Detailed Description
Preferred embodiments of the present invention are described in further detail below.
A conductive material for induction heating of a ceramic substrate comprises silver powder, a flux and varnish, wherein the varnish is a mixture containing a butyl acrylate compound or copolymer, a plasticizer and an aromatic solvent. The ink mixing oil comprises the following components in percentage by mass: 70-75% of butyl acrylate compound or copolymer, 8-10% of plasticizer and 15-20% of aromatic solvent. The butyl acrylate compound or the copolymer comprises at least one of isobutyl methacrylate and butyl methacrylate-MMA copolymer. The plasticizer is diisopropyl 1, 2-cyclohexanedicarboxylic acid, dibenzoate compounds or semicarbazide compounds. The aromatic hydrocarbon solvent is one or a mixture of more than two of toluene, xylene, trimethylbenzene, tetralin and cumene.
Of the above-mentioned conductive materials, a mixture of a flux used as glass frit and silver powder is used to produce these conductive coatings, which are mixed in an organic solvent to form a self-adhesive, flexible, transfer layer, which is covered on an interleaf paper composed of a release layer and a transfer layer. The glass frit, known as flux, is composed mainly of oxides of barium, aluminum, silicon, lithium and sodium. The silver powder has a particle size distribution in the range of 0.1 to 2.9 μm. The powder is mixed with flux to form a paste, which may be in a proportion of 70% silver to 30% flux by weight. Organic varnish is added to the paste to produce an ink for producing a transfer layer of uniform thickness. The silver powder is included in a flux and varnish in such a way that the overall proportion of silver is 35-40%, and after firing, the film exhibits a glass-glossy surface when cooled, containing silver particles.
The fluxing agent comprises the following components in percentage by mass: SiO 22 6-55%，Bi2O3 42-45%，Al2O3 1-12% ，B2O316-35%, ZnO 20-45%, and other metal oxide 1-12%, wherein the other metal oxide comprises Li2O、Na2O、K2O、SnO2、ZrO 2At least one of BaO and CaO. The flux of the above composition provides a low coefficient of thermal expansion flux that can be used to make a flux suitable for enamel and also for ceramic tableware decoration without increasing the maturation temperature of the enamel.
In addition, the above flux composition has a low coefficient of thermal expansion on glaze, is suitable for a lead-free and cadmium-free glaze surface, and has a coefficient of thermal expansion in the range of 4.0 to 7.0X 10-6V. C. Further, the coefficient of thermal expansion is in the range of 5.0 to 6.0X 10-6/DEG C, and the softening temperature by expansion measurement is in the range of 400 to 600 ℃.
The flux may be formed by mixing the materials together, charging the mixture of materials into a glass furnace through a sufficiently high temperature to produce molten glass, and then cooling the glass by pouring it into water or rolling it through water. It may be preferred to carry out the melting and sintering operations in an oxidizing atmosphere, or to add oxygen-rich components to the molten and melted mixture. The frit may be ground to a powder using conventional grinding techniques. Further, the flux is preferably used in combination with silver powder on a ceramic material, particularly a low-expansion porcelain.
Those skilled in the art will appreciate that glass compositions, when used as fluxing agents, must mature at temperatures below the melting temperature of the glaze on the ceramic articles to which they are to be applied, or produce a smooth, continuous surface. Typically, the above-mentioned fluxing agent will melt at a temperature below 1150 ℃, preferably at a temperature of 900-1100 ℃.
In order to produce conductive inks suitable for screen printing, the composition for decoration additionally contains organic varnish.
The heating plate is composed of a magnetic induction coil operating at an intermediate frequency of 20 to 45 kHz. The transferred film after sintering at about 820 ℃ on the surface of the hot plate yielded a thickness of about 15 +/-3 μm. These initially deposited fired layers were tested for heating performance on a induction plate. The ceramic plate had a diameter of 140 mm and a thickness of 5 mm. It is placed on the sensing plate so that the film is facing upwards. This gives that the coupling distance between the film and the induction coil used under practical conditions (about 11 mm) is the same as the distance between the heating coil and the film. The heating plate may measure the surface temperature using thermocouples connected at equal distances.
The silver powder used for the conductive material was a high purity (> 99.9%) chemically precipitated spherical silver powder. The particle size distribution of the silver powder was D90 (< 2.5 microns), D50 (< 0.95 microns), D10 (< 0.1 microns). The particle diameter refers to the average diameter of the metal particles as determined by TEM (transmission electron microscope) or other suitable method. The conductivity of the end conductive member formed using the paste conductive material varies depending on the intended use. The paste conductive material may be formed using any suitable mixing technique, and the silver powder, ceramic flux, and varnish may be mixed in any order or simultaneously.
The paste conductive material herein may be used to form conductive features on a substrate, such as depositing the paste conductive material onto a substrate and heating the deposited composition to about 580 ℃ and 820 ℃ for a glass substrate for a ceramic substrate to form conductive features on the substrate. Among the deposition methods, screen printing has proven to be a useful technique for application on glass or ceramic substrates. The thickness of the deposit deposition ranges from about 5 nm to about 10 nm. After deposition, the deposited composition was heated to 820 ℃ over a 1 hour heating period and incubated on the ceramic for 10-15 minutes. The deposited paste layer may be electrically insulating or have very low electrical conductivity prior to heating, but heating produces an electrically conductive layer.
