It must be said %. If the content is less than 10% by weight, the effect of suppressing dust generation will be small.
A large amount of coarse powder falls off, making it unsuitable for the purpose of use of the present invention. On the other hand, when the content exceeds 50% by weight, the polymer resin cannot fully enter the paper layer and a thick resin film is formed on the surface of the paper, which not only obscures the tetraelectric property but also impregnates the paper layer. ,
Otherwise, blocking occurs in the rolled state during coating, making it unsuitable for the purpose of use. In addition, the electrical resistance value of the conductive paper obtained in this way is such that the volume resistance value is 108 Ω・α or less (preferably 10 7 Ω・m or less) when the purpose is antistatic property, and the electromagnetic shielding property is 10 Ω・α or less (preferably 10 7 Ω・m Objective 9
For the 7th case, it is desirable that the resistance is 102 Ω·m or less (preferably 101 Ω·m L or less). However, depending on the intended use of the box assembly, the surface resistance value may be more important than the volume resistance value.
