Abstract
The invention provides a magnetic material. The magnetic material comprises the following raw materials in parts by weight: 15-35 parts of ferric oxide, 10-25 parts of silicon dioxide, 5-10 parts of zinc oxide, 3-8 parts of boric oxide, 12-25 parts of graphene, 8-15 parts of epoxy resin, 2-8 parts of aluminium oxide, 2-5 parts of cobaltous oxide, 8-20 parts of calcium carbonate, 1-5 parts of dispersing agent, 2-12 parts of binder and 1-3 parts of wetting agent. The magnetic material provided by the invention is excellent in magnetism, stable in performance, good in elasticity and tensile property, high in mechanical strength, high in impact resistance, high in high-temperature resistance, and wider in application range without affecting the environment.
Description
Technical field
The present invention relates to metal electron Material Field, be specifically related to a kind of magnetic material.
Background technology
Magnetic material, usually said magnetic material refers to ferromagnetic substance, is ancient and purposes functional material very widely, and the magnetic of material before 3000 just be familiar with by people and apply, such as ancient Chinese native magnet is as compass.Modem magnetic materials has been used among our life widely, such as, permanent magnetic material is used as motor, is applied to the core material in transformer, as the magneto optical disk that memory uses, and computer magnetic recording floppy disk etc.Large bit information is said, magnetic material is closely related with the every aspect of informationization, automation, electromechanical integration, national defence, national economy.And it has been generally acknowledged that, magnetic material refers to the material that directly or indirectly can be produced magnetic by transition element iron, cobalt, nickel and alloy thereof etc.Magnetic material can be divided into soft magnetic material and retentive material by the difficulty or ease of degaussing after magnetization.Easily remove the material of magnetic after magnetization soft magnetic material, be not easy the material of degaussing retentive material.Soft magnetic material remanent magnetism is less in general, and retentive material remanent magnetism is larger.
The major advantage of magnetic material is: density is little, impact strength is large, goods can carry out cutting, hole, weld, the processing such as lamination and embossing, and can not be chipping when using, be easy to be processed into that dimensional accuracy is high, the goods of thin-walled, complicated shape, present composite magnetic gets more and more as people are paid attention to, and is a kind of up-and-coming basic function material.Along with the extensive use of magnetic material, increasing field needs to use magnetic material, and the requirement of magnetic material is also just more and more higher, but current existing magnetic material elasticity and draftability very poor, and affect environment.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide the magnetic material that a kind of magnetic is strong, mechanical strength is high.
The present invention is achieved through the following technical solutions:
A kind of magnetic material, comprise the raw material composition of following parts by weight: iron oxide 15 ~ 35 parts, silica 10 ~ 25 part, 5 ~ 10 parts, zinc oxide, boron oxide 3 ~ 8 parts, Graphene 12 ~ 25 parts, epoxy resin 8 ~ 15 parts, 2 ~ 8 parts, aluminium oxide, cobalt oxide 2 ~ 5 parts, 8 ~ 20 parts, calcium carbonate, dispersant 1 ~ 5 part, 2 ~ 12 parts, adhesive and wetting agent 1 ~ 3 part.
