The invention discloses an injection molding binder for preparing dielectric filter ceramic products and its application, comprising a resin component, and the resin component includes a material with a mass ratio of 5-12:1:0.4-2:1-3. Polyoxymethylene, non-polar polymer, polyacrylic resin and ethylene-vinyl acetate copolymer; polyoxymethylene accounts for 50-60% of the binder by mass percentage; and the aforementioned binder is mixed with ceramic powder The prepared feed mixture for preparing dielectric filter ceramic products; and the pellets for preparing dielectric filter ceramic products prepared by extruding and granulating the aforementioned feed mixture; and the dielectric filter ceramic products using the aforementioned pellets , especially 5G dielectric ceramic filters; the present invention can effectively improve the fluidity of feeding materials, increase the solid content of sub-micron ceramic powders, has high degreasing efficiency and fast speed, and is especially suitable for large-size and complex ceramic products such as 5G dielectric ceramic filters device preparation. |
