One-step preparation of the adhesive at room temperature the cylindrical mold without magnetic layered composite method

One-step preparation of one kind of molding method is not adhesive at room temperature the cylindrical magnetic layered composite material, belonging to the technical field of composite magnetic materials. Preparation process is as follows: the piezoelectric effect of piezoelectric ceramics having a sintering into a cylindrical shape, cut to the desired size, and grinding process before bonding, coating an electrode, the polarization and the like; prepared having the magnetostriction of the magnetic material powder uniformly mixed with a proportion of epoxy resin, mass fraction of epoxy resin is 7 to 15%; the mixture was mixed (the TDE) directly filled into the cylindrical piezoelectric material of the mold, at room temperature, is applied along the cylindrical axis 3 ~ 5Mpa pressure and cured for 24 to 48 hours to obtain a cylindrical bonded composite magnetic layer. In the present invention, a piezoelectric ceramic material as a mold, and demolding the mold without additional production step, the next step at room temperature to obtain an adhesive of the cylindrical shaped layered magnetic composite material, the preparation process is simple, fast, low-cost, practical strong application value advantages.
