Problems solved by technology

Only when the traditional antistatic agent molecules migrate to the surface can it work. The antistatic agent molecules inside the plastic continue to migrate to the surface until they are completely consumed, so its effect is only effective within a certain time range

Abstract

The invention relates to a permanent anti-static composition for plastic. The anti-static composition comprises the following components in percentage by mass: 83 to 98 percent of macromolecular polymer, 1 to 12 percent of anti-static agent and 1 to 5 percent of white carbon black. The invention also provides a preparation method for the anti-static composition. The preparation method comprises the steps of uniformly mixing the materials by using a high mixing machine according to the formula and extruding and pelleting to obtain the anti-static composition. The permanent anti-static composition for plastic has a good and wide processing using range, is suitable for various kinds of plastic, has excellent dispersity on plastic, maintains the characteristics of plastic and has excellent anti-static performance.

Description

technical field [0001] The invention relates to a permanent antistatic composition for plastics and a preparation method thereof. Specifically, the invention relates to a polymer type permanent antistatic composition for plastics and a preparation method thereof. Background technique [0002] Most polymer materials are prone to static electricity accumulation during production and use, resulting in adverse phenomena such as electrostatic dust collection and electrostatic discharge. In severe cases, sparks can be generated, causing fire or explosion, and bringing troubles to industrial production and daily life. [0003] At present, plastic products are widely used as packaging materials, etc., but the surface resistance of ordinary plastics is greater than 10 12 More than Ω, the conductivity is extremely poor, and static electricity is easy to be generated during packaging and transportation, which is not easy to conduct away, causing great harm to the product. With the in...
