摘　　要：研制了一种室温固化的可转移有机硅压敏胶 ,该胶与炸药 PBX- 1、PBX- 2、铝块的剥离强度分别为 5 .0 4 N/ 2 5 mm、3.0 7N/ 2 5mm、17N/ 2 5 mm,与三种炸药 PBX- 1、PBX- 2、JB90 14的相容性满足军标要求 ,该胶转移至硅橡胶泡沫垫层上后 ,在 6 0℃下加压粘贴于铝块上保持 4 8h后剥离 。In this paper, a transfer silicone pressure sensitive adhesive (PSA) cured at room temperature was intrudoced. Peel strength of PSA from PBX 1, PBX 2 and aluminium was 5.04 N/25 mm,3.07 N/25 mm and 17 N/25 mm respectively. Compatibility of the PSA with PBX 1, PBX 2 meet the malitary standard. The PSA was transfered to silixane rubber foam cushion, subsequently bonded to aluminium at 60 ℃ for 48 h, the surface of aluminium hadn't residual of PSA after debonding.
