Description

Technical Field

[0001] The present invention relates to the technical field of colored crystal glass preparation, and in particular to an ultra-thin interlayer multi-textured colored crystal glass panel and a preparation method thereof. Background Art

[0002] With the advancement of technology, there are more and more types of glass, and its functions are becoming more and more extensive. It is widely used in buildings and household appliances. Therefore, not only the functional indicators of glass are required to meet the requirements, but also the appearance of glass is required to be beautiful and conform to the architectural aesthetics. The glass decorated on the existing colored crystal glass is mostly formed by direct printing of single-piece glass to form a decorative panel. Its disadvantages are poor appearance, no layered texture, and poor mechanical properties, which cannot meet the requirements.

[0003] Laminated glass is a composite glass product that is made by sandwiching one or more layers of organic polymer interlayer between two or more pieces of glass. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processing, the glass and the interlayer are permanently bonded together. Its application is already quite common.

[0004] An existing patent provides a high-strength colored laminated glass, including a first glass substrate, a first adhesive layer, a PMMA color film, a second adhesive layer, a polycarbonate plate, a third adhesive layer, and a second glass substrate stacked in sequence, wherein the first glass substrate and the PMMA color film are bonded by the first adhesive layer, the PMMA color film and the polycarbonate plate are bonded by the second adhesive layer, and the polycarbonate plate and the second glass substrate are bonded by the third adhesive layer. Although the glass uses a polycarbonate plate to improve its strength, its overall thickness is too thick and its weight is too heavy, so its application scenarios are limited; in addition, the glass only adjusts its color through color films, and as a decorative material or colored crystal glass, its color and pattern are relatively monotonous and cannot be selected, which not only lacks artistry, but also lacks decorative effects, and its use on colored crystal glass will also be limited. Summary of the invention

[0005] In view of the technical problems existing in the background technology, the present application provides an ultra-thin laminated multi-texture colored crystal glass panel and a preparation method thereof, aiming to solve the technical problems of existing colored crystal glass such as large overall thickness, heavy weight, poor color and poor performance.

[0006] In a first aspect, an embodiment of the present application provides a method for preparing an ultra-thin laminated multi-textured colored crystal glass panel, comprising the following steps:

[0007] S1, slicing, edge grinding and tempering the ultra-thin glass, performing pattern processing on the glass surface to obtain a coating with color and texture, and performing high temperature resistant film protection on the coating surface to obtain colored glass;

[0008] S2, cutting the middle decoration, the film and the back plate;

[0009] S3, placing the back plate cut in step S2 at the bottom, and then aligning the adhesive film, the middle decoration and the colored glass in step S1 upward in sequence, with the colored glass being placed with the high temperature resistant film at the top layer, and performing vacuum pressing at a temperature of 90 to 155° C., a vacuum degree of -5 to -80 MPa, and a holding time of 5 to 20 minutes;

[0010] S4. Clean and trim the vacuum pressed glass to obtain an ultra-thin laminated multi-textured colored crystal glass panel with an overall thickness of less than 5 mm.

[0011] In the technical solution of the embodiment of the present application, by selecting ultra-thin glass as the base material and rationally designing the structure of each layer of the colored crystal glass panel, and cooperating with the vacuum pressing process, the gas between the layers can be better discharged and the cross-linking strength of the layers can be improved, so as to obtain an ultra-thin interlayer multi-texture colored crystal glass panel with high overall performance, smooth pressing, and better water-blocking effect; at the same time, the color, pattern and texture effects are designed on the surface of the ultra-thin glass, and the intermediate decorations and interlayers are matched, so that the product has a stronger three-dimensional sense, higher richness, a strong sense of layering in the outer layer, and is beautiful and generous.

[0012] In some embodiments, in step S3, the holding time includes vacuuming time and laminating time, the vacuuming time is 40 to 300 seconds, and the laminating time is 120 to 840 seconds. In step S1, the ultra-thin glass is glass with a thickness of 0.1 to 3.2 mm. In step S2, the thickness of the adhesive film is 0.1 to 0.8 mm, and the adhesive film is one of EVA film, POE film, PVB film, and SGP film. The thickness of the backplane is 0.1 to 2 mm, and the backplane is a backplane made of PET or glass. The intermediate decoration is one or more of silk, cloth, film, and steel wire, with a thickness of 0.1 to 1 mm.

[0013] In this embodiment, by using tempered glass less than 3.2mm and a single-glass backboard laminated method, the middle layer is matched with decorative materials and film materials, so that the overall thickness of the product is less than 5mm. When used in household appliances, such as refrigerator panels, the weight of the appliances will be reduced, and it is also easy to assemble and carry, thereby improving the application value of the colored crystal glass panel.

[0014] In some embodiments, in step S1, the pattern processing process is one or more of transfer, dyeing, spraying, inkjet printing, screen printing, and roller coating. In step S1, the high temperature resistant film protection film is one of PET film, PL film, and PTFE film.

[0015] In a second aspect, an embodiment of the present application provides an ultra-thin laminated multi-textured colored crystal glass panel, which is prepared by the method for preparing an ultra-thin laminated multi-textured colored crystal glass panel described in any one of the above. The ultra-thin laminated multi-textured colored crystal glass panel comprises a back panel, a film layer, an intermediate decorative layer, a glass substrate, and a dyeing layer and / or a texture layer and a protective film layer arranged on the glass substrate in sequence, wherein the texture layer is arranged on the upper surface of the glass substrate, and the protective film layer is arranged on the outermost layer of the glass substrate.

[0016] In the technical solution of the embodiment of the present application, ultra-thin tempered glass and back panel single glass lamination are used, and the middle layer is matched with decorative materials and film materials. This layer structure design can be better aligned, does not require high-temperature tape fixation, and is suitable for production lines that require complete assembly and transportation, and has relatively good production stability.

[0029] Most of the existing decorative glass on colored crystal glass is made of single-piece glass by direct printing to form a decorative panel. Its disadvantages are poor appearance, no layered texture, and poor mechanical properties, which cannot meet the requirements. Colored laminated glass has the problem of being too thick and heavy, and its application scenarios are limited. In addition, the glass is only adjusted by color sheets. As a decorative material or colored crystal glass, its color and pattern are relatively monotonous and unselectable. It is not only unartistic, but also lacks decorative effects. It is also limited to use on colored crystal glass.

[0030] In order to solve the technical problems of existing colored crystal glass such as large overall thickness, heavy weight, poor color and poor performance, the present application provides an ultra-thin interlayer multi-texture colored crystal glass panel and a preparation method thereof. In the preparation process, by selecting ultra-thin glass as the substrate and rationally designing the structure of each layer of the colored crystal glass panel, and cooperating with the vacuum pressing process, the gas between the layers can be better discharged and the cross-linking strength of each layer can be improved, so as to obtain an ultra-thin interlayer multi-texture colored crystal glass panel with high overall performance, smooth pressing and better water-blocking effect; at the same time, the color, pattern and texture effect are designed on the surface of the ultra-thin glass, and the intermediate decorations and interlayer are matched, so that the product has a stronger three-dimensional sense, higher richness, a strong sense of layering in the outer layer, and is beautiful and generous.

[0031] The ultra-thin laminated multi-textured colored crystal glass panel and the preparation method thereof provided in the embodiments of the present application can be applied to, but not limited to, the fields of household appliances, building decoration, etc.

[0032] For the convenience of description, the following embodiments are described by taking a method for preparing an ultra-thin laminated multi-textured colored crystal glass panel according to an embodiment of the present application as an example.

[0033] In a first aspect, an embodiment of the present application provides a method for preparing an ultra-thin laminated multi-textured colored crystal glass panel, comprising the following steps:

[0034] S1, slicing, edge grinding and tempering the ultra-thin glass, performing pattern processing on the glass surface to obtain a coating with color and texture, and performing high temperature resistant film protection on the coating surface to obtain colored glass;

[0035] S2, cutting the middle decoration, the film and the back plate;

[0036] S3. Place the back panel cut in step S2 at the bottom, and then align the adhesive film, the middle decoration and the colored glass in step S1 upward in sequence. The colored glass is placed with the high-temperature resistant film on the top layer, and vacuum pressed at a temperature of 90 to 155°C, a vacuum degree of -5 to -80 MPa, and a holding time of 5 to 20 minutes. The holding time includes the vacuuming time and the laminating time. The vacuuming time is 40 to 300 seconds, and the laminating time is 120 to 840 seconds.

[0037] S4. Clean and trim the vacuum pressed glass to obtain an ultra-thin laminated multi-textured colored crystal glass panel with an overall thickness of less than 5 mm.

[0038] In the technical solution of the embodiment of the present application, by selecting ultra-thin glass as the substrate and rationally designing the structure of each layer of the color crystal glass panel, and cooperating with the vacuum pressing process, the gas between the layers can be discharged well, the cross-linking strength of each layer can be improved, and an ultra-thin interlayer multi-textured color crystal glass panel with high overall performance, flat pressing, and better water-blocking effect can be obtained; wherein, by limiting the vacuum degree and the time of vacuuming, it is conducive to discharging the air between the layers, so that the glass has a good appearance effect, and also ensures the cross-linking between the layers during lamination. Controlling the pressing temperature can better play the cross-linking effect of the film, which is conducive to the composite of each layer. Sufficient lamination time ensures the full effect of the film, and also makes the glass flatter, limits the increase in the overall thickness of the glass, so that it can achieve better water-blocking effect, and it is also necessary to avoid the lamination time being too long to affect the performance of the glass. In addition, this embodiment designs color, pattern and texture effects on the surface of the ultra-thin glass, matches the intermediate decoration and the interlayer, so that the product has a stronger three-dimensional sense, higher richness, and a strong sense of hierarchy and beautiful appearance.

[0039] Further, in some embodiments, in step S1, the ultra-thin glass is glass with a thickness of 0.1 to 3.2 mm. In step S2, the thickness of the adhesive film is 0.1 to 0.8 mm, and the adhesive film is one of EVA film, POE film, PVB film, and SGP film. The thickness of the backboard is 0.1 to 2 mm, and the backboard is a backboard made of PET or glass. The intermediate decoration is one or more of silk, cloth, film, and steel wire, with a thickness of 0.1 to 1 mm.

[0040] In the technical solution of the embodiment of the present application, by adopting a tempered glass less than 3.2mm and a single glass backboard laminated method, the middle layer is matched with decorative materials and film materials, so that the overall thickness of the product is less than 5mm. When used in household appliances, such as refrigerator panels, etc., it will reduce the weight of the appliances, and it is also easy to assemble and carry, thereby improving the application value of the colored crystal glass panel.

[0041] In some embodiments, in step S1, the pattern processing process is one or more of transfer, dyeing, spraying, inkjet printing, screen printing, and roller coating. In step S1, the film used for high temperature resistant film protection is one of PET, PL, and PTFE film.

[0042] Please refer to Figure 1-2As shown, in the second aspect, the embodiment of the present application provides an ultra-thin interlayer multi-textured colored crystal glass panel 100, which is prepared by the above-mentioned method for preparing an ultra-thin interlayer multi-textured colored crystal glass panel. The ultra-thin interlayer multi-textured colored crystal glass panel 100 includes a back panel 110, an adhesive film layer 120, an intermediate decorative layer 130, a glass substrate 140, and a dyeing layer 141 and / or a textured layer 142 and a protective film layer 143 arranged on the glass substrate 140, wherein the textured layer 142 is arranged on the upper surface of the glass substrate 140, and the protective film layer 143 is arranged on the outermost layer of the glass substrate 140. The dyeing layer 141 can be arranged on the upper surface or the lower surface of the glass substrate 140, such as Figure 1-2 As shown respectively.

[0043] See also Figure 3 As shown, this is a physical picture of an ultra-thin laminated multi-texture colored crystal glass panel prepared by the technical solution of an embodiment of the present application. The ultra-thin laminated multi-texture colored crystal glass panel 100 utilizes ultra-thin tempered glass plus a single glass lamination method of a back panel, and the middle layer is matched with decorative materials and film materials. This layer structure design can be better aligned, does not require high-temperature tape to fix, and is suitable for production lines that require complete assembly and transportation, and has relatively good production stability.

[0070] Although the color crystal glass panel prepared in Comparative Example 7 has an overall qualified appearance, the edges are easily concave, and it is not easy to align during processing, and high-temperature tape is required for fixing. In Comparative Example 8, the layers are not easy to align, and the slide is easily displaced, and the silk is easily deformed, and the performance of the prepared color crystal glass is relatively poor. In Comparative Examples 9 and 10, double-layer adhesive films are used.
