High-tenacity oxidized graphene melamine resin and preparation method thereof

Abstract

The invention discloses a high-tenacity oxidized graphene melamine resin. The high-tenacity oxidized graphene melamine resin is prepared from the following raw materials in parts by weight: 1.6-2.1 parts of nano-crystalline cellulose, 0.2-0.3 part of rare earth cerium fluoride, 20-25 parts of melamine, 40-45 parts of 37% formaldehyde solution, 1.8-2.1 parts of oxidized graphene, 0.7-0.9 part of trifluoroethyl methacrylate, 0.7-0.9 part of polyacrylonitrile, a proper amount of dimethyl formamide, 0.2-0.3 part of polyoxyethylene, a proper amount of composite solvent comprising dimethyl formamide and dichloromethane of which the volume ratio is 1: 1, 0.3-0.5 part of tert-butyl hydroperoxide, a proper amount of citric acid, a proper amount of alkaline pH value modifier AMP-95 and a proper amount of ethyl alcohol. The resin disclosed by the invention is added with the oxidized graphene, so that the heat conductivity coefficient of the resin is improved by 41% compared with that of resin without adding oxidized graphene; by adding the nano-crystalline cellulose, the tenacity of the resin is improved, and the resin is prevented from cracking; by adding the rare earth cerium fluoride, the resin has a fluorescent effect.

Description

technical field [0001] The invention relates to the field of melamine resin materials, in particular to a high-toughness 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.

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.
