Problems solved by technology

However, the adhesive strength of the double-sided pressure-sensitive tape is not high for the glass panel of the display, and it cannot achieve an excellent bonding effect; and if the bonding method of hot-melt adhesive dispensing is used, a large investment in equipment is required, and the operation is increased. process, and it is easy to cause the problem of uneven glue application
In addition, whether it is the use of the above-mentioned double-sided pressure-sensitive tape or the hot-melt adhesive dispensing method, the weak bonding cannot be solved by simple cleaning of the bonding surface and rework, and even the key components are not clean due to the cleaning of the bonding surface. Scrap directly

Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, an adhesive tape 1 for fixing a display panel includes a substrate layer 2, and a hot melt adhesive layer 4 and a pressure-sensitive adhesive layer 6 respectively arranged on both sides of the substrate layer 2. The outer sides of the pressure-sensitive adhesive layer 6 and the hot-melt adhesive layer 4 are respectively provided with a release layer 8 and a release layer 10 . The thickness of the substrate layer 2 is 0-100 mm, the thickness of the hot-melt adhesive layer 4 is 0-10 mm, and the thickness of the pressure-sensitive adhesive layer 6 is 0-10 mm. Among them, the substrate layer 2 is made of foam substrate, the hot melt adhesive layer 4 is water-based polyester, solvent-based hot melt system, the pressure-sensitive adhesive layer 6 is a glue system with pressure-sensitive adhesive properties, and the release layer 8 , The release layer 10 is made of release paper or release film respectively.

Embodiment 2

[0027] Embodiment 2: as image 3 As shown, a kind of adhesive tape for fixing the display panel, the only difference from Example 1 is that both sides of the substrate layer 2 are provided with a hot-melt adhesive layer 4, and the outer sides of the two hot-melt adhesive layers 4 are respectively provided with separate Type layer 10. During production, hot-melt adhesive is coated on both sides of the base material layer, and dried in an oven to form two hot-melt adhesive layers 4 . When in use, the release layer 10 is peeled off, and the two hot melt adhesive layers 4 are hot-pressed and bonded to the panel 1 and the panel frame 3 of the display respectively. The hot-pressing temperature is 50-200°C, the pressure is 2-10 kgf / cm2, and the time is 2-60s , to complete the fixation.

[0028] It should be noted that the above-mentioned water-based polyesters, solvent-based hot-melt systems, and glue systems with pressure-sensitive adhesive properties can all use corresponding raw...

Abstract

The invention relates to an adhesive tape for fixing display panels and a manufacturing method thereof. The adhesive tape comprises a substrate layer, and is characterized in that at least one side of the substrate layer is provided with a hot-melt adhesive layer. The hot-melt adhesive surface is directly attached to the display panel to complete hot pressing, so that the adhesive tape has the advantages of high adhesive strength and high stability and firmness. The invention omits the hot-melt adhesive potting step in the existing technical process, and thus, overcomes the defect of poor adhesive property of the oil pressure-sensitive adhesive for the panel. The hot-melt adhesive layer with the special performance of easy peeling by heating can help to easily and quickly clean the adhesive surface of the product component for re-adhesion in case of unfavorable hot pressing, thereby greatly lowering the rejection rate of the product critical components.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an adhesive tape used for fixing a display panel and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards, electronic consumer products are quite popular in daily life, resulting in the use of flat and ultra-thin display devices in large-screen smart phones, tablet computers, LCD panels, and notebook computers. rapid growth. [0003] Electronic products are assembled from processed parts. In the assembly process, not only mechanical connectors are required for fixed connection, but also various adhesive products are required for bonding. When fixing the panel and the panel frame of the display, the prior art generally adopts double-sided pressure-sensitive adhesive tapes for bonding, for example, for LCD liquid crystal display panels, double-sided acrylic resin foam pressure-sensitive adhesive tapes are used. However, the adhesive st...
