The study of modified epoxy resin to bonded NdFeB magnet properties

　　Using modified epoxy resin as binder, make bonded NdFeB magnets under different process conditions, and its properties are studied.

　　The results show that, the performance of modified epoxy resin bonded NdFeB magnets is higher than traditional epoxy resin bonded NdFeB magnets, the molding temperature 130 ℃, pressure holding time 2min, curing time, curing temperature 120℃120min prepared by the magnet, whose magnetic performance is the best.

　　Since from eighty time metaphase, people have studied many binder material, such as a magnetic polymer compound epoxy resin ( thermoplastic ) ( thermosetting ), phenolic resin, nylon, PPS, polyethylene, rubber and metal with low melting point Bi, Sn, Pb, Zn, Al etc.. Liu Ying and other people studied the influence of two metallocene polymer iron powder for bonded permanent magnetic composite material performance. Chen Debo and other people studied the influence of the content of epoxy resin for the properties of the magnets, the results show that adhesive content is 2.
