Abstract
The invention discloses a composite metal material with a low melt point. The composite metal material with the low melt point comprises an insulating material layer, a ceramic material layer and a natural fiber layer, wherein the insulating material layer is made of terne metal; the ceramic material layer is made of alumina ceramic; the natural fiber layer is made of asbestos; the weight of the terne metal accounts for 45%-51% of that of a composite metal material main body; the weight of alumina ceramic accounts for 23%-29% of that of the composite metal material main body; and the weight of the asbestos accounts for 22%-28% of that of the composite metal material main body. The composite metal material with the low melt point, provided by the invention, has the characteristics of being low in melt point, good in flowability, low in shrinkage, and the like.
Description
Technical field
The present invention relates to a kind of metal material, relate in particular to the low composite material of a kind of fusing point.
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 characteristics such as these material shortage flowabilities, shrinkage and fusing point height.
Summary of the invention
The object of the present invention is to provide a kind of fusing point to hang down composite material, it is low to have a fusing point, characteristics such as good fluidity and shrinkage are little.
Technical scheme of the present invention is: a kind of fusing point hangs down composite material, the low composite material of described fusing point comprises insulation material layer, ceramic material layer and natural fiber layer, described insulation material layer is terne metal, described ceramic material layer is aluminium oxide ceramics, described natural fiber layer is asbestos, described terne metal accounts for the 45%-51% of composite material body weight, described aluminium oxide ceramics accounts for the 23%-29% of composite material body weight, and described asbestos account for the 22%-28% of composite material body weight.
In a preferred embodiment of the present invention, described terne metal comprises lead, antimony, copper and tin.
In a preferred embodiment of the present invention, described terne metal accounts for 49% of composite material body weight, and described aluminium oxide ceramics accounts for 24% of composite material body weight, and described asbestos account for 27% of composite material body weight.
A kind of fusing point of the present invention hangs down composite material, and it is low to have a fusing point, characteristics such as good fluidity and shrinkage are little.
Description of drawings
Accompanying drawing 1 for low composite material one preferred embodiment of fusing point of the present invention main TV structure schematic diagram.
The mark of each parts is as follows in the accompanying drawing: 1, insulation material layer, 2, ceramic material layer, 3, natural fiber 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 the low composite material of a kind of fusing point of the present invention, the low composite material of described fusing point comprises insulation material layer 1, ceramic material layer 2 and natural fiber layer 3, described insulation material layer 1 is terne metal, described ceramic material layer 2 is aluminium oxide ceramics, and described natural fiber layer 3 is asbestos.
Further specify, described terne metal comprises lead, antimony, copper and tin, described terne metal accounts for 49% of composite material body weight, and described aluminium oxide ceramics accounts for 24% of composite material body weight, and described asbestos account for 27% of composite material body weight.Described terne metal contains antimony 3%～15%, copper 3%～10%, and the alloy kind that has also contains 10% lead.Antimony, intensity and the hardness of copper in order to improve alloy.Its coefficient of friction is little, and good toughness, thermal conductivity and corrosion resistance are arranged, mainly in order to make sliding bearing.
Further specify, described aluminium oxide ceramics is a kind of material based on aluminium oxide, and aluminium oxide ceramics has conductibility, mechanical strength and heat-resisting quantity preferably.It should be noted that and wash with ultrasonic wave.Aluminium oxide ceramics is a kind of broad-spectrum pottery.Because the performance that it is superior, in the application of modern society more and more widely, be satisfied with daily and needs property.
Further specifying, described asbestos have extremely fireproof, electrical insulating property and thermal insulation, are important fire prevention, insulation and insulation materials.Asbestos friction material or the goods that contain asbestos have nearly 3000 kinds, are mainly used in aspects such as machine driving, braking and insulation, fire prevention, heat insulation, anticorrosion, sound insulation, insulation, and wherein outbalance is manufacturing sectors such as automobile, chemical industry, electric equipment, building industry.A kind of fusing point of the present invention hangs down composite material, and it is low to have a fusing point, characteristics such as good fluidity and shrinkage are little.
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.
