Description

A paste and attach membrane for glass single face attenuate

Technical Field

The utility model relates to a paste and attach membrane for glass single face attenuate.

Background

The continuous development of liquid crystal display panels requires that the display screen is lighter and thinner, the OLED panel is limited by the process, and the glass substrate cannot be thinned on two sides and can be thinned on one side. Therefore, the thinning difficulty of the OLED is higher, the surface of the protective cover needs not to be corroded by acid liquor in the production process, and meanwhile, the substrate surface needs to be soaked in the acid liquor for chemical etching. The difficulty of the process is very conceivable.

SUMMERY OF THE UTILITY MODEL

To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses an attached membrane for glass single face attenuate, glue including acid-proof membrane, isolation layer and UV, the isolation layer is attached at glass's target location, acid-proof membrane covers on the isolation layer and marginal salient in the edge of isolation layer utilizes UV glues makes acid-proof membrane edge with glass is sealed attached.

Further, the isolation layer is release paper.

Further, the isolation layer is an electrostatic film.

Furthermore, the length of the isolation layer is minus 20 plus or minus 2mm of the length of the long side of the glass, the width is minus 20 plus or minus 2mm of the length of the short side of the glass, and the thickness is 100 plus or minus 10 um.

Further, the acid-proof film is 100 +/-10 um in thickness.

The utility model discloses the beneficial effect who gains:

through the matching of the acid-proof film and the isolating layer, the adhesion area of the acid-proof film and the glass is reduced, and the film is conveniently torn after etching; the isolating layer is made of release paper, so that the isolating layer can be recycled and reused, and the cost is reduced; in addition, the isolating layer can also adopt an electrostatic film to increase the reliability of the adhesion of the acid-proof film and the glass. And during etching, two pieces of glass are oppositely and hermetically connected, so that acid is further prevented from entering to etch the cover plate surface, and loss is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The glass refers to a glass substrate which can only be thinned on one side according to the process requirements, and the glass substrate is thinned by soaking in an acid solution for corrosion.

An attaching film for thinning a single surface of glass is shown in figures 1-2 and comprises an acid-proof film 1, an isolation layer 2 and UV glue 3, wherein the isolation layer 2 is attached to a target position of glass 4, the acid-proof film 1 covers the isolation layer 2, the edge of the acid-proof film 1 protrudes out of the edge of the isolation layer, and the edge of the acid-proof film 1 is hermetically attached to the glass 4 through the UV glue 3. In the above embodiment, the adhesion area between the glass 4 and the acid-proof film 1 is reduced by the isolation layer 2, so as to facilitate the removal of the acid-proof film 1 after the thinning is completed; by sealing the edge of the acid-proof film 1 with the glass 4 through the UV glue 3, the corrosive liquid is prevented from contacting the cover plate surface of the glass 4 from the gap between the acid-proof film 1 and the glass 4 to corrode the surface of the glass 4; and the side edges of the glass 4 are protected from the acid by the UV glue 3.

In one embodiment, the isolation layer 2 is release paper; by using the release paper and utilizing the anti-sticking property of the release paper, the release paper can be conveniently torn off from the acid-proof film 1 for continuous use; meanwhile, the contact area between the acid-proof film 1 and the glass 4 can be reduced, so that the film can be torn conveniently after etching.

In one embodiment, the isolation layer 2 is an electrostatic film. The electrostatic film is adsorbed on the surface of the glass 4 by means of self static electricity, and glue is not left on the stripped surface after stripping; after the adhesion, the glass 4 is kept still relatively all the time, so that the adhesion reliability of the acid-proof film 1 and the glass 4 is improved. Therefore, if the middle part is made of a non-adhesive material, the acid-proof film 1 and the glass 4 are completely connected and fixed only by slightly gluing the edges, and the acid-proof film 1 and the glass 4 are possibly separated to a certain extent when the acid-proof film is used.

In the above embodiment, the length of the isolation layer 2 is-20 ± 2mm of the long side of the glass 4, the width is-20 ± 2mm of the short side of the glass 4, and the thickness is 100 ± 10 um.

In one embodiment, the acid-proof film 1 has a thickness of 100 ± 10 um.

When the acid-proof film is used, the sticking film is attached to the glass 4, and the acid-proof film is hermetically adhered to the glass 4 through the UV glue.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
