Abstract
The invention discloses a preparation method of a glass phase in a high power resistor. The preparation method comprises the steps of: (1) putting silica, calcium oxide, aluminum oxide, bismuth trioxide and barium oxide into a mixer for mixing, and then putting the mixture into a heating furnace to perform baking; (2) cooling the mixture, then adding ethanol of equal mass, placing the obtained mixture into a rod mill to conduct grinding, then performing pumping filtration, and putting the product into a heating furnace to perform baking; (3) cooling the mixture, adding water of equal mass, putting the substances into a ball mill to conduct grinding, then placing the product into a heating furnace for drying; and (4) adding the prepared glass powder into a resistor paste and performing mixing, thus obtaining the glass phase. The method provided by the invention adopts two-stage grinding, and adds a baking process before grinding, through interpenetration of the components during grinding, the prepared glass phase has good homogeneity and fine particle size.
Description
Technical field
The present invention relates to resistance slurry preparing technical field, the preparation side of glass phase in particularly a kind of high-power resistance
Method.
Background technology
High-power thick-film resistance is to rely on interparticle contact in glass basis to form resistance, and its cost is relatively low, frequency response speed
Degree is fast, is used widely in non-precision appliance applications.Contact in thick-film resistor constitutes complete resistance, but the heat in work
Strain can be interrupted contacting.Due to parallel connection in most cases, thick-film resistor will not be opened a way, but resistance can be held with temperature over time
Continuous increase.
Glass mutually finally becomes the quality of phase in resistance system, is heavily dependent on preparation technology.
Content of the invention
The invention aims to providing a kind of preparation method of glass phase in high-power resistance.
For achieving the above object, the invention discloses in a kind of high-power resistance glass phase preparation method, by weight
Number takes silicon dioxide 30, calcium oxide 20, aluminium oxide 20, bismuth oxide 15, Barium monoxide 10, and its concrete preparation process is：
（1）Silicon dioxide, calcium oxide, aluminium oxide, bismuth oxide, Barium monoxide are inserted mixing 20-30 minute in mixer, then
Insert at 240-300 DEG C, in heating furnace, toast 60-70 minute；
（2）By step（1）After middle compound cooling, the ethanol of the quality such as addition, insert grinding 5-7 hour in rod mill, grind
Sucking filtration afterwards, then insert in heating furnace and to toast 20-30 minute at 240-300 DEG C；
（3）By step（2）After middle compound cooling, the water of the quality such as addition, insert grinding in ball grinder 24-29 hour, grind
After insert in heating furnace 140-160 DEG C dry；
（4）By step（3）It is mixed to get glass phase in the glass dust addition resistance slurry preparing.
Advantages of the present invention and good effect are：
The inventive method employs two-period form and grinds, and adds baking process before the milling, oozes mutually beneficial to each component when grinding
Thoroughly, the glass phase homogeneity of preparation is good, and granularity is thinner.
