Description

The preparation method of piezoelectric ceramics spraying gun medium
Technical field
The present invention relates to a kind of making method of piezoelectric ceramics, relate in particular to a kind of preparation method who is used for the piezoelectric ceramics dieelctric sheet of spraying gun.
Background technology:The piezoelectric ceramics dieelctric sheet is the key element that fragrant water atomizer(-iser) ﹑ adds equipment such as the medical day with fog of wet fog device ﹑, and it is that a thickness is 0.4～0.6 millimeter circular ceramic plate.At present, the piezoelectric ceramics dieelctric sheet adds the dry-pressing formed green sheet of processing of tackiness agent, at last sinter molding in air then usually by the granulation of raw material ball milling.The not only ratio of briquetting of this method is low, energy consumption is high, and the consistence of green compact thickness is difficult to guarantee; In addition, because dry-pressing formed plasticity is relatively poor, so the density of green compact is relatively poor and easy layering, thereby causes the lower and easy fragmentation of product density.
Summary of the invention:In order to overcome the defective that exists in the prior art, the present invention aims to provide a kind of preparation method of electroceramics spraying gun medium, adopts the piezoelectric ceramics dieelctric sheet of manufacturing of the present invention to have the density height, is difficult for characteristics such as broken, that unit for electrical property parameters is stable.
To achieve these goals, the present invention adopts following technical scheme: it is formulated by weight ratio and the tackiness agent of pressing 100:14 through the grog of the following weight part of incinerating: Pb 3O 455.6～76, ZrO 212～24.2, TiO 28～21, Sb 2O 50～6, Nb 2O 50～6, SrCO 30～17, MnO 20～3, ZnO 0～2, La 2O 30～2; Its method is:
1) is that above-mentioned each grog of 0.5～2 millimeter mixes back wet-milling and becomes porcelain with mean particle size, guarantees that the porcelain mean particle size reaches 0.5～2 micron, maximum particle size≤8 micron;
2) above-mentioned porcelain and tackiness agent are mixed, used the roll forming machine rolling then 0.5～1 hour, process porcelain group, old 12 hours;
3) will passing through old porcelain group, to use roll forming machine finish rolling be 0.4～0.6 millimeter diaphragm to thickness;
4) above-mentioned diaphragm is molded into circular medium green compact;
5) above-mentioned medium green compact are fired into the medium ceramics under 1260～1290 ℃ of conditions, are incubated 2～2.5 hours.
Optimal technical scheme of the present invention is: Pb 3O 461～71, ZrO 215～21, TiO 212～17, Sb 2O 52～4, Nb 2O 52～4, SrCO 35～12, MnO 21～2, ZnO 1, La 2O 31.
Further optimal technical scheme of the present invention is: Pb 3O 466, ZrO 218, TiO 214.5, Sb 2O 53, Nb 2O 53, SrCO 313.5, MnO 21.5, ZnO 1, La 2O 31.
Compare with prior art; The present invention is owing to adopted technique scheme; Adopted wet type to roll mill, old and finish rolling operation, therefore not only greatly refinement the granularity of porcelain, thereby improved the plasticity and the density of green compact effectively; Overcome thoroughly that the piezoelectric ceramics dieelctric sheet thick consistency that adopts the traditional method preparation is poor, density is low, defectives such as easy layering and fragmentation, guaranteed the stable of product unit for electrical property parameters; And have ratio of briquetting height, a low power consumption and other advantages.
