Surface-modified zirconium oxide injection molding solvent degreasing feed as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of zirconium oxide ceramic injection molding, and particularly relates to surface-modified zirconium oxide injection molding solvent degreasing feed as well as a preparation method and an application thereof. A feed is prepared from modified zirconium oxide powder and a binder, and the mass ratio of the modified zirconium oxide powder to the binder is (82-91): (9-18); wherein the mass ratio of a surfactant to skeleton resin to elastomer resin to a lubricating aid to a plasticizer in the binder is (3-6): (25-35): (8-15): (38-61): (3-6); after modification, the surface of the zirconium oxide powder is alkaline, and the zirconium oxide powder can be better combined with an acidic surfactant. According to the invention, the adopted binder has good compatibility, the skeleton binder has good supporting performance on the strength of a green body at a high temperature, and the binder adopts a plurality of different components, so that the use requirements of different products can be met; meanwhile, the preparation method provided by the invention is more beneficial to uniform mixing of the modified zirconium oxide powder and the binder.

Description

technical field

[0001] The invention belongs to the technical field of injection molding of zirconia ceramics, and in particular relates to a surface-modified zirconia injection molding solvent degreasing feedstock and a preparation method and application thereof. Background technique

[0002] Structural ceramics refer to a class of advanced ceramic materials mainly combined by ionic bonds and covalent bonds, which have excellent properties such as high strength, high hardness, high temperature resistance, wear resistance, and corrosion resistance. This kind of material has been widely used at home and abroad, covering chemical industry, metallurgy, machinery and other fields and people's daily life. In the past 20 years, structural ceramics have been used more and more in high-tech fields such as aerospace, communication electronics, biomedicine, and national defense. Zirconia, as an excellent representative, has attracted widespread attention.
