High-performance composite dielectric filter, material thereof, and preparation method of material
The invention discloses a high-performance composite dielectric filter, a material thereof, and a preparation method of the material. Ceramic powder, deionized water and a dispersing agent are mixed in proportion, and undergo the working procedures of ball milling, drying, pre-sintering, smashing, secondary grinding, drying, stirring, extrusion injection molding, baking, hot pressing and the like to prepare the high-performance composite dielectric filter material. The powder obtained after the first drying is subjected to 1330 DEG C high temperature pre-sintering, the high temperature sintering is not required during the subsequent preparation process, and the paraffin oil and the coupling agent only need to be volatilized at the temperature of 380 DEG C so as to reduce the industrial energy consumption and the production cost of the material production system, such that the production efficiency of the material production system is improved; and PTFE is added into the material obtained after secondary drying, so that the prepared high-performance composite dielectric filter material has relatively good flexibility, and a component prepared from the high-performance composite dielectric filter material is not prone to cracking in a use process.
本发明公开高性能复合介质滤波器及材料、制备方法，将陶瓷粉料、去离子水、分散剂按比例混合，经过球磨、干燥、预烧、粉碎、二次研磨、干燥、搅拌、挤压注塑、烘烤以及热压等工序，制备出高性能复合介质滤波器材料。通过对第一次干燥后得到的粉料进行1330℃高温预烧，在后续制备过程中无需进行高温烧结，仅需在380℃的温度下，将石蜡油和偶联剂挥发掉，降低材料生产体系的工业能耗和生产成本，从而提高材料生产体系的生产效率；再配合在第二次干燥后得到的物料中加入PTFE，使制得的高性能复合介质滤波器材料具有较好的柔韧性，从而使其所制得的元器件在使用过程中不易开裂。
