3, nontoxic, harmless, the no width of cloth of Ru china shining glaze of the present invention itself is penetrated, and is the novel material and the novel process of environment-friendly type.

Embodiment

Below in conjunction with embodiment Ru china shining glaze of the present invention and preparation technology thereof are described further.

Ru china shining glaze of the present invention is made up of parent glaze and luminescent powder, and wherein said parent glaze is made up of following component by weight percentage: white feldspar 12%～36%, quartz 10%～20%, calcite 0～14%, borax 0～25%, boric acid 0～35%, zircon 0～10%, saltpetre 0～8%, zinc oxide 0～8%, fluorite 0～5%, yellow soda ash 0～7%, Strontium carbonate powder 0～20%, barium carbonate 0～15%, rhombspar 0～5%.

Following table 1 is listed to be prescription and five embodiment of the parent glaze of Ru china shining glaze of the present invention.

Table 1 Ru china shining glaze basestocks prescription (weight %)

In the Ru china shining glaze of the present invention the component and the proportioning thereof of luminous color base of luminescent powder be existing technology, can be prepared by the content that public publication is delivered, also can directly buy from producer.

The prescription of following table 2 a kind of disclosed luminous color base of classifying as.

The prescription of the luminous color base of table 2

The preparation method of this luminescent powder is:

Accurately take by weighing various raw material → mix grindings → calcination → pickling → clear water rinsing → dry → sieve → standby.

Technology point: 1, calcining temperature is 1100 ℃, and high temperature kept 20 minutes, and will carry out in burner hearth; 2, cooling will slowly be carried out, and can not contact with air; 3, rinsing 30% hydrochloric acid; 4, be washed to till the PH7; 5, color base is crossed 180 mesh sieves.

Application number is that 98110318 Chinese patent discloses a kind of luminous color base, adopts novel alkaline earth aluminates phosphors twilight sunset long.

The parent glaze of Ru china shining glaze of the present invention and the weight percent of luminescent powder are: luminescent powder 25%～30%, parent glaze 70%～75%.

The embodiment of preparation method's processing step of Ru china shining glaze of the present invention is as follows:

1. at first the accurate proportioning of parent glaze raw material is stirred and pack in the Cinker clew furnace, melt temperature to 1300 ℃ becomes liquefaction, be poured into again quench in the cold water broken, levigate in the ball mill of then packing into to 200 orders, dry for standby; 2. basestocks that 1. step is made and luminous color base were combined together by 3: 1, and dry grinding is thin to passing through 200 mesh sieves (blue green, yellowish green, orange red proportioning is identical); 3. the glaze that 2. step is made is in harmonious proportion evenly with solvent animal glue, and thickness is suitable for suitable, makes it neither to trickle, and is not thick again to drawing effort; This gelatin another name hide glue, there have bulk also to have to be granular, and market is on sale.It is standby to be dipped to dissolving with the glue of 60% hot water+40% during use; 4. choose your porcelain products (as bottle, extension dish etc.), paint various patterns such as pliosaur, phoenix, birds and flowers with ink, coat blue green, yellowish green or orange-red luminous glaze with the glaze that mixes up by pattern again, thickness is advisable for the 1-2 millimeter; 5. your porcelain products of having painted luminous glaze are packed into and are burnt to 900 ℃ in the kiln, are cooled to room temperature again and take out and get final product (oxidizing atmosphere, reducing atmosphere can).Burned Ru china shining glaze presents the yellow-green colour pattern daytime, presents illumination effects such as orchid is green, yellowish green, purple when evening or dim light.

Be noted that: in the preparation process of luminescent powder, parent glaze, necessarily avoid contacting, turn black otherwise burn the pattern that with iron, not luminous.
