The present invention relates to a method of manufacturing a photoluminescent enamel sign, and more particularly, to further improve the utility model registration No. 0319954, which is the applicant's pre-registered design, the base surface is a photoluminescent enamel, the pattern surface is a non-luminescent enamel It relates to a method of manufacturing the formed photoluminescent enamel signs.

Since the enamel is made by applying inorganic glass on a steel plate or metal plate and baking it, it has excellent durability, fire resistance, and heat resistance, and is beautiful and clean, so it is generally used as a kitchen or test container. Strong characteristics make it a suitable material for general signs. However, there is a problem that a separate lighting facility should be provided at night or in a dark situation. In addition, fire protection facilities, safety information signs or warning signs for the prevention of safety accidents and various induction signs should be prepared by putting a non-luminescent pattern on the surface having the characteristics of the photoluminescent property so that they can be easily seen even in a dark environment. Is not available despite its many advantages. In particular, in a firefighting facility, the induction facility must be able to perform its function for a predetermined time even in the event of a power failure, so the performance of the photoluminescence is required.

Therefore, in order to solve the above problems, the applicant has already applied for utility model registration No. 0319954. The contents of the utility model includes a photoluminescent enamel sign formed by mixing the enamel glaze and the photoluminescent pigment to form a photoluminescent glaze, and expressing a pattern with the photoluminescent glaze on the surface of the enameled plate; The surface of the enameled sheet was coated with the photoluminescent glaze, and the pattern of the photoluminescent glaze was expressed and then fired, but there was a limitation that the manufacturing method was not specific and systematic.

Accordingly, the present invention is to further improve the utility model registration No. 0319954 filed by the present applicant, to provide a more specific and systematic method of manufacturing a photoluminescent enamel sign that a non-luminescent pattern is formed on the photoluminescent surface.

Hereinafter, with reference to the accompanying drawings will be described the present invention for achieving the above object. In the accompanying drawings, it should be noted that reference numerals denoted in processes may use the same reference numerals as much as possible when referring to the same processes in other drawings. In addition, repeated descriptions have been omitted, and in the case where it is determined that detailed descriptions of related well-known processes may unnecessarily obscure the subject matter of the present invention, detailed descriptions thereof will be omitted.

(P140) the photoluminescent enamel layer 40 is formed by uniformly applying the photoluminescent glaze formed by mixing 100 parts by weight of the enamel transparent glaze and 20 to 70 parts by weight of the photoluminescent pigment on the surface of the enamel layer 30. Drying process;

(P150) baking the photoluminescent enamel layer 40 coated with the photoluminescent glaze in a firing furnace;

(P160) forming a non-luminescent glyph layer 50 by attaching letters, numbers, symbols, diagrams, figures, etc. to the surface of the fired photoluminescent enamel layer 40 with a non-luminescent enamel glaze transfer paper;

(P170) the step of firing the non-axis light glyph layer 50 in a firing furnace;

In the manufacturing method, the firing temperature is differently applied depending on the type of the plate 10 so that it is preferably baked for 4 to 6 minutes at 800-920 ° C. for the steel sheet and 520-560 ° C. for the aluminum plate. If it is out of the time range, the glaze and the combination of the plate may not be good or the plate may not maintain the shape. The plate is used after the surface is pretreated with sulfuric acid, and the numerous pinholes formed in this process strengthen the close contact with the oil. However, in the case of a plate surface-treated to be suitable for enamel, the pretreatment step can be omitted.

The lower oil uses enamel lower oil containing the ingredients of adhesive such as cobalt oxide to help the adhesion with the plate.If the enamel layer is too thin or thick, it may not be in close contact with the plate or cracks may occur in the enamel layer. Since it is possible to form the enamel layer in the thickness of 80-120㎛. The oil is enameled oil containing titanium oxide whitening agent to visually block the oil layer. If the enamel layer is too thin or too thick, the oil layer may be exposed or crack may occur. It is preferable to form an enamel layer in thickness.

In the present invention, the transparent glaze mixed in the photoluminescent glaze is 45-55 wt% SiO ₂ , 15-20 wt% Na ₂ O, 10-20 wt% B ₂ O ₃ , 1-5 wt% K ₂ O, 2-5 wt% TiO ₂ , 3-5 wt% ZnO, 2-6 wt% Li ₂ O, 2-6 wt% ZrO ₂ , 5-10 wt% Al ₂ O ₃ It is easy to manufacture by selecting a glaze having a low light melting point, such as glaze is good. In addition, photoluminescent pigments are (SrO) (MgO) _0.1 Al ₂ O ₃ (EuO, Dy ₂ O ₃ ) _0.01 B ₀ , A ₂ O ₃ SrO ₃ B ₂ O ₃ It is preferable to use what consists of compounds which are excellent in heat resistance. In the photoluminescent glaze, if the amount of the photoluminescent pigment is small, the photoluminescent effect cannot be properly produced, and if the amount of the photoluminescent glaze is high, the cost increases. When the glaze is manufactured and used for general use, the photoluminescent enamel layer is formed to a thickness of 80-120㎛ to solve the problem of photoluminescent effect and cost at the same time.

The enamel glaze transfer paper contains an opaque pigment, so that the non-luminescent glyph layer can be contrasted with the photoluminescent enamel layer, and forms a non-glowing glyph layer with a thickness of 80-120 μm.
