Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, specifically a high-temperature resistant and UV-resistant laminated glass. Background Technology

[0002] Laminated glass, a type of safety glass, is made of two or more layers of glass substrates bonded together with an interlayer. There are two main methods: hot pressing (dry method) and grouting (wet method). In the dry method, an interlayer film is sandwiched between glass sheets and bonded through a hot pressing process. In the wet method, liquid resin is injected between two glass sheets and cured to form a laminate. Laminated glass has advantages such as impact resistance, drop protection, sound insulation, and heat insulation, and has been widely used in building curtain walls, high-rise building windows, car sunroofs, photovoltaic module covers, outdoor advertising light boxes, and other applications.

[0003] However, existing laminated glass generally has low strength and is prone to breakage under external impact. Furthermore, its UV protection is generally poor, allowing UV rays to easily penetrate and irradiate the human body, potentially causing radiation damage. To overcome these shortcomings, existing technology (Chinese patent application number 202320804102.3, application date 2023-04-12) provides a high-strength UV-resistant laminated glass. This glass utilizes a combination of tempered glass, laminated glass, and wired glass to form an outer pressure-resistant glass layer, increasing its strength and reducing breakage under external impact. It also utilizes a combination of heat-reflective glass, UV absorber, and UV glass to further enhance UV protection and reduce UV penetration. Finally, it utilizes a combination of a first borosilicate tempered layer, a soda-lime high-temperature glass layer, and a second borosilicate tempered layer to form a high-temperature resistant glass layer, improving its high-temperature resistance and reducing the risk of breakage due to high temperatures.

[0004] However, the connection method of the composite layers in the above-mentioned laminated glass structure is relatively simple, resulting in loose connections between the composite layers. This may lead to interlayer delamination, bubbles, or even separation of the glass substrate, which seriously affects the safety of use. In order to address the above problems, it is urgent to innovate the design based on the existing equipment. Therefore, we have proposed a high-temperature resistant and UV-resistant laminated glass that can effectively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant and UV-resistant laminated glass to solve the problem that the connection method of the composite layers in the above-mentioned laminated glass structure is relatively simple, resulting in loose connections between the composite layers, which may lead to interlayer delamination, bubbles, or even separation of the glass substrate, seriously affecting the safety of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature resistant and UV-resistant laminated glass, comprising a first glass substrate and a second glass substrate, wherein the first glass substrate and the second glass substrate are overlapped and pressed together, and an injection cavity for filling adhesive is provided between them; an injection port for injecting adhesive is also provided on one side of the first glass substrate and the second glass substrate.

[0007] The first glass substrate and the second glass substrate each include a first substrate and a second substrate, and the inner surfaces of the first substrate and the second substrate are arranged opposite to each other. Both can be made of high borosilicate glass. The inner surface of the first substrate is formed with positioning posts distributed in a matrix, and the inner surface of the second substrate is formed with positioning frames that are adapted to the positioning posts. The positioning posts are correspondingly snapped into the inner side of the positioning frames.

[0008] The inner surfaces of the first substrate and the second substrate are also formed with matching heat-conducting components for rapid heat dissipation.

[0009] The outer sides of the first glass substrate and the second glass substrate are also snapped together by a fixing frame around the perimeter, and the contact surfaces between the fixing frame and the first glass substrate and the second glass substrate are filled with adhesive.

[0010] Preferably, the edge of the injection cavity has an outwardly expanding trapezoidal structure. This structure not only increases the contact area between the adhesive and the two substrates, thereby improving the bonding strength, but its inclined slope can also increase the flow rate of the adhesive as it is injected into and fills the injection cavity, thereby improving the processing efficiency of laminated glass.

[0011] Preferably, the positioning frame is provided with multiple breaks. This structure allows adhesive to fill the contact surface between the positioning frame and the positioning post through the breaks, thereby effectively improving the stability of the connection between the two. In addition, the inner edge of the positioning frame and the outer edge of the positioning post are both formed into rounded corner structures.

[0012] Preferably, the first glass substrate further includes a first transition layer and an anti-ultraviolet layer sequentially covering the outer surface of the first substrate. The anti-ultraviolet layer may be made of nano-oxide coating, and the first transition layer may be made of borosilicate glass substrate that has undergone corresponding modification treatment. In addition, the outer surface of the anti-ultraviolet layer may also be provided with an anti-glare coating, which may be made of polyurethane resin.

[0013] Preferably, the second glass substrate further includes a second transition layer and a high-temperature resistant layer sequentially covering the outer surface of the second substrate. The high-temperature resistant layer may be a silica coating modified with a silane coupling agent, and the second transition layer may be a high borosilicate glass substrate that has undergone corresponding modification treatment.

[0014] Preferably, the heat-conducting element has a structure in which multiple vertical lines are intersected, and there is a gap between the heat-conducting elements on the first substrate and the second substrate.

[0015] Preferably, the two sides of the fixing frame are formed into a stepped chamfered structure, and the chamfers on both sides are reversed, and the chamfers between adjacent fixing frames are filled with adhesive.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This kind of high temperature and UV resistant laminated glass, through the composition of the glass substrate and the corresponding snap-fit ​​of the positioning posts and positioning frames, can effectively enhance the tightness and stability of the glass substrate connection, thereby effectively avoiding the occurrence of interlayer delamination, bubbles, or even separation of the glass substrate, so as to ensure the safety of the laminated glass; and through the heat-conducting components on the inner side of the two substrates, heat can be quickly dispersed to prevent the glass from cracking or even shattering due to uneven heating. The specific contents are as follows: (1) Through the corresponding snap-fit ​​of multiple sets of positioning posts and positioning frames, and the bonding of the positioning posts and positioning frames by the adhesive liquid in the glue injection cavity, the tightness and stability of the connection of the two glass substrates can be effectively enhanced, thereby effectively avoiding the occurrence of interlayer delamination, bubbles, or even separation of the glass substrate, so as to ensure the safety of the laminated glass.

[0017] (2) By providing heat-conducting components on the inner side of the first substrate and the second substrate, heat can be evenly conducted to all parts of the first glass substrate and the second glass substrate when the laminated glass is heated at high temperature, so as to quickly disperse the heat and prevent the glass from cracking or even shattering due to uneven heating.

[0018] (3) The first glass substrate is formed by the first substrate, the first transition layer and the anti-ultraviolet layer, which can effectively resist ultraviolet rays. The second glass substrate is formed by the second substrate, the second transition layer and the high temperature resistant layer, which can reduce the aging of the glass interface at high temperature and improve the scratch resistance of the glass.

[0019] (4) Through the stepped chamfered structure on both sides of the fixed frame, the vertical joint of the adjacent fixed frames can be stably fitted by the chamfered structure and the adhesive bonding effect, thereby ensuring the stable connection of the four fixed frames to the two glass substrates.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-5 This utility model provides the following technical solution: a high-temperature resistant and UV-resistant laminated glass, comprising a first glass substrate 1 and a second glass substrate 2, which are overlapped and pressed together, and an adhesive injection cavity 3 for filling adhesive is provided between them. An adhesive injection port 4 for injecting adhesive is also provided on one side of the first glass substrate 1 and the second glass substrate 2. The adhesive can be a silane coupling agent modified epoxy resin, which has strong adhesion and excellent water resistance and high-temperature resistance, ensuring the stability of the bonding between the first glass substrate 1 and the second glass substrate 2. The edge of the adhesive injection cavity 3 has an outwardly expanding trapezoidal structure. This structure can not only increase the contact area between the adhesive and the first substrate 101 and the second substrate 201, thereby improving the bonding strength, but its inclined slope can also increase the flow rate of the adhesive injected into the filling cavity 3, thereby improving the processing efficiency of the laminated glass.

[0029] The first glass substrate 1 and the second glass substrate 2 each include a first substrate 101 and a second substrate 201, with the inner surfaces of the first substrate 101 and the second substrate 201 facing each other. Both are made of high borosilicate glass with a thickness of 3.0mm to 8.0mm. The inner surface of the first substrate 101 is formed with positioning posts 104 arranged in a matrix, and the inner surface of the second substrate 201 is formed with positioning frames 204 that are adapted to the positioning posts 104. The positioning posts 104 are correspondingly engaged with the inner side of the positioning frames 204. Through the corresponding engagement of multiple sets of positioning posts 104 and positioning frames 204, and the adhesion of the positioning posts 104 and positioning frames 204 by the adhesive in the injection cavity 3, the tightness and stability of the connection between the first glass substrate 1 and the second glass substrate 2 can be effectively enhanced. This can effectively prevent interlayer delamination, bubbles, or even separation of the glass substrates, thus ensuring the safety of the laminated glass.

[0030] Furthermore, the positioning frame 204 is provided with multiple breaks. This structure allows the adhesive to fill the contact surface between the positioning frame 204 and the positioning post 104 through the breaks during glue injection, thereby effectively improving the stability of the connection between the two. In addition, the inner edge of the positioning frame 204 and the outer edge of the positioning post 104 are both formed into rounded corner structures, so that the two can be accurately connected along the arc surface.

[0031] In addition, the first glass substrate 1 also includes a first transition layer 102 and an anti-ultraviolet layer 103 sequentially covering the outer surface of the first substrate 101. The overall thickness of the first transition layer 102 and the anti-ultraviolet layer 103 is 1.0 mm to 1.5 mm. The anti-ultraviolet layer 103 can be made of nano-oxide coating, such as nano-TiO2, ZnO, or SiO2 coating. This material can effectively resist ultraviolet rays. The first transition layer 102 can be made of borosilicate glass substrate that has undergone corresponding modification treatment to ensure the adhesion strength between the anti-ultraviolet layer 103 and the first substrate 101. In addition, an anti-glare coating can be provided on the outer surface of the anti-ultraviolet layer 103. The anti-glare coating can be made of polyurethane resin, which can not only prevent glare but also improve the impact resistance of the first glass substrate 1.

[0032] Meanwhile, the second glass substrate 2 also includes a second transition layer 202 and a high-temperature resistant layer 203 sequentially covering the outer surface of the second substrate 201. The overall thickness of the second transition layer 202 and the high-temperature resistant layer 203 is 0.8mm to 1.2mm. The high-temperature resistant layer 203 can be a silica coating modified with a silane coupling agent to form a dense heat-resistant film on the surface of the second glass substrate 2, reducing glass interface aging at high temperatures and improving the scratch resistance of the glass. The second transition layer 202 can be a high borosilicate glass substrate that has undergone corresponding modification treatment to ensure the coating strength between the high-temperature resistant layer 203 and the second substrate 201.

[0033] Example 2: Based on Example 1, please refer to... Figures 1-3 , Figures 5-6 The inner surfaces of the first substrate 101 and the second substrate 201 are also formed with matching heat-conducting elements 5, which are used to evenly conduct heat to the first glass substrate 1 and the second glass substrate 2 when the laminated glass is heated at high temperature, so as to quickly disperse the heat and prevent the glass from cracking or even shattering due to uneven heating. Furthermore, the heat-conducting elements 5 have a structure in which multiple vertical lines are intersected, and there is a gap between the heat-conducting elements 5 on the first substrate 101 and the second substrate 201 so that the adhesive can flow smoothly and fill the glue cavity 3 through the gap.

[0034] In addition, the outer sides of the first glass substrate 1 and the second glass substrate 2 are also fixed by a fixing frame 6 around the perimeter. The contact surfaces between the fixing frame 6 and the first glass substrate 1 and the second glass substrate 2 are filled with adhesive. The two sides of the fixing frame 6 are formed into a stepped chamfered corner structure 7, and the chamfered corners 7 on both sides are reversed. Adhesive is also filled between the chamfered corners 7 of adjacent fixing frames 6. This structure allows the four fixing frames 6 to be fixed to the outer sides of the first glass substrate 1 and the second glass substrate 2. The vertical contact points of adjacent fixing frames 6 can achieve a stable fitting structure through the chamfered corner structure 7 and the adhesive bonding effect, thereby ensuring the stability of the combination of the four fixing frames 6 in the fixing of the first glass substrate 1 and the second glass substrate 2.
