Abstract

The invention relates to composite oxide microcrystalline glass, and an insulating medium slurry and preparation method and application thereof, and belongs to the technical field of thick film circuits. The composite oxide microcrystalline glass is SiO2-B2O3-Cs2O-P2O5-MnO2-Co2O3- Ta2O5-CeO2-Er2O3 composite oxide microcrystalline glass; the insulating medium slurry includes an organic carrier andan inorganic main phase composed of the composite oxide microcrystalline glass. The preparation method of the insulating medium slurry includes: mixing raw materials according to a ratio; heating themixture to 1100-1700 DEG C for 1-24 hours; performing water quenching, drying, and ball milling; mixing the mixture with the organic carrier in proportion; and finally using a three-roll mill to perform rolling repeatedly, and obtaining a thick film circuit insulating medium slurry. The slurry is used for a high-power thick-film circuit insulating dielectric layer of a stainless steel substrate, has a large expansion coefficient, good adhesion, high insulation and resistance, high breakdown voltage, and low leakage current.

Description

technical field [0001] The invention relates to a composite oxide glass-ceramic, an insulating dielectric paste, a preparation method and application thereof, and belongs to the technical field of thick-film circuits. Background technique [0002] Thick-film electronic paste is the main material for preparing thick-film circuits. It is widely used in electronic packaging, interconnection and passive components. With the increase of the power of thick-film circuits, this technology is gradually applied to electric heating elements, especially in high-end Small household appliances such as rice cookers, electric kettles, electric water heaters, electric irons, disinfection cabinets and hairdressing devices, etc. [0003] Thick-film electronic paste is mainly divided into insulating dielectric paste, resistance paste and conductive paste. The insulating dielectric paste is coated on the surface of the substrate to provide an insulating layer. Its basic composition is a glass ph...
