製造方法に関する。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a polyester composite material and a method for producing the same, and more specifically, to a thermoplastic aromatic polyester composite material in which layered clay minerals are uniformly dispersed and bonded. It relates to its manufacturing method.

For example, it has good properties such as elastic modulus), electrical insulation, chemical resistance, processability, and surface appearance (for example, surface clarity), and is widely used as an engineering plastic or as a film material. There is.

There has been a problem in that the application to parts etc. that are used in places is restricted.

ものであった。In order to deal with this problem, it has been proposed, for example, to blend an inorganic filler such as clay treated with organic silane with polyester (for example, JP-A-5124653, JP-A-51 -24654, etc.). However, in this conventional technology, since pretreatment to separate each unit layer of the layered clay mineral from each other is not performed, threads made of giant clay mineral particles (block-like particles in which many unit layers are stacked and fixed) , filter clogging, thread breakage, and film tearing occur during the film forming process. In particular, polyethylene terephthalate has had problems such as fisheyes (fine fish-eye defects) and dropouts in magnetic tapes (missing magnetic recording). In addition, in this prior art, the layered clay minerals are separated into each unit layer and not uniformly dispersed in the material, and the layered clay minerals also form a higher-order three-dimensional structure (for example, a bridge structure) in the material. Improvements in rigidity, heat resistance, and water resistance were also insufficient since they hardly contributed to formation.
