Long afterglow luminous anti-skid marking tile

Abstract

The long-afterglow luminescent anti-slip marking tile comprises, from bottom to top, a base layer, a white reflective glaze layer, a long-afterglow luminescent layer, and a transparent glaze layer. A portion of the upper surface of the transparent glaze layer features a glaze marking layer of a different color from the long-afterglow luminescent layer, forming a light-shielding, color-revealing graphic area. The remaining areas of the transparent glaze layer without the glaze marking layer form a light-transmitting luminescent area. An anti-slip structural layer is located on the upper surface of the glaze marking layer. This anti-slip structural layer is either a transparent or semi-transparent anti-slip light-transmitting structural layer one, or / and an anti-slip light-shielding structural layer two of the same color as the glaze marking layer, forming a light-transmitting anti-slip structural layer with a rough, uneven surface. All layers are sintered at medium temperature to create a highly recognizable multi-layered inorganic anti-slip marking tile with a high degree of visual identification. Visual identification in the bright field is achieved through the color difference between the light-shielding, color-revealing graphic area and the light-transmitting luminescent area, while in the dark field, visual identification is achieved through the contrast of brightness between the light-shielding, color-revealing graphic area and the light-transmitting luminescent area.

Description

Technical Field

[0001] This utility model belongs to the field of luminescent signage technology, specifically relating to a long-afterglow luminescent anti-slip signage ceramic tile. Background Technology

[0002] Long-afterglow luminescent ceramic tiles (also called glow-in-the-dark ceramic tiles) are a new type of ceramic tile made by incorporating long-afterglow luminescent materials into the glaze and firing it. Due to their energy-storing and self-luminous properties, they are popular in the market and can be used indoors or outdoors. Currently, they are mainly used in emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, and landscaping, and are particularly suitable for laying on the ground as emergency signs and fire escape markers. Existing long-afterglow luminescent ceramic tiles generally have the following main drawbacks:

[0003] 1. Due to the limitations of existing material technology, only aluminate matrix luminescent ceramic bricks have a relatively good luminescent effect, but their material color is limited, resulting in a single body color of the fired bricks, which is mostly pale yellow.

[0004] 2. To achieve the desired luminescence effect, existing long-afterglow luminescent ceramic tiles often have a layer of transparent glaze on their upper surface. However, due to limitations in the firing process and performance characteristics of the glaze, their anti-slip function is poor.

[0005] 3. Some long-afterglow luminescent ceramic tiles use light-curing printing to directly print patterns onto the surface of the fired ceramic tiles in order to achieve the desired pattern and color effects. Although this method is low-cost and flexible, it is not wear-resistant and is prone to discoloration when used outdoors, which limits the product's applications and makes it particularly unsuitable for ground use.

[0006] 4. Some people use mechanical processing such as cutting and milling to drill holes or grooves on the surface of ceramic tiles, and then use adhesives (usually glues) to combine with pigments or colorants to fill, scrape or pour into the non-penetrating holes, grooves or depressions in the form of color stripes or blocks of different body colors, such as "a kind of reprocessed luminescent ceramic tile" in patent number 202020386732.X. While it can achieve the effect of pattern color contrast, it requires secondary processing, the process is complicated and the production cost is high.

[0007] In summary, existing long-afterglow luminescent ceramic tiles generally suffer from many problems such as monotonous body color, low recognizability, poor anti-slip performance, and poor wear resistance. Solving these problems has become an urgent task for the industry. Utility Model Content

[0008] This long-afterglow luminescent ceramic tile belongs to the security field. Its process, materials, and functions differ from ordinary building ceramic tiles in many ways. The structure of ordinary building ceramic tiles is not suitable for the structure of long-afterglow luminescent ceramic tiles used in security applications. To address the above problems, the technical problem to be solved by this utility model is to provide a long-afterglow luminescent anti-slip marking tile with clear and durable patterns. In bright fields (i.e., high illuminance environments), visual identification is mainly achieved through the color contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark fields (i.e., low illuminance environments), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). It has high recognition, good anti-slip performance, and is not prone to dust accumulation.

[0009] The main features of this utility model are as follows:

[0010] 1. Adding an anti-slip structural layer of the same color as the enamel marking layer to the enamel marking layer can enhance its anti-slip effect and make the graphic information clearer. Alternatively, a transparent or semi-transparent anti-slip structural layer can be added to the enamel marking layer to enhance its anti-slip effect. In addition, the color contrast between the light-blocking color-revealing graphic area (S) and the light-transmitting luminous area (P) in bright field (high illumination environment) is obvious, resulting in high recognition and better transmission of marking information. This is more suitable for use in the security field.

[0011] 2. A transparent or semi-transparent anti-slip structural layer can be set in local areas on the transparent glaze layer to further increase the area ratio of the anti-slip structural layer and enhance the anti-slip effect;

[0012] 3. The smoothness of the transparent glaze layer without anti-slip structure layer is high. Its surface is not easily affected by the accumulation of foreign objects such as dirt and dust, which will affect the luminous brightness of the long afterglow luminous layer. It not only ensures the luminous effect, but also makes the contrast between the light-blocking color-printing area (S) and the light-transmitting luminous area (P) in the dark field (low illumination environment) obvious, with high recognition. It is also easy to clean, and its luminous brightness will not be affected even after long-term use.

[0013] The advantages of this utility model are: it has high recognition in both bright and dark fields, and can provide high-brightness long afterglow luminous indication and guidance functions. Moreover, through the reasonable setting of the anti-slip structure layer area, it has both good anti-slip function (areas with anti-slip structure layer) and is not easy to accumulate dust (areas without anti-slip structure layer). It can be applied in places with high traffic and has extremely high practical value.

[0014] The specific technical solution of this utility model is: a long-afterglow luminescent anti-slip marking ceramic tile, which, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3) (luminescent layer), and a transparent glaze layer (4) (to prevent the surface from being affected by the deposition of foreign matter such as dirt and dust, which would affect the luminescence brightness of the long-afterglow luminescent layer).

[0015] A local area on the upper surface of the transparent glaze layer (4) is provided with a glaze marking layer (5) of a different color from the long afterglow luminescent layer (3) (color development, light blocking) (optional wet glaze printing, dry glaze printing, glaze inkjet printing, preferably wet glaze printing) to form a light-blocking and color-developing graphic area (S). The remaining area on the transparent glaze layer (4) without the glaze marking layer (5) forms a light-transmitting luminescent area (P). The upper surface of the glaze marking layer (5) is provided with an anti-slip structural layer (6).

[0016] The anti-slip structural layer (6) is a transparent or semi-transparent anti-slip and light-transmitting (transparent or semi-transparent) structural layer one (6-1), or / and an anti-slip and light-shielding structural layer two (6-2) of the same color as the glaze marking layer (5) (to give the glaze marking layer an anti-slip effect and make the graphic information clearer). The anti-slip and light-transmitting structural layer one (6-1) is a light-transmitting anti-slip structural layer whose bottom surface is sintered with the top surface of the glaze marking layer (5), and whose top surface forms a surface roughness (granular texture) with an uneven anti-slip structure. The surface roughness (coefficient of friction) of the area where (6-1) is located is greater than the surface roughness (coefficient of friction) of the area where the anti-slip and light-transmitting structure layer 1 (6-1) is not provided. The anti-slip and light-shielding structure layer 2 (6-2) is formed by sintering its bottom surface and the top surface of the glaze marking layer (5) together, and the top surface of the anti-slip and light-shielding structure layer 2 (6-2) forms an anti-slip structure layer with a rough and uneven anti-slip structure. The surface roughness (coefficient of friction) of the area where the anti-slip and light-shielding structure layer 2 (6-2) is located is greater than the surface roughness (coefficient of friction) of the area where the anti-slip and light-shielding structure layer 2 (6-2) is not provided.

[0017] The aforementioned base layer (1), white reflective glaze layer (2), long afterglow luminescent layer (3), transparent glaze layer (4), printed glaze marking layer (5), and anti-slip structural layer (6) form an inorganic multi-layer structure (generally sintered in stages) anti-slip marking ceramic tile with high recognition. It is formed by medium-temperature sintering at temperatures above 500℃. In bright field (high illuminance environment), visual recognition is mainly achieved through the color contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark field (low illuminance environment), visual recognition is mainly achieved through the contrast between the light and dark of the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P).

[0032] Alternatively, the second anti-slip and light-shielding structural layer (6-2) is a granular light-shielding and anti-slip layer with multiple flashing points formed by sintering opaque glaze dry granules mixed with inorganic reflective particles with reflective function (generally using a stencil printing process), thereby indicating that the tile has dual functions of luminescence and reflective flashing, which can improve the recognizability of the tile.

[0073] Example 1

[0074] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 1 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 11 As shown,

[0075] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0076] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

[0077] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O 25 Eu2+ Dy 3+ A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0078] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0079] The transparent glaze layer (4) has a black glaze printed on a specific area on the upper surface, which is then sintered to form an arrow-shaped, text (safety exit) and letter (EXIT) black glaze marking layer (5) to form a light-shielding and color-developing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) is formed by printing the black glaze marking layer (5) once or in multiple printings. It can also be formed by printing two-color or multi-color glaze marking layers (such as arrows and text / letters with different colors).

[0080] The upper surface of the glaze marking layer (5) is also combined with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) covers the upper surface of the glaze marking layer (5). The anti-slip and light-transmitting structural layer (6-1) is a light-transmitting glaze sintered anti-slip layer with its bottom surface sintered with the top surface of the glaze marking layer (5) and its top surface having multiple upwardly protruding particles distributed in a sprinkle pattern; or it is a light-transmitting glaze sintered uneven anti-slip layer with its bottom surface sintered with the top surface of the glaze marking layer (5) and its top surface having multiple grid-like protrusions that are opposite to the sunken glaze mesh pattern; or it is a light-transmitting glaze sintered uneven anti-slip layer with its bottom surface sintered with the top surface of the glaze marking layer (5) and its top surface having a frosted surface formed. It can be printed and sintered in one or multiple times.

[0081] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright light (high illumination environment), visual identification is mainly achieved through the color contrast (black contrasting with light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark light (low illumination environment), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent contrasting with yellow-green afterglow luminescence). They have high recognition, good anti-slip performance and are not easy to accumulate dust, and have high practicality and economic value.

The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) is formed by printing the black glaze marking layer (5) once or in multiple printings. It can also be formed by printing two-color or multi-color glaze marking layers (such as arrows and text / letters with different colors).

[0089] The upper surface of the glaze marking layer (5) is also combined with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) covers and extends beyond the upper surface of the glaze marking layer (5) to the upper surface of the transparent glaze layer (4) surrounding the glaze marking layer (5), forming enlarged arrows and rectangular text and letter frames. The anti-slip and light-transmitting structural layer (6-1) is formed by printing and sintering the light-transmitting glaze in one or multiple times. The sintering softening point is higher than that of the transparent glaze layer (4) and the glaze marking layer (5). The bottom surface of the anti-slip and light-transmitting structural layer 1 (6-1) is sintered with the top surface of the transparent glaze layer (4), and the bottom surface of the anti-slip and light-transmitting structural layer 1 (6-1) is sintered with the top surface of the glaze marking layer (5). On the top surface of the anti-slip and light-transmitting structural layer 1 (6-1), due to the fact that the top of the light-transmitting glaze has not melted and leveled, a textured anti-slip layer with a frosted feel is formed by sintering granular light-transmitting glaze.

[0090] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright light (high illumination environment), visual identification is mainly achieved through the color contrast (black contrasting with light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark light (low illumination environment), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent contrasting with yellow-green afterglow luminescence). They have high recognition, good anti-slip performance and are not easy to accumulate dust, and have high practicality and economic value.

The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) is formed by printing black glaze marking layer (5) in one or multiple times. It can also be formed by printing two-color or multi-color glaze marking layer (such as arrows and text, letters, each selected with different colors).

[0098] The upper surface of the glaze marking layer (5) is also combined with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) covers the upper surface of the glaze marking layer (5). The anti-slip and light-transmitting structural layer (6-1) is a light-transmitting glaze sintered anti-slip layer with its bottom surface sintered with the top surface of the glaze marking layer (5) and its top surface having multiple upwardly protruding particles distributed in a dotted pattern. It can be printed and sintered in one or multiple times.

[0109] Example 5

[0110] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 10 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 15 As shown,

[0111] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0112] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

[0113] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O25 Eu 2+ Dy 3+ A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0114] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0115] The transparent glaze layer (4) has a black glaze printed on a specific area on the upper surface, which is then sintered to form an arrow-shaped, text (safety exit) and letter (EXIT) black glaze marking layer (5) to form a light-shielding and color-developing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing in one or multiple times to form a black glaze marking layer (5), or by printing in multiple times to form a two-color or multi-color glaze marking layer (such as arrows and text, letters, each selected in a different color).

[0116] The upper surface of the glaze marking layer (5) is bonded with an anti-slip and light-shielding structural layer two (6-2). The anti-slip and light-shielding structural layer two (6-2) exactly covers the upper surface of the glaze marking layer (5). The anti-slip and light-shielding structural layer two (6-2) is a black light-shielding glaze sintered anti-slip layer with its bottom surface sintered with the top surface of the glaze marking layer (5) and having multiple raised particles distributed in a dotted pattern on its top surface.

[0117] The transparent glaze layer (4) and the second anti-slip light-shielding structure layer (6-2) are respectively combined with a diagonal array of anti-slip light-transmitting structure layer one (6-1). The first anti-slip light-transmitting structure layer one (6-1) is a light-transmitting glaze sintered anti-slip layer with its bottom surface sintered with the top surface of the transparent glaze layer (4) and the top surface of the printed glaze marking layer (5).

[0119] Example 6

[0120] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 4 , 7 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 16 As shown,

[0121] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0122] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

[0123] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O 25 Eu 2+ Dy 3+ A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0124] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0125] The transparent glaze layer (4) has a black glaze printed on a specific area on the upper surface, which is then sintered to form a black glaze marking layer (5) with a hollow arrow shape and text (patrol route), forming a light-shielding and color-revealing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing in one or multiple times to form a black glaze marking layer (5), or by printing in multiple times to form a two-color or multi-color glaze marking layer (e.g., the hollow arrow and text are selected in different colors, such as the hollow arrow being black and the text being green).

[0126] The upper surface of the hollowed-out arrow glaze marking layer (5) is bonded with an anti-slip and light-shielding structural layer two (6-2). The anti-slip and light-shielding structural layer two (6-2) exactly covers the upper surface of the hollowed-out arrow glaze marking layer (5). The anti-slip and light-shielding structural layer two (6-2) is a black light-shielding glaze sintered anti-slip layer with multiple raised particles distributed in a dotted pattern on its top surface, which can be printed and sintered in one or multiple times.

[0127] The transparent glaze layer (4) in the hollowed-out area of ​​the hollowed-out arrow glaze marking layer (5), the transparent glaze layer (4) in the text glaze marking layer (5) and the transparent glaze layer (4) in the surrounding rectangular frame are respectively combined with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) is formed by printing and sintering the light-transmitting glaze in one or several times. The sintering softening point of the anti-slip and light-transmitting structural layer (6-1) is higher than that of the transparent glaze. The sintering softening point of the glaze layer (4) and the glaze marking layer (5) is such that the bottom surface of the anti-slip and light-transmitting structural layer one (6-1) is sintered with the top surface of the transparent glaze layer (4), and the bottom surface of the anti-slip and light-transmitting structural layer one (6-1) is sintered with the top surface of the glaze marking layer (5). On the top surface of the anti-slip and light-transmitting structural layer one (6-1), due to the fact that the top of the light-transmitting glaze has not melted and leveled, a textured anti-slip layer with a frosted feel is formed by sintering granular light-transmitting glaze.

[0128] Alternatively, the transparent glaze layer (4) in the hollow area of ​​the hollowed-out arrow glaze marking layer (5) may also be combined with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) is a granular light-transmitting glaze sintered uneven anti-slip layer formed by sintering dry particles of light-transmitting glaze mixed with inorganic reflective particles with reflective flashing function. Thus, the hollowed-out area of ​​the hollowed-out arrow glaze marking layer (5) has dual functions of luminescence and reflective flashing, which can improve the recognizability of the marking tiles.

[0129] Furthermore, the transparent glaze layer (4) in the hollowed-out area of ​​the hollowed-out arrow glaze marking layer (5) is also bonded with an anti-slip and light-transmitting structural layer (6-1), wherein the anti-slip and light-transmitting structural layer (6-1) is a light-transmitting glaze material with dry particles doped with SrAl2O4:Eu 2+ Dy 3+ The granular sintered uneven anti-slip layer formed by sintering long-afterglow luminescent powder, and the long-afterglow luminescent layer (3) is Sr4Al 14 O 25 Eu 2+ Dy 3+ The long-afterglow luminescent powder and the translucent glaze are mixed and sintered in a certain mass ratio. Therefore, the hollow area inside the hollow arrow glaze marking layer (5) has a yellow-green long-afterglow luminescent function, while the long-afterglow luminescent layer (3) has a blue-green long-afterglow luminescent function. Thus, the marking tile has a long-afterglow dual-color luminescent function, which can improve the recognizability of the marking tile.

[0130] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright light (high illumination environment), visual identification is mainly achieved through the color contrast (black contrasting with light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark light (low illumination environment), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent contrasting with yellow-green afterglow luminescence). They have high recognition, good anti-slip performance and are not easy to accumulate dust, and have high practicality and economic value.

[0132] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 10 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 17 As shown,

[0133] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0134] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

[0135] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O 25 Eu 2+ Dy 3+ A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0136] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0137] The transparent glaze layer (4) has a black glaze printed on a specific area on the upper surface, which is then sintered to form a black glaze marking layer (5) with a hollow arrow shape and text (patrol route), forming a light-shielding and color-revealing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing in one or multiple times to form a black glaze marking layer (5), or by printing in multiple times to form a two-color or multi-color glaze marking layer (e.g., the hollow arrow and text are selected in different colors, such as the hollow arrow being black and the text being green).

[0138] The upper surface of the glaze marking layer (5) is bonded with an anti-slip and light-shielding structural layer two (6-2). The anti-slip and light-shielding structural layer two (6-2) exactly covers the upper surface of the glaze marking layer (5). The anti-slip and light-shielding structural layer two (6-2) is formed by printing and sintering black glaze in one or multiple times. The sintering softening point of the anti-slip and light-shielding structural layer two (6-2) is higher than that of the sintering softening point of the glaze marking layer (5). The bottom surface of the anti-slip and light-shielding structural layer two (6-2) is sintered with the top surface of the glaze marking layer (5). Due to the fact that the top of the black glaze has not melted and leveled, a textured anti-slip layer with a frosted texture is formed on the top surface of the anti-slip and light-shielding structural layer two (6-2).

[0139] The transparent glaze layer (4) and the second anti-slip light-shielding structure layer (6-2) are respectively combined with a horizontally textured anti-slip light-transmitting structure layer (6-1) in a local area above them. The first anti-slip light-transmitting structure layer (6-1) is formed by printing and sintering the light-transmitting glaze in one or several times. The sintering softening point of the first anti-slip light-transmitting structure layer (6-1) is higher than that of the transparent glaze layer (4) and the second anti-slip light-shielding structure layer (6-2). The bottom surface of the first anti-slip light-transmitting structure layer (6-1) is sintered with the top surface of the transparent glaze layer (4) and with the bottom surface of the first anti-slip light-transmitting structure layer (6-1) and the top surface of the second anti-slip light-shielding structure layer (6-2). On the top surface of the first anti-slip light-transmitting structure layer (6-1), due to the fact that the top of the light-transmitting glaze has not melted and leveled, a granular light-transmitting glaze with a frosted feel is formed, creating an uneven anti-slip layer.

[0140] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright light (high illumination environment), visual identification is mainly achieved through the color contrast (black contrasting with light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P).

[0141] Example 8

[0142] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 4 , 9 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 18 As shown,

[0143] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0144] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

The body color is light yellow and the luminescence is yellow-green.

[0146] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0147] The transparent glaze layer (4) has a black glaze printed on a specific area on the upper surface, which is then sintered to form a black glaze marking layer (5) with a hollow arrow shape and text (patrol route), forming a light-shielding and color-revealing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing in one or multiple times to form a black glaze marking layer (5), or by printing in multiple times to form a two-color or multi-color glaze marking layer (e.g., the hollow arrow and text are selected in different colors, such as the hollow arrow being black and the text being green).

[0148] The upper surface of the hollowed-out arrow glaze marking layer (5) is bonded with an anti-slip and light-shielding structural layer two (6-2). The anti-slip and light-shielding structural layer two (6-2) exactly covers the upper surface of the hollowed-out arrow glaze marking layer (5). The anti-slip and light-shielding structural layer two (6-2) is formed by printing and sintering black glaze in one or multiple times. The sintering softening point of the anti-slip and light-shielding structural layer two (6-2) is higher than that of the sintering softening point of the glaze marking layer (5). The bottom surface of the anti-slip and light-shielding structural layer two (6-2) is sintered with the top surface of the glaze marking layer (5). On the top surface of the anti-slip and light-shielding structural layer two (6-2), due to the fact that the top of the black glaze has not melted and leveled, a granular black light-shielding glaze sintered uneven anti-slip layer with the required surface roughness is formed.

[0149] The upper surface of the printing mark layer (5) other than the transparent glaze layer (4) is also combined with a horizontally textured anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) is formed by sintering its bottom surface with the top surface of the transparent glaze layer (4) and the top surface of the printing mark layer (5). Its top surface has a light-transmitting glaze sintered uneven anti-slip layer with multiple grid-shaped protrusions that are opposite to the sunken printing mark pattern. It can be printed and sintered in one or multiple times.

[0150] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright light (high illumination environment), visual identification is mainly achieved through the color contrast (black contrasting with light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark light (low illumination environment), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent contrasting with yellow-green afterglow luminescence). They have high recognition, good anti-slip performance and are not easy to accumulate dust, and have high practicality and economic value.

[0151] Example 9

[0152] A long-afterglow luminescent anti-slip marking ceramic tile, from bottom to top, includes a base layer (1), a white reflective glaze layer (2), a long-afterglow luminescent layer (3), and a transparent glaze layer (4), as shown in the schematic diagram of its partial cross-sectional structure. Figure 3 As shown, its front structure and its hierarchical structure labeled from top to bottom are illustrated in the following diagram. Figure 19 As shown,

[0153] The base layer (1) is a bottom layer with a thickness of about 15 mm.

[0154] The white reflective glaze layer (2) is a white glaze reflective layer with a thickness of about 0.3 mm.

[0155] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O 25 Eu 2+ Dy 3+ A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0156] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0157] The transparent glaze layer (4) has a red glaze marking layer (5) on a specific area on its upper surface, which is printed with red glaze and sintered to form a footprint pattern and text (inspection point) to form a light-shielding color-displaying graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing red glaze marking layer (5) once or in multiple times.

[0158] The upper surface of the glaze marking layer (5) is also combined with an anti-slip and light-shielding structural layer two (6-2). The anti-slip and light-shielding structural layer two (6-2) exactly covers the upper surface of the glaze marking layer (5). The anti-slip and light-shielding structural layer two (6-2) is a red light-shielding glaze sintered anti-slip layer with multiple raised particles of red light-shielding glaze sintered on its bottom surface and the top surface of the glaze marking layer (5) being sintered together. It can be printed and sintered in one or multiple times.

[0159] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright fields (high illuminance environments), visual identification is mainly achieved through the color contrast (red versus light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark fields (low illuminance environments), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent versus yellow-green afterglow luminescence). They have high recognizability, good anti-slip performance, and are not prone to dust accumulation, making them highly practical and economical.

[0164] The long afterglow luminescent layer (3) is SrAl2O4:Eu 2+ Dy 3+ Long-afterglow luminescent powder and / or Sr4Al 14 O 25 Eu 2+ Dy 3+A sintered layer with a thickness of about 3mm is formed by mixing and sintering long-afterglow luminescent powder and translucent glaze in a certain mass ratio. The body color is light yellow and the luminescence is yellow-green.

[0165] The transparent glaze layer (4) is a sintered layer with a thickness of about 0.8 mm, formed by sintering a translucent glaze.

[0166] The transparent glaze layer (4) has a red glaze marking layer (5) with a footprint pattern and text (inspection point) printed on a negative plate in a specific area on the upper surface. This red glaze marking layer (5) forms a light-shielding color-developing graphic area (S). The remaining areas on the transparent glaze layer (4) without the glaze marking layer (5) form a light-transmitting and light-emitting area (P). The glaze marking layer (5) can be formed by printing the red glaze marking layer (5) once or in multiple times.

[0167] The upper surface of the glaze marking layer (5) is also bonded with an anti-slip and light-transmitting structural layer (6-1). The anti-slip and light-transmitting structural layer (6-1) exactly covers the upper surface of the glaze marking layer (5). The anti-slip and light-transmitting structural layer (6-1) is formed by printing and sintering the light-transmitting glaze in one or several stages. The sintering softening point of the anti-slip and light-transmitting structural layer (6-1) is higher than that of the transparent glaze layer (4) and the glaze marking layer (5).

On the top surface of the anti-slip and light-transmitting structural layer one (6-1), due to the unmelted and unleveled top of the light-transmitting glaze, a textured anti-slip layer with a frosted feel is formed. Alternatively, the anti-slip and light-transmitting structural layer one (6-1) can be sintered as a whole with the bottom surface of the glaze marking layer (5), and its top surface is sintered to form a frosted surface light-transmitting glaze sintered anti-slip layer.

[0168] The long-afterglow luminescent anti-slip marking tiles of this embodiment are suitable for emergency response, fire protection, greenways, parks, water conservancy, power, underground construction sites, beautification and other fields or places. The patterns are clear and durable. In bright fields (high illuminance environments), visual identification is mainly achieved through the color contrast (red versus light yellow) between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P). In dark fields (low illuminance environments), visual identification is mainly achieved through the contrast between the light-shielding color-developing graphic area (S) and the light-transmitting luminescent area (P) (non-luminescent versus yellow-green afterglow luminescence). They have high recognizability, good anti-slip performance, and are not prone to dust accumulation, making them highly practical and economical.
