    • A composite clay material with the interlayer distance sufficiently expanded by dispersing clay mineral in a low polar polymer on a molecular level and the method for producing the same, blend material and composite clay rubber material using the same and the production method thereof. The composite clay material is formed of a clay mineral rendered compatible with an organic material through ionic bonding to an organic onium ion having 6 or more carbon number and a main guest molecule having a polar group in its main chain and side chain and molecular length equal to or larger than that of said organic onium ion. The main guest molecule is incorporated at least partially into an interlayer section of the clay mineral which has a hydrogen bonding with the polar group of the main guest molecule. The main guest molecule preferably has a molecular weight ranging from about 100 to 100000. Alternatively a first guest molecule having a polar group and molecular length equal to or smaller than that of the organic onium ion and a second guest molecule having no polar group therein and molecular length larger than that of the organic onium ion are incorporated into the interlayer section of the clay mineral instead of the main guest molecule. The above obtained clay composite material may be mixed with the rubber material.
    • 通过在分子水平上将粘土矿物分散在低极性聚合物中的层间距离充分膨胀的复合粘土材料及其制造方法,使用其的混合材料和复合粘土橡胶材料及其制造方法。 复合粘土材料由与有机材料相容的粘土矿物形成,通过离子键合至具有6个或更多个碳数的有机鎓离子,并且主链和侧链具有极性基团的主客体分子和分子长度相等 达到或大于所述有机鎓离子的浓度。 主客体分子至少部分地并入与主客体分子的极性基团具有氢键的粘土矿物的中间层部分中。 主客体分子优选具有约100〜100000的分子量。或者,具有极性基团和分子长度等于或小于有机鎓离子的分子量的第一客体分子和不具有极性基团的第二客体分子, 大于有机鎓离子的分子长度被掺入粘土矿物的中间部分而不是主客体分子。 将上述得到的粘土复合材料与橡胶材料混合。
