Ceramic protective shell material for sensor packaging, shell system and preparation method
The invention relates to the technical field of piezoelectric ceramics, and in particular, relates to a ceramic protective shell material for sensor packaging, a shell system and a preparation method;the ceramic protective shell material for sensor packaging comprises the following raw material components: 55%-65% of a main material and 35%-45% of a pore forming agent; the shell system comprisesa box body and a cover body, a through groove is reserved in one side of the bottom of the box body, two blind holes are formed in the edge of the top of the box body, the cover body is located abovethe box body, and two pin rods are bonded to the edge of the bottom end of the cover body; the preparation method comprises the following steps: A, powder proportioning; B, uniform stirring and mixing; C, granulation; D, dry pressing molding; E, sintering; and F, post-treatment. According to the invention, the processes of powder proportioning, uniform stirring and mixing, granulation, dry pressing molding, sintering, post-treatment and the like are sequentially carried out according to the set weight components; the ceramic shell which is high in dielectric constant, low in dielectric loss, high in porosity and high in strength is manufactured and used for protecting and packaging a sensor, and thus the anti-interference performance and safety of the sensor during operation are effectively improved.
本发明涉及压电陶瓷技术领域，尤其为传感器封装用陶瓷保护壳体材料、壳体系统及制备方法，其原料组分如下，主料：55%～65%、造孔剂：35%～45%；包括盒体和盖体，所述盒体底部的一侧预留有通槽，所述盒体顶部的边缘位置处开设有两个盲孔，所述盖体位于盒体的上方，且盖体底端的边缘位置处粘接有两个销杆；包括以下步骤：A、粉体配比；B、搅拌混匀；C、造粒；D、干压成型；E、烧结；F、后处理。本发明按照设定的重量组分依次进行粉体配比、搅拌混匀、造粒、干压成型、烧结以及后处理等工艺，制成高介电常数、低介质损耗、高孔隙率且高强度的陶瓷壳体，用于对传感器进行保护封装，从而有效地提高了传感器运行时的抗干扰性及安全性。
