摘要
ZnO压敏电阻器对所用银浆附着力要求较高，通过对ZnO压敏电阻器用银浆料中玻璃粉的研究，提出了用复合玻璃粉制备ZnO压敏电阻器用银浆料。浆料经不同温度烧成后，测得了烧成膜与基体附着力的数据，复合玻璃粉S2：S5的最佳质量比为1：2．5，复合玻璃粉添加量（质量分数）为3．5％时，可显著提高浆料对基体的附着力。结果表明：可采用适合干480～580℃烧成温度的复合玻璃粉来提高烧成膜的致密性及对基体的附着力。并对其机理进行了探讨。
Studied were an actions of glass powders which was single or composite in silver paste for ZnO based varistor. The optimal ratio of composite glass powder （S2：S5） was 1：2.5 （mass ratio）. Additive amount of composite glass powder in silver paste was 3.5% （mass fraction）. Obtained results show that the sintered films are close-knit and strong when sintering temperature of silver paste is 480～580℃.
