Abstract
The invention provides an aluminum fin material capable of reliably preventing the tools from being worn, or the fume containing mineral composition from being produced and the special fume of the residual organic matter in the fin material coated with the organic resin from being produced, and guaranteeing the sufficient hydrophilicity and continuous stain resistance. In the aluminum fin material, the resin containing one or more of dibutyl hydroxyl toluene, carbazide compounds, L-ascorbic acid, L-sodium ascorbate, L-ascorbyl stearate, isoascorbic acid, sodium erythorbate, sodium sulphite andphytic acid is used as the resin layer of the substrate and coated on the surface of the aluminum plate or the aluminium alloy plate.
Description
Technical field
The present invention relates to a kind of aluminum or aluminum alloy that in the use in refrigeration system heat exchanger, uses and (be designated hereinafter simply as aluminium.) fin material processed, even a kind of utilize corrosion resistance with compare in the past long-term use also can protracted hydrophilicity and stain resistance and utilizing can suppress the resin coating layer that foul smell occurs and implemented the surface-treated fin material.
Background technology
The heat exchanger of air conditioner is designed to utilize narrow interval that the outstanding aluminum fin (fin) such as heat conductivity, processability and corrosion resistance is set compact thereby (compact) and effectively carry out heat exchange.But the package assembly of such fin is owing to the temperature on fin material surface when air-conditioner operation becomes below the dew point of air easily, so thereby dew condenses between inaccessible adjacent fin.In this case, the hydrophily on aluminium fin material surface is lower, and then dew more becomes hemispherical and then makes blocked state poorer, so that hinder heat exchange function or dew to be emitted to outside the air conditioner.
In order to eliminate this problem, on the surface of hydrophilicity-imparting treatment aluminium sheet self and then be processed into fin and when using, must promote the discharge of removing of dew, developed at present the whole bag of tricks.Wherein one group for using silica, perhaps, as the hydrophilization methods of aluminium sheet, forming inorganic take hydrophilic inorganic compounds such as alkali silicate or alumina sols as main component on the surface of aluminium sheet is the method (following patent documentation 1 and 2) of coat.
For example, following patent documentation 1 is in order to suppress flowing resistance and the noise that adhering to of condensate water increases heat exchanger, and in matrix (base) thus water soluble paint in cooperate synthetic silica to improve the method for the absorbability of condensate water.
Tool wear when in addition, patent documentation 2 is for fear of the smelly or fin machining in silica composition source and by cooperating alumina sol to solve as non-high-hydrophilic coating silica-based or non-glass system.
Illustrative these inorganic be that the hydrophily of hydrophilic tunicle of coat is outstanding, but the hardness of tunicle is high, thereby the tool wear when processing and forming is fin material is obvious, in addition, the distinctive cement flavor of silica or the dust flavor that also exist to occur to contain in the tunicle, be speculated as the problem of the foul smell that the dissipation of the material that is adsorbed on the silica or silicon dioxide microparticle causes.
Another group is that coat adheres to the tectal method of organic system resin (following patent documentation 3 and 4) for replacing these inorganic.
For example, in patent documentation 3, bring out hydration reaction and then promote Corrosion of Al for the long-time delay that prevents the lip-deep condensate water of fin material, proposed to utilize alkali metal salt, the ammonium salt of carboxymethyl cellulose (CMC), the hydrophily of N hydroxymethyl acrylamide to promote the surface treatment of tunicle.
In addition, patent documentation 4 is for same problem, forms the method for the organic system resin coating layer take polyvinyl alcohol and water-soluble nylon, water-soluble phenol etc., polyacrylic acid, polyethylene glycol etc. as main component.Unpleasant foul smell can not occur and keep hydrophily in these resin coating layer.
The processability of the hydrophilic tunicle of these organic system resin coating layer is outstanding and do not have a problem such as tool wear, in addition, the foul smell that does not also have silica to cause occurs, even but serious unlike inorganic system, but as described below, the undeniable generation that has the slight foul smell in organic system resin source.
The organic system resin coating layer is utilized the coating that application contains the constituent of resin coating layer on aluminium sheet such as glue spreader usually in the formation on the aluminium sheet, then carry out heat drying and implement.Then, the hydrophily aluminium fin material that produces becomes heat exchanger through the operation such as pressurization processing or copper pipe insertion, expander, soldering.Think in these a series of manufacturing processes, thereby added heat can cause the deteriorated generation of the part generation thermal decomposition foul smell of resin coating layer when resin coating layer forms or during heat exchanger.
Following patent documentation 5 is for the deteriorated foul smell that causes of the pyrolysate that suppresses the organic system resin coating layer, proposed except the organic system resin also and with the method for polyhydroxy benzenes phenolic compounds.Namely, the hydrophily inorganic agent of organic system and anti-microbial inoculum and use except causing and occur the toxicity, also cause the again generation of odorous substance or hydrophilic deteriorated, and in order to suppress stench, benzene mixed phenolic compounds in the water-soluble high-molecular compound that contains carboxyl etc.But, even process in this wise, in the situation of long-term use heat exchanger, because airborne polluter adheres to, hydrophily variation and then destroy stain resistance, can not prevent owing to film lower corrosion simultaneously through the time foul smell generation, so present situation is residual problem on smelly still.

Experiment numbers 1～23 and 28
Be on the corrosion-resistant resin layer that the resins such as epoxy system that become feature of the present invention consist of, form the aluminum fin material of 2 layers of structure that become equally the hydrophilic resin layer that contains the compound (A) such as carbonohydrazides compound that must feature of the present invention.
Then, as shown in table 3, these embodiment all are not equivalent to the situation of the bad characteristic of " * " symbol in all items, and more than half assessment items are that " zero " is more than the symbol.That is, can be clear and definite: they be that hydrophily, stain resistance, corrosion resistance are outstanding, can keep for a long time hydrophily and corrosion resistance simultaneously, and then the few aluminum fin material of the generation of foul smell.
Wherein, experiment numbers 10 is because the addition of compound (A) dibutyl hydroxy toluene is few, and hydrophily and stain resistance are slightly low.On the contrary, experiment numbers 14 is because the addition of same compound is many, and a small amount of early period of origination foul smell only.On the contrary, experiment numbers 19 since the addition of dibutyl hydroxy toluene how near the upper limit, so corrosion resistance deficiency a little.
Experiment numbers 24
This embodiment is the aluminum fin material that only forms the individual layer formation of the hydrophilic resin layer that contains compound (A), but owing to lack the corrosion-resistant resin layer corrosion resistance and through the time foul smell more weaker than described embodiment group, although and for individual layer formation hydrophily and stain resistance good.Thereby the individual layer that the feature of aluminum fin material of the present invention also is to have the hydrophilic resin layer that contains such compound (A) consists of.
Experiment numbers 25～27
These embodiment are the aluminum fin materials with resin formation of 2 layers of corrosion resistance hydrophilies, but different from described experiment numbers 1～23,28 embodiment, be the example that the corrosion-resistant resin layer only is made of the corrosion-resistant resin that does not have complex compounds (A).Even like this, from table 3 as can be known, these 3 kinds each characteristic that all can satisfy aluminum fin material.
The relatively above embodiment of the invention does not satisfy in the comparative example of experiment condition 29～31 of the condition that becomes feature of the present invention in the formation of resin bed, and the part of assessment item is judged as " * " symbol, is not suitable for use in the heat exchanger aluminum fin material.
Experiment numbers 29～31 (comparative example)
They are the aluminum fin material of the resin formation with 2 layers of corrosion resistance hydrophilies, and the corrosion-resistant resin layer is that epoxy common among the present invention is resin emulsion (emulsion), but do not have to cooperate the compound (A) that becomes feature of the present invention.Then, the hydrophilic resin layer on the surface of experiment numbers 29 does not contain compound (A) too, and corrosion resistance is slightly not enough, in addition, does not destroy foul odors.
The hydrophilic resin layer on experiment numbers 30 and 31 surface is combined with butylated hydroxyanisole (BHA) or the tertiary butylated hydroquinone different from compound of the present invention (A), does not still destroy foul odors.
From as can be known above, aluminum fin material of the present invention can be the individual layer multilayer, has the hydrophilic resin layer that specific compound (A) cooperates, on the other hand, in the situation of overlapping corrosion-resistant resin layer, also can by becoming specific corrosion-resistant resin, keep stably in a long term hydrophily, stain resistance and foul smell to suppress.
