Problems solved by technology

However, the illumination brightness of yellow light is weaker than that of ordinary white light with the same power. Many defects that need to be detected by human eyes, such as appearance flaws and tiny cracks, are often difficult to find, resulting in a high defect rate. At the same time, because the light is yellow, many color difference problems are often It was only discovered after the entire yellow light process was completed, and then it needed to be reworked from scratch, wasting a lot of production capacity

Abstract

The invention discloses a blue ray and ultraviolet absorption adhesive tape and glue and preparation method thereof. The adhesive tape comprises a base material A, a blue ray and ultraviolet absorption adhesive layer, a base material B, a pressure-sensitive adhesive layer and a release film sequentially from top to bottom. The blue ray and ultraviolet absorption adhesive layer is formed by a blueray absorbent, an ultraviolet absorbent, acrylate resin and tackifying resin. The preparation method includes: coating two sides of the base material B with the blue ray and ultraviolet absorption adhesive layer and the pressure-sensitive adhesive layer respectively, drying through a drying tunnel, adhering the base material A on the blue ray and ultraviolet absorption adhesive layer of the base material B in a take-up stage, and laminating the release film on the pressure-sensitive adhesive layer. By the blue ray and ultraviolet absorption adhesive tape, blue ray and ultraviolet protection can be quickly provided for photosensitive materials in a processing process of optical and electronic devices, damages of the materials in a conventional workshop illumination environment are avoided,and defects caused by illumination are reduced.

Description

technical field [0001] The invention discloses a blue light-ultraviolet absorbing adhesive tape and a preparation method thereof, belonging to the field of adhesives. Background technique [0002] In the optics and electronics industry, there are many devices or processes that need to avoid exposure to ultraviolet light and some blue light. For example, in the production process of liquid crystal displays, touch screens and flexible circuit boards, a large number of photolithography processes are used, and a large number of photosensitive etching inks or photosensitive etching films are used in this process; In the production process of the group, a large amount of UV adhesive tape is used; in the screen bonding process, a large amount of UV curing optical glue is used; in the production process of optical lenses, when many photosensitive lenses are not finished with anti-ultraviolet coating, It is also necessary to strictly avoid direct exposure to ultraviolet and blue lig...
