EPOXY RESIN FOR ELECTROMAGNETIC WAVE INTERFERENCE PREVENTION, METHOD FOR PREPARING THE SAME, AND INDUCTANCE COMPONENT FOR ELECTROMAGNETIC WAVE INTERFERENCE PREVENTION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a epoxy resin for electromagnetic wave interference prevention which exhibits an excellent electromagnetic wave interference preventing effect, a method for preparing the resin, and an application method of an inductance component for electromagnetic wave interference prevention.;SOLUTION: Ferrite powder already sintered is polished to be made fine, a small amount of epoxy resin is added to the powder, the epoxy resin main agent as an adhesive and a curing agent are added to the powder, and are stirred. Thereby, the resin is quickly hardened and a gel A having a good heat resistance and excellent acid and alkaline resistances is formed. When such gel is directly coated on each member according to the high frequency of a communication device material or is applied to sealing an inductance component, the sensitivity of the inductance component can be increased to double or more, and the influence of the component by noise in the air can be avoided.;COPYRIGHT: (C)2005,JPO&NCIPI
