Description
技术领域
本发明涉及不锈钢带技术领域,具体为一种电子器件用超薄不锈钢带及其制备方法。
背景技术
近年来,超薄不锈钢带是将不锈钢带经过辊压机多次轧制,得到的厚度≤0.3mm的带材;现有工艺中,通常采用热轧或冷轧进行轧制;相较于热轧过程中在变形、稳定性、抗疲劳等方面效果较差,轧制过程不稳定,薄度受限等问题。冷轧不锈钢带具有成型速度快、涂层损伤低等优点,可以制备超薄不锈钢带。
现有冷轧超薄不锈钢带中,存在机械性能不稳定、表面粗糙度不均匀等问题,轧制过程中易产生氢脆,影响产品质量,降低良品率。另一方面,超薄不锈钢带表面硬度低,耐磨性、耐腐蚀性不佳。如果通过表面涂层化,会使得不锈钢带厚度增加,影响其应用范围。
综上,解决上述问题,制备一种电子器件用超薄不锈钢带及其制备方法。
发明内容
本发明的目的在于提供一种电子器件用超薄不锈钢带及其制备方法,以解决上述背景技术中提出的问题。
为了解决上述技术问题,本发明提供如下技术方案:
一种电子器件用超薄不锈钢带的制备方法,包括以下步骤:
步骤1:将3±0.2mm的不锈钢带置于二十辊轧机中,在轧制剂A的辅助下进行一次冷轧,得到厚度为1±0.2mm的不锈钢带A;
步骤2:将不锈钢带A进行一次退火、二次退火、酸洗,得到不锈钢带B;

步骤4:将不锈钢C进行表面渗氮、电解抛光,得到不锈钢带D;
步骤5:将不锈钢带D进行淬火、三次退火,得到不锈钢带E;
步骤6:将不锈钢带E置于平整机中,平整,得到超薄不锈钢带。
较为优化地,步骤1中,一次冷轧过程中,轧制剂A的喷射速度为300~360L/min,温度为40~50℃;轧制力为4000~4500KN,轧制张力为200~300KN,轧制速率为350~450m/min;步骤3中,二次冷轧过程中,轧制剂B的喷射速度为260~300L/min,温度为30~40℃;轧制力为3000~3500KN,轧制张力为100~200KN,轧制速率为250~300m/min。
较为优化地,所述轧制剂A的原料包括以下组分:按重量计,50~60份5号白油、20~30份棕榈油、5~8份1-辛基-3-甲基咪唑六氟磷酸盐、5~10份月桂醇聚氧乙烯醚、5~10份茶多酚棕榈酸酯、5~6份复合二硫化钼。
较为优化地,所述轧制剂B的原料包括以下组分:按重量分数计,1~1.5份复合二硫化钼、0.5~1份二氧化硅、3~5份离子液体、2~3份甘油、92~94份去离子水。
较为优化地,所述二硫化钼复合物的制备方法为:将二硫化钼分散在去离子水中,加入硝酸铈、硝酸镍搅拌均匀,加入氨水调节pH=10.8~11.2,搅拌均匀,得到混合液;将混合液在180~200℃水热反应12小时,洗涤干燥;在氮气氛围下,设置温度为200~300℃煅烧2~3小时,得到复合二硫化钼;所述离子液体的制备方法为:将乙醇胺与琥珀酸依次加入反应瓶中,混合均匀;氮气氛围下,设置微波功率为300W,反应温度为60~65℃,反应30~35分钟;洗涤干燥,得到离子液体。
较为优化地,步骤2中,一次退火过程中,气氛氛围为含氧量为5%的氧气-氮气混合气,温度为1050~1150℃,退火速度70~80m/min;二次退火过程中,气体氛围为氢气含量为5%的氢气-氮气混合气,温度为700~800℃,退火时间为4~6分钟。
较为优化地,酸洗过程中,在电解液为180~200g/L的亚硫酸钠、20~40g/L的抗坏血酸的混合溶液中,设置温度为70~80℃,电压为35V处理5~7分钟,转移至含有45~55g/L的硫酸、20~25g/L的氢氟酸、10~15g/L柠檬酸的混酸溶液中,设置温度为55~65℃处理5~8分钟。
较为优化地,步骤4中,表面渗氮过程中,气体氛围为氨气,温度为400~600℃,渗氮时间为6~8小时;电解抛光过程为:5~6wt%硫酸铵水溶液中,设置温度为75~80℃,电压为200~250V抛光1~2分钟。
较为优化地,步骤5中,淬火过程中,在磁场强度为5~10T下,以液氮为淬火介质冷却4~6分钟;三次退火过程中,气体氛围为氮气,流量为120~160L/min,温度为1000~1200℃,退火速度70~80m/min;步骤6中,平整过程中,轧制力为1500~2000KN,轧制速率为150~200m/min,延伸率为1~2%。
较为优化地,一种电子器件用超薄不锈钢带的制备方法制备得到的超薄不锈钢带。
本技术方案中,通过在一次冷轧过程中使用油系轧制剂,在二次冷轧过程使用水系轧制剂;协同增强冷轧后不锈钢带的机械稳定性;同时通过冷轧、酸洗、抛光等多个步骤的协同,均匀化表面粗糙度。通过渗氮处理强化表面强度,增加耐磨性和耐腐蚀性。从而有效提高超薄不锈钢带的质量和良品率。
(1)方案中使用轧制剂A(油系轧制剂)、轧制剂B(水系轧制)辅助两次轧制过程,形成良好的润滑膜,有效抑制不锈钢带轧制过程中的机械不稳定性和氢脆现象。其中轧制A相较于轧制剂B粘度更高,因此,油系轧制剂A一次冷轧后表面粗糙度较高,约为0.5~0.6μm;然后通过低粘度的水系轧制剂B二次冷轧后,表面粗糙度降至0.06~0.08μm;两者协同,在保持机械稳定性的前提下,使得不锈钢带具有良好粗糙度表面。同时,两种抑制剂的辅助协同,有效降低了轧制力,降低了能耗。
其中,两种轧制剂中均含有二硫化钼复合物作为减膜剂,相较于直接使用二硫化钼,表面负载有氧化铈氧化镍纳米粒子的复合物,不仅利于片层二硫化钼和粒子氧化铈、氧化镍的分散性,同时,两者间存在界面相互作用(滑动摩擦),更有助于减磨,抑制微裂纹产生。同时,冷轧退火后残留在表面的二硫化钼复合物可以有效存在渗氮过程(二硫化钼复合物具有催化作用,可以氨气分解,从而促进渗氮)。
其中,轧制剂B中,为了在不增加甘油含量的基础增加一定粘度,使得轧制剂B可以在钢界面形成良好的润滑膜,因此在其中另外加入了二氧化硅和离子液体(离子液体是由二乙醇胺和琥珀酸制备得到的,既可以有效分散无机粒子、增加粘度,又可以增加防腐性能),协同有效减磨的基础上,抑制水系轧制剂的腐蚀性,抑制氢脆,从而保证不锈钢带的力学性能。
(2)方案中,通过在一次轧制后一次退火后进行二次退火有效除去表面碳,抑制碳腐蚀,抑制氢脆。
利用退火后表面残留的无机颗粒(硫化钼复合物和二氧化硅)促进表面渗氮,形成耐磨性好、耐腐蚀性佳的表面。并在气体氛围下表面渗碳后,使用电解抛光,进一步表面钝化,降低表面粗糙度至0.02±0.01μm左右。同时,电解抛光中使用的是的硫酸铵溶液,可以作为氮源,促进渗氮层厚度,提高表面性能。另一方面,由于最终需要平整化,表面渗氮后,表面硬度增加,易使得平整化过程中产生微裂纹,从而降低超薄不锈钢带的耐腐蚀性和机械性能,降低成品率。因此方案中,使用磁性淬火,使得表面渗氮层具有一定韧性,从而抑制平整化过程中的缺陷。
综上,通过多步协同工艺过程,提高超薄不锈钢带冷轧过程中机械稳定性、粗糙度均匀化,以及增加表面耐腐蚀性和耐磨性。

实验:将实施例和对比例中制备得到的超薄不锈钢带进行相关性能检测。参照标准方法GB/T228.1进行力学性能测试;参照GB/T4239进行硬度测试,载荷为200g;参照ASTM-B117-2011盐雾实验,5wt%氯化钠溶液,温度为35℃,试验时间为720小时;计算得到腐蚀率。
实施例 | 屈服强度MPa | 硬度HV | 腐蚀率g/cm2.h |
实施例1 | 371 | 168 | 0.196 |
实施例2 | 366 | 164 | 0.201 |
实施例3 | 362 | 163 | 0.204 |
对比例1 | 340 | 149 | 0.321 |
对比例2 | 344 | 152 | 0.367 |
对比例3 | 351 | 159 | 0.213 |
对比例4 | 358 | 154 | 0.301 |
对比例5 | 360 | 163 | 0.340 |
对比例6 | 354 | 160 | 0.207 |
对比例7 | 362 | 165 | 0.512 |
结论:由实施例1~3中的数据表明:所制备得到的超薄不锈钢带具有优异的力学性能,良好的表面硬度和优异的耐腐蚀性。对比例1~ 2的数据表明:单一使用一种轧制剂使得性能下降,两种轧制剂之间存在协同作用。对比例3~4中表明:离子液体形成了更好的耐腐蚀的界面膜层,有效提高了钢带机械性能的稳定性;复合二硫化钼相较于二硫化钼具有更好的减磨性和分散性,促使形成了更好的界面膜层,利于冷轧。对比例5表明:不进行二次退火,使得酸洗过程后存在碳腐蚀性,降低了超薄不锈钢带的性能。对比例6中,由于未进行电解抛光,使得渗氮层性能降低,从而使得耐腐蚀性和硬度降低。对比例7中,由于未进行淬火过程,使得平整过程中存在微裂纹,使得耐腐蚀性能下降。
最后应说明的是:以上所述仅为本发明的优选实施例而已,并不用于限制本发明,尽管参照前述实施例对本发明进行了详细的说明,对于本领域的技术人员来说,其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
