Abstract
Description
本発明は、ラジカル化したガスと光を利用した耐候試験方法と、それを実施するための耐候試験機に関する。 The present invention relates to a weathering test method using radicalized gas and light, and a weathering test machine for carrying out the same.
近年、原材料や製品の耐久性に関する品質向上はめざましく、長期に亘って劣化しないものもあり、従来の耐候試験機の劣化速度では遅すぎるという問題が生じている。そのため、劣化の促進性をさらに高めた耐候試験機が求められている。 In recent years, quality improvements related to the durability of raw materials and products have been remarkable, and some have not deteriorated over a long period of time, resulting in a problem that the deterioration rate of conventional weathering test machines is too slow. Therefore, there is a demand for a weathering tester that further enhances the acceleration of deterioration.
従来は、紫外線蛍光灯、紫外線カーボンアーク灯、サンシャインカーボンアーク灯、キセノンアークランプ、メタルハライドアークランプ等を利用した耐候試験機や過酸化水素を利用した耐候試験機などを使用していた。また最近、促進性に優れたリモートプラズマ耐候試験機が開発された。 Conventionally, a weathering tester using an ultraviolet fluorescent lamp, an ultraviolet carbon arc lamp, a sunshine carbon arc lamp, a xenon arc lamp, a metal halide arc lamp, or a weathering test machine using hydrogen peroxide has been used. Recently, a remote plasma weather tester with excellent acceleration has been developed.
従来の耐候試験機は、その装置固有の条件すなわち、照射する分光分布、照射強度、温度、湿度、雰囲気の微量劣化作用成分などと、試料の劣化特性を考慮して選択、使用していた。 A conventional weathering tester has been selected and used in consideration of the conditions specific to the apparatus, that is, the spectral distribution to be irradiated, irradiation intensity, temperature, humidity, components that cause a slight deterioration of the atmosphere, and the deterioration characteristics of the sample.
リモートプラズマ耐候試験機は、減圧下で高周波電力を印加してプラズマを発生させ、ラジカル化したガスを生成し試料に作用させることによって試料の促進劣化を促すものである。
酸素ガスを利用した場合には、プラズマ中で、以下の状態変化が起こると考えられる。
Ｏ２ ＋ ｅ− → Ｏ + Ｏ （１）
Ｏ２ ＋ ｅ− → Ｏ- ２ （２）
これら（１）、（２）は、一般に酸素ラジカルあるいは、活性酸素種と呼ばれるもので、非常に酸化力が強く、物質を劣化させる作用が強い。リモートプラズマ耐候試験機はこのメカニズムを利用して試料を劣化促進させるもので、試料劣化の速度がきわめて速い。
The remote plasma weathering tester promotes accelerated deterioration of a sample by applying high-frequency power under reduced pressure to generate plasma, generating radicalized gas, and acting on the sample.
When oxygen gas is used, the following state changes are considered to occur in the plasma.
O 2 + e − → O + O (1)
O 2 + e − → O - 2 (2)
These (1) and (2) are generally called oxygen radicals or active oxygen species, and have a very strong oxidizing power and a strong effect of degrading substances. The remote plasma weathering tester uses this mechanism to accelerate sample degradation, and the rate of sample degradation is extremely fast.
しかしながら、前述の従来耐候試験機では、試験結果が得られるまでの期間が数ヶ月に及ぶものもある。また、急速に劣化が生ずる試験機はあるが、対象とする試料によっては自然環境下における暴露試験の結果と異なる挙動を示す試験装置がある。 However, some of the above-mentioned conventional weathering test machines take several months until the test results are obtained. In addition, although there are test machines that rapidly deteriorate, there are test apparatuses that exhibit behaviors that differ from the results of exposure tests in the natural environment, depending on the target sample.
以上に述べた耐候試験方法で試験を行った場合には、結果が明らかになるまでには長期間を要し、開発スピードの短縮が要求される今日においては、製品の開発計画に支障をきたすという問題がある。また、試料によっては、自然環境下における劣化の挙動と一致しないという問題がある。 When testing with the weather resistance test method described above, it takes a long time for the results to become clear, and today there is a need to shorten the development speed, which hinders product development planning. There is a problem. In addition, there is a problem that some samples do not match the deterioration behavior in the natural environment.
本発明はこのような従来の問題を解決するものであり、光、温度、湿度等の劣化因子の他に、新たに酸素などのラジカル化したガスを劣化因子として加えることによって、より自然環境に忠実な再現性を有し、かつ劣化因子の状態を実環境の場合より強化して超促進性を有する耐候試験を実現することを目的とするものである。 The present invention solves such a conventional problem, and in addition to deterioration factors such as light, temperature, and humidity, newly added radicalized gas such as oxygen as a deterioration factor makes it more natural. The object is to realize a weather resistance test that has faithful reproducibility and has a super-acceleration property by strengthening the state of deterioration factors as compared with the actual environment.
自然界では、空気中の酸素に紫外線を含んだ太陽光が作用することで、ラジカル化したガスである酸素ラジカルが常に生成しては消滅している。この酸素ラジカルは、酸化作用が強いので、自然界においても物質の劣化作用に影響していると考えられる。したがって、光、温度、湿度等の従来の劣化因子に、ラジカル化したガスも劣化因子として加えることで、より自然環境に近い再現性の高い耐候試験が可能となり、かつラジカル化したガスの量を増やすことでさらに劣化促進性の高い耐候試験が可能となる。 In nature, sunlight containing ultraviolet rays acts on oxygen in the air, and oxygen radicals, which are radicalized gases, are always generated and disappear. Since this oxygen radical has a strong oxidizing action, it is considered that the oxygen radical also has an influence on the degradation action of the substance in nature. Therefore, by adding radicalized gas as a degradation factor to conventional degradation factors such as light, temperature, humidity, etc., it becomes possible to perform a weather resistance test with high reproducibility closer to the natural environment, and the amount of radicalized gas can be reduced. By increasing the number, it becomes possible to perform a weathering test with a higher deterioration promoting property.
この原理に基づいて、光、温度、湿度等の劣化因子の他に、新たにラジカル化したガスの劣化因子を加えた、より自然環境に近い優れた再現性を有し、かつ促進性に優れた耐候試験方法、及びこの耐候試験方法を実施するための耐候試験機を提供する。
すなわち、試料の表面を劣化促進させるために、光源から太陽光を模擬した光または劣化に寄与する波長を含む光と、高周波電力の印加によってプラズマを発生させ、ラジカル化したガスを生成し、試料表面に作用させる。
Based on this principle, in addition to degradation factors such as light, temperature, humidity, etc., a newly radicalized gas degradation factor is added, and it has excellent reproducibility closer to the natural environment and excellent acceleration. A weather resistance test method and a weather test machine for carrying out the weather test method are provided.
In other words, in order to promote the deterioration of the surface of the sample, light that simulates sunlight from a light source or light that includes a wavelength that contributes to deterioration and plasma is generated by application of high-frequency power to generate radicalized gas, Act on the surface.
本発明の耐候試験機は、紫外線透過率のよいガラスでできた直方体または筒状の試験槽を備え、その上端は封止されており、前記試験槽の外壁の近傍にプラズマを発生させるための一対の電極板が対向して設置され、高周波電源に接続されている。
前記試験槽の下端は開口されており、前記排気台に密着させて設置する。前記排気台には試料台を挿入するための貫通孔があり、前記排気台の下方から前記試料台を挿入する。前記試料台の一部は前記排気台と密着し、前記試験槽内の気密性を保持し、真空あるいは減圧状態に保つ構造になっている。
また、前記試験槽内に試料を装着するときは、試験を停止した状態で、試料台昇降装置により、前記試料台の上部を前記排気台の下部より下に移動させ、試料を前記試料台に装着した後、試料台昇降装置で試料台を上昇させ、元の位置に戻す。
前記試験槽内は一定の低圧状態を保つため、バルブを介して真空排気ポンプと接続されている。
前記電極板より上部の前記試験槽の一部にはガス導入口があり、ガス流量計によって、一定流量のガスが前記試験槽内に送入される。
前記光源に用いる前記ランプは、紫外、可視部の分光分布が太陽光に近似したキセノンランプや、紫外部に多大なエネルギーを持つメタルハライドランプ、紫外部の特定の波長に豊富なエネルギーを持つ蛍光灯、カーボンアークランプ、発光ダイオードなどが考えられ、このうちのひとつ又は複数から採用される。これにより、太陽光を模擬した光または光照射劣化に寄与する波長を含む光を試料に照射することが可能となる。
また、所望の分光分布をもった光を照射する場合には、少なくとも一種類以上のフィルターを介して光を試料に照射することが好ましい。
また、照射強度を均一に調整する場合、または照射強度を調整する場合は、レンズを介して光を試料に照射することが好ましい。
ラジカル化したガスの生成は、前記ガス導入口からガスを導入しながら、前記試験槽内の圧力を一定に保ち、前記電極板に高周波電力を印加し、プラズマを発生させて行い、前記試験槽内の電極よりも下部の位置に流下する。前記試料台はこの位置の一部に存在する。
The weathering tester of the present invention includes a rectangular parallelepiped or a cylindrical test tank made of glass having a high ultraviolet transmittance, and its upper end is sealed, for generating plasma in the vicinity of the outer wall of the test tank. A pair of electrode plates are installed facing each other and connected to a high-frequency power source.
The lower end of the test tank is opened and is installed in close contact with the exhaust stand. The exhaust table has a through hole for inserting a sample table, and the sample table is inserted from below the exhaust table. A part of the sample table is in close contact with the exhaust table, maintains the airtightness in the test chamber, and maintains a vacuum or a reduced pressure state.
In addition, when mounting the sample in the test chamber, the test is stopped and the upper part of the sample stage is moved below the lower part of the exhaust table by the sample stage lifting device, and the sample is placed on the sample stage. After mounting, the sample table is raised by the sample table lifting device and returned to the original position.
In order to maintain a constant low pressure in the test chamber, it is connected to an evacuation pump through a valve.
A part of the test tank above the electrode plate has a gas inlet, and a gas flow meter supplies a constant flow of gas into the test tank.
The lamp used for the light source is a xenon lamp whose spectral distribution in the ultraviolet and visible parts approximates that of sunlight, a metal halide lamp having a large energy in the ultraviolet part, and a fluorescent lamp having abundant energy in a specific wavelength in the ultraviolet part. Carbon arc lamps, light emitting diodes, and the like are conceivable, and one or more of them are adopted. This makes it possible to irradiate the sample with light simulating sunlight or light including a wavelength that contributes to light irradiation deterioration.
In addition, when irradiating light having a desired spectral distribution, it is preferable to irradiate the sample with light through at least one type of filter.
Moreover, when adjusting irradiation intensity uniformly or adjusting irradiation intensity, it is preferable to irradiate a sample with light through a lens.
The radicalized gas is generated by introducing a gas from the gas introduction port while maintaining a constant pressure in the test tank, applying high-frequency power to the electrode plate, and generating plasma. It flows down to a position below the inner electrode. The sample stage exists at a part of this position.
光は、前記試験槽の上方から前記光透過性ガラスを介して、ほぼ垂直に試料に照射することが効率的であり、好ましい。 It is efficient and preferable to irradiate the sample almost vertically from above the test tank through the light-transmitting glass.
また、円環状の光源を、前記試験槽の外周で、前記電極板と前記試料台の間に配置することにより、前記光源を試料に近づけ放射照度の高い均一な光を照射することが可能となる。
また、ひとつの円環状光源の代わりに、複数のランプを前記試験槽の外周に配置した構造でもよい。
Further, by arranging an annular light source between the electrode plate and the sample stage on the outer periphery of the test chamber, it is possible to irradiate uniform light with high irradiance by bringing the light source closer to the sample. Become.
Moreover, the structure which has arrange | positioned the some lamp | ramp on the outer periphery of the said test chamber instead of one annular light source may be sufficient.
また例えば長方形状の試料を扱う場合、前記試料台に水平に広い面を接触させて装着すると安定するが、前記試料台に対して前記試料を垂直に装着することによって、前記試料の表裏に同時にラジカル化したガスを接触させ、前記試験槽の外部から光を試料面に照射することも可能である。このように、前記試料表裏に対して前記光源を対向して配置すると、光放射の効率が最大となる。
また、前記ひとつの円環状の光源を用いる場合、又は複数のランプを前記試験槽の外周に並べて配置する場合、前記試料の表裏を同時に光照射することが可能となる。
In addition, for example, when handling a rectangular sample, it is stable if the sample table is mounted with a wide surface in contact with the sample table. However, by mounting the sample vertically on the sample table, It is also possible to contact the radicalized gas and irradiate the sample surface with light from the outside of the test chamber. As described above, when the light source is disposed opposite to the front and back of the sample, the efficiency of light emission is maximized.
In addition, when the single annular light source is used, or when a plurality of lamps are arranged side by side on the outer periphery of the test chamber, the front and back of the sample can be irradiated simultaneously.
さらに、前記試料台に回転機構を備え、水平方向に回転させることにより、前記試料へのラジカル化したガスの接触と光の照射を均一化することが好ましい。
また前記試料台に温度制御機構を設け、前記試料の温度を制御することがさらに好ましい。
Furthermore, it is preferable that the sample stage is provided with a rotation mechanism, and the contact of the radicalized gas and the light irradiation to the sample are made uniform by rotating in the horizontal direction.
More preferably, a temperature control mechanism is provided on the sample stage to control the temperature of the sample.
酸素ラジカルを利用するためには、前記ガス導入口から供給されるガスは、酸素又はその混合気体であることが好ましい。 In order to use oxygen radicals, the gas supplied from the gas inlet is preferably oxygen or a mixed gas thereof.
上記の光照射ラジカル耐候試験方法を実施するために、光照射ラジカル耐候試験機を開発した。
In order to carry out the above light irradiation radical weathering test method, a light irradiation radical weathering tester was developed.
促進劣化耐候試験において、従来から採用している光、温度、湿度等の劣化因子の他に、新たに酸素などのラジカル化したガスを劣化因子として加えることによって、より自然環境に忠実な再現性を有し、かつ超促進性を有する耐候試験が可能となったことによって、精度よく迅速に試料の耐候性を評価できる。
In accelerated accelerated weathering tests, in addition to conventional degradation factors such as light, temperature, and humidity, new radicalized gases such as oxygen are added as degradation factors, making it more faithful to the natural environment. The weather resistance test having super-acceleration has become possible, so that the weather resistance of the sample can be evaluated with high accuracy and speed.

また、試験槽１０内に試料１１を装着するときは、試験を停止した状態で、図には示していないが試料台昇降装置により、前記試料台５の上部を排気台６の下部より下方に移動させ、試料１１を試料台５に装着する。装着後、試料台昇降装置で試料台５を上昇させ、元の位置に戻す。
実施例１では、光源１にキセノンアークランプを用いた。本試験機の場合は、円筒形のキセノンアークランプの長手方向を水平とし、光源１は、試験槽１０外部の上方に設置する。試料１１表面の放射強度を均一または変化させる場合にはレンズを介して光を照射する。図には示していないが、所定の波長を試料１１に照射するために光源１と試料１１の間に所定のフィルターとレンズを介在させる。
試験時には、高純度酸素をガスボンベ３からガス導入口４を介して試験槽１０に導入し、試験槽１０内の圧力を一定に保ち、電極板９に高周波電力を印加してプラズマを発生させ、酸素ラジカルを生成し、これを試料１１に作用させると同時に、上部に設置した光源１から所定の分光分布を有する光を照射する。
