Abstract

The invention discloses a modified zirconium phosphate-epoxy nanometer composite material and a preparation method thereof. The preparation method comprises the following steps: mixing an intercalation agent, a surfactant and a solvent, adding layered zirconium phosphate, oscillating uniformly and ultrasonically dispersing to obtain a single-layer zirconium phosphate solution after stripping; adopting a stripping agent to adjust the pH of the single-layer zirconium phosphate solution, centrifuging, washing and discarding supernatant liquid; adding zirconium phosphate and a modifier into the solvent, performing stirring reaction at the temperature of 80 to 100 DEG C for 12 to 24 hours, washing and drying to obtain modified zirconium phosphate; dispersing the zirconium phosphate with the solvent, mixing with an ethanol solution of a curing agent, adding epoxy resin and stirring uniformly to obtain the modified zirconium phosphate-epoxy nanometer composite material. Compared with the epoxy resin, the modified zirconium phosphate-epoxy nanometer composite material significantly improves the mechanical property and the anti-corrosion property.

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...
