Description

  The present invention relates to a weathering tester applied to, for example, a spectral aging test.

  The weather resistance tester artificially reproduces accelerated environmental conditions (acceleration test environment) by irradiating various samples with light from a light source (artificial light source) replacing the sun in addition to temperature and humidity conditions and water spray. This is an apparatus for evaluating the degree of deterioration of the sample (material) and the like (performing a weathering test).

  Moreover, in such a weather resistance test, especially a spectral aging test is a test which evaluates the wavelength dependence of the photodegradation in a sample (for example, refer to patent documents 1).

JP-A-7-234181

  By the way, in such a weather resistance tester, it is generally required to conduct a weather resistance test which simulates a real environment.

  Therefore, it is desirable to provide a weathering tester capable of performing a weathering test more simulating a real environment.

  The weathering tester according to one embodiment of the present invention is a light source unit that emits light, a sample storage box that stores a sample, and light that is dispersed by dispersing light from the light source unit for each wavelength region. And a spectroscope for irradiating light to the surface to be irradiated of the sample. The sample storage box has a liquid storage portion for storing a predetermined liquid together with the sample.

  In the weathering 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. Thereby, in the weathering test (spectral aging test) of irradiating the light to which the light is dispersed with respect to the irradiated surface of the sample, the liquid in the liquid storage unit is used in addition to the influence of light (for example, ), It is possible to evaluate the influence of wetting.

  The weather resistance tester according to one embodiment of the present invention may further include 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. In this case, since the liquid is automatically supplied into the liquid storage unit, the convenience is improved.

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

  In addition, a liquid ejecting mechanism may be further provided which ejects the liquid supplied by the liquid supply mechanism so as to flow from above the sample to the irradiated surface side in the liquid storage unit. In this case, for example, variation in temperature rise of the liquid due to radiant heat of light (variation in temperature rise in the horizontal direction) as compared to the case where the liquid is supplied from the lateral direction (horizontal direction) of the sample in the liquid storage unit But can be suppressed. As a result, a highly accurate spectral aging test is realized.

  The weather resistance tester according to one embodiment of the present invention may further include a gas supply mechanism for supplying predetermined gases, each of which has been adjusted in temperature and humidity, into the liquid storage unit. In this case, in addition to the liquid immersion test, other tests (for example, a drying test, a wet test, etc.) can be performed in the liquid storage unit (sample storage box), so that the actual environment is further simulated. It is possible to carry out the weathering test.

  In addition, a liquid immersion test performed in a state in which the sample is immersed in the liquid in the liquid storage unit, a drying test performed by exposing the sample to a drying condition in a state in which the liquid is discharged from the liquid storage unit, and And at least two or more of a wet test performed by exposing the sample to a wet condition and a spray test performed in a state in which the liquid in the liquid storage unit is sprayed A cycle test may be performed by combining the tests. In this case, a cycle test combining various tests can be performed, and a weather resistance test simulating a real environment can be performed.

  In this case, the cycle test may be performed by further combining the state where the light dispersed by the spectroscope is irradiated or not irradiated on the surface to be irradiated of the sample. In this case, in the cycle test, the influence of the presence or absence of light irradiation can be further added, so that it is possible to conduct a weather resistance test simulating the actual environment even more.

  Here, examples of the liquid include water or a corrosive solution. When a corrosive solution is used as the liquid, deterioration of the sample can be further accelerated, so that a more efficient weathering test (spectral aging test) can be performed. When the liquid is a corrosive solution, the sample is immersed in the corrosive solution in the liquid storage unit and the liquid immersion test is performed, and then the sample in the liquid storage unit is immersed in pure water. A washing step may be performed. In this case, the formation of crystals on the surface of the sample due to the corrosive solution is prevented, and as a result, a highly accurate spectral aging test is realized.

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

  Here, the liquid containing portion is a side surface provided except the irradiated surface side of the sample, a bottom surface provided on the lower side of the sample, and a tester main body and a liquid containing portion located on the irradiated surface side of the sample And a lid provided on the upper side of the sample. In this case, the sample storage box can be applied (attached and used) to the existing weathering tester (spectral aging tester) as it is, and the convenience is improved. In addition, since the side surface of the liquid storage unit is not provided on the irradiated surface side of the sample, the decrease in the amount of light entering the liquid storage unit is prevented, and a more efficient weathering test (spectral aging test) It will be 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 below the sample, and a lid provided above the sample. . Also in this case, the sample storage box can be applied as it is to the existing weathering tester (spectral aging tester), and the convenience is improved. In addition, since the side surface of the liquid storage portion is provided also on the irradiated surface side of the sample, a sealing member or the like is not required (the leakage of the liquid is not taken into consideration). Can be realized.

  In the weathering tester according to the embodiment of the present invention, even if the irradiated surface side of the sample in the liquid storage unit is constituted by the light transmitting member which transmits the light dispersed by the spectroscope in the tester main body. Good. In such a case, a decrease in the amount of light incident on the liquid storage portion (loss of light amount) can be suppressed without the liquid entering the inside of the weather resistance tester, so a more efficient weather resistance test (spectral aging test) It is possible to do

  In addition to providing a sample mounting jig for mounting the sample in the liquid storage unit, the sample mounting jig may have an irradiation wavelength scale indicating the reference of the irradiation wavelength of the light dispersed by the spectroscope. . In this case, when the sample is mounted in the liquid storage unit, the position adjustment of the wavelength of the light irradiated to the surface to be irradiated can be easily performed, and the convenience is improved.

  According to the weather resistance tester according to the embodiment of the present invention, the liquid storage portion for storing the predetermined liquid together with the sample is provided in the sample storage box, so that light of the light during the spectral aging test can be obtained. In addition to the effects, the effects of wetting can also be evaluated. Therefore, it is possible to conduct a weather resistance test simulating the actual environment.

[Detailed Configuration of Sample Storage Box 15]
Subsequently, a detailed configuration example of the above-described sample storage box 15 will be described with reference to FIG. 3 in addition to FIGS.

  FIG. 3 schematically shows a detailed configuration example of the sample storage box 15 and the like in a cross-sectional view (Y-Z cross-sectional view).

It is constituted by a member 150.

Further, as shown in FIG. 3, the side surface of the liquid storage portion 151 is provided excluding the irradiated surface Si side of the sample 9.

Further, packing not shown along the Z-axis is also provided on the side surface (side surface parallel to the paper surface) in the liquid storage portion 151, and in the first and second modifications (FIG. 7, FIG. 8) described later. It is similar.

[Operation and action / effect]
(A. Basic operation)
In the spectral 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 necessary. Then, the light Lout is irradiated to the sample 9 in the sample storage box 15 under the accelerated environmental conditions (accelerated test environment). The radiation degree of such light Lout is performed for a predetermined test time (for example, about several hours to several thousand hours), the degree of deterioration of each sample 9 (material) and the like are evaluated, and a weather resistance test is performed.

  Further, in particular, in this spectral aging tester 3, a spectral aging test as one of weathering tests is performed as follows. That is, as shown in FIG. 2, first, after 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, from the dark room 10A via the slit 13. It is led to the dark room 10B side. Next, the light Lout that has entered the dark room 10B via the slit 13 is reflected by the concave mirror 12c, and then split by the spectroscope 14 into wavelength regions. Then, the light Lout thus dispersed is emitted to the inside of the sample storage box 15 (the irradiated surface Si of the sample 9). Thereby, the wavelength dependency of the photodegradation in the sample 9 is evaluated, and a spectral aging test is performed.

  Furthermore, in this spectral aging tester 3, in particular, as one of the weathering tests, the cycle test described later (a combination of at least two or more of the liquid immersion test, the drying test, the wet test, the spray test, etc.) is repeated. Weathering test to be performed: see FIG. 5 and FIG. At this time, although the details will be described later, the temperature and humidity control unit 2 adjusts the temperature and humidity in the cycle test.

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

(B-1. Comparative example)
FIG. 4: represents typically the example of a plane structure (example of XY plane structure) of the irradiation unit 101 in the spectral aging tester (spectral aging tester 103) which concerns on a comparative example. The spectral aging tester 103 (irradiation unit 101) of this comparative example will be described below in place of the sample storage box 15 in the spectral aging tester 3 (irradiation unit 1) of the present embodiment shown in FIGS. It corresponds to what provided the sample storage box 105, and the other structure is fundamentally 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 spectral aging tester 103 of the comparative example having such a configuration, the influence of the light Lout is evaluated in the weather resistance test (spectral aging test). However, generally, the property of a coating film or plastic includes absorbing water. Therefore, for example, in the case of using sample 9 of such a material, in order to realize a weather resistance test (spectral aging test) simulating a real environment, the effect of "wetting" (the effect of repeated wetting and drying, etc.) It is necessary to evaluate the However, in the spectral aging tester 103 of this comparative example, as described above, the influence of the light Lout is evaluated, and the influence of the wetting can not be evaluated. From these things, in this comparative example, in a weather resistance test (spectral aging test), there is a possibility that the degree (accuracy) of simulation with respect to a real environment may become insufficient.

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

  Thus, in the present embodiment, in the case of a weather resistance test (spectral aging test) in which the light Lout thus dispersed is irradiated onto the surface to be irradiated Si of the sample 9, in addition to the influence of light (light Lout), liquid accommodation. The influence of the 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, in the spectral aging tester 3 of the present embodiment, unlike the spectral aging tester 103 of the comparative example, the liquid W is used in addition to the influence of temperature and humidity when the light Lout is irradiated. The effect of repeated wetting and drying can also be evaluated. As a result, in the present embodiment, the degree of simulation (accuracy) with respect to the actual environment is improved in the weathering test (spectral aging test), as compared with the comparative example.

  Further, in the spectral aging tester 3 of the present embodiment, as shown in FIG. 1, the liquid tank 21 storing the liquid W and the liquid W supplied from the inside of the liquid tank 21 into the liquid storage unit 151 The liquid supply mechanism (liquid supply pump 211 and liquid supply piping Lwin) is provided. As a result, liquid is automatically supplied into the liquid storage unit 151 (liquid W is supplied), and convenience is improved.

  Furthermore, in the spectral aging tester 3 according to the present embodiment, as shown in FIG. 1, the liquid recovery mechanism (liquid recovery pipe Lwout, overflow pipe Lwof and recovered liquid amount adjustment unit 16) described above, and heater 212 and 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-described liquid supply mechanism and the liquid recovery mechanism. Thus, 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 spectral aging test is realized.

  In addition, as the liquid W, as described above, water or a corrosive solution may be mentioned. When a corrosive solution is used as the liquid W, the deterioration of the sample 9 can be further promoted. It is possible to conduct a more efficient weathering test (spectral aging test).

  Furthermore, in the spectral 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 above-mentioned gas supply mechanism is provided. As a result, in addition to the liquid immersion test, other tests (for example, a drying test, a wet test, etc. described later) can be performed in the liquid storage unit 151 (sample storage box 15), so the actual environment can be further improved. It is possible to conduct a simulated weathering test.

  In addition, in the spectral aging tester 3 of the present embodiment, as shown in FIG. 3, in the liquid storage portion 151, the side surface provided except the irradiated surface Si side of the sample 9, the bottom surface B, The packing 152, the packing on the side face mentioned above, and the lid C are provided. Thereby, the sample storage box 15 can be applied (attached and used) as it is to an existing weathering tester (spectral aging tester) such as a weathering tester (spectral aging tester 103) of the comparative example. Therefore, the convenience is improved. In addition, since the side surface of the liquid storage portion 151 is not provided on the irradiated surface Si side of the sample 9, the reduction in the light amount (the loss of the light amount) of the light Lout incident on the liquid storage portion 151 is prevented, which is more efficient. Weather resistance test (spectral aging test) can be performed.

  Further, in the spectral aging tester 3 of the present embodiment, as shown in FIG. 2 and FIG. 3, in the tester main body, the irradiated surface Si side of the sample 9 in the liquid storage unit 151 The light transmitting member 150 is configured to transmit the received light Lout. Thereby, the liquid W is prevented from entering the spectral aging tester 3 and the decrease in the light amount (the loss of the light amount) of the light Lout entering the liquid storage portion 151 is suppressed. It is possible to carry out a specific weathering test (spectral aging test).

(C. Operation in cycle test)
Next, with reference to FIG. 5 and FIG. 6 in addition to FIG. 1 to FIG. 3, the operation in the above-mentioned cycle test in the spectral aging tester 3 will be described in detail.

Each of FIG. 5 and FIG. 6 schematically shows an example of the cycle test according to the present embodiment. As shown in FIG. 5 and FIG. 6, in the example of this cycle test, the following steps 1 to 6 are repeatedly performed (see arrows P11 and P12 in FIGS. 5 and 6). The temperature conditions and the like in the steps shown in FIGS. 5 and 6 are merely examples, and the present invention is not limited to these temperature conditions and the like.
1. Liquid immersion test ... Temperature of immersion liquid (liquid W): 40 ° C
2. Drying test ... Temperature of drying air Ad: 40 ° C
3. Humidity test ... Humid air Aw temperature: 40 ° C, Humid air Aw humidity: 98% RH
4. Drying test ... Temperature of drying air Ad: 40 ° C
5. Spray test ... Temperature of spray liquid (liquid W): 40 ° C
6. Drying test ... Temperature of drying air Ad: 40 ° C

<Liquid immersion test>
First, for example, as shown in FIGS. 5 and 6, a liquid immersion test as one of weathering tests is performed. That is, in the state in which the liquid W (immersion liquid temperature: 40 ° C. in this example) as the immersion liquid is supplied from the liquid supply piping Lwin into the liquid storage unit 151 and the sample 9 is immersed in the liquid W A test is performed. Thus, in the spectral aging tester 3 of the present embodiment, a liquid immersion test can be easily realized.

<Drying test>
Then, a drying test as one of the weathering tests is performed, for example, as shown in FIG. 5 and FIG. That is, in a state where the liquid W is discharged from the liquid storage portion 151, the sample 9 is exposed to the drying condition (from the air supply pipe Lain to the liquid storage portion 151, dry air Ad (dry air temperature: 40 ° C. in this example). The drying test is performed by supplying). Thus, in the spectral aging tester 3 of the present embodiment, the drying test can be easily realized.

  Note that such a drying test is to be performed immediately after the wet test and the spray test described below in the examples of the cycle tests shown in FIGS. 5 and 6, respectively.

<Wetting test>
Subsequently, as shown in, for example, FIGS. 5 and 6, a wet test as one of weathering tests is performed. That is, in a state where the liquid W is discharged from the liquid storage portion 151, the sample 9 is exposed to wet conditions (from the air supply pipe Lain to the liquid storage portion 151, wet air Aw (wet air temperature: 40 ° C. in this example). (Humid air humidity: 98% RH in this example), the wetting test is performed. Thus, in the spectral aging tester 3 of the present embodiment, the wet test can be realized easily.

<Spray test>
Also, for example, as shown in FIGS. 5 and 6, a spray test is performed as one of the weathering tests. That is, the spray test is performed by injecting the liquid W (spray liquid temperature: 40 ° C. in this example) as the spray liquid on the sample 9 in the liquid storage unit 151. Note that such liquid ejection is performed using, for example, a liquid ejection mechanism 17 described in the fourth modification described later. Thus, in the spectral aging tester 3 of the present embodiment, the spray test can be easily realized.

  Thus, in the spectral aging tester 3 of the present embodiment, a cycle test is performed 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. Ru. As a result, in the present embodiment, a cycle test combining various tests can be performed, so that it is possible to perform a weather resistance test further simulating a real environment.

  Further, in the example of the cycle test shown in FIG. 6 among the cycle tests shown in FIG. 5 and FIG. 6, the light Lout dispersed by the spectroscope 14 is irradiated to the irradiated surface Si of the sample 9 or The cycle test is performed by further combining the non-irradiated state. Specifically, in the example of the cycle test shown in FIG. 6, such irradiation of the light Lout is performed in the drying test (light irradiation: state of “present”). On the other hand, in the case of the liquid immersion test, the wet test and the spray test, such irradiation of the light Lout is not performed (light irradiation: "non-existence" state). In the example of the cycle test shown in FIG. 5, such irradiation (light irradiation) of the light Lout 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 in the cycle test, it is possible to carry out the weather resistance test simulating the actual environment even more. Become.

  Further, as indicated by arrows P21 and P22 in FIGS. 5 and 6, in these cycle tests, for example, when the corrosive solution described above is used as the liquid W, the following pure ones are used: The washing 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 container 151 and the liquid immersion test is performed, the sample 9 in the liquid container 151 is immersed in pure water. A washing step (see arrows P21 and P22) may be performed.

  When the cleaning process using such pure water is performed after the liquid immersion test, generation of crystals on the surface of the sample 9 due to the corrosive solution is prevented, and the result is Accurate spectral aging test is realized.

  As described above, in the present embodiment, in the spectral aging tester 3, the liquid storage portion 151 for storing the predetermined liquid W together with the sample 9 is provided in the sample storage box 15. In addition to the influence of light, the influence of wetting can also be evaluated. Therefore, it is possible to conduct a weather resistance test simulating the actual environment.
