一种防气泡的导光板固定胶带

Abstract

本实用新型公开了一种防气泡的导光板固定胶带，包括底部反射固定双面胶条、硅胶条、双面胶条和撕手离型膜，底部反射固定双面胶条上端前侧沿长度方向设有硅胶条，硅胶条上端沿长度方向设有双面胶条，双面胶条上端设有撕手离型膜，底部反射固定双面胶条和撕手离型膜宽度均大于硅胶条和双面胶条，底部反射固定双面胶条未设置硅胶条后侧设有数条间隔的裁切缝，裁切缝上下贯通且向后侧贯穿底部反射固定双面胶条。本实用新型能够利用双面胶条的上端面和底部反射固定双面胶条的下端面完成贴合作业，并通过更宽的底部反射固定双面胶条以及其上的裁切缝，在增加贴合强度的同时，提供贴合过程中贴合气泡的排气途径，增加导光板固定胶带的排气功能。

Claims

1. A bubble-proof light guide plate fixing tape, characterized in that: The device includes a bottom reflective fixing double-sided adhesive strip (1), a silicone strip (2), a double-sided adhesive strip (3), and a release film (4). The bottom reflective fixing double-sided adhesive strip (1) has a silicone strip (2) along its length on the front side of its upper end. The silicone strip (2) has a double-sided adhesive strip (3) along its length on the upper end of its upper end. The double-sided adhesive strip (3) has a release film (4) at its upper end. The width of the bottom reflective fixing double-sided adhesive strip (1) and the release film (4) is greater than that of the silicone strip (2) and the double-sided adhesive strip (3). The bottom reflective fixing double-sided adhesive strip (1) without the silicone strip (2) has several spaced cutting seams (5). The cutting seams (5) are vertically continuous and extend backward through the bottom reflective fixing double-sided adhesive strip (1).

2. The air bubble preventing light guide plate fixing tape according to claim 1, characterized by: The silicone strip (2) and the double-sided adhesive strip (3) have the same width.

3. The air bubble preventing light guide plate fixing tape according to claim 2, characterized by: The width of the bottom reflective fixing double-sided adhesive strip (1) is twice that of the silicone strip (2) and the double-sided adhesive strip (3).

4. The air bubble preventing light guide plate fixing tape according to claim 2, characterized by: The width of the release liner (4) is at least twice that of the silicone strip (2) and the double-sided adhesive strip (3).

5. The air bubble preventing light guide plate fixing tape according to claim 1, characterized by: Several of the aforementioned cutting seams (5) are set at equal intervals.

6. The air bubble preventing light guide plate fixing tape according to claim 1, wherein: All of the aforementioned cutting seams (5) are arranged parallel to each other along the width direction.

7. The air bubble preventing light guide plate fixing tape according to claim 1, wherein: The ends of the bottom reflective fixing double-sided adhesive strip (1), silicone strip (2) and double-sided adhesive strip (3) are flush, and the end of the tear-off release film (4) extends and protrudes beyond the ends of the bottom reflective fixing double-sided adhesive strip (1), silicone strip (2) and double-sided adhesive strip (3).

8. The air bubble preventing light guide plate fixing tape according to claim 7, characterized by: The end of the release film (4) extends and protrudes 0.2-0.3 mm beyond the bottom reflective fixing of the double-sided adhesive strip (1), silicone strip (2) and double-sided adhesive strip (3).
