Abstract

The present invention relates to a process for preparing enamel electroluminescent layer, and is characterized by that firstly, the luminous body medium powder in the electroluminescent layer is prepared, and is made up by using oxides of silicon, boron, barium, strontium, titanium, calcium, zinc, potassium, sodium and magnesium according to a certain weight percentage. Then uniformly mixing them, using alcohol-containing lipid and volatile oil to make them into proper viscosity, adopting screen printing method to print it on the pattern-transferring film according to the required pattern or character form, when it is required to make it, transferring the luminophor on the pattern-transferring film onto the made enamel screen biscuit, drying and firing so as to obtain the invented product.

Description

Technology for making electroluminescence layer of enamel

The present invention relates to the manufacture craft of electroluminescence Application Areas, particularly electroluminescence layer of enamel.

The manufacturing process of electroluminescence body in the past, be pure luminescent powder and medium powder prepared in proportion after, be formulated to proper viscosity with distilled water and spray.This method waste is very big, the cost height, and when using simultaneously, luminosity is difficult to again evenly, and when enamel is fired, fires the manufacture craft of electroluminescent layer, still belongs to initiative both at home and abroad.

The novel manufacture craft that the purpose of this invention is to provide a kind of electroluminescence layer of enamel.

The present invention finishes as follows: at first prepare electroluminescent layer, form by the luminophor medium powder, its prescription is made up of silicon (Si), boron (B), barium (Ba), strontium (Sr), titanium (Ti), calcium (Ca), zinc (Zn), potassium (K), sodium (Na), magnesium oxide compounds such as (Ma), and its weight percent is by following scope: SiO ₂6～16, B ₂O ₃15～35, BaO0.01～15, SrO0.01～7, TiO ₂0.01～3.5, CaO0.01～2, K ₂O0.01～6, Na ₂O0.01～12, MgO0.01～2, ZnO8～25.Carry out evenly mixed, then with containing pure lipid and volatile oil is deployed into proper viscosity, as printing-ink, utilizing the screen printing method that it is printed on required pattern or literal shape moves on the colored film, when making electroluminescence layer of enamel, the twinkler that moves on the colored film is transferred on the enamel screen blank of making in advance, wait its drying after, fire and form through 700 ℃～730 ℃ heating.

The present invention is formulated to the manufacture craft that proper viscosity sprays with distilled water after preparing in proportion than it former pure luminescent powder and medium powder, and can reduce cost reaches 60%, and cuts the waste significantly; The luminosity of electroluminescent layer is also much more even than in the past.

Further specify below in conjunction with accompanying drawing.

Fig. 1 is the colored membrane structure figure that moves among the present invention.

With reference to Fig. 1, be applied in the manufacture craft of electroluminescence layer of enamel and move colored membrane process, the structure of moving colored film by enamelled paper (1), oil membrane (2), twinkler film (3), contain pure adipose membrane (4) and form.Enamelled paper (1) also can be general label paper.Twinkler film (3) is to adopt silk screen print method that twinkler is printed on the oil membrane (2) with pattern or literal shape, and oil membrane (2) is exactly the easy volatile grease, be attached on the enamelled paper (1), and then the spraying last layer contains pure adipose membrane (4).When needing to make electroluminescence layer of enamel, as long as be immersed in the water moving colored film, cross several minutes, can tear with the oil membrane (2) of twinkler, it is attached on the enamel biscuit, fired forming, firing temperature is the same when making with general enamel, the just foregoing luminophor medium powder of twinkler film (3) is deployed into the same viscosity of printing ink with containing pure lipid with volatile oil herein, print required pattern and literal shape with the screen printing method, dry back the thin film shape, move colored membrane process and be the part in the electroluminescence layer of enamel integrated artistic, part can be prepared, the making electroluminescence layer of enamel can be taken out when needing.

Claims

1, the manufacture craft of electroluminescence layer of enamel is characterized in that:

A, at first prepare luminophor medium powder in the electroluminescent layer, its weight percent of filling a prescription is by following scope: SiO ₂6～16, B ₂O ₃15～35, BaO0.01～15, SrO0.01～7, TiO ₂0.01～3.5, CaO0.01～2, K ₂O0.01～6, Na ₂O0.01～12, MgO0.01～2, ZnO8～25;

B, the luminophor medium powder for preparing is evenly mixed with containing pure lipid and volatile oil is deployed into proper viscosity, as printing-ink, utilizes silk screen print method that it is printed on required pattern or literal shape and moves on the colored film then;

C, the twinkler that will move on the colored film are transferred on the Manufactured enamel screen blank, and dry after 700 ℃～730 ℃ heating are fired and formed;

D, said move colored film by enamelled paper (1), oil membrane (2), twinkler film (3), contain pure adipose membrane (4) and form, twinkler film (3) is pattern or literal shape, adopt silk screen print method that twinkler is printed on the oil membrane (2), oil membrane (2) is attached on the enamelled paper (1), sprays last layer then and contains pure adipose membrane (4).
