Problems solved by technology

However, whether it is the original natural inorganic state montmorillonite or the modified organic state montmorillonite, it is difficult to fully and effectively disperse the montmorillonite in the polymer, and the exfoliated lamellae are easy to agglomerate and form a separate phase. Fundamentally weakens the reinforcing effect of montmorillonite platelets on the polymer

Abstract

The invention discloses a preparation method of graphene modified organic montmorillonite for enhancing a polymer. The preparation method is characterized by comprising the following steps: firstly, carrying out chemical structure modification on a montmorillonite crystal lattice by utilizing a diluted acid solution, soluble copper salt and soluble zinc salt; then introducing high molecular weightpolyethylene oxide into an interlayer region; adding graphene into interlayers, so as to prepare the graphene modified organic montmorillonite which can be sufficiently and effectively dispersed in the polymer; the graphene modified organic montmorillonite has excellent dispersion performance in polymers including resin, fibers, plastic and the like, and properties including mechanical strength,mechanical property, heat resistance and the like of various polymers are effectively improved.

Description

technical field [0001] The invention relates to the field of modification of organic montmorillonite, in particular to a method for preparing nanoscale organic montmorillonite which can be widely used in plastics, resins, rubber and other polymers. Background technique [0002] As we all know, polymer materials have excellent flexibility, water resistance, electrical and thermal insulation, and are light in weight and easy to process. They are indispensable materials in today's world. However, polymer materials also have many weaknesses, such as poor mechanical strength, heat resistance, and dimensional stability, which severely limit their further applications. On the contrary, inorganic materials have the advantages of good strength, rigidity, heat resistance, aging resistance and dimensional stability. How to perfectly compound inorganic materials and organic materials has always been a hot spot in scientific and technological research and development. [0003] Among th...
