Problems solved by technology

However, since the melting point of most antistatic agents is lower than that of polyester, and has a strong external lubrication effect, if it is directly added during molding processing, it will cause processing difficulties, so it is better to add it to polyester in the form of antistatic masterbatch

Abstract

The invention discloses an antistatic master batch for polyester. The antistatic master batch comprises, by mass, 20-80% of polyester, 15-40% of an antistatic agent, 0.5-2% of a nucleating agent, 3-5% of a dispersant and 0.5-3% of a coupling agent. The antistatic master batch prepared in the invention has the characteristics of good processability, efficient and lasting antistatic performance, good compatibility, good thermal stability, low cost, use convenience and the like when the antistatic master batch is used in the antistatic modification of the polyester, and polyester prepared by using the antistatic master batch has a guaranteed antistatic performance and allows the surface resistivity of a product to reduce to 10<8>-10<10>omega.cm, so the antistatic master batch has a wide development prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic masterbatch for polyester. Background technique [0002] Polyethylene terephthalate (PET), referred to as polyester, is a crystalline polymer. Because it has the characteristics of high strength, good wear resistance, good resilience, and low cost, it occupies a considerable proportion in textiles. At the same time, polyester is an engineering plastic with excellent performance and a wide range of uses. However, due to the high resistivity of polyester, under the conditions of 65% relative humidity and 25°C, the moisture absorption rate is only 0.4%, and the resistivity is as high as 10. 14 Ω cm, it is very easy to generate static electricity, which limits its use in electrical and electronic industries. Antistatic polyester is polyester with antistatic properties. Generally, the resistivity of polyester is reduced by adding antistatic agents, so that it...
