Electronic components will be developed towards ultra-thin and light weight, and especially in the high-frequency working environment, a large amount of heat will be increased rapidly, and effective heat dissipation capability becomes a key factor influencing the service life of the electronic components. According to incomplete statistics, about 55% of the causes of electronic product failure are due to overheating and heat related problems. Therefore, in order to ensure the reliability of operation, materials with high heat conductivity and high stability are needed to be used for quickly, timely and effectively transferring the heat accumulated by the heating element to the heat dissipation equipment so as to ensure the normal operation of the electronic equipment.
The aluminum alloy is gradually applied to the field of heat conduction by virtue of the advantages of light weight, good formability, good heat conduction and radiation performance, cost performance and the like. Pure aluminum has a thermal conductivity second to silver, copper and gold, about 5 times that of steel at room temperature, but has a severely insufficient strength. At present, typical high-thermal-conductivity aluminum alloys mainly comprise Al-Si cast aluminum alloys such as DX17, DX19 and A413, the thermal conductivity of DX17 and DX19 is as high as 155-184W/(m.K), but the yield strength is less than 120MPa, the yield strength of A413 is 145MPa, but the thermal conductivity is only 121W/(m.K).
TABLE 1 Heat-conducting Property of some typical aluminum alloys
The thin material is difficult to thread in the continuous annealing line production, and is easy to wrinkle and even break under the high-temperature and rapid-heating quenching condition, so the minimum thickness of the continuous annealing furnace production is generally 0.5mm, and the solution quenching treatment of the thin plate with the thickness less than 0.5mm cannot be carried out; and by adopting a box-type solid solution and water quenching mode, the temperature is slowly increased, the transfer time is long, the cooling is slow, and a good structure is not easy to obtain, so that the performance of the product is influenced. At present, there are few patent reports of aging strengthening type 6 series thin materials production process. The invention breaks through the limitation of equipment capability, obtains work hardening through cold rolling after solution and aging, and combines dislocation recovery and second phase precipitation in the annealing process of finished products to obtain good structure property proportion.

Detailed Description
The present invention will be further described with reference to the following examples, but the present invention is not limited to these examples.
The thermal conductivity and the electrical conductivity of the metal material follow the Vieman-Franz law (Wiedeman-Franz), and the higher the electrical conductivity of the metal, the higher the thermal conductivity.
The heat conductivity of the aluminum alloy is influenced by more factors, such as the types and contents of alloy elements, the degree of lattice distortion in the structure, defects, impurities, a second phase, the morphology, the size and the distribution of the second phase, and the like.
The invention aims to provide a preparation method of a high-heat-conductivity high-strength aluminum alloy sheet, which comprises the following components in percentage by mass: 0.40-0.80% of Si, 0.80-1.2% of Mg0.80, 1.0-1.7% of Mg/Si, 0.08-0.15% of Fe0, less than or equal to 0.02% of Cu, 0.01-0.05% of Mn0.03-0.05% of Ti, and the balance of aluminum and inevitable impurities.
Mg in aluminum alloy2Si phase as the main strengthening phase, Mg2Si in mass fraction Mg: si =1.71, Mg: si =1.0-1.7 is excessive Si type, so that a good aging effect is easily obtained, but excessive Si easily causes the material to become hard and brittle, and the strength of the bonding material is required, and Si0.40-0.80%, Mg0.80-1.2%, and Mg/Si =1.0-1.7 are preferable.
Proper Fe can refine grains, and excessive Fe forms coarse refractory AlFeMn or AlFe phases, which affect the plasticity of the product. Therefore, Fe0.08-0.15% is controlled.
Too much Cu reduces the plasticity and corrosion resistance of the alloy, and the Cu content is preferably controlled to be less than 0.04%.
Mn mainly plays a role in solid solution strengthening and grain refinement, and the Mn component is too small, so that the effect is poor; when the Mn content is too high, coarse phases are easily formed, and the moldability is lowered. Therefore, the Mn content is controlled to be 0.01-0.05%.
Ti is used as an important grain refiner in the casting process to improve the original grain structure, but excessive Ti is easy to cause TiB2The inclusions are aggregated to influence the plasticity and the surface quality of the finished product, so that the content of Ti is controlled to be 0.03-0.05%.
The preparation method of the high-heat-conductivity high-strength aluminum alloy sheet is prepared by hot rolling, cold rolling, solution quenching, aging, cold rolling and finished product annealing.
The solution treatment is a process of re-dissolving a precipitated phase and a process of re-crystallizing rolled flat and long grains. On a continuous air cushion furnace, the solid solution temperature is 500-530 ℃, the heat preservation is 10-60 s, and the water quenching or air cooling speed is more than or equal to 10 ℃/s, so that the full solid solution is ensured, and the abnormal growth of crystal grains is also avoided.
The transformation of the alpha supersaturated solid solution to beta is promoted by artificial aging at 130-200 ℃ for 5-24 h, and higher strength and good thermal conductivity are obtained by a precipitation strengthening mode.
And after aging, continuously cold rolling to the thickness of 0.5-1.0 mm, and obtaining more dislocation density and higher strength in a work hardening mode.
Annealing the finished product at the temperature of 80-180 ℃ for 1-24 h promotes dislocation density reduction, lattice distortion reduction, internal stress reduction and plasticity increase, and promotes precipitation of a second phase, so that heat conductivity is improved.
And then cleaning, straightening and slitting the finished product to obtain the finished product with a good plate type.
The following describes a specific embodiment.
