Problems solved by technology

[0002] With the rapid development of science and technology and polymer materials, release films are becoming more and more common, and their application range is becoming wider and wider. Therefore, more and more release films appear in the market, and different colors are required to distinguish them. At the same time, it is necessary to meet the needs of customers for release films of different colors in different situations. At present, the color of the release film is relatively single, which limits the scope of use of the release film.
In addition, today's release film generally does not have anti-static function, and once there is static electricity attached to the release film during use, it is easy to stick to the surface of the object, resulting in the phenomenon that it is not easy to peel off

Embodiment 1

[0020] A preparation method of an antistatic multi-color multi-film release film is as follows:

[0021] Add 120 parts by mass of resin powder, 25 parts of auxiliary agent, 1 part of lubricant, 5 parts of color masterbatch, 1 part of antioxidant, and 4 parts of antistatic agent into the mixer for uniform mixing Finally, it is added to the twin-screw granulator extruder for granulation and extrusion to obtain modified particles, which are then added to a molding machine for compression molding to obtain a film with a film thickness of 60 microns, and then the obtained film. Corona treatment, after the treatment is complete, under the condition of 100 ℃, spray the release agent evenly on the surface of the film with a high-pressure sprayer, and the thickness is controlled at 1 micron. After drying for 15 seconds, the obtained film is Anti-static multi-color multi-film type release film.

[0022] Further, the color masterbatch is as follows: 50 parts by mass of polyurethane, 12 ...

Embodiment 2

[0031] A preparation method of an antistatic multi-color multi-film release film is as follows:

[0032] Add 110 parts by mass of resin powder, 30 parts of auxiliary agent, 2 parts of lubricant, 4 parts of color masterbatch, 1 part of antioxidant, and 4 parts of antistatic agent into the mixer for uniform mixing Finally, it is added to the twin-screw granulator extruder for granulation and extrusion to obtain modified particles, which are then added to a molding machine for compression molding to obtain a film with a film thickness of 40 microns, and then the obtained film. Corona treatment, after the treatment is complete, under the condition of 90 ℃, spray the release agent evenly on the surface of the film with a high-pressure sprayer, and control the thickness at 2 microns. After drying for 20 seconds, the obtained film is Anti-static multi-color multi-film type release film.

[0033] Further, the color masterbatch is as follows: 45 parts by mass of polyurethane, 15 parts...

Embodiment 3

[0042] A preparation method of an antistatic multi-color multi-film release film is as follows:

[0043] Add 100 parts by mass of resin powder, 20 parts of auxiliary agent, 1 part of lubricant, 4 parts of color masterbatch, 1 part of antioxidant, and 3 parts of antistatic agent into the mixer for uniform mixing Finally, it is added to the twin-screw granulator extruder for granulation and extrusion to obtain modified particles, which are then added to a molding machine for compression molding to obtain a film with a film thickness of 20 microns, and then the obtained film. Corona treatment, after the treatment is complete, under the condition of 80 ℃, spray the release agent evenly on the surface of the film with a high-pressure sprayer, and the thickness is controlled at 1 micron. After drying for 10 seconds, the obtained film is Anti-static multi-color multi-film type release film.

[0044] Further, the color masterbatch is as follows: 40 parts by mass of polyurethane, 10 p...

Abstract

The invention relates to the technical field of release film preparation, in particular to a preparation method of an antistatic multi-color multi-film release film. The antistatic multi-color multi-film release film mainly comprises 100-120 parts of resin powder, 20-30 parts of an adjuvant, 1-3 parts of a lubricant, 4-6 parts of a color master batch, 1-2 parts of an antioxidant, 3-5 parts of an antistatic agent and the like. The prepared antistatic multi-color multi-film release film has an antistatic function, static electricity is not attached to the release film in the use process, and thepeeling of the film in an environment easy to generate static electricity is effectively improved. In addition, by changing used resin powder and the color master batch, various colors and films of release film products can be prepared, and its application range is wider.
