[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] This embodiment provides a roof tile, which is applied to the roof structure of a building. The upper surface of the roof tile is the light-facing side, has light-transmitting properties, and allows sunlight to enter the interior from the light-facing side. Figure 1-Figure 3 As shown, the roof tile includes a tile layer structure 100 and a frame strip 200. The frame strip 200 is installed on the side of the tile layer structure 100. On the one hand, it is used to protect the edge of the tile layer structure 100, and on the other hand, it solves the installation and waterproofing problems between the roof tiles.

[0032] Further, such as Figure 1 and Figure 2 As shown, the tile layer structure 100 includes a light-transmitting layer 110, a heat-absorbing adhesive layer 120 and a heat-insulating layer 130 which are stacked in sequence, wherein the light-transmitting layer 110 is configured as a transparent structure. The heat-absorbing adhesive layer 120 is configured as a non-transparent structure, and the heat-absorbing adhesive layer 120 adheres the heat-insulating layer 130 to the backlight side of the light-transmitting layer 110. The heat-absorbing adhesive layer 120 is used to absorb the thermal radiation incident through the light-transmitting layer 110; and the heat-insulating layer 130 is used to reflect the thermal radiation incident through the heat-absorbing adhesive layer 120.

[0033] Specifically, in addition to bonding and fixing the light-transmitting layer 110 and the heat-insulating layer 130, the heat-absorbing adhesive layer 120 also plays a role in absorbing heat. After the sunlight passes through the light-transmitting layer 110, a part of the heat radiation is absorbed by the heat-absorbing adhesive layer 120, and the other part of the heat radiation penetrates the heat-absorbing adhesive layer 120 and enters the heat-insulating layer 130. The heat-insulating layer 130 reflects the heat radiation toward the light side, and the heat radiation is reabsorbed by the heat-absorbing adhesive layer 120 or passes through the tile layer structure 100 again through the light-transmitting layer 110. The heat-insulating performance of the roof tiles is significantly improved by absorbing the heat radiation by the heat-absorbing adhesive layer 120 and reflecting the heat radiation by the heat-insulating layer 130. In addition, since the heat-absorbing adhesive layer 120 is set as a non-transparent structure, it also plays the role of a color-developing layer. According to the color requirements of the roof, the color of the heat-absorbing adhesive layer 120 can be adjusted accordingly, so that the appearance of the roof presents a uniform color or a specific graphic color to meet aesthetic requirements.

[0034] For example, the light-transmitting layer 110 can be made of transparent glass, PC (polycarbonate), GRP (glass fiber reinforced plastic) and other materials. In this embodiment, the light-transmitting layer 110 is made of tempered glass, which has excellent mechanical strength, thermal stability and safety. Furthermore, the light-transmitting layer 110 is made of tempered glass. When the light-transmitting layer 110 is broken, it will not fall apart. On the one hand, it ensures safety, and on the other hand, it makes the roof still have a certain degree of waterproofness, which buys some time for the replacement of damaged roof tiles.

[0035] Exemplarily, the thickness of the light-transmitting layer 110 is 3-6 mm.

[0036] Exemplarily, the heat-absorbing adhesive layer 120 covers the backlight side of the light-transmitting layer 110, and the area of ​​the heat-absorbing adhesive layer 120 is not less than the area of ​​the light-transmitting layer 110. On the one hand, the heat-absorbing adhesive layer 120 fully absorbs the sunlight penetrating from the light-transmitting layer 110, and on the other hand, the visible part of the tile layer structure 100 exposed to the light side is all the heat-absorbing adhesive layer 120, so as to maintain the uniformity of the appearance color of the light-facing side and improve the aesthetics.

[0037] Exemplarily, the heat absorbing adhesive layer 120 is black, red or cyan. In this embodiment, the heat absorbing adhesive layer 120 is made of a black adhesive film. On the one hand, it helps to improve the absorption rate of light, reduce the reflectivity, enhance the heat radiation absorption capacity, and prevent light from being projected into the interior of the building; on the other hand, it makes the tile layer structure 100 appear black in appearance, which meets the aesthetic requirements that most building roofs are dark in color. In some embodiments, the heat absorbing adhesive layer 120 can also be made of other dark-colored adhesive films such as red and cyan.

[0038] Exemplarily, the heat absorbing adhesive layer 120 is made of EVA film (ethylene-vinyl acetate copolymer film), POE film (polyolefin elastomer film), EPE film (co-extruded POE film) or PVB film (polyvinyl butyral film). In this embodiment, the heat absorbing adhesive layer 120 is made of black EVA film, which has high adhesion and good durability.

[0039] Exemplarily, the heat-absorbing adhesive layer 120 is bonded to the light-transmitting layer 110 and the heat-insulating layer 130 by a vacuum lamination process. The lamination pressure is small, thereby avoiding damage to the light-transmitting layer 110 and the heat-insulating layer 130 and ensuring that the air between the bonded layers is completely evacuated, effectively preventing the occurrence of defects such as bubbles and stratification, thereby improving the quality and reliability of the product.

[0040] Exemplarily, the heat insulating layer 130 covers the backlight side of the heat absorbing adhesive layer 120, and the area of ​​the heat insulating layer 130 is not less than the area of ​​the heat absorbing adhesive layer 120. On the one hand, the reflection area of ​​the heat radiation is increased, so that the heat insulating layer 130 can fully reflect the heat radiation incident from the heat absorbing adhesive layer 120, and on the other hand, the visible part of the backlight side of the tile layer structure 100 exposed is the heat insulating layer 130, so that the color uniformity of the backlight side is maintained and the aesthetics is improved.

[0041] Exemplarily, the heat insulating layer 130 is made of white PET film (polyethylene terephthalate film) or metal film, which can be aluminum foil or a film plated with metals such as nickel, silver, copper, etc., or a multi-layer metal film containing metals such as silver, titanium, aluminum, or metal oxides such as Ti2O3 and Al2O3 formed by magnetron sputtering technology, and the reflectivity of infrared rays is improved by a multi-layer reflective structure. The heat insulating layer 130 has the characteristics of heat radiation reflection while ensuring lightness and thinness, and can also present a white or metallic appearance on the backlight side.

[0042] Exemplarily, the light-facing side of the heat insulation layer 130 is configured as a mirror structure to reduce scattering and absorption of light during the reflection process, thereby increasing the reflectivity and further enhancing the heat insulation effect.

[0043] For example, Figure 1 and Figure 3 As shown, the frame strip 200 is provided with an installation slot 210, which is used to snap-fit ​​the edge of the tile layer structure 100, specifically snap-fit ​​the upper surface of the light-transmitting layer 110 and the lower surface of the heat-insulating layer 130. Specifically, the frame strip 200 is configured as a long strip structure, and the installation slot 210 is correspondingly configured as a long slot structure, both ends of which are provided with openings, so as to snap-fit ​​with the edge of the tile layer structure 100.

[0044] For example, Figure 1 and Figure 3As shown, the frame strip 200 further includes an overlap portion 220, which is arranged away from the mounting slot 210, and is provided with an overlap groove 230, the notch of which can be selectively arranged toward the backlight side and the light-facing side, and two adjacent frame strips 200 are overlapped by the overlap portions 220 with the notches facing each other. Specifically, as Figure 1 As shown, a frame strip 200 is respectively clamped on two opposite sides of each tile layer structure 100, and the notches on the two frame strips 200 face the backlight side, and the other faces the light side. During installation, the overlapping grooves 230 of adjacent frame strips 200 are buckled in a form where the notches face each other, so that the overlapping parts 220 are buckled with each other, which can not only realize the connection and installation between the two frame strips 200, but also the overlapping grooves 230 can play a water guiding function.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
