Description
Technical Field
The invention belongs to an adhesive tape and preparation thereof, and relates to an acid-alkali-resistant antistatic high-temperature adhesive tape and a preparation method thereof. The acid-alkali-resistant antistatic high-temperature adhesive tape is suitable for the manufacturing and cleaning processes of electronic product circuit boards, plays a role in protection, and is particularly suitable for the field of cleaning aluminum plates or copper plates under the conditions of strong acid and alkali.
Background
With the continuous development of economy and the continuous improvement of the requirements of people on living level, the information technology has a rapid development. The adhesive tape technology has also penetrated into various industries, and in the fields of 5G electronics and panels, cleaning of electronic product circuit boards, protection and fixation in the manufacturing process of parts, and shielding processes of printed circuit boards and high-temperature treatment, surface parts of a large number of glass plates, aluminum plates, copper plates and other plates need to be protected and sealed, some plates need to be produced under harsh conditions (130 ℃ high temperature and boiling acid and alkali solution), and the adhesive tape used after the manufacturing process is finished can be easily torn off and cannot generate electrostatic action, so that the adhesive tape used is not influenced by temperature, acid and alkali solution and static electricity. The base material and the adhesive selected by the prior adhesive tape have many problems, and in the prior art, the commonly used protective adhesive tape is a polyvinyl chloride (PVC) electrical insulating adhesive tape, which is also called as a PVC electrical adhesive tape. Although the PVC film has good toughness, ductility and the like, the PVC adhesive tape has some defects, contains harmful substances such as halogen and the like, can cause certain harm to the environment and people, is easy to deform when heated, and has limited production process; when organic silicon is used in the adhesive, the heat resistance is good, but the silicon loss phenomenon is often accompanied, but the heat resistance of the acrylate is generally poor, the thermo-oxidative aging resistance is poor, the adhesive force gradually increases along with the temperature increase, the final stripping difficulty is large, and particularly in a boiling acid-base solution, the edge penetration is easily caused. Therefore, the protection of the metal plate materials such as aluminum plate, copper plate, etc. is adversely affected.
The prior literature reports that: the Jiangsu Asialong digital science and technology limited company develops a composite resin-based acid and alkali resistant adhesive tape and a preparation method thereof, has better acid and alkali resistance, and can replace polyvinyl chloride (PVC for short) electric insulating adhesive tapes; however, the halogen contained in the product has certain harm to the environment and human body, and has poor acid and alkali resistance and poor practicability.
