Problems solved by technology

Because the base material of ordinary release film is polyester material, which is an insulator, it is easy to generate static electricity in the process of winding and unwinding. Light static electricity will cause dust to be absorbed and affect the quality of post-processing. Heavy static electricity will cause contact with it. Electronic components are damaged by high voltage discharge

Abstract

The invention discloses a front and back double-sided anti-static composite release film which is characterized by sequentially comprising a front release agent coating layer (1), a front anti-static layer (2), a base material original film layer (3), a back anti-static layer (4) and a back release agent coating layer (5) from top to bottom; the thickness of the base material original film layer (3) is 30-70 [mu]m; the thicknesses of the front anti-static layer (2) and the back anti-static layer (4) are 15-25 [mu]m; and the thicknesses of the front release agent coating layer (1) and the back release agent coating layer (5) are 4-8 [mu]m. The front side and the back side of the front and back double-sided antistatic composite release film have antistatic functions, charge accumulation on the release film is avoided, the release film can be applied to the electronic industry, and static electricity generated by the release film is prevented from breaking down a circuit board of an electronic element.

Description

technical field [0001] The invention belongs to the technical field of release films, in particular to a double-sided antistatic composite release film. Background technique [0002] The release film refers to the film whose surface energy can be distinguished. The release film is not sticky or slightly sticky after contacting with specific materials under limited conditions. It is widely used in electronic power, IT display screens, mobile phones, LCD / PDA, medical, home appliance manufacturing, anti-counterfeiting materials, semiconductors, automobiles, nameplates, ceramic sheet manufacturing, adhesive tape production and die-cutting industries. [0003] With the development of LCD, LED, PC, mobile phone and other industries, the demand for release film is increasing day by day, and the requirements are getting higher and higher. One of them is that the release film has antistatic function. Since the base material of ordinary release film is polyester material, which is a...
