Accompanying drawing explanation
Fig. 1 be optimize before and after heat before and after glass dust is comprehensive analyzes.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with the present invention.
A kind of manufacture method of zinc oxide varistor silver slurry glass dust,
Glass dust formula:
| Components Name | Component ratio (Wt%) |
| Bi2O3 | 70 |
| B2O3 | 14 |
| SiO2 | 4 |
| ZnO | 8 |
| Al2O3 | 2 |
| Cr2O3 | 2 |
By optimizing glass powder formula, the oxide of refining glass dust is weighed, after mix homogeneously, puts into aluminium oxide
In crucible, being refined by Muffle furnace, smelting temperature is 1150 DEG C, be incubated 30min, melting terminate after by melten glass liquid through water
After quenching, pulverizing, carry out rolling ball milling 48h by ball, material, alcohol quality than for 3:1:2, after ball milling terminates, by glass paste through 400 mesh
In convulsion baking oven, at 75 DEG C, dry 3h after filter-cloth filtering, after drying, use powder beater slurry glass dust to break up；By glass softening point
Be reduced to about 500 DEG C, reduce volatile component within 680 DEG C simultaneously, make glass in the range of 500 DEG C-680 DEG C stable with
Molten state exists；This glass that can use in the range of 500 DEG C-680 DEG C wide, can meet different firing temperatures, makes to own
Silver slurry has preferably Technological adaptability.
Embodiment 1
(1) refining glass dust 500g, makes process: weighed by the oxide of refining glass dust, put in crucible, stirring
Uniformly, quenched by the refining of Muffle furnace high temperature, shrend, powder, ball milling, filtration, after baking operation, analyze its hot overall characteristic.
(2) take again and test the same working condition, amplifying volume of production refining glass dust 2kg, the most further
Demonstrate the hot overall characteristic of glass dust.
Before and after many experiments, optimization, the comprehensive analysis of heat before and after glass dust is as it is shown in figure 1, as seen from the figure, before optimization
Glass dust is differential thermal curve extremely unstable in the range of 520 DEG C-600 DEG C, has many places heat release endothermic peak, and this shows the slurry prepared
Foaming, silver layer problems of crack may be caused by these heat absorption heat releases in this range, and decrease the attached of silver layer and substrate
Put forth effort；After optimization, glass is without mass loss in the range of 500 DEG C-680 DEG C, and the most non-volatile composition volatilizees, it was demonstrated that prepared by this formula
Glass formed stable glass network structure, not free single-component substance；This is understood by differential thermal analysis
Glass produces endothermic peak at 480 DEG C, it was demonstrated that when 480 DEG C, glass starts to soften, and in the range of 500 DEG C-680 DEG C, differential thermal curve is put down
