Problems solved by technology

[0006] Polyester is the most commonly used textile fiber raw material, and it is widely used in many special fabrics. However, most of the antistatic agents prepared by the above invention and the prior art are small molecule antistatic agents, which require a certain humidity to exert their antistatic properties. The effect of static electricity, and it is also prone to migration, and the antistatic effect will be greatly reduced after the loss

Abstract

The invention relates to the field of chemical industry, in particular to a preparation method of a polymer polyester antistatic agent; the invention prepares a salt-containing dibasic acid, and then uses the dibasic acid and a sulfonic acid group-modified polyether dibasic acid Alcohol reacts to form polyether ester macromolecules containing metal ions, and then reacts with diisocyanate chain extension to prepare a polymer antistatic agent with a benzene ring structure. This antistatic agent can use the double conductivity of polyether ester and metal ions The antistatic effect is improved; and the polyether glycol modified by sulfonic acid group contains sulfonic acid group, which can further strengthen its antistatic effect; the polyether ester macromolecule of the present invention is a kind of embedding compound containing metal salt Segment polymer, which has good antistatic effect as an antistatic agent, and has good durability, heat resistance and washing stability, and has good compatibility and processability with polyester materials.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a preparation method of a polymer polyester antistatic agent. Background technique [0002] When polymers are rubbed, due to their high resistance, the generated static electricity is not easy to release. With the accumulation of static charges, the static voltage is formed, which makes the polymer products easy to absorb dust and affects the surface properties and transparency of the products. Moreover, it can also affect the performance and processing performance of the product. What's more, when static electricity causes corona discharge or spark discharge, if there are flammable and explosive substances in the surrounding environment, it will also cause fire or explosion, causing vicious accidents. [0003] CN1011978B An antistatic agent containing cationic and / or amphoteric water-soluble or water-dispersible heat-reactive end-capped urethane prepolymers as main components, ...
