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.

Description

technical field [0001] The invention relates to the technical field of nanometer material dispersion and polymer material processing, in particular to a reinforced superstatic polyester composition and a preparation method thereof. Background technique [0002] With the arrival of the era of replacing steel with plastic, static electricity problems are becoming more and more common in our daily life. The electrostatic charge on the surface of the material is transferred with the generation of potential difference, and a certain harmful discharge effect will occur. [0003] PCT resin is poly-1,4-cyclohexanedimethanol terephthalate. Compared with PC, it contains cyclohexanedimethanol ester functional groups, and its glass transition temperature is lower than that of polycarbonate. It is a better polyester Engineering substrates. [0004] Carbon nanotubes are one-dimensional nanomaterials with high current densities (over 109A / cm 2 ), excellent thermal conductivity (about 66...
