Abstract

The invention discloses a long-lasting antistatic polyester random copolymer. The long-lasting antistatic polyester random copolymer is prepared from terephthalic acid, ethylene glycol and an antistatic functional monomer. Through use of the terephthalic acid, ethylene glycol and antistatic functional monomer, the long-lasting antistatic polyester random copolymer obtained by copolymerization has good antistatic performances. Through mixing of the long-lasting antistatic polyester random copolymer and a PET material, the long-lasting antistatic polyester random copolymer can move to the surface of PET so that antistatic properties of the PET surface are greatly improved and the problem that the existing production technology produces accumulation of static electricity on the surface of PET plastic or fiber products is solved. The long-lasting antistatic polyester random copolymer realizes a low cost and is prepared through simple processes. The random copolymer has a PET chain section and thus the random copolymer has good adhesion with the substrate PET, has good antistatic durability, has excellent mechanical properties and high temperature stability and has a great application prospect and market value.

Description

technical field [0001] The invention relates to the synthesis and application field of a random copolymer polyester, in particular to a synthesis method and application of a long-acting antistatic polyester random copolymer. Background technique [0002] In the middle of the 20th century, with the rapid development of industrial production and the rapid application of polymer materials, high-resistivity polymer materials such as plastics, fibers, rubber and other products are widely used in daily life and production processes. Due to the insulating properties of these materials, during use and storage, the surface of the material is prone to static electricity accumulation, which causes great inconvenience to production and life. When the static electricity accumulation reaches a high level, there is a great safety hazard, especially Production and use of electrostatic sensitive materials (such as light oil, gunpowder, solid state electronic devices, etc.). Electrostatic ha...
