Abstract

The invention relates to a preparation method of graphene oxide reinforced epoxy resin adhesive, in particular to a preparation method of highly-dispersed graphene oxide reinforced epoxy resin adhesive. The invention aims at solving the technical problems that the existing graphene oxide reinforced epoxy resin adhesive is difficult to disperse in a preparation process, and an organic solvent usedin the dispersing process causes environmental pollution. The preparation method comprises the steps of 1, preparing graphene oxide by using a chemical oxidation method; 2, dispersing the graphene oxide in epoxy resin; 3, preparing the graphene oxide reinforced epoxy resin adhesive. According to the preparation method, the fully-exfoliated and highly-dispersed graphene oxide reinforced epoxy resinadhesive is prepared by using the conventional equipment such as a high-speed emulsifier and a three-roll grinder; an organic solvent and any other additive are not used in the dispersion process, sothat the preparation method is beneficial to environmental protection, and the adverse effects, caused by the use of additives, on the other properties of an epoxy resin system are avoided.

Description

technical field [0001] The invention relates to a preparation method of graphene oxide reinforced epoxy resin adhesive. Background technique [0002] Epoxy resin has the advantages of excellent mechanical properties, chemical stability, insulation, etc., and because of its low price and wide applicability, it plays a vital role in many fields such as electronics, machinery, automobiles, construction, and aerospace. , but also one of the indispensable basic materials. While epoxy resins have many advantages, they also have some disadvantages. Since the epoxy resin forms a high-density cross-linked three-dimensional network structure during the curing process, it is very brittle and poor in toughness. At the same time, with the rapid development of industry, the performance requirements of epoxy resin are getting higher and higher. Therefore, the preparation of epoxy resins with high toughness, high strength, high modulus and high temperature resistance has become one of the...
