Problems solved by technology

However, the following problem has been found: when the coating paste containing the solvent composition is coated and dried under normal pressure heat, the polyvinyl acetal resin will be used as the binder resin due to prolonged heating. The coated sheet softens and deforms
However, n-octanol has solubility in high-molecular-weight polyvinyl butyral resin used in green sheets, and the sheet erosion resistance is not sufficient

Abstract

The present invention provides a solvent composition for manufacturing laminated ceramic parts. The solvent composition can be used for bringing performances of ethyecellulose and other adhesive of adhesive resin into full play, erosion phenomenon of the laminated ceramic parts is not easy to occur during the manufacturing process, evaporation and drying can be realized easily, and the coherent fitting with a coated cloth sheet is excellent. The solvent composition for manufacturing the laminated ceramic parts comprises solvent A with a boiling point below 206 DEG C and a solvent B with a boiling point above that of the solvent A. In the solvent A, the solubility of a low polarity polyvinyl butyral resin is above 5g / 100g in 25 DEG C, the solubility of ethyecellulose comprising 45.0 to 53.0 mo 1% ethyoxyl is above 5g / 100g in 25 DEG C, and in the solvent B, the solubility of a high polarity polyvinyl butyral resin is below 5g / 100g in 25 DEG C.

Description

technical field [0001] The invention relates to a solvent composition for manufacturing laminated ceramic parts. The solvent composition can fully exert the adhesive properties of binder resins such as ethyl cellulose, and is not easy to be used in the manufacturing process of laminated ceramic parts. A sheet erosion phenomenon occurs in the middle, and evaporative drying is easy to perform, and the adhesion to the coated sheet is excellent. Background technique [0002] Laminated ceramic parts include capacitors, inductors, varistors, thermistors, speakers, drivers, antennas, solid oxide fuel cells (SOFC), etc., and are made by laminating thin layers of ceramic layers and conductive layers. Capacitors, inductors, varistors, thermistors, speakers, drivers, and antennas are mainly components that laminate ceramic layers and conductor layers, and solid oxide fuel cells (SOFC) are mainly components that laminate multiple ceramic layers. [0003] As a lamination method, it can ...
