Embodiment Construction

[0019] Embodiments of the present invention will be further explained in conjunction with the accompanying drawings below. Wherever possible, the same reference numerals represent the same or similar components throughout the drawings and description. In the drawings, the shape and thickness may be exaggerated for simplification and convenient labeling. It can be understood that the components not particularly shown in the drawings or described in the specification have forms known to those skilled in the art. Those skilled in the art can make various changes and modifications according to the content of the present invention.

[0020] When an element is referred to as being "on", it can generally mean that the element is directly on other elements, or there may be other elements present in between. Conversely, when an element is referred to as being "directly on" another element, it cannot have the other element in between. As used herein, the word "and / or" includes any co...

Abstract

The present invention discloses a method for using a thermally detachable pressure-sensitive adhesive composition. The thermally detachable pressure-sensitive adhesive composition comprises 100 parts by weight (PHR) of a high molecular polymer, 0.5-3 parts by weight of a crosslinking agent, 100-200 parts by weight of solvent and 10-40 parts by weight of a plurality of heat-expandable foamed particles. The present invention adopts a two-stage adhesion control method, and is applied in a debonding process with a small heat-resistant temperature difference.

Description

technical field [0001] The present invention relates to a pressure-sensitive adhesive technology, and in particular to a method for using a pyrolysis-viscosity pressure-sensitive adhesive composition. Background technique [0002] In the prior art, pressure-sensitive adhesives generally include rubber, silica gel, and acrylic adhesives. Among them, rubber-based pressure-sensitive adhesives are relatively low in cost, but have poor temperature resistance and are prone to aging; Better, about -40°C to 300°C, but its cost is higher; acrylic pressure-sensitive adhesives are lower in cost and better in temperature resistance, about -10°C to 180°C. Regardless of the type of pressure-sensitive adhesive, when it is used in a process that requires high adhesion, it often faces the problems of residual adhesive and difficult removal. [0003] Therefore, the present invention aims at addressing the above-mentioned troubles, and proposes a method for using a thermally debonded pressure...
