Abstract
The invention discloses a magnetic composite metal material which comprises a magnetic material layer, a synthetic rubber layer and an engineering plastic layer, wherein the magnetic material layer is made from magnetic alloy, the synthetic rubber layer is made from nitrile rubber, and the engineering plastic layer is made from polycarbonate; and lead-tin alloy accounts for 30-40% of the weight of the main body of the composite metal material, aluminum oxide ceramic accounts for 28-32% of the weight of the main body of the composite metal material, and asbestos accounts for 30-39% of the weight of the main body of the composite metal material. The magnetic composite metal material has the characteristics of being good in magnetism and self-lubrication, excellent in impact toughness, etc.
Description
Technical field
The present invention relates to a kind of metal material, relate in particular to a kind of magnetic composite material.
Background technology
Composite is a kind of mixture.All bring into play very big effect in a lot of fields, replaced a lot of traditional materials.Composite is divided into metal and metallic composite, nonmetal and metallic composite, nonmetal and nonmetallic composite by its composition.Be divided into again by its design feature: 1. fibre reinforced composites.Various fibre reinforcements are placed in the matrix material be composited.As fibre reinforced plastics, fibreglass-reinforced metal etc.2. interlayer composite material.Surfacing and core that do as one likes matter is different combine.Common plane materiel intensity height, thin; Core light weight, intensity are low, but have certain rigidity and thickness.Be divided into two kinds of solid interlayer and honeycomb interlayers.3. fine granule composite materials.Hard particulates is uniformly distributed in the matrix, as strengthened dispersion alloy, cermet etc.4. hybrid composite.Mixed in a kind of matrix phase material by two or more wild phase material and to constitute.With common single wild phase composite ratio, its impact strength, fatigue strength and fracture toughness significantly improve, and have special hot expansibility.Be divided into that interlaminar hybrid, interlayer mix, sandwich mixes, in the layer/interlayer mixes and superhybrid composite.Composite sixties, for satisfying the needs of sophisticated technology material therefors such as Aero-Space, successively developing and produced with high-performance fiber (as carbon fiber, boron fibre, aramid fiber, silicon carbide fibre etc.) is the composite of reinforcing material, its specific strength is greater than 4 * 106 centimetres (cm), and specific modulus is greater than 4 * 108cm.In order to distinguish mutually with first generation galss fiber reinforced resin composite, this composite is called advanced composite material.Press the matrix material difference, advanced composite material is divided into resin-based, Metal Substrate and ceramic matric composite.Its serviceability temperature reaches 250～350 ℃ respectively, more than 350～1200 ℃ and 1200 ℃.Advanced composite material also can be used as functional material except as the structural material, but these material shortage magnetic, characteristic such as self lubricity is poor, impact flexibility is not strong.
Summary of the invention
The object of the present invention is to provide a kind of magnetic composite material, have characteristics such as magnetic, self lubricity are good, impact flexibility excellence.
Technical scheme of the present invention is: a kind of magnetic composite material, described magnetic composite material comprises magnetic material layer, synthetic rubber layer and engineering plastics layer, described magnetic material layer is magnetic alloy, described synthetic rubber layer is acrylonitrile-butadiene rubber, described engineering plastics layer is Merlon, described terne metal accounts for the 30%-40% of composite material body weight, described aluminium oxide ceramics accounts for the 28%-32% of composite material body weight, and described asbestos account for the 30%-39% of composite material body weight.
In a preferred embodiment of the present invention, described magnetic alloy comprises iron, cobalt, nickel and yttrium.
In a preferred embodiment of the present invention, described terne metal accounts for 38% of composite material body weight, and described aluminium oxide ceramics accounts for 28% of composite material body weight, and described asbestos account for 34% of composite material body weight.
A kind of magnetic composite material of the present invention has characteristics such as magnetic, self lubricity are good, impact flexibility excellence.
Description of drawings
Accompanying drawing 1 for magnetic composite material one preferred embodiment of the present invention main TV structure schematic diagram.
The mark of each parts is as follows in the accompanying drawing: 1, magnetic material layer, 2, synthetic rubber layer, 3, the engineering plastics layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, Fig. 1 is a kind of magnetic composite material of the present invention, described magnetic composite material comprises magnetic material layer 1, synthetic rubber layer 2 and engineering plastics layer 3, described magnetic material layer 1 is magnetic alloy, described synthetic rubber layer 2 is acrylonitrile-butadiene rubbers, and described engineering plastics layer 3 is Merlon.
Further specify, described magnetic alloy comprises iron, cobalt, nickel and yttrium, described terne metal accounts for 38% of composite material body weight, and described aluminium oxide ceramics accounts for 28% of composite material body weight, and described asbestos account for 34% of composite material body weight.Described magnetic alloy can show three kinds of situations: (1) is antimagnetic material not by magnetic field suction; (2) faintly by the material that magnetic field attracted, be paramagnetic material; (3) material that is attracted consumingly by magnetic field claims ferrimagnet, and its magnetic sharply increases with the reinforcement of external magnetic field, and after outside magnetic field removes, still can keep magnetic.In the metal material, most of transition metal have paramagnetism.
Further specify described acrylonitrile-butadiene rubber mean molecule quantity about 700,000.Canescence is to light yellow bulk or powdery solid, and relative density 0.95～1.0 is dissolved in ethyl acetate, butyl acetate, chlorobenzene, MEK etc.Acrylonitrile-butadiene rubber has excellent oil resistance, and its oil resistivity is only second to polysulfide rubber and fluorubber, and the wearability that has and air-tightness.
Further specifying, described Merlon has good shock resistance, resisting heat distortion performance, and good weatherability, hardness height, therefore be applicable to the various parts of producing car and light truck, it mainly concentrates on the bumper etc. of illuminator, instrument board, heating plate, frost removal and polycarbonate alloy system.A kind of magnetic composite material of the present invention has characteristics such as magnetic, self lubricity are good, impact flexibility excellence.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
