Embodiment 1

[0038] The impact-resistant double-sided adhesive tape for display devices is produced by the following process: that is, the substrate layer is formed from a polyethylene terephthalate film with a thickness of 50 micrometers, and one side of the substrate layer is applied with a doctor blade Method: 100 parts by weight of acrylic resin mixture (polymerized by 100 parts by weight of n-butyl acrylate, 90 parts by weight of 2-ethylhexyl acrylate and 10 parts by weight of acrylic acid, with a weight average molecular weight of 700000), 1 A mixture of parts by weight of foaming agent (MSH-320 from SDI), 1 part by weight of curing agent (isocyanate) and 100 parts by weight of solvent (methyl ethyl ketone) is applied to a thickness of 90 microns and heated at 170°C. Foaming is carried out under the temperature condition of 100 microns to form a foaming adhesive layer with a thickness of 100 microns, and the acrylic resin mixture of 100 parts by weight (by 100 parts by weight of norma...

Embodiment 2

[0040] The impact-resistant double-sided adhesive tape for display equipment is produced by the following process: that is, the substrate layer is formed from a polyethylene terephthalate film with a thickness of 50 micrometers, and the two sides of the substrate layer are coated by a doctor blade method. By 100 parts by weight of acrylic resin mixture (polymerized by 100 parts by weight of n-butyl acrylate, 90 parts by weight of 2-ethylhexyl acrylate and 10 parts by weight of acrylic acid, the weight average molecular weight is 700000), 1 weight Parts of foaming agent (SDI MSH-320), 1 part by weight of curing agent (isocyanate) and 100 parts by weight of solvent (methyl ethyl ketone) are mixed and coated to a thickness of 90 microns at a temperature of 170 ° C The foaming was carried out under the following conditions to form a foamed adhesive layer with a thickness of 100 micrometers.

Abstract

The disclosure relates to an impact-resistant double-sided tape for a display device and, more particularly, to an impact-resistant double-sided tape for a display device comprising: a base layer; a foam adhesive layer formed on one surface of the base layer and formed of an acrylic foam; and an adhesive layer formed on the other surface of the base layer. As the impact-resistant double-sided tapefor a display device having the aforementioned structure is provided with a foam adhesive layer having excellent impact resistance, the impact-resistant double-sided tape for a display device suppresses generation of a crack on a glass surface of a display device due to an external impact, and has an excellent waterproof effect.

Description

technical field [0001] The present invention relates to an impact-resistant double-sided adhesive tape for display devices, and more specifically, relates to a foamed adhesive layer formed with excellent impact resistance, which can suppress the occurrence of cracks on the glass surface of a display device due to external impact , and exhibits an excellent waterproof effect of the impact-resistant double-sided adhesive tape for display equipment. Background technique [0002] Generally, in order to bond and fix many kinds of display panels, electronic parts, etc. in a display device, a double-sided adhesive tape is used, and the double-sided adhesive tape is sandwiched between the display window and the display module to play the role of bonding these. In this way, the double-sided adhesive tape performs the fixing of the edge of the display, etc., while preventing the intrusion of external impurities, etc., and prevents the light irradiated from the light source, etc. insta...
