Description

technical field [0001] The invention relates to the field of melamine resin materials, in particular to a graphene oxide melamine resin and a preparation method thereof. Background technique [0002] Graphene is a carbonaceous material with a two-dimensional planar honeycomb lattice structure formed by a single layer of carbon atoms tightly packed. Its unique nanostructure determines that it has a series of excellent properties. The theoretical specific surface area is as high as 2600㎡ / g; thermal conductivity The coefficient is as high as 5000W / (m.K), which is 5 times that of diamond, and the strength is the highest among known materials, reaching 130GPa, which is more than 100 times that of steel. At present, graphene is considered to be used in functional composite materials, nano devices, and energy storage. Materials and catalyst supports have a wide range of application space. [0003] Using the excellent properties of graphene to prepare graphene / polymer composites, t...

Problems solved by technology

However, a single graphene oxide has limited performance improvement of the resin, and further improvement of the performance of the resin is needed. The performance of the resin can be improved by improving the process and composition; for example, it is necessary to improve the strength, water resistance, thermal stability, wear resistance, Hardness, resistance to chemicals, poor toughness, easy to break, short storage period and other properties make the resin more widely used in furniture, vehicles, construction, etc.
