Description
技术领域technical field
本实用新型涉及电子银浆制造技术领域，尤其涉及一种银浆过滤系统。The utility model relates to the technical field of electronic silver paste manufacturing, in particular to a silver paste filtering system.
背景技术Background technique
电子银浆由于具有优异的电学性能而被广泛应用于电感器、电容器、太阳能电池及薄膜开关等电子元器件，所以电子银浆成为了太阳能电池表面金属化领域的研究热点。电子银浆通常由银粉、玻璃粉、有机载体和无机添加剂组成，银粉是导电功能相，玻璃粉作为粘接相，无机添加剂充当掺杂相，有机载体则可以控制电极的高宽比。Electronic silver paste is widely used in electronic components such as inductors, capacitors, solar cells and membrane switches due to its excellent electrical properties, so electronic silver paste has become a research hotspot in the field of surface metallization of solar cells. Electronic silver paste is usually composed of silver powder, glass powder, organic vehicle and inorganic additives. Silver powder is the conductive functional phase, glass powder is used as the bonding phase, inorganic additives are used as the doping phase, and the organic vehicle can control the aspect ratio of the electrode.
生产工艺：将超细银粉、玻璃粉、无机添加剂等无机粉体按照一定的质量比充分混合；将松油醇、苯、蓖麻油、乙基纤维素、柠檬酸三丁脂等有机物调制成有机载体；将无机粉体和有机载体充分混合以后，运用三辊研磨机对银浆进行研磨，把银浆研磨到一定细度以后就是所得最终产品。Production process: fully mix ultrafine silver powder, glass powder, inorganic additives and other inorganic powders according to a certain mass ratio; prepare organic substances such as terpineol, benzene, castor oil, ethyl cellulose, and tributyl citrate into organic Carrier: After fully mixing the inorganic powder and the organic carrier, use a three-roll mill to grind the silver paste, and grind the silver paste to a certain fineness to obtain the final product.
在超细银粉制备过程，由于银粉颗粒之间的表面电荷相互作用，会使得银粉产生团聚体，从而形成很多粒径较大的银颗粒；这些团聚体由于在银浆配制过程，还会因为有机载体和银颗粒表面的相互作用再次团聚，所以增大了银浆的细度；并在银浆印刷过程产生虚印、断线等后果。In the preparation process of ultra-fine silver powder, due to the surface charge interaction between the silver powder particles, the silver powder will form agglomerates, thus forming many silver particles with larger particle sizes; these agglomerates will also be caused by organic The interaction between the carrier and the surface of the silver particles is reunited, so the fineness of the silver paste is increased; and there are consequences such as virtual printing and disconnection in the silver paste printing process.
