Description
Technical Field
The invention relates to the technical field of electronic material and component processing, in particular to silver paste for a ceramic filter and a preparation method thereof.
Background
The ceramic filter is a frequency-selecting element widely applied to electronic product equipment such as televisions, radios, 5G base stations and the like, and plays a role in stable filtering and anti-interference. The existing ceramic filter is generally prepared by taking ceramic materials such as strontium barium calcium titanate, strontium barium titanate and the like as raw materials, pressing the raw materials into sheets, sintering and molding, grinding and polishing, then comprehensively spraying silver paste, sintering at high temperature, and carrying out direct-current high-voltage polarization.
In the actual manufacturing process, after the filter is sprayed and sintered at high temperature, the silver layer wrapping the substrate is easy to peel or warp, and more seriously, the silver layer may fall off. The main reasons for this phenomenon are: the difference in thermal expansion of the substrate and the silver paste coating causes residual stress, thereby causing the silver layer to scale, crack, and peel off.
Disclosure of Invention
Therefore, it is necessary to provide a silver paste for a ceramic filter, which is sprayed on a barium strontium titanate calcium ceramic filter substrate and then dried quickly, and is not prone to peeling, cracking and warping after sintering, and the silver layer has strong adhesion to the surface of the filter substrate.
The silver paste for the ceramic filter comprises the following raw materials in parts by weight:
the metal microparticles comprise 95-100 wt% of silver microparticles.
According to the silver paste, the components of the paste are improved, the inorganic additive and the glass powder are added, so that the thermal expansion difference between the base material and the silver paste coating is reduced, the peeling or warping is not easy to occur during high-temperature sintering, and the welding resistance of the product is improved; the bonding strength of the silver layer and the surface of the filter substrate is improved by adjusting the composition and the addition amount of the glass powder; the silver paste contains high-concentration silver, the viscosity of the silver paste can be kept at a lower level after the silver paste is blended by an organic solvent, the silver paste has better fluidity, and the silver paste can be quickly dried after being sprayed on a filter substrate, so that the time required by a preparation process is reduced, and the silver paste is stable in dispersibility and difficult to layer after being placed for a long time.
In one embodiment, the metal microparticles include silver microparticles and other metal microparticles selected from the group consisting of: one or more of gold microparticles, copper microparticles, nickel microparticles, palladium microparticles, platinum microparticles, and alloy microparticles of any combination of silver, gold, copper, nickel, palladium, and platinum.
Preferably, the metal microparticles are a mixture of silver microparticles and nickel microparticles, wherein the mass ratio of the silver microparticles to the nickel microparticles is 73: (0.01-0.1). More preferably, the mass ratio of the fine silver particles to the fine nickel particles is 73: 0.05.
in one embodiment, the metal microparticles have a particle size of 0.8 μm to 1.78 μm.
In one embodiment, the resin is selected from: one or more of ethyl cellulose, polycarbonate resin, phenolic resin, epoxy resin and acrylic resin.
Preferably, the resin is a mixture of ethyl cellulose and acrylic resin, and the mass ratio of the ethyl cellulose to the acrylic resin is 2: (1-2). More preferably, the mass ratio of the ethyl cellulose to the acrylic resin is 2: 1.5.
in one embodiment, the glass frit is selected from the group consisting of: CaO, MgO, Al2O3、SiO2、CaF2、Sb2O3、Na2O、K2O、Fe2O3、TiO2One or more than two of them.
Preferably, the glass powder is CaO, MgO, Al2O3、SiO2、CaF2、Sb2O3、Na2O、K2O、Fe2O3、TiO2The mixture comprises the following components in the sequence by mass ratio of (12-16): (8-12): (8-12): (40-50): (5-6): (0.5-1.5): (2-4): (1.5-2.5): (2-15): (0-2).

The inorganic additive and the glass powder both contain silicon dioxide, and the addition of a proper amount of silicon dioxide can effectively improve the surface aging characteristic of the silver layer. The solder contains tin, and may migrate through silver grain boundaries to attack the glass interface formed by the glass frit between the circuit portion and the insulator portion, thereby destroying the glass structure and contributing to the aging characteristics. And the addition of silica can suppress tin migration, thereby effectively improving aging characteristics.
The copper oxide and the glass powder in the inorganic additive can improve the bonding strength between the silver layer and the filter under the synergistic action of the copper oxide and the glass powder. The glass frit establishes a bonding structure between the silver layer and the substrate, in which the copper oxide is dispersed, ensuring that the bonding structure between the silver layer and the substrate is not damaged when the product is subjected to mechanical or thermal action.
The growth of silver particles starts from a low-temperature region of 200-300 ℃, the base material is made of ceramics with a softening point not lower than 500 ℃, so that the sintering shrinkage of the silver and the base material is not matched, and the addition of a proper amount of molybdenum powder and tungsten powder can reduce the sintering shrinkage difference of the silver layer and the base material, thereby effectively reducing the peeling and warping of the silver layer.
