Description

一种抗菌不锈钢厨刀的制备方法
技术领域
本发明涉及厨刀技术领域，特别涉及一种抗菌不锈钢厨刀的制备方法。
背景技术
不锈钢厨刀具有耐蚀性、良好加工性等特点，并且韧性好，使用时不易崩刃，是目前的主流家庭用厨刀。随着消费者对食品安全关注度的提高，市场对不锈钢厨刀的自洁性能的要求也越来越高。不锈钢厨刀的自洁性能主要体现在抗菌、不沾、易清洗等方面。纳米二氧化钛（TiO2），由于亲水性与光催化性的协同作用，充分发挥抗菌、降解有机污染物、自净化功能，在不锈钢厨刀领域具有广阔的应用前景，已成为相关业者的研究重点。
现有技术中出现了一些利用物理气相沉积（PVD）在不锈钢厨刀表面形成二氧化钛（TiO2）光触媒层的技术，如中国专利申请《一种食材料理刀具及刀具硬质薄膜的成型方法》（公布号为CN108546916A，公布日2018年09月18日），该技术提供了一种采用电子束蒸镀法在不锈钢食材料理刀具表面形成TiO2光触媒层，使食材料理刀具具备抗菌、除臭、空气净化、防霉除污的性能。
然而，不锈钢厨刀在切、剥、砍等使用过程中容易钝化，锋利度下降，长期使用需要磨制刀锋，在磨制刀锋的过程中容易把刀锋处的镀层磨掉，磨掉部分就达不到抗菌、不沾、易清洗等效果。为了解决这一问题，中国专利申请《利用物理气相沉积技术制造表面抗菌制品的方法》（公开号为CN1995442A，公开日2007年7月11日），提出在镀膜前需将不锈钢刀进行前处理，具体为将含银或铜不锈钢板焊接或粘贴在刀具主体钢板刀刃处，然后磨制刀锋，再进行物理气相沉积镀制耐磨抗菌表层，由于铜、银具有抗菌效果，即使刀刃磨制后仍然具有抗菌性。
采用上述焊接或粘贴将刀刃和刀具主体结合的技术，需要分别对刀刃和刀具主体完成加工后，再将两者进行焊接或粘贴组装，工序繁琐，技术难度大，效率低下，并且焊接或粘贴的结合方式，结合力差，在厨刀的使用过程中容易发生脱落，存在安全隐患。
发明内容
本发明的目的在于，提供一种抗菌不锈钢厨刀的制备方法，工艺简单，生产效率高，制备得到的不锈钢厨刀抗菌性能持久。
本发明为实现上述目的所采用的技术方案是：
步骤S1.打磨处理：将不锈钢厨刀表面打磨至粗糙度小于Ra0.080；
步骤S2.超声波清洗处理：将步骤S1打磨后的不锈钢厨刀放入超声波清洗池中进行清洗；
步骤S3.化学镀银处理：将步骤S2清洗后的不锈钢厨刀放入烘箱中烘干，将烘干后的不锈钢厨刀放入镀槽中进行化学镀银；
步骤S4.等离子渗银预处理：将步骤S3得到的不锈钢厨刀清洗烘干，烘干后放入真空等离子镀膜装置中，抽真空至4.0×10-3Pa，控制温度为650-750℃，设置电压为1.2kV-1.3kV，电流为3-5A，打开氩气管道阀门充入氩气，控制气体流量为20-40mL/min，利用氩气轰击不锈钢厨刀表面，轰击3-5h后，关闭电源，停止加热；
步骤S5.等离子镀膜处理：当步骤S4中的真空等离子镀膜装置的温度下降到150-200℃时，设置电压为100-120V，电流为30-50A，打开氧气管道阀门充入氧气，氧气流量控制为70-90mL/min，开启钛靶源，镀膜3-5min后，关闭电源，完成镀膜。
采用上述技术方案，通过化学镀银在不锈钢厨刀表面形成银层，并利用等离子渗银预处理使得化学镀银层向基体内部扩散。氩气在真空等离子镀膜装置的阴、阳极间被电离产生Ar+等离子体，Ar+等离子体在电场的作用下，将向阴极运动，对不锈钢厨刀表面的银层进行轰击，利用轰击产生的反冲和增强扩散效应使银向基体内部渗透。即使在长期使用的过程中，磨制刀刃导致表层镀膜磨损，由于在基体中存在抗菌性银元素，不锈钢厨刀仍然具有抗菌性能。同时，避免了需要通过焊接或粘接的方式将含银刀刃和刀具主体结合而导致工艺繁琐，结合不牢固易脱落的问题。此外，本发明仅需在等离子镀膜处理前，利用常规的工作气体氩气进行轰击预处理，工艺简单，方便批量操作，提高生产效率。
进一步地，所述步骤S3中，化学镀银的镀液配方为：15g/L硝酸银，10mL/L乙醇，15g/L酒石酸钾钠，镀液的PH值为12.5。
进一步地，所述步骤S3中，化学镀银的温度为10-20℃，施镀时间为1-1.5h。
采用上述技术方案，在不锈钢厨刀表表面制备得到的镀银层均匀致密，孔隙少，晶粒细小，镀银层与基材结合强度高。镀银层与基体的结合力对后续的银扩散有重要影响，结合紧密，银扩散进入基体的位能低，容易扩散进入基体。采用化学镀银的工艺，操作简单，成本低廉，厚度可控，解决了采用物理气相沉积技术需要使用银靶，而导致成本过高的问题。
进一步地，所述步骤S2中，超声清洗的试剂为乙醇或丙酮。
进一步地，所述步骤S2中，超声清洗的频率为20-30KHz，温度为30℃-40℃，清洗20-30min。
采用上述技术方案，能够有效清除不锈钢厨刀表面的油污及附着物，方便后续化学镀银，提高银层与基材的结合强度。
进一步地，所述步骤S3中，不锈钢厨刀的烘干温度为150-170℃，时间为30-40min。
采用上述技术方案，能够快速烘干不锈钢厨刀，提高工作效率。
综上所述，本发明具有以下有益效果：
1、采用本发明提供的制备方法得到的不锈钢厨刀，在其表面形成有TiO2光触媒层，具有抗菌、不沾、易清洗的特性，此外，不锈钢厨刀基体内部还存在抗菌性元素Ag，即使在长久的使用过程中导致表面TiO2光触媒层部分磨损，仍然能够保证不锈钢厨刀的持久的抗菌性；
2、本发明提供的制备方法，常规的TiO2等离子镀膜处理前都会进行氩离子轰击预处理，本发明利用氩离子轰击预处理，对化学镀银层进行轰击，使得化学镀银层中的银向基体内部渗透，与后续的TiO2等离子镀膜工艺有机结合，缩短工艺流程，减少能源消耗，操作方便，有效提高生产效率；
3、本发明提供的制备方法，镀银层采用化学镀银的工艺，操作简单，成本低廉，厚度可控，避免了采用物理气相沉积镀银需要使用价格昂贵的银靶，降低成本。

抗菌性测试
步骤1.将实施例1-3的不锈钢厨刀试样和对比例的不锈钢厨刀试样在MM-200型磨损试验机上进行磨损试验，采用“磨环-试样”相对滑动对磨方式，试样不动，通过对磨环的旋转实现相对滑动。磨环的材料为GCr15钢，硬度为61HRC。采用干磨方式，磨损时间为1h、3h，使用载荷100N，环线速度为0.4m/s。

用含75％乙醇的脱脂棉对试样进行灭菌处理。
取浓度为5×105个/mL的大肠杆菌菌液0.1 mL滴在已制备好的试样表面，用无菌聚乙烯膜平铺覆盖于试样表面，使菌液均匀贴覆在试样表面上。
把试样置于温度35℃、相对湿度ＲH＞90% 的细菌培养箱中培养4 h。
用6mL氯化钠溶液冲洗试样与聚乙烯膜表面，取0.1mL冲洗液均布于平板培养基上。把平板平放，置于试验台上20～30 min，使菌液深入到培养基表层内。
将平板倒置于恒温培养箱中培养24 h，取出平板，在菌落计数器上读取菌落个数，计算抗菌率 K。每个试样均重复3次，取平均值。抗菌性能用灭菌率来评价，灭菌率用下式计算：
K% = ( NC－NS) /NC×100%，NC为空白对照样（无菌聚乙烯膜）上活菌的个数；NS为试样上活菌的个数。
表1为试样抗菌性能结果。
试样 24h后活菌数（cfu/ml） 灭菌率（%）
空白 ＞5.0×10<sup>5</sup> 0
实施例1磨损前 ＜10 100%
实施例2磨损前 ＜10 100%
实施例3磨损前 ＜10 100%
对比例磨损前 ＜10 100%
实施例1磨损1h ＜10 100%
实施例2磨损1h ＜10 100%
实施例3磨损1h ＜10 100%
对比例磨损1h 5.0×10<sup>4</sup> 90%
实施例1磨损3h ＜10 100%
实施例2磨损3h ＜10 100%
实施例3磨损3h ＜10 100%
对比例磨损3h 2.5×10<sup>5</sup> 50%
从表中结果来看，实施例1-3和对比例的试样在磨损试验前对大肠杆菌均具有较强的抗菌效果。经过磨损1h后，实施例1-3的试样仍然具有较强的抗菌效果，对比例的试样的抗菌效果下降，抗菌效果表现为良好，经过磨损3h后，实施例1-3的试样仍然具有较强的抗菌效果，对比例的试样的抗菌效果进一步下降。
尽管上述实施例对本发明做出了详尽的描述，但它仅仅是本发明一部分实施例，而不是全部实施例，人们还可以根据本实施例在不经创造性前提下获得其他实施例，这些实施例都属于本发明保护范围。
