Japanese Unexamined Patent Publication No. 7-234181

By the way, in such a weather resistance tester, it is generally required to perform a weather resistance test that more closely simulates the actual environment.

Therefore, it is desirable to provide a weather resistance tester capable of performing a weather resistance test that more closely simulates the actual environment.

The weather resistance tester according to the embodiment of the present invention is separated by splitting the light from the light source unit that emits light, the sample storage box that stores the sample, and the light source unit for each wavelength region. It is equipped with a spectroscope that irradiates the irradiated surface of the sample with light. The sample storage box has a liquid storage unit for storing a predetermined liquid together with the sample. Further, a liquid immersion test conducted in a state where the sample is immersed in the liquid in the liquid storage part and a state in which the light dispersed by the spectroscope is applied to the irradiated surface of the sample, and from the inside of the liquid storage part. At least two wet tests, which are performed by exposing the sample to wet conditions in a state where the liquid is discharged and the light dispersed by the spectroscope is not irradiated to the irradiated surface of the sample. Cycle tests are performed by combining the tests so as to include them.

In the weather resistance tester according to the embodiment of the present invention, a liquid storage unit for storing a predetermined liquid together with the sample is provided in the sample storage box. As a result, in a weather resistance test (spectral aging test) in which the irradiated surface of the sample is irradiated with the dispersed light, in addition to the influence of the light, the liquid in the liquid storage portion is used (for example, the sample is liquid). By immersing it in (by immersing it in), the effect of wetting can also be evaluated. Further, by executing the cycle test by combining the above two tests under each of the above conditions so as to include the above two tests, the cycle test in which various tests are combined can be executed, so that the actual environment is further simulated. It is possible to perform a weather resistance test. Further, in such a cycle test, the influence of the presence or absence of light irradiation can be further added, so that the weather resistance test simulating the actual environment can be further performed.

In the weather resistance tester according to the embodiment of the present invention, a liquid storage unit for storing the liquid and a liquid supply mechanism for supplying the liquid from the inside of the liquid storage unit to the inside of the liquid storage unit may be further provided. In this case, the liquid is automatically supplied into the liquid storage unit, which improves convenience.

In this case, a liquid recovery mechanism for collecting the liquid from the inside of the liquid storage unit to the inside of the liquid storage unit and a heater for controlling the temperature of the liquid stored in the liquid storage unit are further provided, and a liquid supply mechanism and a liquid are further provided. The recovery mechanism may be configured to allow the liquid to circulate between the liquid storage and the liquid storage. In this case, the temperature of the liquid circulating between the liquid storage unit and the liquid storage unit is controlled, so that a highly accurate spectroscopic aging test can be realized.

Further, a liquid injection mechanism may be further provided which injects the liquid supplied by the liquid supply mechanism so as to flow from above the sample toward the irradiated surface side in the liquid storage portion. In this case, for example, as compared with the case where the liquid is supplied from the lateral direction (horizontal direction) of the sample in the liquid container, the temperature rise of the liquid due to the radiant heat of light varies (the temperature rise in the horizontal direction varies). However, it is suppressed. As a result, a highly accurate spectroscopic aging test is realized.

In the weather resistance tester according to the embodiment of the present invention, a gas supply mechanism for supplying a predetermined gas whose temperature and humidity are adjusted to the inside of the liquid storage unit may be further provided. In this case, in addition to the liquid immersion test, other tests (for example, drying test, wetting test, etc.) can be performed in the liquid storage section (sample storage box), so that the actual environment can be further simulated. It is possible to carry out the weather resistance test.

Further, it further includes a spray test performed in a state where the liquid is sprayed onto the sample in the liquid storage portion and the light dispersed by the spectroscope is not irradiated on the irradiated surface of the sample. The cycle test may be executed by combining with.

Further, the cycle test may be executed by further including and combining a drying test performed by exposing the sample to a drying condition in a state where the liquid is discharged from the liquid storage unit.

Here, examples of the liquid include water, a corrosive solution, and the like. When a corrosive solution is used as the liquid, the deterioration of the sample can be further accelerated, so that a more efficient weather resistance test (spectral aging test) can be performed. When the liquid is a corrosive solution, the sample in the liquid container is immersed in pure water after the liquid immersion test is performed with the sample immersed in the corrosive solution. The cleaning step may be carried out. In this case, crystals are prevented from being formed on the surface of the sample due to the corrosive solution, and as a result, a highly accurate spectroscopic aging test is realized.

In the weather resistance tester according to the embodiment of the present invention, when the liquid immersion test is performed with the sample immersed in the liquid in the liquid storage portion, the sample is immersed in the liquid and the liquid. Both may be provided with a non-immersed area in. In this case, the influence of the presence or absence of wetting can be evaluated by one test using one sample, so that the convenience is improved.

Here, the liquid accommodating portion is provided on the side surface of the sample excluding the irradiated surface side, the bottom surface provided on the lower side of the sample, and the testing machine main body and the liquid accommodating portion located on the irradiated surface side of the sample. It may have a sealing member for sealing between the sample and a lid provided on the upper side of the sample. In this case, the sample storage box can be directly applied (attached and used) to the existing weather resistance tester (spectral aging tester), which improves convenience. In addition, since the side surface of the liquid storage portion is not provided on the irradiated surface side of the sample, a decrease in the amount of light incident on the liquid storage portion is prevented, and a more efficient weather resistance test (spectral aging test) can be performed. It becomes possible to do.

Alternatively, the liquid storage portion may have a side surface provided including the irradiated surface side of the sample, a bottom surface provided on the lower side of the sample, and a lid provided on the upper side of the sample. .. Even in this case, the sample storage box can be applied to the existing weather resistance tester (spectral aging tester) as it is, so that the convenience is improved. In addition, since the side surface of the liquid storage portion is also provided on the irradiated surface side of the sample, a sealing member or the like is not required (no need to consider liquid leakage), so that wetting evaluation with a simple structure is required. Becomes feasible.

In the weather resistance tester according to the embodiment of the present invention, in the tester main body, the irradiated surface side of the sample in the liquid storage portion may be composed of a light transmitting member that transmits light dispersed by a spectroscope. Good. In this case, the liquid does not enter the weather resistance tester, and the decrease in the amount of light incident on the liquid storage part (loss of light amount) is suppressed, so that a more efficient weather resistance test (spectral aging test) is performed. Can be done.

Further, a sample mounting jig for mounting a sample may be further provided in the liquid storage portion, and the sample mounting jig may have an irradiation wavelength scale indicating a guideline for the irradiation wavelength of the light dispersed by the spectroscope. .. In this case, when the sample is mounted in the liquid storage portion, the position of the wavelength of the light applied to the irradiated surface can be easily adjusted, which improves convenience.

According to the weathering resistance tester according to the embodiment of the present invention, the sample storage box is provided with a liquid storage portion for storing a predetermined liquid together with the sample. In addition to the effect, the effect of wetting can be evaluated. Therefore, it is possible to perform a weather resistance test that more closely simulates the actual environment.

It is supplied to the inside (inside the liquid storage unit 151 which will be described later). In other words, the gas (wet air Aw or dry air Ad) whose temperature and humidity are adjusted in this way is supplied from the temperature control humidity control unit 2 into the sample storage box 15 in the irradiation unit 1.

[Detailed configuration of sample storage box 15]
Subsequently, a detailed configuration example of the sample storage box 15 described above will be described with reference to FIGS. 3 in addition to FIGS. 1 and 2.

FIG. 3 schematically shows a detailed configuration example of the sample storage box 15 and the like in a cross-sectional view (YZ cross-sectional configuration diagram). As shown in FIG. 3, the sample storage box 15 has a liquid storage portion 151 and a packing 152.

Specifically, the liquid storage unit 151 includes a side surface including the side surface S1 provided on the side opposite to the irradiated surface Si of the sample 9 (back side of the sample 9) and a lower side (on the Z axis) of the sample 9. It has a bottom surface B provided on the negative side) and a lid (cover) C provided on the upper side (positive side on the Z axis) of the sample 9. Further, as shown in FIG. 3, the side surface of the liquid storage portion 151 is provided except for the Si side of the irradiated surface of the sample 9. That is, the side surface of the liquid accommodating portion 151 is not provided on the Si side of the irradiated surface of the sample 9, and the light transmitting member 150 is arranged via the liquid W. Although the lid C has a reference numeral in FIG. 3 and FIGS. 7 to 9 described later, it is not shown for convenience.

Further, a packing (not shown) is also provided along the Z axis on the side surface (side surface parallel to the paper surface) of the liquid storage portion 151, and also in the modified examples 1 and 2 (FIGS. 7 and 8) described later. It is similar. Such packing 152 and the packing on the side surface are the testing machine main body (in this example, the light transmitting member 150 in the irradiation unit 1 main body) and the liquid storage portion 151 (in this example) located on the irradiated surface Si side of the sample 9, respectively. It is a member for sealing between the bottom surface B and the side surface). The packing 152 and the packing on the side surface each correspond to a specific example of the "sealing member" in the present invention.

[Operation and action / effect]
(A. Basic operation)
In the spectroscopic aging tester 3 as the weather resistance tester of the present embodiment, light Lout is emitted from the light source 11 in the irradiation unit 1 as needed. Then, under the accelerated environmental condition (accelerated test environment), the sample 9 in the sample storage box 15 is irradiated with the light Lout. By emitting such light Lout for a predetermined test time (for example, about several hours to several thousand hours), the degree of deterioration of each sample 9 (material) is evaluated, and a weather resistance test is performed.

Further, particularly in this spectroscopic aging tester 3, the spectroscopic aging test as one of the weather resistance tests is performed as follows. That is, as shown in FIG. 2, first, the light Lout emitted from the light source 11 in the dark room 10A in the irradiation unit 1 is reflected by the concave mirrors 12a and 12b, and then from the dark room 10A through the slit 13. It is guided to the darkroom 10B side. Next, the light Lout incident on the dark room 10B through the slit 13 is reflected by the concave mirror 12c and then separated by the spectroscope 14 for each wavelength region. Then, the light Lout dispersed in this way is irradiated to the inside of the sample storage box 15 (irradiated surface Si of the sample 9). As a result, the wavelength dependence of photodegradation in sample 9 is evaluated, and a spectroscopic aging test is performed.

Further, in this spectroscopic aging tester 3, in particular, as one of the weather resistance tests, at least two or more of the cycle tests (liquid immersion test, drying test, wet test, spray test, etc.) described later are combined and repeated. Weather resistance test to be carried out: (see FIGS. 5 and 6 described later) is carried out. At this time, as will be described in detail later, the temperature and humidity control unit 2 adjusts the temperature and humidity during the cycle test.

(B. Action / effect)
Next, with reference to FIGS. 4 in addition to FIGS. 1 to 3, the action / effect of the spectroscopic aging tester 3 of the present embodiment will be described in detail in comparison with a comparative example.

(B-1. Comparative example)
FIG. 4 schematically shows a plan configuration example (XY plane configuration example) of the irradiation unit 101 in the spectroscopic aging tester (spectral aging tester 103) according to the comparative example. The spectroscopic aging tester 103 (irradiation unit 101) of this comparative example will be described below in place of the sample storage box 15 in the spectroscopic aging tester 3 (irradiation unit 1) of the present embodiment shown in FIGS. It corresponds to the one provided with the sample storage box 105, and the other configurations are basically the same.

In this sample storage box 105, although the sample 9 is stored inside, unlike the sample storage box 15 of the present embodiment, the liquid W is not stored inside.

In the spectroscopic aging tester 103 of the comparative example having such a configuration, the influence of optical Lout is evaluated in the weather resistance test (spectral aging test). However, in general, one of the properties of the coating film or plastic is that it absorbs water. Therefore, for example, when using a sample 9 made of such a material, in order to realize a weather resistance test (spectral aging test) that more closely simulates the actual environment, the effect of "wetting" (effect of repeated wetting and drying, etc.) It is necessary to evaluate. However, in the spectroscopic aging tester 103 of this comparative example, as described above, the influence of optical Lout is evaluated, and the influence of wetting cannot be evaluated. For these reasons, in this comparative example, the degree of simulation (accuracy) with respect to the actual environment may be insufficient in the weather resistance test (spectral aging test).

(B-2. Embodiment of this present)
On the other hand, in the spectroscopic aging tester 3 (irradiation unit 1) of the present embodiment, as shown in FIGS. 1 to 3, the liquid storage unit 151 for storing the predetermined liquid W together with the sample 9 is provided. , Is provided in the sample storage box 15.

As a result, in the present embodiment, in the weather resistance test (spectral aging test) in which the dispersed light Lout is applied to the irradiated surface Si of the sample 9, in addition to the influence of the light (light Lout), the liquid is contained. The effect of wetting can also be evaluated by using the liquid W in the portion 151 (for example, by immersing the sample 9 in the liquid W). Specifically, unlike the spectroscopic aging tester 103 of the above comparative example, the spectroscopic aging tester 3 of the present embodiment uses the liquid W in addition to the influence of temperature and humidity when irradiated with light Lout. Therefore, the influence of repeated wetting and drying can be evaluated. As a result, in the present embodiment, the degree of simulation (accuracy) with respect to the actual environment is improved in the weather resistance test (spectral aging test) as compared with the above comparative example.

Further, in the spectroscopic aging tester 3 of the present embodiment, as shown in FIG. 1, the liquid tank 21 for storing the liquid W and the liquid W are supplied from the inside of the liquid tank 21 toward the inside of the liquid storage unit 151. A liquid supply mechanism (liquid supply pump 211 and liquid supply pipe Lwin) is provided. As a result, the liquid is automatically supplied into the liquid storage unit 151 (the liquid W is supplied), so that the convenience is improved.

Further, in the spectroscopic aging tester 3 of the present embodiment, as shown in FIG. 1, the liquid recovery mechanism (liquid recovery pipe Lwout, overflow pipe Lwof, and recovery liquid amount adjusting unit 16) and the heater 212 are used. The liquid W is circulated between the inside of the liquid tank 21 and the inside of the liquid storage portion 151 by the above-mentioned liquid supply mechanism and the liquid recovery mechanism. As a result, the temperature of the liquid W circulating between the inside of the liquid tank 21 and the inside of the liquid storage portion 151 is controlled, so that a highly accurate spectroscopic aging test can be realized.

Further, as the liquid W, as described above, water or a corrosive solution can be mentioned, but when a corrosive solution is used as the liquid W, the deterioration of the sample 9 can be further promoted. It becomes possible to perform a more efficient weather resistance test (spectral aging test).

Further, in the spectroscopic aging tester 3 of the present embodiment, as shown in FIG. 1, a predetermined gas (wet air Aw or dry air Ad) whose temperature and humidity are adjusted is supplied into the liquid storage unit 151. The gas supply mechanism described above is provided. As a result, in the liquid storage unit 151 (sample storage box 15), in addition to the liquid immersion test, other tests (for example, a drying test and a wet test described later) can be performed, so that the actual environment can be further improved. It is possible to perform a simulated weather resistance test.

In addition, in the spectroscopic aging tester 3 of the present embodiment, as shown in FIG. 3, the side surface, the bottom surface B, and the bottom surface B of the liquid storage unit 151 except for the irradiated surface Si side of the sample 9 are used. The packing 152, the above-mentioned packing on the side surface, and the lid C are provided. As a result, the sample storage box 15 can be directly applied (attached and used) to an existing weather resistance tester (spectral aging tester) such as the weather resistance tester (spectral aging tester 103) of the comparative example. Therefore, convenience is improved. Further, since the side surface of the liquid storage portion 151 is not provided on the Si side of the irradiated surface of the sample 9, a decrease in the amount of light (loss of light amount) of the light Lout incident on the liquid storage portion 151 is prevented, which is more efficient. It is possible to perform a weather resistance test (spectral aging test).

Further, in the spectroscopic aging tester 3 of the present embodiment, as shown in FIGS. 2 and 3, in the main body of the tester, the Si side of the irradiated surface of the sample 9 in the liquid storage portion 151 is separated by the spectroscope 14. It is composed of a light transmitting member 150 that transmits the light Lout. As a result, the liquid W is prevented from entering the spectroscopic aging tester 3, and the decrease in the amount of light (loss of the amount of light) of the light Lout incident on the liquid storage unit 151 is suppressed, which is also more efficient. It is possible to perform a weather resistance test (spectral aging test).

(C. Operation in cycle test)
Subsequently, with reference to FIGS. 5 and 6 in addition to FIGS. 1 to 3, the operation of the spectroscopic aging tester 3 during the above-mentioned cycle test will be described in detail.

5 and 6 are schematic representations of an example of a cycle test according to the present embodiment, respectively. As shown in FIGS. 5 and 6, in this example of the cycle test, the steps shown in 1 to 6 below are repeatedly executed (see arrows P11 and P12 in FIGS. 5 and 6). The temperature conditions and the like in each step shown in FIGS. 5 and 6 are merely examples, and are not limited to these temperature conditions and the like.
1. 1. Liquid immersion test: Temperature of immersion liquid (liquid W): 40 ° C
2. Drying test ... Dry air Ad temperature: 40 ° C
3. 3. Wetness test: Wet air Aw temperature: 40 ° C, Humidity air Aw humidity: 98% RH
4. Drying test ... Dry air Ad temperature: 40 ° C
5. Spray test: Temperature of spray liquid (liquid W): 40 ° C
6. Drying test ... Dry air Ad temperature: 40 ° C

<Liquid immersion test>
First, for example, as shown in FIGS. 5 and 6, a liquid immersion test as one of the weather resistance tests is performed. That is, in a state where the liquid W (immersion liquid temperature: 40 ° C. in this example) as the immersion liquid is supplied from the liquid supply pipe Lwin into the liquid storage portion 151 and the sample 9 is immersed in the liquid W, the liquid is immersed. The test is performed. In this way, the spectroscopic aging tester 3 of the present embodiment can easily realize the liquid immersion test.

<Drying test>
Then, for example, as shown in FIGS. 5 and 6, a drying test as one of the weather resistance tests is performed. That is, in a state where the liquid W is discharged from the liquid storage unit 151, the sample 9 is exposed to drying conditions (dry air Ad (dry air temperature: 40 ° C. in this example) from the air supply pipe Lain into the liquid storage unit 151. ) Is supplied), and the drying test is executed. In this way, in the spectroscopic aging tester 3 of the present embodiment, the drying test can be easily realized.

In addition, in each of the examples of the cycle test shown in FIGS. 5 and 6, such a drying test is performed immediately after the wet test and the spray test described below, respectively.

<Humidity test>
Subsequently, as shown in FIGS. 5 and 6, for example, a wet test as one of the weather resistance tests is performed. That is, the sample 9 is exposed to a wet condition in a state where the liquid W is discharged from the liquid storage portion 151 (wet air Aw (wet air temperature: 40 ° C. in this example) from the air supply pipe Line into the liquid storage portion 151). , Humidity of moist air: 98% RH) is supplied in this example) to perform the moist test. In this way, in the spectroscopic aging tester 3 of the present embodiment, the wetness test can be easily realized.

<Spray test>
Further, for example, as shown in FIGS. 5 and 6, a spray test as one of the weather resistance tests is performed. That is, the spray test is executed by injecting the liquid W (spray liquid temperature: 40 ° C. in this example) as the spray liquid onto the sample 9 in the liquid storage portion 151. It should be noted that such liquid injection is performed using, for example, the liquid injection mechanism 17 or the like described in the modified example 4 described later. In this way, the spectroscopic aging tester 3 of the present embodiment can easily realize the spray test.

As described above, in the spectroscopic aging tester 3 of the present embodiment, the cycle test is executed by combining at least two or more of the liquid immersion test, the drying test, the wet test and the spray test as described above. To. As a result, in the present embodiment, a cycle test in which various tests are combined can be executed, so that a weather resistance test simulating the actual environment can be further performed.

Further, among the cycle tests shown in FIGS. 5 and 6, in particular, in the example of the cycle test shown in FIG. 6, the light Lout dispersed by the spectroscope 14 is irradiated to the irradiated surface Si of the sample 9 or A cycle test is performed by further combining the non-irradiated states. Specifically, in the example of the cycle test shown in FIG. 6, such light Lout irradiation is performed during the drying test (light irradiation: "presence" state). On the other hand, during the liquid immersion test, the wet test and the spray test, such light Lout irradiation is not performed (light irradiation: "none" state). In the example of the cycle test shown in FIG. 5, such irradiation of light Lout (light irradiation) is always performed in any of the tests.

As described above, in the example shown in FIG. 6, since the influence of the presence or absence of light irradiation can be further added during the cycle test, it is possible to further perform the weather resistance test simulating the actual environment. Become.

Further, as shown by arrows P21 and P22 in FIGS. 5 and 6, when the above-mentioned corrosive solution is used as the liquid W, for example, in each of these cycle tests, the following pureness is obtained. The cleaning step using the above may be performed between the liquid immersion test and the drying test. That is, after the sample 9 is immersed in the corrosive solution (liquid W) in the liquid storage unit 151 and the liquid immersion test is executed, the sample 9 in the liquid storage unit 151 is immersed in pure water. The cleaning step (see arrows P21 and P22) may be performed.

When such a cleaning step using pure water is performed after the liquid immersion test, it is possible to prevent crystals from being formed on the surface of the sample 9 due to the corrosive solution, and as a result, , A highly accurate spectroscopic aging test is realized.

As described above, in the present embodiment, in the spectroscopic aging tester 3, the sample accommodating box 15 is provided with the liquid accommodating portion 151 for accommodating the predetermined liquid W together with the sample 9, so that the spectroscopic aging test can be performed. At that time, the influence of wetting can be evaluated in addition to the influence of light. Therefore, it is possible to perform a weather resistance test that more closely simulates the actual environment.

Wetness evaluation becomes feasible.

In this modified example as well, for example, as shown by arrows P3 and broken lines in FIG. 9, the liquid W is halfway filled in the liquid accommodating portion 151B as in the above-mentioned modified example 1 (see FIG. 7).

The injection is performed in 151 (or the liquid accommodating portions 151A and 151B). Further, as shown in FIG. 10, the liquid injection mechanism 17 moves the liquid W from above the sample 9 to the irradiated surface Si side (front side of the sample 9) in the liquid storage portion 151 (151A, 151B). The liquid W is sprayed so that the liquid W flows.

In the modified example 4 with such a configuration, as compared with the case where the liquid W is supplied from the lateral direction (horizontal direction, the X-axis direction in FIG. 10) of the sample 9 in the liquid storage portion 151 (151A, 151B), for example. , It becomes as follows.
