Description

Technical Field

[0001] This invention relates to a gap-filling structure for laminated glass components, laminated glass, and its preparation method, belonging to the field of glass preparation technology. Background Technology

[0002] The application of laminated glass technology is becoming more and more widespread. Existing heat insulation, heating, display, and dimming glass all use laminated glass technology. With the application of large-size glass such as skylights, higher requirements are being placed on existing laminated glass.

[0003] To address issues such as wrinkles in internal functional components of laminated glass and difficulties in the lamination process, CN115362139B provides a solution to reduce wrinkles in laminated glass. Specifically, the internal functional components are divided into two pieces within a single piece of glass, with a gap of more than 15mm between the two pieces. The gap between the two functional components is then filled with a resin film (mainly PVB).

[0004] However, when the distance between the two functional components is relatively small, the width of the resin film used for filling is relatively small, making it difficult to position during filling and making the process more difficult. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this invention is to provide a gap-filling structure for laminated glass components, which enables accurate positioning during the gap-filling process.

[0008] The sealing film includes an adhesive portion and an extension portion.

[0009] In use: the first upper sealing film and the first lower sealing film, the second upper sealing film and the second lower sealing film respectively cover the opposite edges of the adjacent first component and the second component. The extension of the first upper sealing film and the extension of the first lower sealing film extend from the side of the first component to the gap between the side of the first component and the side of the second component. The extension of the second upper sealing film and the extension of the second lower sealing film extend from the side of the second component to the gap between the side of the first component and the side of the second component.

[0010] The extension of the first upper sealing film is attached to the extension of the first lower sealing film, and the extension of the second upper sealing film is attached to the extension of the second lower sealing film.

[0011] The laminated glass gap filling structure provided by this invention includes four sets of sealing films. These sealing films are used to seal the edges of two opposing components. After sealing, the extension portion of the sealing film extends into the gap between the two components. During edge filling positioning, due to the presence of this extension portion, whether the edge filling operation is performed manually or by machine such as an adhesive dispensing device, the positioning can be accurate and fast, thus making the operation more convenient and solving the problems of positioning difficulties and process difficulties in edge filling operations in the prior art. Moreover, due to the supporting role of the extension portion, it is also convenient to fill the edge filling adhesive, which is conducive to forming a uniform filling adhesive sheet.

[0012] In the above-described gap-filling structure for laminated glass components, preferably, the first and second components are flat or membrane-like components arranged side-by-side in the laminated glass. The gap-filling structure for laminated glass components provided by this invention is applicable to gap-filling operations between any components disposed within laminated glass.

[0013] In the above-mentioned gap-filling structure for laminated glass components, preferably, the bonding portion of the first upper sealing film is bonded to the upper surface of the first component, and the bonding portion of the first lower sealing film is bonded to the lower surface of the first component.

[0015] By attaching the bonding parts separately to the lower surface of the component, the edge sealing film can be fixed, achieving a good edge sealing effect.

[0016] In the above-mentioned gap-filling structure for laminated glass components, preferably, the first upper sealing film and the second upper sealing film further include a bending portion, the bending portion connecting the bonding portion and the extension portion; and / or, the first lower sealing film and the second lower sealing film further include a bending portion, the bending portion connecting the bonding portion and the extension portion.

By attaching the bent portions to the sides of the components respectively, the sealing films can be fixed, achieving a good sealing effect.

[0018] In the gap-filling structure of the laminated glass components of the present invention, the sealing film mainly consists of an adhesive portion and an extension portion, and the bending portion is an optional structure. Specifically, the first upper sealing film, the first lower sealing film, the second upper sealing film, and the second lower sealing film can have the following structures. It should be noted that the following structures are exemplary structures, and the actual structures that can be used are not limited to these:

[0019] The first structure: the first upper sealing film, the first lower sealing film, the second upper sealing film, and the second lower sealing film are each composed of an adhesive portion and an extension portion; this structure is preferably suitable for cases where the edge of the component is a beveled structure or a curved structure; in this structure, the adhesive portion of each sealing film can be adhered to the beveled structure surface or the curved structure surface of the component, and can extend towards the middle part of the component, that is, a part of the adhesive portion can be adhered to the part of the surface of the component within the beveled structure or the curved structure;

This structure is preferably suitable for situations where the surface and side of the component are perpendicular or at a certain angle, and the side can be a plane, an inclined plane, or an arc surface. In this structure, the adhesive part of each sealing film is attached to the surface of the component, and the bending part of the first and second lower sealing films is attached to the entire side (or end face) of the first component and the entire side (or end face) of the second component, respectively.

In this structure, the adhesive portion of each edge sealing film is attached to the surface of the component; the bending portion of the first and second upper edge sealing films is attached to a portion of the side (or end face) of the first component and a portion of the side (or end face) of the second component, respectively; the bending portion of the first and second lower edge sealing films is attached to a portion of the side (or end face) of the first component and a portion of the side (or end face) of the second component, respectively.

[0023] In the above-mentioned gap-filling structure for laminated glass components, preferably, the sum of the lengths of the extensions of the first upper sealing film and the second upper sealing film is less than or equal to the width of the gap.

[0024] When the sum of the lengths of the extensions of the first and second upper edge sealing films is less than the width of the gap, there can be a certain gap (or notch) between the first and second upper edge sealing films. When filling with adhesive, the adhesive will enter this gap, thereby increasing the contact area with the first and second upper edge sealing films and thus improving the bonding force.

In this case, when filling adhesive on one side, the adhesive will enter the other side through this gap, thereby partially or completely filling the gap space on the other side, thus fixing the extensions of each sealing film together. However, in this case, a gasket or other device needs to be set on the other side to seal the adhesive application area on the other side, preventing adhesive from leaking onto the adhesive application platform and causing problems such as adhesive leakage or insufficient adhesive.
