| 简介 |
The invention relates to a method for the production of a permanently magnetic article using a polymeric carrier material with magnetic fillers filled hot vulcanized silicone rubber based on a from at least one starting material, wherein the at least one starting material with hard magnetic ferrite particles rare-earth metal particles[...] before vulcanization and/or the as magnetic fillers mixed and subsequently the homogenized mixture is homogenized and introduced into a mold cavity by means of a temperature-controlled worm is crosslinked and with the introduction of heat by vulcanization in the mold cavity under formation of the shaped part, wherein a static magnetic field is generated during the crosslinking in the mold cavity in the cross-linked silicone rubber and/or magnetized and the magnetic fillers are aligned. |
