Description
Technical field
The present invention relates to a kind of aluminum products, belong to technical field of alloy material.
Background technique
Aluminum products refer to based on aluminium, the addition element such as a certain amount of magnesium, silicon are added and control impurity content and
The alloy system of composition.Aluminium alloy have both high-intensitive, high rigidity and it is light-weight a little, be suitable as structural material.In addition to aluminium
Alloy addition element will affect outside performance, and the processing technology of aluminium alloy equally will cause influence, and traditional alloy uses die casting
Molding, the techniques such as machining turning, the disadvantage is that must machine since the tolerance grade of die casting is extremely difficult to technical requirements to protect
Demonstrate,prove the size of product；Although and powder metallurgical technique can with one-step shaping, to powder, mold it is more demanding.Moreover, passing
Hardness, intensity, the weatherability of the aluminium alloy of system etc. are also barely satisfactory.
If Chinese patent application file (publication number: 103667832A) for conventional alloys hardness it is low, it is not wear-resisting the disadvantages of,
Disclose a kind of aluminium alloy pipe, however the material of the patent aluminium alloy and technique be it is more conventional, in alloy property
It is relatively limited in promotion.
Summary of the invention
In view of the above problems, the present invention provides aluminium that is a kind of while having both high-intensitive and excellent corrosion resistance
Product.
To achieve the goals above, the invention adopts the following technical scheme: a kind of aluminum products, the aluminum products surface are set
There is SiC composite film, SiC composite film is to be mixed by SiC powder and binder according to mass percent 75-95% and 5-25%
It closes, then is sprayed into aluminum products surface, when half solidifies, then sprayed surface activating agent, natural coagulation are formed.
Surfactant is sprayed at carbonization while silicon carbide powder carries out surface bonding using binder by the present invention
Si powder surface layer, to form silica membrane, film can easily block light, gas etc. to invade silicon carbide structure
Erosion.
In above-mentioned aluminum products, the SiC composite film with a thickness of 5-10 μm.
In above-mentioned aluminum products, the binder is one or both of polyvinyl alcohol, polymethyl methacrylate.
The composition material and its mass percent of aluminum products in the present invention are as follows: C:0.18-0.25%, Cu:0.08-
0.15%, Mg:0.15-0.32%, Si:0.15-0.25%, Cr:0.05-0.15%, sisal cellulose crystallite: 0.10-
0.22%, furfuryl alcohol glycidol ether: 0.08-0.15%, surfactant: 0.22-0.42%, surplus Al.
Aluminum products of the present invention are made using the aluminium alloy that density is low, intensity is high, plasticity is good, can guarantee that the connecting rod exists
It keeps stablizing in whole design, structural behaviour.Contain the metallic elements such as C, Cu, Mg, Si, Cr, aluminium in aluminum products material of the present invention
Element fusing point is very high, and fusing speed is very slow, these metals are added can be made intermediate alloy, then the handle in the form of intermediate alloy with aluminium
Element is introduced into aluminum melt, avoids to increase temperature bring energy waste to accelerate fusing speed in this way, while can be with
It avoids bringing impurity into due to certain element oxides, and it can be made to realize high absorptivity and stabilization under lower smelting temperature
Property, be conducive to improve the quality of aluminium alloy cast ingot while reducing energy consumption and cost.And 0.10- is added in aluminum products of the present invention
The surfactant of 0.22% sisal cellulose crystallite, 0.08-0.15% furfuryl alcohol glycidol ether and 0.22-0.42% leads to
The synergistic effect generated between each component is crossed, the mechanical property and corrosion resistance of aluminum products are further increased.Wherein, of the invention
Containing the identical surfactant sprayed with SiC composite film surface in aluminum products material, the two can be echoed inside and outside, although
The surfactant sprayed when surface treatment falls in mixture surface layer mostly, but still have can penetrate on a small quantity directly with aluminum products surface
Contact, at this point, identical surfactant can dissolve each other completely, this just promotes the bond strength of film layer Yu aluminum products aluminium alloy, knot
It closes intensity ratio and uses the high 10-20% of other surfaces activating agent.And sisal cellulose crystallite be by sisal fiber through dilute acid hydrolysis and
It is a series of to handle a kind of obtained levelling off degree of polymerization product, the property with low polymerization degree and bigger serface, fabulous flowing
Property, as reinforcing material, cellulose crystallite also has high-modulus, low-density, heat-resist, preferable with polymer matrix compatability
The advantages that.Exactly because sisal cellulose crystallite has high-intensitive, high-modulus and certain draw ratio, with aluminium alloy in-situ polymerization
Improve its dispersibility in furfuryl alcohol glycidol ether, while the hydroxyl of sisal cellulose microporous surface and furfuryl alcohol glycidol
Esterification occurs for ether, reduces hydrophilic alcoholic extract hydroxyl group, reduces the polarity of sisal cellulose crystallite, increase composite material
Interface compatibility, when being acted on by load, the chemical bonds and physics of sisal cellulose crystallite and furfuryl alcohol glycidol ether
The double action of network, so that the intensity of composite material is enhanced.
Preferably, the viscosity of the furfuryl alcohol glycidol ether is 22-27mPa.s.Furfuryl alcohol glycidol ether is made by π-π
With sisal cellulose microporous surface is adsorbed in, sisal cellulose crystallite phenomenon easy to reunite in a polymer matrix is overcome, is made
Sisal cellulose crystallite can carry out good dispersion in epoxy matrix.In addition, as epoxy monomer, furfuryl alcohol glycidol ether
It is preferable with the binding performance of sisal cellulose crystallite, it is hindered simultaneously when initial crack propagation is by furfuryl alcohol glycidol ether
It has occurred partially deflected, is conducive to absorb a large amount of energy to failure, when the content of furfuryl alcohol glycidol ether is higher, furfuryl alcohol shrinks sweet
The visible apparent agglomeration of the crimped section of oily ether material and stress collection is also easy to produce around the aggregate of furfuryl alcohol glycidol ether
In, it enables aluminum alloy to matrix and generates defect, lead to its mechanical properties decrease.Therefore the present invention is shunk sweet using the furfuryl alcohol of said components
Oily ether.
In above-mentioned aluminum products, the surfactant in the surfactant and aluminum products material of spraying is dodecyl
One of trimethyl ammonium chloride, sodium sulfate of polyethenoxy ether of fatty alcohol, sldium lauryl sulfate are a variety of.
In above-mentioned aluminum products, the dosage of sprayed surface activating agent accounts for the 1-5% of SiC composite film gross mass.Spray
The dosage of surfactant is the 1-5% of both SiC powder and binder quality sum.
Compared with prior art, the present invention has the advantage that
1, aluminum products surface of the invention is equipped with SiC composite film, and film surface is also especially coated with surfactant, shape
At silica membrane, and then composite film is formed, improves alloy to the resistance of environment.
2, also contain surfactant in the raw material of aluminum products of the present invention, it is living with the surface of SiC composite film surface spraying
Property agent, the two can be echoed inside and outside, evolve as saturated solid solution, and assistant alloy addition element and Al agree with degree.
3, sisal cellulose crystallite, furfuryl alcohol glycidol ether and surfactant are added in aluminum products of the present invention, passes through
The synergistic effect generated between each component further increases the mechanical property and corrosion resistance of aluminum products.
