Abstract

The invention discloses a method for preparing a graphene photocurable resin nanometer material. The method comprises the following steps: (1) preparing graphene oxide; (2) dropwise adding a mixing solution of acrylic acid, N,N-dimethylaniline and hydroxyanisole into epoxy resin with the temperature of 60 DEG C; heating, reacting at 100-110 DEG C until the acid value is between 4-5 mg.KOH / g, stopping heating, and obtaining a prepolymer; (3) adding the graphene oxide obtained from step (1) to the prepolymer obtained in the step (2), mixing, and then adding a trimethylolpropane triacrylate monomer and a photoinitiator, mixing and stirring in a dark room for 0.5 to 1 h, then carrying out ultrasonic mixing for 0.5 to 1h, removing bubbles in vacuum to obtain a tan pouring solution. The graphene oxide provided by the invention is added to increase the photo-curing rate of the nanometer material with a maximum curing rate of 96.6%.

Description

technical field

[0001] The invention belongs to the technical field of materials for 3D printing, and in particular relates to the preparation and pouring method of graphene light-cured resin nanomaterials. Background technique

[0002] 3D printing technology is a new type of manufacturing technology that emerged and developed in the late 1980s. Because its technology can process parts of any complexity, it can even make parts that are difficult to form by traditional technology, so it has developed rapidly. At present, 3D printing technology has been widely used in aerospace, automobile, mold, electronics, education and other fields. Photocuring molding is a typical process in 3D printing technology. The molding material is liquid photosensitive resin. The molding parts have the characteristics of good surface quality and high molding precision. At present, most of the molding materials used in China rely on imports. Imported materials are expensive and printing costs are ...
