preparation example
[0045] Preparation examples 1-11 are composite antistatic agents.
[0046] In preparation example 1~6, the preparation method of composite antistatic agent is as follows:
[0047] Weigh the anionic antistatic agent and nonionic antistatic agent, mix them uniformly and form agglomerates at a mixing temperature of 45°C and a mixing speed of 700r / min, and roll them into granules after cooling to room temperature.

Abstract
The invention relates to the field of plastic additives, and discloses an antistatic composition as well as a preparation method and a use method thereof. The antistatic composition comprises the following raw materials: a modified antistatic agent, a defoaming agent, a coupling agent, an emulsifier and a diluent, wherein the modified antistatic agent is prepared by compounding a composite antistatic agent, super absorbent resin and silochrom. The antistatic composition is prepared by uniformly mixing a composite antistatic agent, super absorbent resin and silochrom to obtain a modified antistatic agent, then adding a defoaming agent, a coupling agent, an emulsifier, a diluent and polyethylene wax, uniformly mixing in a molten state to obtain a mixture, finally cooling the obtained mixture, and grinding and crushing to obtain the antistatic composition. And the antistatic composition is added into the PE plastic according to the percentage accounting for 1-3% of the total mass, so that the antistatic capability of the PE plastic is improved, and the potential safety hazard when a PE plastic product is used is reduced.
Description
technical field [0001] The application relates to the field of plastic additives, in particular to an antistatic composition and its preparation method and use method. Background technique [0002] When two materials with different physical states or chemical compositions are in close contact, the charges on the surface will be redistributed, and electrons will be transferred from the side with a small binding force to the side with a large binding force. At this time, the number of charges on the contact interface is equal , The polarity is opposite. When re-separated, due to the existence of the potential difference, the electrons cannot be completely restored, and at this time, the surface of each material will be charged with excessive positive or negative charges, which is static electricity. [0003] PE plastic has poor electrical conductivity and is a good electrical insulator. It will generate static electricity accumulation when it is in contact with or rubbed with...
