US 12,359,374 B2 · Flame-resistant paper for radio wave absorber member and production method for same

Abstract

An object of the present invention is to provide, in particular, flame-resistant paper for a radio wave absorber member, the flame-resistant paper being unlikely to break during the production process and having favorable producibility in addition to being suitable for a radio wave absorber member and having high flame resistance. The flame-resistant paper for a radio wave absorber member according to the present invention contains pulp, aluminum hydroxide, guanidine phosphate, a binder, and a conductive substance, in which the content of the pulp is 5 to 20 mass %, the content of the aluminum hydroxide is 40 to 70 mass %, the content of the guanidine phosphate is 10 to 20 mass %, the content of the binder is 5 to 10 mass %, and the content of the conductive substance is 0.1 to 12 mass %.
