Embodiment 1

[0030] Example 1: Making light-emitting strips on guide bricks ( figure 1 )

[0031] Its process (dry method) steps are:

[0032] 1) Add frit powder with a fineness of 150 mesh to the phosphor powder with a fineness of 150 mesh, in which the phosphor powder accounts for 75% and the frit powder accounts for 25%, and the two are mixed evenly in proportion to prepare a luminescent powder.

[0033] 2) Use a thin plate to make two bushings with the same shape of the hollow part, and the shape of the hollow part is figure 1 The shape of the light-emitting portion 1 shown is a rectangular bar shape with an arrow. The production method of the leakage plate: press the metal or plastic thin plate with a 1mm drill bit figure 1 The shape of the light-emitting part 1 shown, punch out evenly arranged small holes, so that countless small holes are arranged on the thin plate figure 1 The shape of the luminous part 1 shown, made with figure 1 Leakage plate in the shape of the light-emitti...

Embodiment 2

[0038] Example 2: Making luminous anti-skid bricks ( image 3 )

[0039] Its process (dry method) steps are:

[0040] 1) Add frit powder with a fineness of 150 mesh to the phosphor powder with a fineness of 150 mesh, in which the phosphor powder accounts for 70% and the frit powder accounts for 30%, and the two are mixed evenly in proportion to prepare a luminescent powder.

[0041] 2) Made on the surface of the brick image 3 As shown in the groove, the groove is used as the light-emitting part 1, and the depth of the groove is 5mm.

[0042]3) Fill the luminous powder into the groove with a thickness of 3mm, and this layer is the luminescent layer of the luminous part 1 of the brick. Then, the surface of the luminescent powder is coated with frit powder with a thickness of 1 mm, which is the protective layer of the luminous part 1 of the brick. In this way, the light-emitting part 1 is 1 mm lower than the surface of the brick, which can play an anti-slip effect.

Embodiment 3

[0045] Example 3: Making a luminous pattern on a glass ( Figure 4 )

[0046] Its process (wet method) steps are:

[0047] 1) Mix 20-30 parts of phosphor powder with a fineness of 250 mesh, 3-5 parts of additives, and 65-75 parts of water in proportion to make a luminous glaze.

[0048] Wherein the filler can be dextrin, bone glue, methyl cellulose and the like.

[0049] 2) Take 50-60 parts of frit powder with a fineness of 100 meshes, 0.1-0.3 parts of sodium tripolyphosphate, 3-7 parts of methyl cellulose, 35-38 parts of water, add in a ball mill for internal grinding, Pass through a 150-mesh sieve to make glaze paste.

[0050] 3) in Figure 4 According to the required light-emitting part 1, the required light-emitting pattern is engraved on the surface of the glass cup 4, the depth is 1.5mm, and the light-emitting glaze is drawn into the carved pattern by spraying, hand-painting, etc., so that the thickness of the light-emitting glaze is 0.5mm. This layer is the light-...

Abstract

The technological process of sintering fluorescent powder on the surface of ceramic and glass product may be a dry process or a wet process. The said process can sinter fluorescent powder as one kind of light emitting material to the inner or external surface of ceramic or glass product, and the surface may be in different shapes, planar, curved, etc. The light emitting product thus produced has high light emitting strength, long light emitting time, no toxic side effect and no radioactivity, and may be tableware, drinking vessel, tea set and other daily life article.

Description

technical field [0001] The invention relates to a process method for sintering luminescent materials on products, in particular to a process method for sintering fluorescent powders on the surfaces of ceramic and glass products. Background technique [0002] Phosphor powder, a luminescent material, is widely used in many fields to make various luminescent products. For example, it can be used to make luminous clocks, instruments, etc., and emergency lights for emergency lighting. In the existing technology of using fluorescent powder as luminescent material to make luminescent products, the fluorescent powder is usually added to the resin and coated on the surface of the product, or a layer of transparent plastic film is pasted on the surface coated with the fluorescent powder. Protective layer, because the luminescent products made by this method are completed at room temperature, its surface hardness is low, it is not resistant to abrasion, high temperature, poor anti-agi...
