High stability shading adhesive tape and processing method thereof

Abstract

The invention discloses a high stability shading adhesive tape and a processing method thereof. The high stability shading adhesive tape comprises at least one shading tape, at least one hot melt adhesive parallel to the extension direction of the shading adhesive and transparent double faced adhesive tapes located on the outer sides of two ends of the hot melt adhesive. One adhesive sides of theshading adhesive, the hot melt adhesive and the double faced adhesive tape are covered by a supporting film while the other adhesive faces are covered by a handle film, and the peeling force of the handle film is greater than that of the supporting film. According to the scheme, the high stability shading adhesive tape integrates the shading adhesives and the hot melt adhesive effectively into anintegrated structure, and a plurality of adhesives can be attached by one-time operation, so that the efficiency is high. The defect that the weather resistance of the shading adhesives is poor is supplemented by means of the characteristics of the hot melt adhesive fully, so that stable bonding is guaranteed, and the probability of degumming the shading adhesives is avoided. By adding the doublefaced adhesive tape, the hot melt adhesive at constant temperature clings to a to-be-adhered element stably during attachment, and the position precision is guaranteed, thereby providing guarantee tobonding the hot melt adhesive in a follow-up process, and the pasting difficulty is reduced.

Description

technical field [0001] The invention relates to the field of electronic product accessories, in particular to a high-stability light-shielding adhesive tape and a processing method thereof. Background technique [0002] With the rapid development of the electronics industry, the lightweight and thinning of electronic products such as notebooks, smart phones, PADs, car navigation, and driving recorders has become the mainstream trend, which leads to the lightweight and thinning of various parts used in their production. Thinning is imperative. [0003] Shading is a problem that is often faced in the screen assembly process of various electronic products. Generally, it is realized by light-shielding glue. On the one hand, the light-shielding glue is used as glue for bonding two components, and on the other hand, it provides the function of shielding light , but ordinary shading adhesives have average weather resistance and are easily affected by environmental factors, and the...

[0003] Shading is a problem that is often faced in the screen assembly process of various electronic products. Generally, it is realized by light-shielding glue. On the one hand, the light-shielding glue is used as glue for bonding two components, and on the other hand, it provides the function of shielding light , but ordinary shading adhesives have average weather resistance and are easily affected by environmental factors, and there may be a risk of degumming of the components connected to them

[0004] Hot-melt adhesive is an adhesive that is not affected by temperature and humidity and has a long life. However, hot-melt adhesive remains solid at room temperature and has no stickiness, so it is difficult to integrate it with light-shielding adhesive.
