以下に本発明を実施例により説明するが、本発明はこれらに制限されるものではない。
本発明で、「部」として表わしたものは特に限定しない限り重量部を示す。
表１に示す配合組成及び配合量で樹脂組成物を作製し、その塗膜の特性を下記の方法で測定した。結果を表1に示す。
EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples.
In the present invention, what is expressed as “parts” indicates parts by weight unless otherwise specified.
The resin composition was produced with the compounding composition and compounding quantity shown in Table 1, and the characteristic of the coating film was measured with the following method. The results are shown in Table 1.
(1)基材（ガラス）との接着性
ＪＩＳ Ｋ ５４００の「碁盤目テープ法」に準じ試験を行った。
(2)透湿度
ＪＩＳ Ｚ ０２０８の「防湿包装材料の透湿度試験方法（カップ法）」に準じ試験を行った。
(3)屈曲性
樹脂をブリキ板に塗布後、２５℃／２４ｈの条件で乾燥し、試験片とした。次にこの試験片を１００℃の恒温槽に５００ｈ放置後、ＪＩＳＣ２１０３『丸棒による屈曲性』に準じて屈曲性を測定した。
(1) Adhesiveness with substrate (glass) The test was conducted according to “cross-cut tape method” of JIS K 5400.
(2) Moisture permeability The test was conducted in accordance with JIS Z 0208 “Moisture permeability test method for moisture-proof packaging materials (cup method)”.
(3) Flexibility After applying the resin to the tin plate, it was dried at 25 ° C./24 h to obtain a test piece. Next, this test piece was left in a constant temperature bath at 100 ° C. for 500 hours, and then the flexibility was measured according to JIS C2103 “Bendability with a round bar”.
表１から熱可塑性樹脂を２０重量部、粘着性付与樹脂を１０重量部加えた組成物（実施例１、２）は、基材（ガラス）との接着性および防湿性に優れることがわかる。
また、ＳＥＢＳ樹脂のかわりにＳＢＳ樹脂を使用した組成（比較例１）粘着性付与樹脂を加えなかった組成（比較例２）、熱可塑性樹脂の添加量が少ない組成（比較例３）、シランカップリング剤を添加しなかった組成（比較例４）は、基材（ガラス）との接着性あるいは防湿性あるいは耐熱性に劣ることがわかる。
It can be seen from Table 1 that the compositions (Examples 1 and 2) in which 20 parts by weight of the thermoplastic resin and 10 parts by weight of the tackifying resin are added are excellent in adhesion to the substrate (glass) and moisture resistance.
Also, composition using SBS resin instead of SEBS resin (Comparative Example 1) composition without adding tackifying resin (Comparative Example 2), composition with a small amount of thermoplastic resin added (Comparative Example 3), silane cup It can be seen that the composition in which no ring agent was added (Comparative Example 4) was inferior in adhesion to the substrate (glass), moisture proof or heat resistance.
