Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, specifically to a type of laminated glass for building applications. Background Technology

[0002] Laminated glass, also known as laminated glass or safety laminated glass, is a composite safety glass that is usually made of two or more layers of glass bonded together by one or more layers of organic polymer interlayer. Depending on the interlayer material and process, it is mainly divided into dry laminated glass and wet (filling) laminated glass. Wet laminated glass is mainly used for interior decorative glass and simple safety glass where long-term weather resistance requirements are not high.

[0003] Wet-laid glass can usually be fabricated on-site. During processing, an edge banding is first placed between the first and second layers of glass. Then, the edges of the two layers of glass are fixed with clips, leaving one side for injecting the adhesive. The glass is then laid flat and pressed or a vacuum pump is used to spread the adhesive evenly. Finally, it is cured. The sealing effect between the edge banding and the glass is particularly important in wet-laid glass. However, the existing sealing between the edge banding and the glass is mainly a single seal, and the gap between the edge banding and the glass is linear, resulting in limited sealing effect. During the injection of adhesive and long-term use, leakage and external corrosion are prone to occur, affecting the performance of the laminated glass. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a laminated glass for building applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A laminated glass for building includes an outer glass layer and an inner glass layer, which are connected by an adhesive layer. A sealing component is provided on the side of the outer glass layer and the inner glass layer that are close to each other, and the sealing component is located at the edge of the adhesive layer for sealing the adhesive layer.

[0007] The sealing assembly includes two sets of first sealing grooves, which are respectively opened on the side of the outer glass layer and the inner glass layer that are close to each other, and a first edge strip is provided between the two first sealing grooves.

[0008] The two first sealing grooves are connected to a second sealing groove on the side away from the colloid layer. The two second sealing grooves are respectively opened at the edges of the outer glass layer and the inner glass layer, and a second edge strip is connected to the inner side of the second sealing groove.

[0009] Furthermore, the first sealing groove is arc-shaped, and the middle parts of the arcs of the first sealing groove on the outer glass layer and the first sealing groove on the inner glass layer are far apart from each other, and the first edge strip is adapted to the first sealing groove.

[0010] Furthermore, the top and bottom of the second edging strip are both provided with protrusions;

[0011] The second sealing groove has a slot on the side away from the first sealing groove. After the second edge strip is installed, the inner wall of the slot engages with the protrusion.

[0012] Furthermore, both the second and first edge strips are made of silicone.

[0013] Furthermore, a first protective layer is connected to the side of the outer glass layer away from the colloidal layer. The first protective layer is a SiO2-based nanocomposite coating, which serves to prevent scratches.

[0014] Furthermore, a second protective layer is connected to the side of the inner glass layer away from the colloidal layer, and the second protective layer is an anti-fouling nano-coating.

[0015] Compared with existing technologies, this laminated glass for building applications has the following advantages:

[0016] This invention solves the problem that existing laminated glass uses a single seal, and the gap between the edge and the glass is linear, resulting in a limited sealing effect that affects the performance of laminated glass. This is achieved by opening a first sealing groove and a second sealing groove on the outer glass layer and the inner glass layer respectively, and distributing a first edge strip and a second edge strip within the first sealing groove and the second sealing groove respectively.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a laminated glass for building, including an outer glass layer 2 and an inner glass layer 6, which are connected by an adhesive layer 3. A sealing component is provided on the side of the outer glass layer 2 and the inner glass layer 6 that are close to each other, and the sealing component is located at the edge of the adhesive layer 3 for sealing the adhesive layer 3. The sealing component includes two sets of first sealing grooves, which are respectively opened on the side of the outer glass layer 2 and the inner glass layer 6 that are close to each other, and a first edge strip 4 is provided between the two first sealing grooves. A second sealing groove is connected to the side of the two first sealing grooves away from the adhesive layer 3. The two second sealing grooves are respectively opened at the edges of the outer glass layer 2 and the inner glass layer 6, and a second edge strip 5 is connected to the inner side of the second sealing groove.

[0024] In use, corresponding first and second sealing grooves are respectively opened on the sides of the outer glass layer 2 and the inner glass layer 6 that are close to each other. First, the first edge strip 4 is laid around the outer glass layer 2 and the inner glass layer 6, so that the first edge strip 4 is embedded in the first sealing groove. The first edge strip 4 is positioned with its ends connected near the top corner of one side of the glass, and this side is left unlaid, so that the other three sides of the glass are sealed to facilitate glue injection. Then, the second edge strip 5 is laid, and the position where the second edge strip 5 contacts the first edge strip 4 is glued. The first and second ends of the second edge strip 5 are positioned near the top corner of the glass, on the same side as the first edge strip 4, covering three sides, leaving one side unlaid for glue injection. Then, the three sides are clamped and fixed along the edge of the glass, and glue is injected between the outer glass layer 2 and the inner glass layer 6. After the glue injection is completed, the first edge strip 4 on the glued side is... Insert the first sealing strip 4 into the first sealing groove, sealing the glue-filled side and leaving only the joints at the beginning and end for venting. Then, attach the second edge strip 5 to the edge of the glass, clamp the edge of the glass with the second edge strip 5 inside the clamp, and then flatten and press the glass while using a vacuum pump to evacuate air, allowing the colloid layer 3 to circulate inside and vent through the joints at the beginning and end of the first edge strip 4. By tilting the glass appropriately, the colloid layer 3 is forced to flow preferentially towards the part away from the vent, venting the gas away from the vent. Then, flatten the glass and gradually vent the gas near the vent, so that the colloid layer 3 is evenly distributed. After the colloid layer 3 is evenly distributed, connect the first edge strip 4 end to end and insert the second edge strip 5 into the second sealing groove. Finally, let it cure. During installation, the joints at the beginning and end of the first edge strip 4 and the second edge strip 5 are staggered to facilitate wrapping and sealing the edge of the first edge strip 4, improving the sealing effect.

[0025] The first sealing groove is arc-shaped, and the middle parts of the arcs of the first sealing groove on the outer glass layer 2 and the first sealing groove on the inner glass layer 6 are far apart from each other. The first edge strip 4 is adapted to the first sealing groove. In use, the first edge strip 4 is made of silicone material. The top and bottom of the first edge strip 4 are arc-shaped structures that protrude outwards and contact the inner wall of the first sealing groove to form a bent gap and improve the sealing effect on the colloid layer 3.

[0026] The second edge strip 5 has protrusions 8 at both its top and bottom; a slot is provided on the side of the second sealing groove away from the first sealing groove, and the inner wall of the slot engages with the protrusion 8 after the second edge strip 5 is installed; the material of the second edge strip 5 is silicone; one side of the inner wall of the second edge strip 5 is in contact with the side of the first edge strip 4 away from the adhesive layer 3, and the side of the second edge strip 5 away from the first edge strip 4 is coplanar with the outer side of the outer glass layer 2 and the outer side of the inner glass layer 6, so as to facilitate glass installation; the protrusion 8 is cylindrical in shape and its diameter is greater than the width at the connection point with the vertex of the second edge strip 5, so that the protrusion 8 can be inserted into the slot to achieve the function of engaging the second edge strip 5.

[0027] The outer glass layer 2 is connected to a first protective layer 1 on the side away from the colloidal layer 3. The first protective layer 1 is a SiO2-based nanocomposite coating, which serves to prevent scratches. In use, the SiO2-based nanocomposite coating can be formed using the sol-gel method. It is located on the side of the outer glass layer 2 away from the colloidal layer 3 and serves to prevent scratches. The inner glass layer 6 is connected to a second protective layer 7 on the side away from the colloidal layer 3. The second protective layer 7 is an anti-fouling nanocoating. Fluoropolymers (such as PTFE) or organosilicon solutions can be directly sprayed using a spraying / immersion method, and a film is formed after drying to improve the glass's resistance to scale and soap stains.
