Description
Technical field
The present invention relates to photovoltaic art, particularly relate to novel high-strength anticorrosive solaode frame.
Background technology
Solar energy is as a kind of inexhaustible, nexhaustible new green power, by the most attention of various circles of society.With
The progress of solar battery technology, and manufacture the reduction of material cost of solaode, photovoltaic power generation technology by
Gradually step into the maturation period.Photovoltaic product start from original specialized specific use product gradually to the marketization consumer
The direction of product is developed, and its range of application extend to every field.The frame of conventional solar components, usually four aluminum
Section bar, including two root length frames, two short frames and four angle keys compositions, by by bonded for four angles at four aluminum frames
Mode in inner chamber encapsulates solar panel.
Aluminium alloy is a most widely used class non-ferrous metal structural material in industry, Aeronautics and Astronautics, automobile, machine-building,
Boats and ships and chemical industry are widely applied, there is low melting point, corrosion resistance, coating heat-resisting, wear-resisting, easy and processability good etc.
Advantage, but, aluminium alloy seldom has steel strength and mouldability so that aluminium alloy cannot replace steel completely with alleviator
The weight of equipment, reduces energy resource consumption and pollutant emission.Although aluminium alloy its surface under natural environment can generate one layer of oxidation
Film resists corrosion, but the thickness of oxidation film about 4nm that in natural environment, aluminum alloy surface generates, and loose porous and structure is the most uneven
Even, corrode under severe operating conditions or from the hole of oxide-film, or occur from the fray of oxide-film, cause metal failure,
The requirement of current industrial development cannot be met.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide novel high-strength anticorrosive solaode frame, solve aluminium alloy not
There is the technical problem of steel strength and mouldability.
For solving above-mentioned technical problem, the technical solution used in the present invention is novel high-strength anticorrosive solaode frame, institute
State solaode frame and include Mg0.2%, Si 2.0%, Cu4.0%, Mn0.2%, Fe0.2%, Zr0.1% by weight percentage,
Er0.1%, Cr0.01%, Ni0.01%, Ti0.1%, Al surplus.
Novel high-strength anticorrosive solaode frame preparation method, described solaode frame is be made up of following steps:
(1) heating furnace used in pre-hot smelting at 300 DEG C and fine aluminium 1～2h；(2) fine aluminium after preheating is at decompression state
Lower smelting temperature be the heating furnace of 750 DEG C is completely melt after add monocrystal silicon granule, add in aluminum bronze after monocrystal silicon particles fuse
Between alloy, aluminum manganese intermediate alloy, aluminium chromium hardener, aluminum nickel intermediate alloy, ferro-aluminum intermediate alloy, aluminium zirconium hardener and
A small amount of rare earth element er, and be incubated a period of time and be completely melt to intermediate alloy, after being sufficiently stirred for, heating furnace is heated up, add aluminum
Titanium intermediate alloy is completely melt to aluminum titanium intermediate alloy, is cooled to 750 DEG C, skims, and adds pure magnesium, protects under conditions of vacuum
Temperature 30～40min；(4) tri-kinds of metal fining modifiers of Al-5Ti-B, Al-lOSr and RE are added, the weight hundred that three adds
Proportion by subtraction ratio is 8:1:3；(5) add refining agent fully to react, degasification, slagging-off,；(6) melted pouring metal melt is to
Preheated to the crucible of about 300 DEG C stands under conditions of 100MPa 2h, form ingot casting；(7) described ingot casting cuts into conjunction
Carrying out the homogenizing annealing of 12 hours after suitable size under conditions of 550 DEG C, stove is cooled to room temperature；(8) described ingot casting is warming up to
It is incubated 3 hours after 420 DEG C, carries out the hot rolling of five passages, after each passage hot rolling is complete, be incubated half an hour at 530 DEG C；(9) heat
Carrying out the cold rolling of three passages after rolling, aluminium alloy one end is relatively fixed and connects ultrasonic vibration apparatus, and the other end enters in milling train,
Excited frequency is 12kHz, aluminium alloy supersonic vibration pressurized extend, cold rolling after carry out 2 hours moving back at 240 DEG C to alloy
Fire processes, and obtains certain thickness aluminum alloy plate materials；(10) aluminum alloy plate materials is carried out halfhour solution treatment at 540 DEG C,
Then shrend；(11) aluminum alloy plate materials carries out the artificial aging of 5 hours at 180 DEG C；(12) by equal for mixed-powder C and V
The even surface being applied in aluminum alloy plate materials, uses crossing current continuous wave Cq laser instrument that aluminum alloy plate materials carries out laser treatment modified, makes
Obtain and while aluminum alloy sheet material surface forms nanoscale impression, mixed-powder C and V melted the surface being covered in aluminum alloy plate materials,
Using argon to protect in processing procedure, its laser process parameter area is: laser power 1.7kw, sweep speed 13mn/s,
