Description

Technical Field

[0001] The present invention belongs to the technical field of small-sized reticulated glass. More specifically, it relates to a method for preparing small-sized reticulated glass, and also relates to a small-sized reticulated glass plate member and a small-sized reticulated glass. Background Art

[0002] Currently, with the continuous expansion of the consumer electronics product market scale, the application fields of electronic product glass covers are also constantly expanding. The electronic product glass cover largely determines the display effect of the electronic product display, and its appearance quality directly determines the appearance and service performance of the electronic product. Therefore, the coating process of the electronic product glass cover becomes particularly important. At the same time, the types of glass covers are increasing rapidly with the expansion of the consumer electronics product market scale. Among them, a kind of ultra-thin flexible glass reticulated glass has been manufactured due to its excellent folding performance. In the processing technology of reticulated glass, slot extrusion of glue for coating is the main coating processing technology for existing flexible covers. However, in actual applications, the coated glass may have defects such as bubbles and wrinkles, which have an adverse impact on the product quality. Currently, since the reticulation in the middle of the reticulated glass is a through-hole, the coating step difference is too large, resulting in bubbles when coating a specified thickness at one time. These bubbles will affect the optical and mechanical properties of the middle groove area. Therefore, there is an urgent need for a new coating process to solve this problem. In summary, the main defects in the prior art are as follows: Currently, when coating an optical glue on an ultra-thin flexible reticulated glass, a process of coating to a specified coating thickness at one time is mainly used. When coating an ultra-thin flexible glass with a high step difference, this coating process will cause the generation of bubbles and wrinkles. The bubbles and wrinkles will affect the optical and mechanical properties of the ultra-thin flexible reticulated glass, resulting in a decrease in its application rate. The glass quality of the prior art has defects.

[0003] In the prior art, there is a technology with the name of "an anti-fingerprint glass cover with a reticulated effect" and the publication (announcement) number of "CN204977659U". This technology discloses an anti-fingerprint glass cover with a reticulated effect, which includes a PET protective film layer, an anti-reflection film layer, an optical glue layer, and a glass cover body stacked in sequence from top to bottom, a high-transparency ink layer, a reflective ink layer, a phosphor ink layer, a gray ink layer, and an anti-radiation layer. The anti-reflection film layer and the glass cover body are bonded together through the optical glue layer. The PET protective film layer includes a PET original film, a water glue layer, a PET release film, and a matte particle layer stacked in sequence from bottom to top. The beneficial effect of the present utility model is to provide a glass cover that not only has novelty, uniqueness, and visual impact but also can prevent fingerprints.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention is a preparation method for small-sized reticulated glass. The preparation steps of the preparation method for small-sized reticulated glass are as follows:

[0009] S2. The AB double-sided adhesive layer of the plate is attached to the glass layer. After the AB double-sided adhesive layer of the plate is attached to the glass layer of the plate, one-time coating and second degassing are carried out to form the first optical adhesive layer of the plate.

[0010] S3. After the first light curing, voids appear in the first optical adhesive layer of the plate. The second coating and third degassing are carried out on the first optical adhesive layer of the plate to form the second optical adhesive layer of the plate.

[0011] S4. After the second light curing, a small-sized reticulated glass plate is formed. The small-sized reticulated glass plate is cut to form a plurality of small-sized reticulated glasses.

[0012] The sum of the thicknesses of the first optical adhesive layer and the second optical adhesive layer of the plate falls within the set thickness range value of the optical adhesive layer of the plate.

[0013] After the second coating and degassing of the second optical adhesive layer of the plate, the second optical adhesive layer of the plate fills the voids that appear in the first optical adhesive layer of the plate.

[0014] Under the pressure of the first coating and the second coating, the optical adhesive layer fills the through holes in the middle groove area of each reticulated glass layer of the glass layer of the plate, so that the coating is uniform.

[0015] Multiple degassing in the first degassing, the second degassing, and the third degassing eliminates the fine bubbles generated during the coating process.

[0016] The first curing and the second curing use a UV curing machine.

[0017] The small-sized reticulated glass plate is cut by a cutting machine to form a plurality of small-sized reticulated glasses 6.

[0018] The present invention also relates to a small-sized reticulated glass plate member with a simple structure, which is aimed at the characteristics of small-sized reticulated glass, can solve the problems of bubbles and wrinkles generated after coating and curing, and improve the overall quality of the product. The small-sized reticulated glass plate member includes a second optical adhesive layer of the plate member, a first optical adhesive layer of the plate member, a glass layer of the plate member, an AB double-sided adhesive layer of the plate member, and a bottom plate layer of the plate member. From top to bottom, they are the second optical adhesive layer of the plate member, the first optical adhesive layer of the plate member, the glass layer of the plate member, the AB double-sided adhesive layer of the plate member, and the bottom plate layer of the plate member. After the AB double-sided adhesive layer of the plate member is bonded to the glass layer of the plate member, it is subjected to a first coating and a second degassing, and then a first light curing. Cavities appear in the first optical adhesive layer of the plate member. The first optical adhesive layer of the plate member is subjected to a second coating and a third degassing to form a second optical adhesive layer of the plate member, and the second optical adhesive layer of the plate member can fill the cavities on the surface of the first optical adhesive layer of the plate member.

[0019] The present invention also relates to a small-sized reticulated glass with a simple structure, which is aimed at the characteristics of small-sized reticulated glass, can solve the problems of bubbles and wrinkles generated after coating and curing, and improve the overall quality of the product. After the small-sized reticulated glass plate member is cut, a plurality of small-sized reticulated glasses are formed. The small-sized reticulated glass includes a second optical adhesive layer of the reticulated glass, a first optical adhesive layer of the reticulated glass, a glass layer of the reticulated glass, an AB double-sided adhesive layer of the reticulated glass, and a bottom plate layer of the reticulated glass.

In this way, after the first coating and degassing, the cavities on the surface of the first optical adhesive layer will be filled by the second optical adhesive layer formed after the second coating and degassing. At the same time, by adding a degassing step before UV curing after each coating, the generation of bubbles and wrinkles can be avoided by using two coatings of the optical adhesive. In this way, the problems of bubbles and coating wrinkles generated by one-time coating are avoided. In this way, the two-coating method has the effect of eliminating the defects generated by one-time coating. In addition, multiple degassing treatments can eliminate the fine bubbles generated during the coating process. At the same time, under the pressure of the coating, the optical adhesive can fill the through holes in the middle groove area of the glass, avoiding the problem of uneven coating.

Detailed Description of the Invention

[0030] The following further describes in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships of the various components involved, the functions and working principles of each part, etc., with reference to the accompanying drawings:

[0031] As shown in the Figure 1 - attached Figure 6 drawings, the present invention is a method for preparing small-sized reticulated glass, and the preparation steps of the method for preparing small-sized reticulated glass are as follows:

[0032] S1. The double-sided adhesive layer 1 of the plate AB is bonded to the bottom plate 2 of the plate, and the first degassing is performed on the double-sided adhesive layer 1 of the plate AB and the bottom plate 2 of the plate; S2. The double-sided adhesive layer 1 of the plate AB is bonded to the glass layer 3. After the double-sided adhesive layer 1 of the plate AB is bonded to the glass layer 3 of the plate, one-time coating and second degassing are performed to form the first optical adhesive layer 4 of the plate; S3. After the first light curing, voids appear in the first optical adhesive layer 4 of the plate. The second coating and third degassing are performed on the first optical adhesive layer 4 of the plate to form the second optical adhesive layer 5 of the plate; S4. After the second light curing, a small-sized reticulated glass plate is formed, and the small-sized reticulated glass plate is cut to form a plurality of small-sized reticulated glasses 6. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting the steps, by changing the predetermined optical adhesive layer (coating) applied to the surface of the glass layer of the plate at one time to be applied in two times, and the thickness of the two optical adhesive layers formed after the two coatings reaches the thickness of the predetermined optical adhesive coating. In this way, after the first coating and degassing, the voids on the surface of the first optical adhesive layer will be filled by the second optical adhesive layer formed after the second coating and degassing. At the same time, by increasing the degassing steps before UV curing after each coating, the generation of bubbles and wrinkles can be avoided by using two coatings of optical adhesive for coating. In this way, the problems of bubbles and coating wrinkles generated by one-time coating are avoided. In this way, the method of two coatings has the effect of eliminating the defects generated by one-time coating. In addition, multiple degassing treatments can eliminate the fine bubbles generated during the coating process. At the same time, under the pressure of coating, the optical adhesive can fill the through holes in the middle groove area of the glass, avoiding the problem of uneven coating. The method for preparing the small-sized reticulated glass described in the present invention has simple steps, and can solve the problems of bubbles and wrinkles generated after coating and curing for the characteristics of the small-sized reticulated glass, improving the overall quality of the product.

[0033] The sum of the thicknesses of the first optical adhesive layer 4 of the plate and the second optical adhesive layer 5 of the plate falls within the set thickness range value of the optical adhesive layer of the plate. After the second optical adhesive layer 5 of the plate is coated and degassed, the second optical adhesive layer 5 of the plate fills the voids that appear in the first optical adhesive layer 4 of the plate. In the above steps, changing one-time coating to two-time coating, the thickness of the optical adhesive layer formed by the two coatings meets the requirements. Moreover, more importantly, the adhesive layer formed by the second coating can eliminate the defects of the adhesive layer formed by the first coating. In this way, the quality of the finally formed product is effectively improved.

[0034] Under the pressure of the first coating and the second coating, the optical adhesive layer fills the through holes in the middle groove area of each reticulated glass layer 9 of the glass layer 3 of the plate, making the coating uniform. In the above steps, there is no need to additionally increase the rolling process, and relying on the pressure of the two coatings, it can act reliably on the product during the coating process, effectively improving the uniformity of the coating.

[0035] Multiple defoaming operations, including the first defoaming, the second defoaming, and the third defoaming, are used to eliminate the fine bubbles generated during the coating process. The first curing and the second curing are carried out using a UV curing machine. A cutting machine is used to cut the small-sized reticulated glass plate into multiple small-sized reticulated glasses 6.

[0036] The specific implementation steps of the method for preparing the glass according to the present invention include 10 steps: as shown in the appendix Figure 1 - appendix Figure 5 shown, specifically: Step 1: The bottom plate of the plate is bonded to the AB double-sided adhesive layer; Step 2: Defoaming treatment is carried out to eliminate the bubbles between the bottom plate and the AB double-sided adhesive layer and avoid causing wrinkles in the coating; Step 3: The glass layer is bonded to the AB double-sided adhesive layer; Steps 4-5: The first optical adhesive is coated to form the first optical adhesive layer, and defoaming treatment is carried out. The defoaming treatment process is before the light curing process to prevent bubbles from being cured between the first optical adhesive layers; Step 6: The UV curing machine is used to cure the first optical adhesive layer after coating and defoaming. After curing, voids will appear in the first optical adhesive layer, which is caused by the shrinkage of the glue; Steps 7-8: The second optical adhesive is coated to form the second optical adhesive layer, and defoaming treatment is carried out. The purpose of the second coating is to fill the voids generated after the first coating is UV cured and make the sum of the thicknesses of the two adhesive layers formed by the two coatings reach the predetermined thickness of the adhesive layer; Steps 9-10: The second coated optical adhesive is UV cured and cut, and the small-sized reticulated glass is peeled off.

[0037] The present invention also relates to a small-sized reticulated glass plate with a simple structure, which is aimed at the characteristics of small-sized reticulated glass and can solve the problems of bubbles and wrinkles generated after coating and curing, and improve the overall quality of the product. It includes the second optical adhesive layer 5 of the plate, the first optical adhesive layer 4 of the plate, the glass layer 3 of the plate, the AB double-sided adhesive layer 2 of the plate, and the bottom plate layer 1 of the plate. From top to bottom, they are the second optical adhesive layer 5 of the plate, the first optical adhesive layer 4 of the plate, the glass layer 3 of the plate, the AB double-sided adhesive layer 2 of the plate, and the bottom plate layer 1 of the plate; After the AB double-sided adhesive layer 1 of the plate is bonded to the glass layer 3 of the plate, after one coating and the second defoaming and then the first light curing, voids appear in the first optical adhesive layer 4 of the plate. The first optical adhesive layer 4 is subjected to the second coating and the third defoaming to form the second optical adhesive layer 5 of the plate. The second optical adhesive layer 5 of the plate can fill the voids on the surface of the first optical adhesive layer 4 of the plate. In this way, the glass quality after cutting the glass plate is good.

[0038] The present invention also relates to a small-sized reticulated glass with a simple structure, which is aimed at the characteristics of small-sized reticulated glass, can solve the problems of bubbles and wrinkles generated after coating and curing, and improve the overall quality of the product. After the small-sized reticulated glass plate is cut, a plurality of small-sized reticulated glasses 6 are formed. The small-sized reticulated glass 6 includes a second reticulated glass optical adhesive layer 11, a first reticulated glass optical adhesive layer 10, a reticulated glass layer 9, a reticulated glass AB double-sided adhesive layer 8, and a reticulated glass bottom plate layer 7. From top to bottom, they are the second reticulated glass optical adhesive layer 11, the first reticulated glass optical adhesive layer 10, the reticulated glass layer 9, the reticulated glass AB double-sided adhesive layer 8, and the reticulated glass bottom plate layer 7. The second reticulated glass optical adhesive layer 5 of the small-sized reticulated glass 6 fills the cavities on the surface of the first reticulated glass optical adhesive layer 4. In this way, the overall quality of the small-sized reticulated glass is good.

[0039] The preparation method described in the present invention has various effects. The overall process steps are simple and easy to operate; it can effectively reduce the problems of bubbles and wrinkles generated during the coating of ultra-thin flexible reticulated glass; by adding multiple defoaming processes, the coating bubbles caused by the glass step difference can be eliminated; by stepwise coating, the uneven coating caused by the through holes in the middle groove area can be avoided.

[0040] The present invention has been described exemplarily above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
