Description
技术领域technical field
本发明具体涉及一种碱性锌镍合金电镀液，同时还涉及一种碱性锌镍合金电镀液的制备方法和应用，属于电镀技术领域。The invention specifically relates to an alkaline zinc-nickel alloy electroplating solution, and also relates to a preparation method and application of an alkaline zinc-nickel alloy electroplating solution, belonging to the technical field of electroplating.
背景技术Background technique
锌镍合金镀层是一种新型优良的防护性镀层，主要应用于航空航天、汽车工业和机械电子产品中。在电气领域零部件表面防腐及防护中，锌镍合金膜层作为最终的防护膜层，要求其具备优良的耐蚀性、耐磨性及硬度等。Zinc-nickel alloy coating is a new type of excellent protective coating, which is mainly used in aerospace, automobile industry and mechanical and electronic products. In the anticorrosion and protection of parts in the electrical field, the zinc-nickel alloy film layer is used as the final protective film layer, which is required to have excellent corrosion resistance, wear resistance and hardness.
目前，锌镍合金电镀技术在国外已经投入实际应用，而国内生产线上的锌镍合金电镀液主要依靠国外进口。由于锌镍合金膜层的工业领域在近些年来得到拓展，使其成为防腐、装饰等不可缺少的重要工艺技术，因此，研究一种碱性锌镍合金电镀液及其制备方法显得尤为重要，特别是对于增加中高压开关产品轴类零部件等的耐蚀能力有着重要的意义。At present, zinc-nickel alloy electroplating technology has been put into practical application abroad, while the zinc-nickel alloy electroplating solution on the domestic production line mainly relies on foreign imports. Because the industrial field of the zinc-nickel alloy coating has been expanded in recent years, it has become an indispensable important process technology such as anti-corrosion and decoration. Therefore, it is particularly important to study a kind of alkaline zinc-nickel alloy electroplating solution and its preparation method. In particular, it is of great significance to increase the corrosion resistance of shaft parts of medium and high voltage switch products.
中国专利（公告号：CN 101240437 B）公开了一种电镀液配方，每升电镀液中含有以下组分：氧化锌10～30g，硫酸镍5～13g，氢氧化钠100～140g，络合剂为柠檬酸铵5～40g、三乙醇胺38～80ml、乙二胺25～40ml、二乙烯三胺3～20ml、四乙烯五胺3ml以上、酒石酸钾钠15～25g、EDTA8～15g、氨水10～20ml中的两种或多种，添加剂为环氧氯丙烷与胺类的反应产物1.5～15ml以及植酸0.05～15ml、植酸钠0.1～5g、CTAB0.1～5g中的任意一种，光亮剂为ZB1～10ml、香兰素0.2～2g、硫脲1～2g、糖精1～5g中的一种或多种，余量为水。然而，上述方法中使用的添加剂和光亮剂较为单一，难以满足镀层综合性能的要求，比如其电镀效率低，20min只有6μm，膜层较薄，很难达到较高的耐蚀性，另外没有镀层硬度的性能参数，无法适用于高压电器轴类零件的耐磨性要求。Chinese patent (notification number: CN 101240437 B) discloses a formula of electroplating solution, each liter of electroplating solution contains the following components: zinc oxide 10-30g, nickel sulfate 5-13g, sodium hydroxide 100-140g, complexing agent Ammonium citrate 5~40g, triethanolamine 38~80ml, ethylenediamine 25~40ml, diethylenetriamine 3~20ml, tetraethylenepentamine 3ml or more, potassium sodium tartrate 15~25g, EDTA8~15g, ammonia water 10~ Two or more in 20ml, the additive is 1.5-15ml of the reaction product of epichlorohydrin and amines, 0.05-15ml of phytic acid, 0.1-5g of sodium phytate, 0.1-5g of CTAB, bright The agent is one or more of ZB 1-10ml, vanillin 0.2-2g, thiourea 1-2g, saccharin 1-5g, and the balance is water. However, the additives and brighteners used in the above method are relatively single, and it is difficult to meet the requirements of the comprehensive performance of the coating. For example, the electroplating efficiency is low, only 6 μm in 20 minutes, and the film is thin, so it is difficult to achieve high corrosion resistance. In addition, there is no coating The performance parameters of hardness cannot be applied to the wear resistance requirements of shaft parts of high-voltage electrical appliances.
