Abstract

The invention provides a method for utilizing electrostatic self-assembly to prepare a natural rubber-carbon nano-tube composite material. The method comprises the following steps of adopting surfactant to modify the surfaces of carbon nano-tubes so as to enable the surfaces of the carbon nano-tubes to have positive charges, directly mixing the carbon nano-tubes with lacteous natural rubber with negative charges and utilizing self-assembly in an electrostatic adsorption principle to prepare the natural rubber-carbon nano-tube composite material. The preparation method realizes that the carbon nano-tubes are uniformly dispersed in the natural rubber and have good compatibility with the natural rubber, thereby providing technical guarantee for preparing nano-composite rubber products with excellent comprehensive properties.

Description

[Field of invention]

[0001] The invention relates to a method for preparing a natural rubber composite material, in particular to a method for preparing a natural rubber-carbon nanotube composite material by electrostatic self-assembly. [Background technique]

[0002] Carbon nanotubes are a new type of carbon structure that was discovered in 1991. It is a seamless, hollow tube formed by graphene sheets formed by carbon atoms. Due to the small radial size of carbon nanotubes, the diameter of the tube is generally several nanometers to tens of nanometers, and the length of carbon nanotubes is generally several micrometers to tens of micrometers, so carbon nanotubes are considered to be a typical one. Dimensional nanomaterials. Carbon nanotubes have excellent mechanical properties, with a tensile strength of 50GPa to 200GPa, about a hundred times that of steel, but a density that is only one-sixth of steel. In addition, carbon nanotubes have many properties such as good chemi...
