Abstract

The invention discloses a PET polyester film antistatic agent and a preparation method thereof. The antistatic agent is a copolymer of unsaturated aliphatic polyester and sodium p-styrenesulfonate, and the mass ratio of the unsaturated aliphatic polyester to the sodium p-styrenesulfonate is 70-85:30-15; aliphatic polyester oligomer is synthesized, the aliphatic polyester oligomer is mixed with maleic anhydride to prepare the unsaturated aliphatic polyester, and the unsaturated aliphatic polyester is copolymerized with the sodium p-styrenesulfonate to synthesize the antistatic agent. Anti-static characteristics and high transparency can be well balanced, and PET polyester films processed with the antistatic agent can keep the anti-static characteristics for a long time as well as maintain high transparency.

Description

technical field [0001] The invention relates to an antistatic agent and a preparation method thereof, in particular to a PET polyester film antistatic agent and a preparation method thereof. Background technique [0002] PET (polyethylene terephthalate) has the characteristics of high strength, good wear resistance, good resilience and low cost, so it occupies a considerable proportion in textiles. At the same time, PET is an engineering project with excellent performance and wide application. plastic. However, due to the high resistivity of PET, under the conditions of 65% relative humidity and 25°C, the moisture absorption rate is only 0.4%, and the surface resistance is as high as 10. 14 Ω. Therefore, it is very easy to generate static electricity, which limits its application in industries such as electronics and electricity. The antistatic of PET is generally to reduce the resistivity of PET by adding antistatic agent, so that it can effectively dissipate the charge,...
