Abstract

The invention belongs to the technical field of fixing of display screens of electronic and electrical products and especially relates to a screen sealing adhesive tape and a production process thereof. The screen sealing adhesive tape comprises a TPU film, a foam base material and a black PET film, wherein the TPU film, the foam base material and the black PET film are bonded and fixed through external adhesives, the outer surface of the TPU film and the outer surface of the black PET film are coated with acrylic glue, and the outer side of the black PET film is bonded and fixed through the acrylic glue. The adhesive tape has good detachable performance, is easy to rework and low in rework cost, can be split by using a PET film or a PC film with a thickness of more than 0.1 mm, and cannotcause a situation that a pasted object of a client cannot be reworked or is scrapped when being detached; by using the soft high-performance polyethylene foam base material, the adhesive tape has favorable impact resistance and adhesion effect, can be used for firmly adhering glass, PC, metal and plastic, presents favorable adhesion property, shock resistance, aging resistance and high sealing property for the plastic material, has ultrahigh adhesion property, and shows favorable adhesion durability in high / low-temperature environments.

Description

technical field [0001] The invention belongs to the leading technical field of fixing display screens of electronic and electrical products, and in particular relates to a screen sealing adhesive tape and a production process thereof. Background technique [0002] Screen sealing adhesive tape is used for bonding and fixing electronic display screens. It is widely used in the use of screen sealing screens, such as mobile phones, computers and tablet computers. It has a good use effect. With the continuous development of society With the development of the world, people's demand for screen sealing screens is gradually increasing, and the demand for screen sealing adhesive tapes is also gradually increasing. However, the existing screen sealing adhesive tapes cannot meet people's needs, so more convenient to use screen sealing adhesive tapes are needed. [0003] Widely used in the bonding and fixing of display screens of electronic and electrical products, such as TVs, mechanic...
