Description
技术领域
本发明涉及一种银浆，尤其涉及一种光伏电池用导电银浆。
背景技术
导电浆料作为一种功能性印料因其良好的物理性能在电子信息产品中得到广泛的应用，随着电子产品向更轻、更薄、功能性更强大和更环保的方向发展，对其性能也提出更高的要求。其中低温无卤导电银浆因其优异的导电性、导热性和实用性，广泛应用于薄膜开关、电容电极、触摸屏等方面。低温导电银浆是以导电银粉作为导电填料，与高聚物树脂、溶剂、固化剂、助剂等经搅拌、分散而制成的均匀浆料。导电银浆涂覆在基材上后，在低温环境下烘干(一般低于160℃)，待溶剂释放后，树脂与固化剂逐步反应、固化，最终形成致密的导电膜层。
在电子行业中，为了满足产品的高强度、高机械性能需求，低温导电银浆固化后的导电膜层一般有机械性的要求(膜层硬度、膜层与基材附着力等)。导电银粉为金属粉体，硬度相对较高，但树脂等高聚物的硬度则一般较差。而当以提高银粉填充量方式来满 足高硬度需求时，相对少量的树脂不能充分、有效包覆银粉，导致表层银粉吸附不牢而出现脱落现象。
