Laminated magnetic conductive plate raw material composition and production method for making laminated magnetic conductive plate

Abstract

The invention discloses a laminated magnetic conductive plate raw material composition and a production method for manufacturing a modified laminated magnetic conductive plate by utilizing the laminated magnetic conductive plate raw material composition. The laminated magnetic conductive plate raw material composition is a mixer of epoxy resin, iron powder, nano neodymium oxide and a silane coupling agent KH550, wherein the weight ratio of the epoxy resin, the iron powder, the nano neodymium oxide and the silane coupling agent KH550 is 10:2:0.5:0.13, and the proportion of the diluted epoxy resin is 50%. The problem that the iron powder in the laminated magnetic conductive plate on the market is large in proportion, easily precipitates in an epoxy resin solution and is difficult to evenly disperse, and accordingly the magnetic flow rate of the laminated magnetic conductive plate is unstable is solved. The problem that the iron powder is used for a long period of time or is easily oxidized after used in a high-temperature motor, and accordingly the magnetic conductance of the laminated magnetic conductive plate is reduced remarkably is solved.

Description

technical field [0001] The invention relates to a raw material composition of a laminated magnetic-conductive plate and a production method for producing an improved laminated magnetic-conductive plate by using the raw material composition, in particular to a method for improving a laminated magnetic-conductive plate by using rare earth materials which is superior to the traditional method of new production methods. Background technique [0002] There are many types of magnetic slot wedges, such as magnetic slot mud, molded magnetic slot wedges, pull-out magnetic slot wedges, and laminated magnetic slot wedges. The characteristics of magnetic groove mud are easy to use and high relative magnetic permeability. Its disadvantages are that it is difficult to guarantee the consistency of quality, and its strength is low, especially at high temperature. The molded magnetic slot wedge has balanced magnetic and mechanical properties, but it is dedicated to the special mold, the pro...
