Description
Technical field
The present invention relates to a kind of have the aluminum or aluminum alloy material of tunicle and the radiator fin for heat exchanger that uses this material, radiator fin for heat exchanger and material thereof that the hydrophilic persistence when particularly relating to pollutent and adhering to is good, be applicable to room conditioning (Room air conditioning) and encapsulation air-conditioning (Package air conditioning) etc.
Background technology
In the radiator fin for heat exchanger of room conditioning and encapsulation air-conditioning etc., people expect the material of heat conductivity and excellent processability always especially.So generally all use aluminum or aluminum alloy (below be commonly referred to as aluminium), be to improve heat dispersion, developed the radiator element aluminium that improves erosion resistance and wetting ability etc.
But, when in apartment office building etc., using air-conditioning recently, produce the problem of the wetting ability difference that wetting ability can not long term maintenance.Through inventor's etc. investigation as seen, on the surface of the most surperficial hydrophilic coating film of radiator element, for example the plastics of plasticizer, palmitinic acid, stearic acid or the paraffin class etc. by adhering to dimixo-octyl phthalate (DOP) etc. with lubricator wait and also are difficult to obtain the wetting ability that continues.
In apartment office building etc., the closure height in house, while many uses in wall, floor etc. contain the new building materials of all contaminations matter etc., thus, under the environment that has all contaminations matter, use the situation of air-conditioning just to become many, the reason of the hydrophilic persistence difference of thinking that Here it is.In contrast, the inventor etc. even adhere to the radiator element of the aluminium system that wetting ability also can continue for a long time under the state of pollution substance in fin surface for exploitation, and carry out research with keen determination, have proposed to open invention disclosed in the 2001-201289 communique the spy.Promptly, as hydrophilic coating film, the mixture of the polyacrylic water soluble resin that contains hydroxyl by use adding more than one, then at the tunicle that carries out the firm cementability of having of burn-back more than 200 ℃, the outflow of the water soluble resin of hydroxyl can be suppressed to contain thus, thereby secular wetting ability can be kept.
But, when making the spy open that disclosed aluminium is applicable to the radiator element of air-conditioning etc. in the 2001-201289 communique, under common atmosphere of pollutants featuring, wetting ability can be kept certain hour, but under the specific room temperature environment (for example when spraying constantly makes the pollution substance that wetting ability worsens (environment of industrial use tackiness agent etc.) or as indoorly be closed, pollution substance is constantly in the situation of indoor delay, under the environment that the concentration of pollution substance constantly uprises in the room air), thus can think that easy reduction of wetting ability of fin surface causes wetting ability insufficient.
Summary of the invention
The present invention finishes in view of described problem, even its purpose is to provide under the specific indoor environment that a kind of pollutant concentration in room air constantly increases, wetting ability can long term maintenance, and the also good heat exchanger fin of punching formation property is with aluminum or aluminum alloy material and radiator fin for heat exchanger.
Aluminum or aluminum alloy material with tunicle of the present invention, by the aluminum or aluminum alloy substrate, and to form thickness on described substrate be that the hydrophilic coating film of 0.1～10 μ m is formed, described hydrophilic coating film contains the water soluble resin of hydroxyl and a kind of composition of selection at least from phosphoric acid and phosphoric acid salt are formed by a kind of, the intramolecularly selected at least from polyacrylic acid and polyacrylate are formed.At this, with respect to from described polyacrylic acid and polyacrylate composition, selecting 100 a kind of weight parts at least, the water soluble resin that described intramolecularly contains hydroxyl is 1～200 weight part, and a kind of of selection is 1～20 weight part at least from described phosphoric acid and phosphoric acid salt composition.
In addition, the aluminum or aluminum alloy material with tunicle of the present invention is that the water soluble resin tunicle of 0.1～10 μ m is formed by form thickness on described hydrophilic coating film.At this, described water soluble resin tunicle, its intramolecularly contains hydroxyl.
Radiator fin for heat exchanger of the present invention is made by forming described aluminum or aluminum alloy material.
If according to the present invention, even can obtain under the atmosphere of pollution substance, also can keep hydrophilic for a long time, while stampability aluminum or aluminum alloy material and radiator fin for heat exchanger good, that have tunicle.
Embodiment
Below the present invention is described in detail.Heat exchanger fin aluminium of the present invention has aluminum or aluminum alloy substrate (aluminium base), is that the hydrophilic coating film of 0.1～10 μ m, the thickness that forms on this hydrophilic coating film are the water soluble resin tunicle of 0.1～10 μ m at the thickness that forms on this substrate.
Aluminium base
At first, prepare to be adjusted to aluminium (aluminum or aluminum alloy) substrate of required composition and thickness of slab, with its degreasing, then for improve erosion resistance and and be formed at cementability between the tunicle of substrate surface, on the whole surface of aluminium base, form the erosion resistance tunicle.In addition, as the erosion resistance tunicle, general for example can suitably use Plessy's green hydrochlorate tunicle, chromic acid chromium hydrochlorate tunicle, add containing the chromium tunicle or considering environmental problem recently and the coating-type zirconium class tunicle that does not contain chromium fully, response type zirconium class tunicle, coating-type titanium class tunicle or the response type titanium class tunicle that use of coating-type chromic salt tunicle behind the resin etc.At this moment, as the tunicle amount, in the preferred 1～60mg/m of inorganic metal
2The tunicle amount is lower than 1mg/m
2The time, can not obtain very good effect aspect erosion resistance and the cementability, in addition, the tunicle amount is if be higher than 60mg/m
2The time, when impact briquetting etc., the erosion resistance tunicle self is easy to generate slight crack and can not obtains desired effects.As the tunicle amount in inorganic metal, preferred 5～40mg/m
2In addition, under need not the environment of erosion resistance tunicle, or outside guaranteeing cementability, can implement end liner and handle the time, just need not described erosion resistance tunicle.
Hydrophilic coating film
After implementing described end liner processing, in its surface, form hydrophilic coating film for making it give wetting ability.Hydrophilic coating film of the present invention, with respect to from polyacrylic acid and polyacrylate composition, selecting 100 a kind of weight parts at least, contain a kind of 1～20 weight part that intramolecularly contains hydroxyl ground water soluble resin 1～200 weight part, selects at least from phosphoric acid and monophosphate monophosphate salt compounds composition.The interpolation reason of each component and composition qualification be the reasons are as follows described.
Polyacrylic acid or polyacrylate
As polyacrylate (acrylic acid or the like), for example can use polyacrylic sodium salt, sylvite or ammonium salt etc.These acrylic acid or the like, 1 pollution substance is difficult to set, and 2 can give connecting airtight property and water tolerance to hydrophilic coating film as blending resin.In addition, 3 cause dehydrating condensation esterification between the carboxyl of the hydroxyl of the water soluble resin that contains hydroxyl and acrylic acid or the like by part simultaneously, thereby can form firmer hydrophilic coating film.And 4 can prevent to contain the outflow of dripping and causing of the water soluble resin of hydroxyl owing to having the intramolecularly of giving the wetting ability effect in tunicle, thereby can play the effect that wetting ability can long term maintenance.
Intramolecularly contains the water soluble resin of hydroxyl
In addition, contain the water soluble resin of hydroxyl as intramolecularly, for example carboxymethyl cellulose, polyvinyl alcohol or polyoxyethylene glycol etc. are more suitable.
In addition, with respect to by more than one composition of forming 100 weight parts of from polyacrylic acid or polyacrylate are formed, selecting at least, will to be limited to the reasons are as follows of 1～200 weight part described by being selected from the water soluble resin that intramolecularly contains hydroxyl more than one compositions of forming.That is, when being lower than 1 weight part, because it is few to give the hydrophilic hydroxyl of tunicle, so can not obtain sufficient wetting ability.In addition, if when being higher than 200 weight parts, since very few with respect to the amount of the acrylic acid or the like of water soluble resin with hydroxyl, cause that flowing out composition in the tunicle increases so drip, thereby cause wetting ability to reduce.So,, also can keep wetting ability even under the state that pollution substance adheres to.So be necessary to be set in described scope.50～150 weight parts more preferably.
Phosphoric acid and phosphate compounds
As phosphate compounds (phosphoric acid class), for example can suitably use tripolyphosphate and sodium phosphate etc.Contain these phosphoric acid classes in the hydrophilic coating film by making, the carboxyl of 1 acrylic acid or the like and the hydroxyl with water soluble resin of hydroxyl are configured in the surface that forms tunicle, and ionized molecule on the tunicle surface (ionized atmosphere) increases.That is, on the tunicle surface, phosphate ion and have ionization after the acrylic acid or the like of carboxyl increase.2 is common, the polymkeric substance of acrylic acid or the like salt etc., formation has the ionic set tissue that is called as the zone, and these zones further form the bigger ionic set tissue that has by combining with phosphate ion, thereby the ionic atmosphere that forms the tunicle surface is increased.And then 3 according to described 1 and 2 effect, by increasing the ionic atmosphere that forms the tunicle surface significantly, can increase substantially the solid water on tunicle surface, and it is easier to be wetting that the tunicle surface becomes.Can increase substantially the pollution substance that is attached to the tunicle surface thus with the effect of dripping and discharging, thereby wetting ability also can be able to long-term maintenance.
In addition, be necessary and be adjusted in 1～20 weight part by more than one compositions of forming of from phosphoric acid and phosphate compounds are formed, selecting at least.At this moment, if be lower than 1 weight part, the effect of the ionic atmosphere on increase hydrophilic coating film surface is just insufficient, and the hydrophilic effect that improves thus under the pollutent attachment state is just insufficient.In addition, if when being higher than 20 weight parts, the hydrophilic coating film of formation and the connecting airtight property decline between the aluminium sheet, punching formation property and erosion resistance descend.So, just be necessary to be adjusted to 1～20 weight part by more than one compositions of forming of from phosphoric acid and phosphate compounds are formed, selecting at least.5～15 weight parts more preferably.
In addition, in the present invention, the thickness that will have the hydrophilic coating film of described composition is made as 0.1～10 μ m.If hydrophilic coating film thickness just can not obtain sufficient wetting ability when being lower than 0.1 μ m.In addition, if when being higher than 10 μ m, because the tunicle internal stress increases, the cementability of tunicle reduces, thereby will produce when punch process by membrane portions or whole situation about peeling off by film thickness.So, also can keep wetting ability for a long time in order to make existing under the atmosphere of pollutent, with regard to being necessary the thickness of hydrophilic coating film is made as 0.1～10 μ m.0.4～2 μ m more preferably.
The burn-back temperature of hydrophilic coating film is preferably more than 200 ℃.When the burn-back temperature of hydrophilic coating film was lower than 200 ℃, hydrophilic coating film dissolving was easily separated out, and the fragility that becomes, and cementability reduces.Hydrophilic persistence, erosion resistance and punching formation property reduce when adhering to pollutent thus.
The water soluble resin tunicle
In the present invention, after formation has described hydrophilic tunicle, on its surface, 1 for making the most surperficial oilness, the raising punching formation property given of tunicle, in addition, the acrylic acid or the like of hydrophilic coating film composition and the bonding masking material improperly of metal die when 2 conducts are used to prevent impact briquetting, the thickness that the formation intramolecularly contains hydroxyl is the water soluble resin tunicle of 0.1～10 μ m.Contain the water soluble resin of hydroxyl at this moment as intramolecularly, for example can use carboxymethyl cellulose, polyvinyl alcohol, polyoxyethylene glycol etc.
In addition, in the present invention, the thickness of water soluble resin tunicle is made as 0.1～10 μ m.When film thickness is lower than 0.1 μ m, when impact briquetting, enough lubricant effects can not be obtained, in addition, masking effect can not be obtained.Thus, when impact briquetting, will produce the peeling off of hydrophilic coating film (burn-back of colored inner face) or owing to radiator element with aluminium and punching press with the bonding processing bad phenomenon that causes between the metal die.
When the thickness of water soluble resin tunicle is higher than 10 μ m,, thereby cause tunicle to be peeled off easily owing to the increase of tunicle internal stress causes connecting airtight property decline with lower floor's hydrophilic coating film.Thus, when impact briquetting, be created in bad phenomenon such as adhering to of the resin coating peeled off in the metal die, thereby cause yield rate to reduce.So, be necessary its thickness is adjusted to 0.1～10 μ m for the water soluble resin tunicle.0.2～1 μ m more preferably.
In addition, the water soluble resin tunicle, dripping when transporting the initial stage owing to the cleaning after the impact briquetting or freezer causes wash, when using in air-conditioning etc., hydrophilic coating film is used for the most surperficial of radiator element, thereby guarantees wetting ability.
Embodiment
Below compare the effect that the embodiment of the invention is described with within the scope of the present invention comparative example not.As substrate, use the aluminium sheet after thickness of slab is handled as the H24 of the JIS A1200 of 0.10mm, as pre-treatment, utilize surf cleaner-360 (Nippon Paint Co., Ltd's system) to implement alkali degreasing.
And then, by erosion resistance tunicle, hydrophilic coating film and water soluble resin tunicle shown in following table 1～table 5 are made up, under condition shown in following table 6 and the table 7, on the surface of aluminium base, form tunicle successively, make the radiator element aluminium.But table 1 is the kind and the adhesion amount of expression erosion resistance tunicle, and table 2～table 4 is kind and composition amounts of expression hydrophilic coating film, the kind and the composition amount of table 5 expression water soluble resin tunicle.
But the erosion resistance tunicle is handled (chemical surface control) or roller painting formation by spraying.Hydrophilic coating film forms by common roller painting, and the burn-back time is 15 seconds.The water soluble resin tunicle, by roller painting application coating material, making the thickness after the heating is certain thickness, then by forming for 15 seconds 150 ℃ of following burn-backs.
For the radiator element aluminium of making under the filming condition according to table 6 and table 7, estimate its characteristic under the following conditions.
(wetting ability)
Suppose that the freezer by heat pump type air conditioner transports to greenhouse, for described for the examination material, after exposing 8 hours at flowing water 80 ℃ down dry 16 hours as a circulation, 5 round-robin cyclic wetting and drying test of repetitiousness enforcement.Afterwards, the water droplet of the 1 μ l that drips on the surface of the radiator element of making under each condition with aluminium is estimated wetting ability by the contact angle of measuring water droplet with goniometer.
In addition, the contact angle of general using water droplet is estimated wetting ability, and the expression wetting ability that contact angle is little is good usually.
(hydrophilic persistence)
Remain under the environment that combination following flowing water and pollutent expose for the examination material described, expose 8 hours after stains with flowing water and expose 100 ℃ and be one in following 16 hours and pollute circulation, implements 5 such pollutions and circulate.Afterwards, with described identical, the hydrophilic persistence when estimating pollutent and adhere to by the contact angle of measuring water droplet.
The contact angle of water droplet hour, wetting ability is good, even under the state that pollutent adheres to, can think that also wetting ability can keep for a long time.
In addition, as pollution substance, paraffin and the stearic acid floating, that seriously cause wetting ability to reduce owing to be attached to the fin material surface in the indoor environment middle reaches easily that make an addition to various resins have been used.In addition, the exposure under pollution substance atmosphere is to put into the moisture eliminator that volume is 6L simultaneously with each pollution substance 1g with for the examination material, by ℃ implementing at thermostatic bath internal heating to 100.
(foul smell characteristic)
The foul smell characteristic, to in flowing water, flood 24 hours for the examination material, after composition is separated out in the dissolving of removing the water soluble resin tunicle (dewfall of setting when transporting by the air-conditioning freezer makes the stripping of tunicle stripping composition), be dried, no foreign odor is made as ◎, being made as of strong foreign odor arranged *, between them, be made as zero and △, be divided into the metewand of four levels, feeling evaluation by 5 discussion participators is estimated, with its average achievement as evaluation result.
(erosion resistance)
By salt spray testing (JIS Z2371), estimate the corrosion condition on the fin material surface of spraying after 200 hours continuously.This erosion resistance also with will not have corrosion be made as ◎, all being made as of heavy corrosions *, between them be made as zero and four judgement criterias of △ estimate.
(punching formation property)
Under the condition of molding shown in the following table 8, use the radiator element punching press with metal die (the system DRAWLESS of Hidaka Seiki Kabushiki Kaisha shaped metal mould), in for the examination material, implement punch process, be shaped to radiator element.In addition, impact briquetting speed unit spm is the abbreviation of Stroke Per Minute, is meant the quantity that can process in 1 minute.In addition, evaluation will be estimated with the metewand of following four levels after impact briquetting 10000 times.
＜metewand 〉
Colored inner face burn-back situation: (no burn-back) ◎-zero-△-* (producing peeling off of whole tunicle); Colored shapes: (normally) ◎-zero-△-* (generation is buckled, colored slight crack, the colored partition); Foreign matter adheres to situation in pinch roll and the metal die: (no foreign matter adheres to) ◎-zero-△-* (a large amount of foreign matters adhere to).
Evaluation result according to described various metewands is summarised in following table 9 and the table 10.
As shown in table 9, embodiment 1～18th, example within the scope of the present invention, and the contact angle of the water droplet when pollutent adheres to and comparative example 1～13 are more less, and the hydrophilic persistence when pollutent adheres to is obviously good.In addition, wetting ability, foul smell characteristic, erosion resistance and punching formation property are all good among the embodiment 1～18.
Comparative example 1, because very few with respect to the amount of the acrylic acid or the like of the water soluble resin that contains hydroxyl, so the outflow composition of hydrophilic coating film increases, the hydrophilic persistence when wetting ability and pollution substance adhere to reduces.And then because tunicle becomes fragile, the tunicle of colored inner face produces bad phenomenon such as burn-back in the punch process when impact briquetting.
Comparative example 2 is equivalent to the spy and opens disclosed technology 2001-201289 number, owing to do not contain phosphoric acid and phosphoric acid salt compound in the hydrophilic coating film, that the water droplet contact angle when pollutent adheres to is compared with present embodiment is very big.Thus, open in 2001-2011289 number disclosed technology being equivalent to the spy, the hydrophilic persistence when adhering to about pollutent can be thought to obtain effect of sufficient.
Comparative example 3 because the phosphorus acid content in the hydrophilic coating film is very few, therefore can not obtain effect of sufficient in the hydrophilic persistence when pollutent adheres to.
Comparative example 4, because the phosphorus acid content in the hydrophilic coating film is too much, so the connecting airtight property decline of tunicle and produce that erosion resistance reduces and the burn-back of the colored inner face during impact briquetting.
Therefore comparative example 5 owing to do not contain vinylformic acid in the hydrophilic coating film, can not obtain effect of sufficient in the hydrophilic persistence when pollutent adheres to, and produces that erosion resistance reduces and the burn-back of the colored inner face during impact briquetting.
Comparative example 6 is the hydrophilic coating film of water glass class, and wetting ability, erosion resistance and excellent punching formation property still, in the hydrophilic persistence and foul smell characteristic when pollutent adheres to, are compared the performance extreme difference with embodiment.
Comparative example 7, because the thickness of hydrophilic coating film is too small, so the wetting ability persistence when wetting ability and pollutent adhere to is relatively poor, and erosion resistance also reduces.
Comparative example 8 because the thickness of hydrophilic coating film is excessive, so tunicle is peeled off easily, produces the burn-back of colored inner face during impact briquetting, in addition, produce the attachment issue in pinch roll and metal die.
Comparative example 9 because the burn-back temperature of hydrophilic coating film is low excessively, is separated out so hydrophilic coating film dissolves easily, and is become fragile, and cementability reduces.Hydrophilic persistence when thus, pollutent adheres to, erosion resistance and punching formation property reduce.
Comparative example 10 because the thickness of water soluble resin tunicle is too small, therefore produces the burn-back of colored inner face, because the bonding chromatic seat that causes in metal die is bent etc., and punching formation property reduces.
Comparative example 11 because the thickness of water soluble resin tunicle is excessive, therefore produces the bad phenomenon that foreign matter adheres in pinch roll and metal die.
Comparative example 12 because the water soluble resin tunicle is not set, in impact briquetting, produces bad phenomenon.
Comparative example 13 because the erosion resistance tunicle is not set, produces the problem of erosion resistance and punching formation property reduction.
