Abstract

The invention discloses a PE foam double-sided adhesive tape and a preparation method thereof. The PE foam double-sided adhesive tape is characterized in that the PE foam double-sided adhesive tape sequentially comprises a 10-50 [mu] m pressure-sensitive adhesive layer, a 80-400 [mu] m PE foam layer, a 10-50 [mu] m pressure-sensitive adhesive layer and a 50 [mu] m release layer from top to bottom; the pressure-sensitive adhesive is an acrylic pressure-sensitive adhesive; the PE foam layer is a foaming layer of foaming polyethylene; and the release layer is a double-sided release film. The PE foam double-sided adhesive tape provided by the invention is better in adhesive force, initial adhesive force and high-temperature retentivity, and more excellent in aging resistance and waterproof performance.

Description

technical field [0001] The invention relates to the technical field of electronic adhesive products, in particular to a PE foam double-sided adhesive tape and a preparation method thereof. Background technique [0002] Foam double-sided tape is a double-sided tape with foam as the base material and coated with the same or different types of pressure-sensitive adhesive on both sides. It has excellent sealing performance, good filling performance, good cushioning performance, strong adhesion, and good stickiness. It has a wide range of applications in household appliances, instrumentation, automobile industry, battery industry and other fields. Due to the particularity of the application field of industrial foam double-sided tape, the basic performance requirements of the tape, including adhesion, initial adhesion and holding power, are usually high, and traditional foam double-sided tape cannot meet the above requirements. Therefore, it is imperative to develop double-sided ...
