Conductive adhesive film

The invention discloses a pressure-sensitive conductive film with a long validity period, the conductive film comprises a base material 1, a release layer 2 and a conductive adhesive layer 3, and theconductive adhesive layer is composed of organosilicon modified thermoplastic polyamide-imide, phenoxy epoxy resin, low Tg value acrylic resin, fumed silica, conductive metal powder, an antioxidant, aflame retardant, a latent curing agent and a mixed solvent. Compared with the prior art, the pressure-sensitive conductive film has the following advantages: the conductive adhesive layer has strongviscosity, does not need refrigeration storage, can be rapidly processed to the flexible substrate plate, and has excellent adhesion fastness, filling property and storage timeliness. 本发明公开了一种有效期长的压敏型导电膜，所述导电膜包含基材1、离型层2、导电胶层3，所述导电胶层由有机硅改性热塑性聚酰胺亚胺、酚氧型环氧树脂、低Tg值丙烯酸树脂、气相二氧化硅、导电金属粉、抗氧化剂、阻燃剂、潜伏固化剂、混合溶剂组成。本发明具有如下的优点：导电胶层具有较强粘性，不需要冷藏储存，快速加工到柔性基材板上，具有优异的附着牢度、填充性和储存时效性。
