Radio wave-absorbing paint

Abstract

Abstract PURPOSE: The titled paint preventing a radio → wave such as a microwave or communication electrical wave from reflecting, which is prepd. by dispersing ferrite of specified particle size in the coat constitutent of a paint. CONSTITUTION: A calcined ferrite alone or a composite thereof such as Ni-Zn ferrite of particle size 1W100μ corresponding to the frequency of an electrical wave to be absorbed is dispersed in an oil paint, water paint, synthetic resin- base paint, etc. EFFECT: It is possible to absorb an electrical wave according to the frequency characterics and to effect safe voyage, exclusion of electrical wave trouble, elimination of electrical wave disturbunce, etc. by the application of the paint to the surface of a construction, building, etc. COPYRIGHT: (C)1982,JPO&Japio
