Abstract

The invention provides a graphene 3D printing material. The graphene 3D printing material is prepared from, by weight, 20-60 parts of modified graphene, 30-50 parts of polyethylene glycol terephthalate, 2-8 parts of nano polytetrafluoroethylene, 1-5 parts of nano silica and 0.1-3 parts of an antioxidant, wherein the modified graphene is prepared from graphene oxide, ammonia water and polyethylene glycol diglycidyl ether, and the mass ratio of graphene oxide to polyethylene glycol diglycidyl ether is 100:(1-5).

Description

technical field [0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a graphene 3D printing material and a preparation method thereof. Background technique [0002] 3D printing (3DP) is a type of rapid prototyping technology, which is a technology that constructs objects by layer-by-layer printing based on digital model files and using adhesive materials such as powdered metal or plastic. Since 3D printing technology does not require molds, it can directly generate physical finished products according to the 3D CAD graphics designed by the computer, and obtain products with high precision and complexity. Therefore, 3D printing technology has become a rapidly developing emerging technology. [0003] Polyethylene terephthalate is the most important variety of thermoplastic polyester, commonly known as polyester resin. It has good physical and mechanical properties, long-term use temperature can reach 120 ° C, excellent el...
