摘要： A new mixed layer silicate useful for industrial materials is provided.The mixed layer silicate is obtained by a specific synthesis method. The mixed layer silicate includes non-swelling 2:1 type layered silicate layers having a layer charge of 0 or non-swelling 2:1 type layered silicate layers having a layer charge of 0.6 to 1 and including potassium ions between layers and swelling 2:1 type layered silicate layers having a layer charge of 0.2 to 0.6 and including exchangeable cations between layers. The mixed layer silicate has a structure in which individual layers are laminated in a regular order in a lamination direction (regularly mixed layer structure). Furthermore, an organic-inorganic composite material is prepared through intercalation of a positive charge organic compound into the swelling 2:1 type layered silicate layers in the resulting mixed layer silicate, and the resulting organic-inorganic composite material is swollen and peeled in a polymer, so that a polymer composite material in which silicate sheet sets, each set including a few silicate sheets, are homogeneously dispersed in the polymer can be obtained.

摘要： Conventional nanocomposites using swelling layered silicates, which are low specific gravity and have markedly improved heat resistance, rigidity and gas barrier compared with talc or mica filling composites, are available. They are, however, much inferior to glass fiber filling composites (FRP) for rigidity and heat resistance if not regarding difference of specific gravity and they may not respond to current high level requirements. The inventors have found that an organic-inorganic composite can be formed by substituting K ions between layers of high-crystalline non-swelling layered silicates composed of mica and having primary particles of large particle size with any positive charged organic compound under specific conditions, leading to completion of the invention which enables production of polymer composite materials having the layered silicates delaminated and dispersed. This organic-inorganic composite is useful as a sheeted filler having a high aspect ratio and the aspect ratio of which further can be increased by dispersing it in a polymer matrix.
