Problems solved by technology

When these organic mixtures are used to granulate iron-sealed glass powder, we find that the strength of the granulated powder is not good enough, and the pressed glass body is easily broken
In addition, the patent did not indicate the molecular weight of the organic matter used, nor did it mention what dispersant, defoamer, etc. should be added, nor did it disclose how to add a water-insoluble or slightly water-soluble release agent to the water-based in glass paste

Abstract

The invention provides iron seal glass powder slurry and a preparation method thereof. The iron seal glass powder slurry is prepared from, by mass, 30-60% of deionized water, 34-65% of glass raw powder, 0.25-5% of binder, 0.05-1% of dispersant, 0.01-1% of a releasing agent, 0-0.025% of an antifoaming agent and the like. The preparation method of the slurry comprises the steps of dispersing the glass raw powder obtained after ball milling into the deionized water, and then adding organic matter including the binder, the dispersant, the releasing agent, the antifoaming agent and the like according to a certain sequence while stirring is conducted. The iron seal glass powder slurry has a good rheological property, the added organic matter is nontoxic, volatile, easy to remove and good in environmental protection performance, and iron seal glass granulation powder good in processing property can be obtained.

Description

technical field [0001] The invention belongs to the technical field of sealing glass powder granulation, in particular to the granulation process of iron-sealed glass powder with high glass softening temperature, and specifically relates to the water-based slurry of iron-sealed glass powder required by spray drying granulation technology System configuration and its application to iron-sealed glass granulation powder. Background technique [0002] Iron sealing glass has important applications in refrigeration equipment, relays, lithium batteries and other fields, and is used for electrical insulation and airtight sealing of terminal blocks. The sealing glass preform is usually used in the sealing process, which is formed by pressing, debinding and sintering with granulated powder. Granulating powder is a key step in the production of sealed glass preforms, which is obtained by spray drying the slurry prepared from glass raw powder. There are strict requirements for glass g...
