力を付与したポリプロピレン系フィルムに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention makes it possible to change the location and repeat pasting without using adhesives, and to prevent pasting that occurs after peeling. The present invention relates to a polypropylene film that does not leave traces or contaminate adherends and has an electrostatic adhesive force that provides excellent workability and durability.

たシ、使用場所に限定を受ける等の欠点がある。Most of the conventional methods of adhering (pasting) synthetic resin films are the use of adhesives. Due to the difficulty, it can only be used once, and the same item cannot be pasted in different locations or repeated. In addition, after peeling off, there are drawbacks such as the fact that the adhesive leaves traces when pasted on the surface, contaminating the adherend, requiring cleaning treatment after use, and being limited in the location of use.

プロピレン系フィルムを提供するものである。Therefore, we are trying to provide a polypropylene film that has a long-lasting electrostatic adhesive force.
Polypropylene films have excellent physical properties such as transparency, gloss, strength, and stiffness, and are easy to manufacture into ultra-thin films by extrusion processing. However, because they are non-polar polymers, they suffer from charge attenuation due to contact and friction. [Objective of the Invention] In view of these points, the present invention aims to maintain the excellent physical properties of Bo-11 propylene and to create a material that maintains the long-lasting electrostatic adhesion force. The present invention provides a polypropylene film having the following properties.

果があった。The reason why the propylene resin content is set at 70 to 5 ii% is to ensure that the properties of the resin are not deteriorated.In fact, the modified propylene resin gives the film sustained electrostatic adhesion. The reason why the blending weight is 5 to 30% is that if the weight ratio is less than 5%, the electrostatic adhesion force is small and the effect of addition cannot be obtained.
This is because if the weight ratio exceeds 0, the properties of polypropylene will be significantly reduced and it will be shattered. (Example) Propylene resin 70 weight ratio (commercial film grade)
A composition obtained by adding necessary amounts of an oxidation preventive agent, an ultraviolet absorber, etc. to 100 parts by weight of a resin composition consisting of 30i weight percent of a modified propylene resin (butyl methacrylate graft modification 5%) was extruded with a T-die, and a 20μ A film was obtained. [Effect] When this film was triboelectrified and adhered to a window glass board and the duration was measured, it remained attached for more than 30 days.
In the case of a film made only of propylene resin, it fell off in 5 days, but the film according to the present invention was more than 6 times more effective.

ため分極電荷の消失が遅くなるためと考えられる。This is because α,β-unsaturated carboxylic acid derivatives have dipoles in their side chains, and the grafted poly-11propylene modified with these has the characteristic of moving independently of the main chain, while the group at the end of the side chain This is thought to be due to the fact that the movement tends to be restricted due to steric hindrance, which slows down the disappearance of polarized charges.
