Abstract

The invention provides a preparation method of a zirconia ceramic ferrule and a preparation method of a zirconia powder base material used for the zirconia ceramic ferrule. The titanium dioxide used in the present invention makes the material have excellent fluidity in the injection molding process, and the synergistic effect of magnesium oxide, zinc oxide and titanium oxide obtains better linear expansion coefficient and thermal stress performance than pure zirconia ceramics, and improves the entire system at the same time Excellent thermomechanical properties make the material have high strength. Second, ethylene-vinyl acetate copolymer has high elasticity and toughness. Polyurethane elastomer, polyacetal resin, high-melt strength polypropylene, etc. are interspersed in zirconia powder through ethylene-vinyl acetate copolymer to polymerize these organic The adhesive forms a structure that intersects the network very well, and a stable structural system is obtained, so that the formed ceramic ferrule is not easily deformed. Third, the polyaldehyde resin is used as an organic binder to make the molded body have high strength, good shape retention, fast degreasing speed and high precision.

Description

technical field [0001] The invention relates to the technical field of ceramic electronic components, in particular to a preparation method of a zirconia ceramic ferrule. Background technique [0002] In the field of optical fiber communication technology, optical fiber connectors can be used to transmit optical signals, and their core and basic components are ferrules, which play the role of media for connection, conversion, and data transmission. They are the most basic and important components of a series of optical communication products. Passive components. [0003] Optical fiber connectors, commonly known as live joints, are passive components used to stably but not permanently connect two or more optical fibers. The non-permanent fixed connection between optical fibers is an indispensable passive component in optical fiber communication systems. The most commonly used ceramic materials are alumina and 3mol yttrium oxide not completely stabilized zirconia (PSZ). Amo...
