Description

Technical Field

[0001] The utility model belongs to the field of ion intermediate membranes, in particular to an ion intermediate membrane. Background Art

[0002] Ionic interlayers, also commonly referred to as ionic interlayers or ionic interlayers, are thin film materials with unique properties. Their primary application in glass is in the manufacture of laminated glass, particularly to improve the safety, durability, and aesthetics of the glass.

[0003] In the manufacturing process of laminated glass, the most important thing is to discharge the gas generated when the glass and the ion-bonded interlayer are pressed together at high temperature. If the degassing performance of the ion-bonded interlayer is poor, it will cause bubbles in the finished laminated glass or defects such as partial incomplete lamination. Utility Model Content

[0004] The purpose of the present invention is to provide an ion intermediate membrane to overcome at least one of the above-mentioned defects in the prior art.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides an ion intermediate membrane, which comprises a substrate and bumps. The upper and lower surfaces of the substrate are both provided with a plurality of bumps, which are distributed in a matrix manner, and exhaust spaces are provided between adjacent bumps.

[0007] Preferably, the height of a bump is 1.2-5 times the shortest distance between two adjacent bumps.

[0008] Preferably, the height of the bump is 0.2-0.8 mm, and the maximum distance between two adjacent bumps is 0.5-1.2 mm.

[0009] Preferably, the longitudinal section of the projection is arc-shaped, triangular or trapezoidal.

[0010] Preferably, the projection and the base are integrally formed.

[0011] Preferably, the base and the bumps are both made of SGP.

[0012] Preferably, the thickness of the substrate is 0.6-1.8 mm.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting the bumps protruding from the surface of the substrate, when the laminated glass is pressed at high temperature, the gas between the glass plate and the ion interlayer will be discharged through the exhaust space, so that the finished laminated glass will not have bubbles or defects such as partial incomplete lamination.

[0015] 2. The bumps are used as the connecting layer between the glass plate, which is different from the traditional method of directly using the substrate as the connecting layer between the glass plate. This method does not damage the substrate, ensures the flatness between the ion interlayer and the glass plate, and improves the quality of the finished laminated glass.

[0016] 3. The use of several bumps distributed in a matrix can significantly increase the contact area between the ion-bonding interlayer and the glass plate; a larger contact area means more bonding points, and the bonding points are evenly distributed, thereby improving the bonding strength.

[0017] 4. Ensure efficient exhaust by limiting the height of the bumps and the distance between adjacent bumps.

[0018] 5. The integrally formed bumps and base avoid structural defects or instability at the joints caused by assembly.

[0019] 6. The longitudinal section of the bump is arc-shaped, triangular or trapezoidal, so that the exhaust space is from wide to narrow, which is more conducive to efficient exhaust. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0025] Any content not described in detail in this specification belongs to the prior art known to those skilled in the art. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating the description of the utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1 to 3 As shown, an ion intermediate membrane provided in this embodiment includes a substrate 1 and a bump 2. The upper and lower surfaces of the substrate 1 are provided with a plurality of bumps 2, and the bumps 2 are distributed in a matrix. There is an exhaust space 3 between adjacent bumps 2. The height of the bump 2 in this embodiment is 0.3 mm, the maximum distance between two adjacent bumps 2 is 1 mm, and the thickness of the substrate 1 is 1 mm. The height of the bump 2 is 1.8 times the shortest distance between two adjacent bumps 2. The longitudinal cross-section of the bump 2 is arc-shaped, so that the exhaust space 3 is from wide to narrow, which is more conducive to efficient exhaust. In other embodiments, it can also be triangular or trapezoidal. The material of the substrate 1 and the bump 2 is SGP. When the laminated glass is pressed at high temperature, the gas between the glass plate and the ion intermediate membrane will be discharged through the exhaust space 3, so that the finished laminated glass will not have bubbles or defects such as partial incomplete lamination. The surface of the substrate 1 is provided with bumps 2 arranged in a matrix. Because the bumps 2 protrude from the surface of the substrate 1, adjacent bumps 2 form exhaust spaces 3. During high-temperature pressing, the bumps 2 melt and collapse into the exhaust spaces 3, squeezing out the air within. By using the bumps 2 as a connecting layer between the glass sheets, unlike the traditional method of directly connecting the substrate 1 to the glass sheets, the substrate 1 is not damaged, the flatness between the ion-forming interlayer and the glass sheets is ensured, and the quality of the finished laminated glass is improved. The use of a plurality of bumps 2 arranged in a matrix can significantly increase the contact area between the ion-forming interlayer and the glass sheets. A larger contact area means more bonding points, and the bonding points are evenly distributed, thereby improving the bonding strength. Efficient exhaust is ensured by numerically limiting the height of the bumps 2 and the spacing between adjacent bumps 2.

[0027] The bump 2 and the base 1 are integrally formed, thereby avoiding structural defects or instability at the joints caused by assembly.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
