Abstract

The invention discloses a modified zirconium phosphate-epoxy nanocomposite material and a preparation method thereof; the preparation method comprises: mixing an intercalation agent, a surfactant and a solvent, adding layered zirconium phosphate, oscillating evenly, and ultrasonically dispersing, Obtain the single-layer zirconium phosphate solution after stripping; adjust the pH of the single-layer zirconium phosphate solution with a stripping agent, centrifuge, wash, and pour off the supernatant; add zirconium phosphate and modifier to the solvent, and heat Stir and react at high temperature for 12-24 hours, after washing and drying, the modified zirconium phosphate is obtained; the modified zirconium phosphate is dispersed in a solvent, mixed with the ethanol solution of the curing agent, added epoxy resin, and stirred evenly to obtain the modified zirconium phosphate- Epoxy nano-composite material: Compared with epoxy resin, the modified zirconium phosphate-epoxy nano-composite material of the present invention has significantly improved mechanical properties and anti-corrosion properties.

Description

technical field [0001] The invention relates to a method for modifying a layered material, in particular to a modified zirconium phosphate-epoxy nanocomposite material and a preparation method thereof; it belongs to the technical field of nanozirconium phosphate composite material. Background technique [0002] In recent years, more and more attention has been paid to the application of inorganic layered compounds introduced into polymers as fillers, such as montmorillonite, hydrotalcite, layered zirconium phosphate, etc. The introduction of inorganic layered compounds makes the thermal stability, mechanical Enhanced performance, gas barrier and flame retardancy. However, the easy agglomeration of nanoscale inorganic compounds and the incompatibility with polymers are two main aspects that limit their applications. Achieving highly exfoliated nanosheets in polymer matrices has become the main focus of research in recent years, while the aspect ratio of nanosheets has a grea...
