Problems solved by technology

[0004] In addition, scholars have inserted ionic liquids into kaolinite layers to form nanostructures, which are widely used in electrode modification, catalysts, and detection of anions. Ionic liquid intercalated kaolinite has good thermal stability, electrical conductivity and optical properties. However, the preparation method of ionic liquid intercalated kaolinite abroad is single, and the cycle is long and the process is cumbersome. In the present invention, it is improved and simplified. The experimental process is simplified, the reaction time is shortened, and a better intercalation effect can be obtained at the same time

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an impact-resistant natural rubber material and a preparation method thereof. Background technique [0002] Kaolinite is one of the clay minerals of kaolin (kaolinite, dickite, nacre, halloysite, etc.) with l:l layered structure, composed of SiO4 tetrahedral layer and AlO2(OH)4 octahedral layer. 1:1 superimposed to form an asymmetric layered structure, thus establishing a large stack of dipoles, the interlayers are connected by (Al—O—H…O—Si) hydrogen bonds, and the interlayer distance is about 072nm. There is no isomorphic replacement in the crystal lattice, and the charge in the interlayer domain is basically balanced, so that cations cannot be adsorbed in its two-dimensional layer. In addition, due to the interaction of hydrogen bonding force and van der Waals force between layers, it has a considerable Cohesion, so the crystal layers are tightly connected and stable in perform...
