Abstract
The present invention provides a kind of production method of aluminum alloy curtain walls, and 0.3 ~ 0.5 μm of surface roughness Ra, Rz1.4 ~ 2.4 μm, same roughness Ra difference≤0.1 μm for rolling up upper any position, the aluminum alloy coiled materials of difference≤0.6 μm Rz are made first；Then by aluminium coiled material through rolling anodic oxidation production line continuous anodic oxidation, and it is directly cut to after anodic oxidation the curtain wall panel of required scale lengths.Direct cutting plate after coiled material anode of the present invention, production process surface contusion defect is few, and qualification rate is high and reduces production cost；And after control rough overshoot and internal grain, it is effectively ensured without glossiness and presentation quality after the anodic oxidation under chemical polishing processing.Make present invention production is lower to have the characteristics that high-efficient, at low cost, presentation quality is uniform and stable, has broad application prospects.
Description
Technical field
The invention belongs to the preparation fields of construction material, and in particular to a kind of production method of aluminum alloy curtain walls.
Background technique
With the rapid expansion in city, high buildings and large mansions are in a compact mass, and the exterior wall cleaning of skyscraper annoyings each object always
Industry management company: using glass outer wall, is easy pollution；Building load is significantly increased in glittering and translucent marble；Traditional plastic-aluminum is multiple
There is kindling hidden danger in plywood.So gradually begin to use in the market anticorrosion, it is durable, bear dirty, the sun that light weight and environmental protection are beautiful
Pole aoxidizes curtain wall.
In existing aluminium alloy curtain wall board fabrication method, as patent CN105177328 A discloses a kind of curtain wall aluminium
Sheet alloy manufacture craft is made after anode using die-casting process and obtains the good curtain wall aluminum alloy plate materials of durability, but piece
Material production efficiency is low, simultaneously because it is produced using die-casting process, color difference is easy to appear under low temperature anode, therefore surface sophistication is not
It is good；On the other hand, sheet material anode will also be possible to occur changing because of anode parameter between batch or tank liquor concentration, cause color difference difference,
Seriously affect the color difference consistency of appearance.Patent CN105040064A discloses a kind of preparation method of novel aluminum alloy, leads to
Cross chemical polishing processing before anode and obtain expected low surface roughness, thus guarantee anode oxide film at film uniformity, be
The high gloss of its anode oxide film is improved, aluminium increases electrophoretic process technique, but the process chemistry after anodic oxidation
Polishing and electrophoretic process time are long, and roughness is unstable, extend the production time and influence efficiency, while changing and throwing liquid and electrophoresis groove liquid
Discharge is the factor that adversely ball is protected.
Summary of the invention
The object of the present invention is to provide a kind of opposite conventional anodization Aluminum curtain wall plate high production efficiency, anodic oxidation
The production method of the more environmentally protective curtain wall aluminum alloy sheets and strips of process can inexpensive, quickly, environmentally friendlyly produce
The stable curtain wall product of anode appearance quality out.
To achieve the above object, the technical solution under the present invention is:
A kind of production method of aluminum alloy curtain walls, specific steps are as follows:
1) after semi-continuous casting, the big plate ingot for meeting curtain wall and using of acquisition, ingot casting ingredient according to the intensity that finally uses and
Appearance configuration；
2) surface roughness is obtained after necessary sawing, milling face, homogenization, hot rolling, cold rolling, heat treatment and cold rolling after
Within Ra0.3 ~ 0.5 μm, Rz1.4 ~ 2.4 μm, same roughness Ra difference≤0.1 μm for rolling up upper any position, Rz difference≤0.6 μ
M, length-width ratio≤2 of surface microscopic crystal grain, the aluminum alloy coiled materials of 900 ~ 2300mm of width；
3) above-mentioned coiled material is produced on continuous coiled material anodic oxidation production line, the preparatory alkali cleaning of aluminium, then in anode tank liquor
Electrochemical reaction occurs as the cathode being continuously arranged on the anode of electrode, with machine column, and ultimately forms fine and close anodic oxidation
Film, the curtain wall panel products of size needed for then cutting plate is made after drying；
Dirty in order to remove surface in step 3), the alkali cleaning time is 10 ~ 90s, preferably 20 ~ 50s, and in order to quickly be formed enough
The anode oxidation membrane of thickness, anode tank liquor temperature need to be controlled at 3 ~ 10 DEG C, guarantee low temperature anodic oxygen erosion consumption effect
Rate reduces, and preferably 5 ~ 8 DEG C；And control 1 ~ 2.0A/dm of current density2, it is therefore intended that the consistency for improving anode micro porous guarantees to make
With the corrosion resistance of process Anodic Oxide Film, preferably 1.2 ~ 1.3A/dm2, and cooperate the reasonable machine column speed of 10 ~ 50m/min
Production；
Remarkable advantage of the invention is:
(1) the aluminum alloy curtain walls preparation method under the present invention is compared with conventional curtain wall plate preparation method, due to surface roughness
The control of Ra value is moderate, dampens seldom, improves caused by the surface intercalated dislocation of product after substrate manufacturing process and anodic oxidation
The stability of surface quality and final qualification rate；And the directly life of cutting plate acquisition final products after being produced by continuous anodic oxidation
Production mode is greatly shortened production process, further improves overall acceptability rate, is conducive to continue to reduce production cost.
(2) pass through the length-width ratio of control Rz value and aluminum substrate internal grain, the gloss of the oxidation film after promoting product anode
Degree and uniformity make the product under the present invention under conditions of without chemical polishing, obtain with low surface roughness aluminium through short
When chemical polishing after the anode appearance after anodic oxidation again after anodic oxidation or general roughness aluminium through a long time chemical polishing
Effect is suitable, more environmentally-friendly efficient；
(3) present invention is due to using directly cutting plate after coiled material continuous anodic oxidation to obtain finished product, Opposite blade anode production efficiency
Significant increase is obtained, energy-saving and environmental protection of the present invention, presentation quality are excellent, have a vast market foreground.
