Description

Anti-static and Anti-corrosive Film < RTI ID = 0.0 >

The present invention relates to a plastic film containing antistatic and anti-rust functions.

When parts and materials containing metals are packed, static electricity, corrosion, and foreign matter contamination are generated. Therefore, additional loss is increasing due to quality defects during packaging. Particularly, automobile parts including electronic circuits are increasingly suffering from secondary damage caused by static electricity as well as corrosion, and there is an increasing demand for antistatic and corrosion prevention functions in packaging. Demand for anti-static and anti-rust film to prevent malfunctions of electronic circuits, reduce contamination of foreign substances, prevent corrosion of electronics or mechanical parts by giving anti-static function and anti-rust function simultaneously to packing containers .

Generally, methods for lowering the surface resistance by adding 1) surfactant, 2) carbon black, CNT, or 3) metal filler are used to impart antistatic properties. In the case of a surfactant, static electricity accumulated through moisture in the air is reduced, and antistatic performance is exhibited. Therefore, moisture can not be used because it interferes with the anticorrosive function. Carbon black or CNT is limited in its use because of the generation of ultrafine dust of carbon and black and opaque. It is also used as a metal filler (metal powder such as aluminum, silver, copper, nickel, TiO ₂ , ZnO ₂ , SnO ₂ , ZnS, BaSO ₄ Etc.) are also limited in the use of electronic components due to the generation of foreign substances. In addition, these antistatic additives cause mechanical properties such as impact strength of the plastic resin itself to be deteriorated, and the final plastic film product is limited in use.

Various methods such as anti-corrosive oil, grease, painting, plating, dehumidifying agent, or vacuum packaging are used to prevent corrosion. In view of limitations in use, workability and post-treatment process, Much research is underway.

If the plastic resin can realize both antistatic and anticorrosive functions, it is expected to be the most innovative packaging material.
