Abstract

The invention discloses an easy-to-rework foam dual-layer adhesive tape for assembling a television. The dual-layer adhesive tape comprises a thermoplastic polyurethane layer, a PU elastic layer and a PET layer, wherein the upper surface of the thermoplastic polyurethane layer is coated with a first acrylic pressure-sensitive adhesive layer, the lower surface of the thermoplastic polyurethane layer is bonded with the PU elastic layer by virtue of a second acrylic pressure-sensitive adhesive layer, the lower surface of the PU elastic layer is provided with the PET layer, and the outer surface of the PET layer is coated with a third acrylic pressure-sensitive layer. The easy-to-work foam dual-layer adhesive tape is simple in structure, high in strength, good in elasticity and toughness, high in heat conductivity, good in bonding performance, excellent in aging resistance, suitable for assembling the television and capable of improving the bonding performance after the assembly.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an easy-to-rework foam double-layer adhesive tape for TV assembly. Background technique [0002] Foam tape is made of EVA or PE foam as the base material, coated with solvent-based (or hot-melt) pressure-sensitive adhesive on one or both sides, and then coated with release paper.
