Revivification of the Polysulfide Sealant

选用 Ｅ－ ４４ 环氧树脂作为增粘剂，对剥离强度不合格的 Ｊ Ｌ Ｃ－ ２２ 聚硫密封胶进行再生改性。试验结果表明，再生后 Ｊ Ｌ Ｃ－ ２２ 密封胶的剥离强度由原来的０２ ｋ Ｎ·ｍ １ 提高到１９ ｋ Ｎ·ｍ１ 。

Revivification method of losing efficacy JLC-22 sealant by adding epoxy resin were studied.The results show that peel strength of revival sealant has increased from 0.2 kN·m -1 to 1.9 kN·m -1
