摘　　要：具有层次挥发性和良好的触变性的有机载体影响银导电浆料的印刷性和烧结性。实验采用丝网印刷工艺，在松油醇-丁基卡必醇-乙基纤维素体系中添加松节油、1,4-丁内酯、甘油、邻苯二甲酸二丁酯四种有机物调节有机载体的挥发性，另外探究在有机载体中添加氢化蓖麻油、聚酰胺蜡对有机载体的触变性的影响。发现，当松节油=10%、1，4-丁内酯=15%0、松油醇=35%、丁基卡必醇=10%、丙三醇=10%、邻苯二甲酸二丁酯=10%时溶剂具有良好的挥发性，挥发均匀，避免了集中挥发造成银膜气孔的产生。另外，当聚酰胺蜡质量分数为0.4%时，触变指数为1.9，有机载体具有较好的触变性，可有效改善银导电浆料的印刷性。organic carrier with a level of volatile and good thixotropy affect the printing resistance and sintering of conductive silver paste, screen printing was adopted, and turpentine, 1,4-butyl ester, glycerin and phthalic acid dibutyl were added into terpineol-ethyl cellulose-butyl carbitol system to regulate volatile of organic carrier. And the hydrogenated castor oil and polyamide wax were added in the organic carrier to explore the influence on thixotropy of organic carrier.It was found that when thew（turpentine）= 10%,w（1,4-butyrolactone）=15%,w（terpineol）=35%,w（butyl carbitol）=10%,w（glycerin）=10%,w（phthalic acid dibutyl）=10%, the solvent has good volatile. It can avoids the production of pores on silver film caused by concentrated volatile. In addition, when the mass fraction of polyamide wax is 0.4%, the thixotropic index is 1.9, organic carrier has good thixotropy, which can effectively improve the printing quality of silver conductive paste.
