Abstract

The invention discloses a copper aluminum alloy wire, which comprises the following components in weight percent: 0.01 to 1.2wt% of Fe, 0.01 to 0.3 wt% of B, 0.01 to 0.1wt% of Si, 0.01 to 0.5wt% of Mg, 0.01 to 0.5wt% of rare earth element, 0.01 to 1wt% of modified zinc oxide, 15.00 to 16.00wt% of Cu and the balance of aluminum and inevitable impurities. The formula of the modified zinc oxide-containing wire provided by the invention has better performance than that of aluminum, aluminum alloy, copper and copper alloy, improves the electric conductivity and tensile strength of the wire, reduces the production cost continuously, and improves the preparation process continuously, thereby bringing convenience to the application of the wire material by customers in aspects of quality and demand, greatly improving the working efficiency of the finished product, and creating a higher economic value for the enterprise.

Description

A kind of albronze wire

Technical field

The present invention relates generally to a kind of albronze wire, belongs to technical field of electric wires and cables.

Background technology

Wire especially contains the wire of aluminium and aluminium alloy, cupric and copper alloy, because it has superior conductivity, corrosion resistance, lightweight and good thermal conductivity, superior intensity and fatigue proof performance, obtains the general widely application of current social.But along with the development of electronics industry causes aluminium and aluminium alloy, copper and copper alloy to be applied in many new fields, such as the connecting material of electronic unit, blaster fuse frame material etc., and the combination property of copper base conductive material had higher requirement, thereby develop high frequency, high-strength, height is led aluminum copper alloy material and is very important.

Summary of the invention

The object of the invention is exactly for a kind of albronze wire is provided.

The present invention is achieved by the following technical solutions:

A kind of albronze wire, this albronze comprises: the Cu of the rare earth element of Mg, the 0.01-0.5wt% of Si, the 0.01-0.5wt% of the Fe of 0.01-1.2wt%, the B of 0.01-0.3wt%, 0.01-0.1wt%, the modified zinc oxide of 0.01-1wt%, 15.00-16.00wt%, remaining is aluminium and inevitable impurity.

The preparation method of described modified nano zinc oxide is: in the ultrasonic absolute ethyl alcohol that is scattered in 5-8 times of its quality of nano zine oxide, obtain dispersion liquid, then the surfactant sodium phosphate trimer with its quality 4-6% adds in the above-mentioned dispersion liquid, back flow reaction is 1～2 hour under 80～90 ℃ of temperature, then filter, centrifugation filtrate obtains modified nano zinc oxide.

Described rare earth element is one or more of lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium.

Advantage of the present invention is:

A kind of prescription that contains the wire of modified zinc oxide composition provided by the invention, both had than outside the more superior performance of aluminium and aluminium alloy, copper and copper alloy, can also improve simultaneously conductance and the tensile strength of conductor material, also can constantly reduce production cost, constantly perfect to preparation technology, both made things convenient for the application of client to conductor material quality and demand, greatly improved the operating efficiency of finished product, for enterprise creates higher economic worth.

Embodiment

Embodiment 1

A kind of albronze wire, this albronze comprises: the Cu of the rare earth element of Mg, the 0.5wt% of Si, the 0.5wt% of the Fe of 1.2wt%, the B of 0.3wt%, 0.1wt%, the modified zinc oxide of 1wt%, 16.00wt%, remaining is aluminium and inevitable impurity.

The preparation method of described modified nano zinc oxide is: in the ultrasonic absolute ethyl alcohol that is scattered in 5-8 times of its quality of nano zine oxide, obtain dispersion liquid, then the surfactant sodium phosphate trimer with its quality 6% adds in the above-mentioned dispersion liquid, back flow reaction is 2 hours under 90 ℃ of temperature, then filter, centrifugation filtrate obtains modified nano zinc oxide.

Described rare earth element is lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium.

Produce the albronze wire of component content of the present invention by traditional handicraft, after testing, conductance is 61.1%IACS, and tensile strength is 290MPa, all is higher than traditional albronze wire.
