复合聚合物导体浆料的制备研究

摘要

选用自制银包铜粉(含银60％)作为导电相,聚酯与聚丙烯酸酯(1∶1)组成有机载体,制备导电相含量为60％聚合物复合导体浆料,其性能指标达到银含量为50％银浆的性能指标.该复合导体浆料与相同性能银浆对比,节约银14％,实现了银包铜粉最优化使用和导电浆料成本的最低化,经济效益十分可观.%The homemade silver-coated copper powder (silver content is 60％) as the conductive phase,polyester and polyacrylate (1∶1) composes the organic carrier to prepare the composite polymer conductive paste that the conductive phase content is 60％,which performance indicators can reach to the performance indicators of silver paste with 50％ silver content.Comparison between the compound conductive paste and the silver paste with the same performance,saving of 14％ silver,so the optimization of silver-coated copper powder usage and the minimization of cost can be realized,the economic benefit is very considerable.
