High-solid-phase-content aluminum oxide photosensitive ceramic material and preparation method thereof

Abstract

The invention discloses a high-solid-phase-content aluminum oxide photosensitive ceramic material and a preparation method thereof. The preparation method comprises the following steps of: dispersingaluminum oxide ceramic powder into a surfactant dilute solution for modification treatment, and then performing drying and ball milling to obtain modified ceramic powder; mixing photosensitive resin,a plasticizer, a polymerization inhibitor, a dispersing agent and a photoinitiator to prepare a photosensitive premixed solution; and adding the modified ceramic powder into the premixed solution, fully dispersing the substance, and removing bubbles to obtain the high-solid-phase-content aluminum oxide photosensitive ceramic material. The ceramic photosensitive materials with the same solid phasecontent and different states are prepared so as to meet different requirements of various ceramic 3D printing.

Description

technical field

[0001] The invention belongs to the technical field of 3D printing, and in particular relates to a photosensitive ceramic material with high solid content of alumina and a preparation method thereof. Background technique

[0002] High-performance ceramics are indispensable key materials for the development and application of modern high-end technology due to their excellent properties such as high hardness, high compressive strength, good wear resistance, high temperature resistance and acid and alkali corrosion resistance, and have been widely used in aerospace , biomedicine, machinery, electronics, energy, chemical industry and other industrial technology fields. However, with the rapid development of industrial technology and the continuous expansion of material application fields, traditional ceramic manufacturing technology cannot meet the needs of rapid manufacturing of high-end products. The 3D printing process is simple, the processing cost is low, a...
