Abstract

The invention relates to a polyolefin antistatic composition and a preparation method thereof and belongs to the technical field of polyolefin compositions. The polyolefin antistatic composition is prepared from 25 to 70 parts by mass of high-density polyethylene, 5 to 15 parts by mass of linear low-density polyethylene, 20 to 50 parts by mass of antistatic master batches and 5 to 10 parts by mass of conductive master batches. The preparation method comprises blending high-density polyethylene, linear low-density polyethylene, antistatic master batches and conductive master batches and carrying out granulation. The polyolefin antistatic composition solves the problem that the traditional polyolefin subjected to antistatic modification has poor antistatic effects and poor mechanical properties. The polyolefin antistatic composition has good antistatic performances, good impact resistance and good shaping performances and has a high modulus and good balance of rigidity and toughness. The preparation method has simple processes and is easy to operate.

Description

technical field [0001] The invention relates to a polyolefin antistatic composition and a preparation method thereof, belonging to the technical field of polyolefin compositions. Background technique [0002] Polyethylene has a wide range of applications due to its excellent mechanical properties, chemical stability, electrical insulation, processability and high cost performance. As a result, static electricity is generated, which can cause dust collection, electric shock, and even sparks and explosions. In order to avoid such accidents, in some cases the use of plastic products must be treated with antistatic. [0003] Traditional polyethylene antistatic modification often adds antistatic agents, or adds more conductive fillers. Ordinary antistatic agents will migrate, and the antistatic effect will decrease or disappear over time. The price of polymer permanent antistatic agents is expensive, and the amount of addition is large, the cost is high, the effect is not outst...
