Abstract

The invention relates to a reinforced super-electrostatic polyester composition which is prepared from the following components in parts by weight: 50-90 parts of poly(terephthalic acid)-1,4-cyclohexanedimethanol, 0.1-15 parts of a conducting additive, 1-20 parts of ionic liquid, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant. The invention also provides a preparation method of the polyester composition. The reinforced super-electrostatic polyester composition and the preparation method thereof have the advantages that for the polyester composition provided by the invention, the ionic liquid is utilized to enable the conducting additive which is liable to agglomerate to be well dispersed and effectively dispersed in a polyester material uniformly, so that a conductive network is formed in a product, and the product has very low surface resistance and a very strong antistatic effect.
