability and electrical insulation property, and the like, is widely applied to various fields of industry, agriculture, medical treatment and health, scientific research, daily life and the like, but has poor surface conductivity, and is easy to cause electrostatic accumulation on the surface of a product due to friction, extrusion and the like in the using process to cause dust absorption, electric shock, even explosion and other serious accidents after sparks are generated. Therefore, the development and application of the antistatic master batch are rapidly developed. At present, researches on the antistatic performance of polyethylene master batches are relatively few, and the antistatic aim is achieved mostly by adding conductive carbon black, but the method has the problems of large addition amount, difficulty in dispersion, single color and inconvenience for large-scale production.
The traditional antistatic master batch also has the problem that the antistatic effect and the antistatic time cannot be further improved, so that the problem that how to improve the antistatic effect and the antistatic time of the traditional antistatic master batch cannot be further improved is to be solved.
