High-performance modified glass material used for 3D printing and preparation method of glass material

Abstract

The invention relates to a high-performance modified glass material used for 3D printing. The glass material is composed of the following substances in percentages by mass: 1.5%-6.8% of monocrystalline silicon powder, 1.1%-3.5% of nano bentonite, 1.1%-3.5% of nano magnesia, 3%-18% of graphene, 5%-20% of N,N-dimethylamide, 1.2%-3.5% of polymethacrylate, 0.1%-0.5% of isopropanol, 0-1.1% of chromiumoxide, 0-1.5% of titanium dioxide, 0-1.3% of zinc oxide, 0-1.5% of lithium oxide, 0.1-2.3% of propylene glycol mono-butyl ether, and the balance of boron glass powder; and the preparation method of the glass material includes the four steps of preparation of a modified liquid, mixing of materials, preparation of a glass substrate and acid pickling. The method provided by the invention has the advantages of low production costs, low raw material and production pollution, a simple and easy production process, high processing efficiency, and relatively low processing energy consumption; and the method effectively improves the wear resistance, impact resistance and hot processing and forming performance of the glass surface, thereby effectively improving the surface quality and machining precision of processing workpieces of 3D printing while greatly improving a glass body to meet processing and forming operation of 3D printing.

Description

technical field [0001] The invention relates to a high-performance modified glass material for 3D printing and a preparation method thereof, belonging to the technical field of 3D printing. Background technique [0002] At present, 3D printing technology has been widely used in many processing fields such as molds and parts. It is very common to use 3D printing equipment to shape glass materials. The glass materials used for printing equipment are often traditional glass bodies. Although they can meet the needs of use, they all have poor surface structure accuracy, large thermal shrinkage deformation, workpiece product structural strength, and wear resistance after 3D printing. The performance is relatively poor and cannot effectively meet the needs of the actual use of the workpiece, which severely limits the promotion and application of 3D printing technology. Therefore, in view of this situation, it is urgent to develop a glass material that can effectively meet the needs...
