The protracted hydrophilicity and corrosion resistance of functional coating can be significantly improved when agent, significantly extend the service life of heat exchanger.
According to an embodiment of the invention, the functional coating includes：Corrosion-resistant coating, the corrosion-resistant coating are formed in the wing
On at least part outer surface of piece；Hydrophilic layer, the hydrophilic layer are arranged in the corrosion-resistant coating far from the fin
On surface；Lubricant layer, the lubricant layer are arranged on surface of the hydrophilic layer far from the fin；Wherein, the anticorrosion
Layer includes polyacrylate solidfied material, and at least one of the corrosion-resistant coating, the hydrophilic layer and described lubricant layer wrap
Include the age resister.The lubricant layer in functional coating can effectively play the effect of protection hydrophilic layer and corrosion-resistant coating as a result,
So that functional coating has more preferably anticorrosive property and hydrophily, and make functional coating containing age resister in functional coating
Preferable hydrophily or corrosion resistance, the service life of heat exchanger can be kept longer in the long-term use.
According to an embodiment of the invention, anti-aging described in the corrosion-resistant coating, the hydrophilic layer or the lubricant layer
The content of agent is 0.1-2wt%.The weatherability of functional coating is preferable as a result, and corrosion-resistant coating, lubricant layer or hydrophilic layer
Compactness is higher so that the hydrophily and corrosion resistance that functional coating can be maintained for a long time, the performance of heat exchanger
Preferably.
According to an embodiment of the invention, when containing the age resister in the corrosion-resistant coating, contain in the corrosion-resistant coating
There are at least one of 0.1-1wt% ultraviolet absorbers, 0.1-1wt% light stabilizers and 0.1-1wt% quenchers；It is described hydrophilic
When containing the age resister in layer, contain 0.1-1wt% ultraviolet absorbers, 0.1-1wt% light stabilizers in the hydrophilic layer
At least one of with 0.1-1wt% quenchers；When containing the age resister in the lubricant layer, contain in the lubricant layer
At least one of 0.1-1wt% ultraviolet absorbers, 0.1-1wt% light stabilizers and 0.1-1wt% quenchers.As a result, anti-
The lasting parent of functional coating can be significantly improved when the age resister of above-mentioned content being added in corrosion layer, lubricant layer or hydrophilic layer

Specific implementation mode
The embodiment of the present invention is described below in detail.The embodiments described below is exemplary, and is only used for explaining this hair
It is bright, and be not considered as limiting the invention.Particular technique or condition are not specified in embodiment, according to text in the art
It offers described technology or condition or is carried out according to product description.Reagents or instruments used without specified manufacturer,
For can be with conventional products that are commercially available.
The present invention is following understanding based on inventor and discovery and completes：
Currently, before air conditioner comes into operation, need to carry out the functional coating of fin surface in its heat exchanger hydrophilic
Test and neutral salt spray are tested to evaluate and test its hydrophilicity and corrosion resistance, and actual use could be put into after evaluation and test is qualified.
However, inventor is had found by many experiments, the functional coating of fin surface in actual use hydrophilic and anti-in heat exchanger
Rotten performance significantly lower than laboratory by drying and watering cycle and salt spray test as a result, and functional coating in use for some time
It fades serious, edge corrodes, and properties seriously reduce, and heat exchanger performance is made to significantly reduce.In view of the above technical problems,
Inventor conducts in-depth research, by largely accumulating and experiment is found surprisingly that, high temperature, high humidity and illumination heat exchanging
The performance of the functional coating of device is influenced than more significant, specifically, inventor by the functional coating of the heat exchanger to air conditioner into
Row ultraviolet light makes its aging, under may make that the hydrophily of functional coating and anticorrosive property are notable in a relatively short period of time
Drop, it is seen then that functional coating aging is the key factor for influencing coating and using.However the heat exchanger of air conditioner is in actual use process

Embodiment 10
Performance test：
1, treatment with ultraviolet light is not carried out：Tested heat exchanger is placed in 72h in neutral salt spray, tested change is measured after having handled
The hydrophilic angle (being labeled as hydrophilic angle 2) of the functional coating of hot device, the fading extent of overview function coating surface simultaneously measure function painting
Ratio shared by the corroded area of layer surface.
2, treatment with ultraviolet light is carried out：Tested heat exchanger is placed in burin-in process in ultraviolet light (UVB, 275~320nm of wavelength)
120h places it in 72h in neutral salt spray again later, and the hydrophilic angle for the functional coating for being tested heat exchanger is measured after having handled
The fading extent of (being labeled as hydrophilic angle 3), overview function coating surface simultaneously measures shared by the corroded area on functional coating surface
Ratio.
It should be noted that initial hydrophilic angle (being labeled as hydrophilic angle 1) refers to functional coating surface when not tested
Hydrophilic angle.
Embodiment 1-9 and the performance test results for not carrying out treatment with ultraviolet light heat exchanger in comparative example 1-4 are as shown in table 1,
The performance test results of heat exchanger are as shown in table 2 after progress treatment with ultraviolet light：
Table 1
Table 2
By the test result analysis to embodiment it can be found that addition age resister can be effectively improved work(in the coating
The weatherability of energy coating so that functional coating places it in higher salinity, humidity again after prolonged ultraviolet light
Can still be kept under environment with the comparable hydrophily of functional coating and corrosion resistance without ultraviolet light, and it is hydrophilic
Property and corrosion resistance it is preferable, and then improve functional coating performance.
By the test result analysis to comparative example it can be found that when adding age resister not in functional coating, pass through
The identical time is handled under identical salinity, damp condition again with after the ultraviolet light of embodiment 1-9 same times, is located
The corrosion resistance degradation of functional coating after reason, even less than without the corrosion-resistant of the functional coating for the treatment of with ultraviolet light
/ 10th of property；Hydrophilic angle becomes larger, or even increases to 10 times or more of initial hydrophilic angle, and hydrophily substantially reduces.
It can be seen that according to the performance test results of embodiment 8 and embodiment 9 when the content of age resister is more than 2wt%
When, since the compactness of functional coating is affected, the anticorrosive property of functional coating can be influenced, but depositing due to age resister
The rate that anticorrosive property and hydrophily decline during making functional coating in long-term use is slower, and is being used for a long time
Performance in journey be better than without it is anti-aging and functional coating anticorrosive property and hydrophily, it is seen then that in the effect of age resister
Anticorrosive property that functional coating is maintained for a long time and hydrophily, performance can be made preferable down.
To sum up, the middle addition age resister of functional coating can be with the service life of extension function coating so that function apply
Layer remains to keep higher corrosion resistance and hydrophily in a longer period of time.
