Abstract

The invention discloses a medium slurry with high acid resistance. The glass powder used in the medium slurry is obtained by tempering Bi-Si-B series glass powder at 500-600 DEG C for 20-24 hours; , β-cellulose, etc. to prepare organic carriers; chromium trioxide, cadmium trioxide, titanium dioxide, etc. are added as oxide additives to further enhance the stability of the slurry. The binder phase glass powder used in the medium slurry of the invention adds high temperature tempering on the basis of the traditional water quenching process, which can eliminate the internal stress generated in the process of smelting and ball milling, and further improve the compactness; at the same time, it is used in the preparation process of the organic carrier. Butyraldehyde oxime replaces terpineol, the prepared slurry not only has extremely high acid resistance, but also can ensure stable breakdown voltage and low encapsulation change rate, which can adapt to harsher use environments and prolong its use. It has obvious economic benefits at the same time of life.

Description

technical field [0001] The invention belongs to the technical field of medium slurry, and in particular relates to a medium slurry with high acid resistance. Background technique [0002] For a long time, the acid resistance of the dielectric paste has determined the service life of the substrate after printing and the limitations of the use environment. The existing dielectric paste on the market will be soaked in 5% dilute sulfuric acid after printing, and the surface layer will appear to varying degrees. Shedding phenomenon, lower service life and greater uncertainty. The acid resistance of the dielectric slurry determines its promotion speed. There are two reasons: First, the cost problem: the dielectric slurry is used in various electronic devices such as resistors and filters, and most of the substrate area needs to be covered with the dielectric slurry. In order to achieve the insulation effect. It is urgent to find a kind of dielectric slurry, which can greatly imp...
