Combined double-sided adhesive tape structure and method

Abstract

The invention relates to the technical field of mutual sticking of multiple metals and plastics, and in particular relates to a combined double-sided adhesive tape structure and a production method thereof. The combined double-sided adhesive tape structure comprises a pressure-sensing double-sided adhesive tape, a hot-pressed double-sided adhesive tape, a single-side adhesive tape and transfer release paper, wherein the upper layer is a single-side adhesive tape layer, the sticky surface of the single-side adhesive tape is downward, a self-release paper layer is connected below the single-side adhesive tape layer, an adhesive tape layer is connected below the self-release paper layer, a transfer releaser paper layer is connected below the adhesive tape layer, the adhesive tape layer comprises the pressure-sensing double-sided adhesive tape and the hot-set double-sided adhesive tape, and the release paper is arranged above each of the pressure-sensing double-sided adhesive tape and the hot-set double-sided adhesive tape. The combined double-sided adhesive tape structure is convenient to operate, a dispensing device is not required, the combined double-sided adhesive tape structure can be directly attached on a product to be stuck, the adhesive overflow quantity is very small, the combined double-sided adhesive tape structure has no peculiar smell and can not cause air pollution or bodily harm, and the hot-pressing time is short; reheating is irreversible and the separation of a cemented part can be avoided; and the combined double-sided adhesive tape structure can be directly sent to a flow line for continually performing the next process step operation after hot pressing.

Description

[technical field] [0001] The invention relates to the technical field of mutual bonding of various metals and plastics and the technical field of adhesive tape production, in particular to a combined double-sided adhesive tape structure and method. [Background technique] [0002] The mutual bonding of various metals and plastics is now generally used to add two-component glue on the materials to be bonded with an XY-TABLE dispenser. This technology has the following disadvantages: [0003] Dispensing must be done on the dispensing machine, which takes a long time to cure. After gluing, it needs to stand still for 24 hours before proceeding to the next process; the glue will be liquefied in reverse after being heated, resulting in the separation of the glued parts; the smell is difficult to remove after the glue overflows, which is not beautiful. And the glue that this technology adopts needs to use curing agent to solidify, and the smell of curing agent volatile matter is ve...

AI Technical Summary

Problems solved by technology

[0006] Simple double-sided tape cannot be well applied to products with different bonding materials;

[0007] The heat-pressed adhesive tape cannot be fixed on the product to be bonded as well as dispensing during pre-bonding, resulting in inaccurate positioning;

[0008] In the bonding of concave and convex surfaces, the double-sided tape cannot well fill the gaps in the bonding of concave and convex surfaces, so that the bonding strength is not high, etc.
