Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、試験法に関し、特に、エポキシ樹脂と物質と
の密着性確認試験に関する。TECHNICAL FIELD The present invention relates to a test method, and more particularly to a test for confirming adhesion between an epoxy resin and a substance.

〔従来の技術〕[Conventional technology]

従来、この種の密着性確認試験としては、エポキシ樹脂

験、ラジオグラフィ気密性試験と呼ばれている。Conventionally, as this type of adhesion confirmation test, a pull-out test in which a substance whose one end is sealed with epoxy resin is pulled, and a test sample is placed in a "fluorescent solution", "red ink", "radioactive element atmosphere" There is a test in which they are stored for a time, and then grinding or cross-section cutting is performed to observe the degree of penetration of these liquids or elements. They are generally called a fluorescence immersion test, a red check test, and a radiographic airtightness test, respectively.

ければならず経費と手間が必要という欠点がある。In the pull-out test described above, it is difficult to evaluate only the adhesiveness due to the effects of the resin hardness, the shape of the substance, etc., in addition to the resin adhesiveness. Further, in the fluorescent immersion test and the red check test, it is not possible to immediately judge the superiority or inferiority because it is necessary to immerse the samples for a long time when comparing the samples having good adhesion. In addition, the radiographic airtightness test has a drawback in that it is necessary to prepare a facility where safety is ensured for handling radioactive elements or to entrust it to a contractor, which requires expense and labor.

Store in the high temperature bath 4 at ℃ (b). At this time, if the adhesiveness between the epoxy resin 1 and the substance 2 is poor, the epoxy resin 1 near the interface 5 comes into contact with the high temperature atmosphere and a chemical change occurs. Next, after storage, the sample 3 to be tested is cut at a cross section or ground to form an interface 5.
(C). Finally, with the fluorescence microscope 6, the interface 5
The vicinity is observed (d), and the quality of the adhesiveness is judged by the presence or absence of the fluorescent coloring area 7 (e).

After the sample 3 to be tested is prepared (a), it is put into the temperature cycle test tank 8 (b). Then, the sample is processed and tested in the same procedure as in Example 1 (c) to (d). According to this embodiment, there is an advantage that the adhesiveness of the interface 5 is rapidly decreased and high-temperature storage is performed at a high temperature of the temperature cycle, and the adhesiveness can be evaluated in a short period of time.
