Description
The present invention relates to a kind of nano method for treating of aluminium shape surface.
Nanotechnology is an emerging technology, has obtained research and development at present in a lot of fields.But, nanotechnology is applied to the processing of aluminium shape surface, still belong to initiative.
The aluminium section bar that usual way is made can not be resisted corrosion, and is not wear-resisting, do not have discoloration, not uprising solarization, and the acclimatization ability can't guarantee durable in use.Not long for some time is spent after having carried out the aluminium alloy finishing in the house, and the aluminum alloy doors and windows that glitter will be overshadowed.
Purpose of the present invention is to provide a kind of method with the nanotechnology treatments aluminium alloy.
The present invention is by the following technical solutions:

Because the present invention has adopted the technical scheme that adds nanometer in coloring liquid and colo(u)r coating, make that aluminium shape surface treat surface opposing burn into of the present invention is wear-resisting, weather-proof, metachrosis greatly improves, and can reach durable in use.
Below in conjunction with embodiment in detail the present invention is described in detail.
The Nanosurface of aluminium section bar heat-tinting and electrophoretic painting is handled:
Add nanometer in aluminium section bar common anode heat-tinting material and the coloring liquid and in the electrophoresis liquid, its Production Flow Chart is:
Degreasing → washing → neutralization → washing → oxidation → washing → washing → painted → washing → washing (deionized water) → electrophoretic painting → washing → washing → oven dry → discharging
Wherein, the nanometer coloring liquid is mixed with and is divided into:

Nano aluminum section bar color coating surface treatment:
Also can carry out the color coating processing to aluminium shape surface add nanometer in colo(u)r coating after, its technical process is:
Charging → pre-treatment → oven dry → nanometer color coating → solidification treatment → discharging
The aluminium section bar that extruding is come out must carry out pre-treatment; can improve the adhesive property of powder like this, guarantee that powder coating and metal are bonding securely, and can form the thin protective membrane of one deck matrix metal; the protection matrix metal makes it not corroded in life-time service.
Wherein, pretreatment process commonly used can be divided into and embathe two kinds of formula and spray-types, and its technical process and treatment condition are:
Embathe the main chemical compositions of formula operation and treatment solution:
Degreasing, treatment solution mainly contains: yellow soda ash, silicate, phosphoric acid salt, activated media, treatment condition: 60 ℃, 3 minutes

Critical process in the pre-treatment is that chemical conversion is handled.
The nanometer colour color coating:
Aluminium section bar loading and unloading and transhipment should realize mechanize and automatization as far as possible, adopt the overhead type monorail conveyer, and track is in outside the spray booth, and powder deposition is on chain and the normal operation of influence when avoiding spraying.
The nanometer colour coating composition can utilize in pure polyester coating, fluorine carbon lacquer coating, polypropylene coating, epoxypaint, acroleic acid polyurethane coating and other dusty spray, and the nanometer that adds 2-10% respectively is that main raw material is formed.Use pure alkyd resin to be example with color coating, the relative content of particulate size and different viscosity powder directly influences the quality of paint film.In order to obtain should not contain the particle of granularity in the high paint film powder of quality greater than 90 μ m.With pure alkyd resin powder coating is example, granularity and relative percentage composition such as following table:
The granularity of powder (μ m) content
＞90 0.0
＞1--90 4.0
63--71 12.0
45--63 44.0
37--45 21.0
＜37 19.0
Add up to 100
The pure alkyd resin powder nanometer of the pure alkyd resin color coating of nanometer powder component list nanometer proportioning 90--98 part 2--10 part Ti0.3, Co0.2, Ni0.2, SiO
21.0,
Additive 0.5 abundant mechanical stirring is mixed
More than be that nanometer color coating powder reaches the best proportioning of enhanced to aluminium shape surface quality each side leading indicator.
The chromatic spray painting of the pure alkyd resin coating of nanometer, fluorine carbon coating resins coating powder, acrylic polyurethane coating spraying and various dusty spraies:
The nanometer colour powder coating is to realize by the static gun in the jet chamber; its high-voltage power supply is the electrostatic generator of a 400-100KV; by a pressure regulation range is that 0.1-0.8 atmospheric system carries powder to spray gun; static is attracted to the powder of static electrification and is coated with on the section bar; one powder particle is looped around workpiece surface and adsorbs thereon; form one deck uniform coating, strength of current generally is advisable with 1 milliampere.
In the production process, powder resistance must be moderate, generally 10
12--10
18In Ω/cm scope, charged powder particles is adhered on workpiece, the powder too high in resistance, then coating is with super thick.The spray pattern of dust gun can carry out step-less adjustment.Requirement according to the working-surface profile, the diameter that dusts of spray gun can be at 100mm (30 ° of jet angles)--changes between the 400mm (180 ° of jet angles), to recess and hollow position, should adopt little spray pattern, flat pieces and body etc. is then adopted big spray pattern.
The consumption of powder and color coating are coated with the thickness of paint film and the ability of recovery system is closely related.For example: when thickness was 40 μ m, the powder consumption of the pure alkyd resin powder of heat setting type nanometer will lack 61.5% than other coating (not adding nanometer).
The pure alkyd resin powder of nanometer and other: fluorine carbon coating resins coating powder, polypropylerie paint powder, epoxypaint, polypropylene coating are compared, and the powder consumption is all low.See table:
Hybrid poly-third epoxy resin powder of the pure polyester fluorine of nanometer carbon lacquer powder polypropylene spraying
Toner cold coating alkene powder spraying end coating

Solidification treatment:
Solidification treatment is a very important operation, and powder curing is dealt with improperly, will produce serious consequence, and there will be two kinds of situations for resulting paint film.
A. solidification treatment is insufficient, causes coating surface to be unable to bear and impacts and corrosion, even lack sticking power.
B. excessive solidification treatment then causes glossy loss, and particularly light color also can change color, influences attractive in appearancely, even can not use.
Aluminium section bar after handling through the nanometer method can the anti-efflorescence of antidusting, resists sunlight exposure and ultraviolet detrimentally affect, can also resist industrial acids, alkali, salt and sanitising agent fully and nondiscoloration, and does not come off or corrode.Simultaneously can improve aluminium shape surface hardness, free from environmental pollution, energy-conservation, durable in use.Can be widely used in the various chambers such as modernized building, kitchen, dining room, bathroom of high standard buildings, and various fields such as hospital, navigation, have extensive market prospects, foretold " Chaoyang product " into Chinese finishing material.
