【摘要】 以球形银粉、无铅玻璃粉和有机载体为原料制备汽车后挡风玻璃加热线用银浆。通过不同的烧结工艺，利用SEM观察烧结银膜的形貌，测试烧结膜的方阻及附着力，讨论烧结温度、保温时间对银膜性能的影响。结果表明，烧结温度640℃时，能获得性能较好的银膜，银膜附着力为9N，银膜方阻为20 m?/；保温时间7 min时，能获性能较好的银膜，银膜附着力为9.6 N，银膜方阻为17.2 m?/。更多还原

【Abstract】 Silver paste for auto rear glass hot wires was prepared with the mixture of spherical silver powder, lead-free glass frit and organic vehicle. With different sintering process, the effects of sintering tempertature and sintering time on properties of Ag film were discussed by observing the morphology of the sintered Ag film with SEM and measuring the resistivity and adhesion. The results show that silver film with good performance can be obtained with the sintering temperature at 640℃, silver film adhesion for 9 N, silver film resistivity for 20 m?/□;silver film with good performance can be obtained with the sintering time at 7 min, silver film adhesion for 9.6 N, silver film resistivity for 17.2m?/□.更多还原
