Description
Technical Field
The invention relates to a preparation method of a composite material, in particular to a preparation method of a composite material and a continuous extrusion device thereof.
Background
With the improvement of power transmission and transformation technology and the development of power transmission and transformation lines, more and more large spans need to use wires which can not only transmit large current, but also bear large tension. Aluminum alloy conductors show the advantages in this respect, and have exclusive advantages in long-distance, large-span and ultrahigh-voltage transmission. At present, the materials of the aluminum alloy wire comprise pure aluminum and aluminum-magnesium-silicon alloy, but the mechanical property and the electrical property of the pure aluminum and the aluminum-magnesium-silicon alloy are low in matching performance. Pure aluminum has good conductivity but low strength; due to the addition of alloy elements such as Mg, Si and the like in the aluminum-magnesium-silicon alloy, the strength of the material is improved, and the conductivity is reduced. In recent years, as the suspension span of overhead transmission lines becomes larger, higher requirements are made on the performance of aluminum conductor cables. Therefore, it is necessary to develop a new aluminum conductor cable with high strength and good conductivity.
Graphene is a two-dimensional nanomaterial composed of carbon atoms, and is in a single-layer sheet structure (with a thickness of only a few nanometers). Due to the unique two-dimensional honeycomb crystal structure and extremely high bond strength, graphene is the hardest nano material with the highest specific strength in the world, and the strength of the graphene reaches 130GPa, the Young modulus is about 1100GPa, and the breaking strength is about 125 GPa. More importantly, graphene is also the material with the lowest resistivity in the world (the resistivity is only about 10n Ω · m), and the conductivity reaches 200% IACS. Therefore, the graphene/aluminum composite material is prepared by utilizing the high strength and good conductivity of the graphene and compounding the graphene/aluminum composite material with pure aluminum or aluminum composite material, and is expected to be used for improving the strength and conductivity of the aluminum cable, so that the mechanical property and the electrical property of the aluminum conductor are better matched, and the urgent requirements of overhead power transmission lines on novel aluminum conductor cables with high strength and good conductivity are met.
The preparation method of the graphene aluminum wire comprises a melt casting method and a powder metallurgy method. By adopting the traditional melting casting method, due to the large density difference and the non-wetting interface, the graphene is difficult to be uniformly dispersed in the aluminum liquid, and in addition, the graphene and the aluminum liquid are likely to have high-temperature interface reaction in the material preparation process to generate Al4C3Brittle phases, deteriorating material properties. One disadvantage of using conventional powder metallurgy is the production discontinuity, the limited wire length, anda series of auxiliary operations such as separating excess pressure and filling blanks are needed between the extrusion of the rear blanks, and the production efficiency of the aluminum conductor is influenced. Therefore, in order to realize the engineering application of the graphene aluminum conductor and adapt to the large-scale production of aluminum conductor cable products, the existing process level needs to be broken through, and a batch production process which is low in cost and can realize continuous production is created.
