Problems solved by technology

[0004] However, the antistatic performance of commonly used surfactant-type antistatic agents is greatly affected by air humidity. In the case of low humidity, the antistatic performance will be greatly weakened or even lost, which leads to certain limitations in its use.
Although the polymer permanent antistatic agent is less affected by humidity, its cost is high and the amount added is large, so it is only used in some high-end occasions

Abstract

The invention relates to the field of antistatic agents, and discloses a low-humidity-resistant antistatic agent special for polyolefin, which comprises the following components by mass: 31-55% of a fatty amine polyoxyethylene ether surfactant; 19-35% of higher fatty alcohol; 3-34% of an ionic compound; 0-5% of nano oxide; and 3-16% of a functional auxiliary dispersant. The antistatic agent provided by the invention is specially used for polyolefin materials, can realize excellent antistatic performance with a small dosage, and has excellent antistatic performance under low humidity. In addition, the antistatic agent disclosed by the invention is white to light yellow powder or flakes in appearance, so that the transparency and mechanical properties of a product are hardly influenced.

Description

technical field [0001] The invention relates to the field of antistatic agents, in particular to a special antistatic agent for polyolefin resistant to low humidity. Background technique [0002] Due to its excellent comprehensive properties, polyolefin plastics are widely used in various fields such as household appliances, transportation, electronic appliances, and national defense industry. However, because polyolefin plastics usually have electrical insulation, the surface resistance of PE and PP is generally 10 16 ~10 20 Ω. Therefore, once friction is electrified, it is not easy to eliminate, thus generating static electricity. Due to electrostatic attraction, plastic products will absorb dust and other dirt in the air, affecting the appearance of the product. Due to the influence of static electricity, adhesion occurs during the manufacturing process of plastic films. In addition, static electricity can also cause accidents such as fire, explosion, and electric sho...
