Embodiment
In this example, use Fig. 1 and Fig. 2 that the height reflection precoating aluminum alloy plate of the embodiment of the invention is described.The present invention is not limited only to these embodiment.
In this example,, make 12 kinds of precoating aluminum alloy plates (sample E1～sample E12), reach, make 8 kinds of precoating aluminum alloy plates (sample C1～sample C8) as comparative example of the present invention as embodiments of the invention.
As shown in Figure 1, this routine height reflection precoating aluminum alloy plate 1 (sample E1～sample E12) is the precoating aluminum alloy plate 1 of the precoated shet 3 of the one side that has the substrate 2 that is made up of aluminium alloy plate, be formed at this substrate 2.
When making this routine height reflection precoating aluminum alloy plate 1, at first,, prepare the 1050-H24 aluminium alloy plate of thickness 0.5mm as the substrate that constitutes by aluminium alloy plate 2.
In addition; As the base resin 42 that constitutes above-mentioned precoated shet 3, the normal reflection reduced rate before and after the application when preparation is formed with filming of thickness 10 μ m on the aluminium alloy plate of normal reflection rate more than 80% is that 5% mylar, above-mentioned normal reflection reduced rate are that 20% mylar, above-mentioned normal reflection reduced rate are that 6% polyurethane resin, above-mentioned normal reflection reduced rate are 10% acrylic resin.
Above-mentioned normal reflection reduced rate is with the above-mentioned base resin of monomer application 10 μ m on the surface of the aluminium alloy plate of normal reflection rate 84%; Measure the test of the normal reflection rate after the application, calculate with normal reflection reduced rate=100-{ (the normal reflection rate (%)/84% after the application) * 100} (%).
In addition, as the high reflecting material 41 that constitutes above-mentioned precoated shet 3, preparing average grain diameter and be 0.5 μ m, 0.1 μ m, three kinds of titanium oxide of 0.06 μ m, average grain diameter is three kinds of barium sulfate of 1 μ m, 10 μ m, 15 μ m.
Then, after with the bases degreasing agent aforesaid substrate 2 being carried out degreasing, in the chromium phosphate hydrochlorate is bathed, implement the chromium phosphate hydrochlorate and handle the formation chemical composition coating, promptly chromate film 5.The Cr content that the chromate film amount is set in the film is 20 ± 5mg/m
2Amount.
Then, respectively to sample E1～sample E12, sample C1～sample C8, on the chemical composition coating 5 of aforesaid substrate 2, use excellent coating machine to be coated in the base resin 42 shown in the table 1 coating that contains the high reflecting material 41 shown in the table 1 with the content shown in the table 1.Afterwards, in 240 ℃ stove, carry out 60 seconds sintering, make the temperature on aluminium surface reach 230 ℃ and be cured, thus, form precoated shet 3 (high reflection layer 4), obtain precoating aluminum alloy plate 1 (sample E1～sample E12, and sample C1～sample C8).
Above-mentioned precoated shet 3 is formed by one or more layers with the mode with thickness shown in the table 1.
[table 1]
Below, the precoating aluminum alloy plate 1 that obtains is carried out the evaluation of reflectivity, processability.
< reflectivity >
Reflectivity is estimated through measuring total reflectivity.Society of color technical research institute system integrating sphere spectral photometric colour measuring meter carries out in the mensuration use village of total reflectivity.The total reflectivity of the white plate of the micropowder that is fixed with barium sulfate is set at 100%, each sample is defined as total reflectivity with the measured value of 550nm wavelength.The result is shown in table 1 in the lump.
Thickness at precoated shet 3 is under the situation more than the 100 μ m, and total reflectivity is that the average evaluation more than 95% is zero, with the average evaluation of total reflectivity less than 95% be *.In addition, under the situation of the thickness less than 100 μ m of precoated shet 3, be that average evaluation more than 88% is zero with total reflectivity, the situation of total reflectivity less than 88% is set at bad, represent with * mark.
In addition, Fig. 2 representes the mechanism of high reflection layer 4.As shown in Figure 2, high reflection layer 4 contains the big above-mentioned specific high reflecting material 41 of refractive index of specified quantitative in the base resin with light transmission 42, also have specific thickness.And, invade the above-mentioned base resin 42 of light transmission of above-mentioned precoated shet 3 (high reflection layer 4), reflect at the interface of above-mentioned base resin 42 and above-mentioned high reflecting material 41, therefore, can obtain high reflectivity.
< processability >
Processability is through carrying out 90 ° of bendings and the bending of U type is estimated.
90 ° of bendings, the bending of U type are not all had the average evaluation of crackle on filming be zero, sees that with on only in the bending of U type, filming the average evaluation of crackle is △, the average evaluation of 90 ° being seen crackle when crooked on filming for *.The result is shown in table 1 in the lump.Be evaluated as zero and the situation of △ be set at qualifiedly, will be evaluated as * situation be set at defective.
In addition, the situation that the overall merit shown in the table 1 is all qualified with the evaluation of reflectivity and processability is set at qualified (being evaluated as zero), and the underproof situation of arbitrary side of reflectivity, processability is set at defective (being evaluated as *).
As shown in table 1, the sample E1～sample E12 as embodiments of the invention has shown excellent reflectivity and processability.
In addition, the thickness of the precoated shet 3 of above-mentioned sample E1～sample 12 (high reflection layer 4) is 20～140 μ m, therefore, can reduce thickness and weight.
In addition, because above-mentioned base resin 42 and high reflecting material 41 are cheap, and can easily form above-mentioned precoated shet 3, therefore, can reduce manufacturing cost.
Like this,, can reduce thickness and weight, reduce manufacturing cost, can obtain the excellent height reflection precoating aluminum alloy plate of formability and reflection characteristic according to this example.
In addition, as appreciable from table 1, as the sample C1 of comparative example, the thickness of precoated shet (high reflection layer) exceeds the upper limit of the present invention, and therefore, though reflectivity is good, processability is defective.In addition, manufacturing cost increases.
In addition, the thickness of the precoated shet of sample C2 is lower than lower limit of the present invention, and thus, reflectivity significantly reduces, and reflectivity is defective.
In addition, the average grain diameter of the high reflecting material of sample C3 is lower than lower limit of the present invention, therefore, sees through visible light easily, and reflectivity reduces, and reflectivity is defective.
In addition, the content of the high reflecting material of sample C4 is lower than lower limit of the present invention, and therefore, reflectivity reduces, and reflectivity is defective.
In addition, the content of the high reflecting material of sample C5 exceeds the upper limit of preferable range of the present invention, and therefore, high reflecting material increases from the number that comes off of filming easily, and in addition, in adding the precoated shet in man-hour, becoming is easy to generate crackle, and processability is defective.
In addition, the average grain diameter of the high reflecting material of sample C6 is greater than average grain diameter of the present invention, and therefore, above-mentioned high reflecting material increases from the number that comes off of filming easily, and in addition, in adding the precoated shet in man-hour, becoming is easy to generate crackle, and processability is defective.
In addition, the normal reflection reduced rate of the base resin of sample C7 and sample C8 exceeds the upper limit of the present invention, and therefore, resin is many to the absorption of light, thus, becomes the reason that total reflectivity reduces, and reflectivity is defective.
In addition, in this example, above-mentioned precoated shet 3 only forms in the one side of aforesaid substrate 2, still, can certainly be located at the two sides of aforesaid substrate.
In addition, in this example, high reflecting material is set at single kind, still, under the situation of the multiple high reflecting material of combination, also can obtain same effect.
