Description

一种五金件表面处理工艺
技术领域
本发明属于五金件制备技术领域，更具体地说，尤其涉及一种五金件表面处理工艺。
背景技术
对五金件进行防护不但可减少经济损失，还可节约原材料，避免资源的浪费。五金件材料的保护方法主要有涂刷外涂层、电化学保护、电镀、化学镀等多种方法，有机涂层被认为是最有效最直接的五金件防腐的方法，常用的有机防腐涂料有环氧树脂涂料、聚氨酯涂料、无机富锌涂料、高固体分涂料等，其涂敷工艺简单，往往可直接涂敷在五金件表面，经固化后获得致密的有机膜，有机膜能够隔绝腐蚀介质，阻止其对金属的侵蚀而保护五金件。
然而由于有机涂料与五金件基材分属于两类性质完全不同的材料，有机涂料在五金件表面涂覆后仍有不少空隙，不但会减弱涂层对金属间的附着力，而且也削弱了对腐蚀性介质的阻档作用。另外，很多防腐蚀涂料，尽管其有优良的黏结性能、防腐性能和机械性能等，因分子中含有一些亲水性基团，容易从环境中吸收水，因而表现出亲水性，导致对金属防护性能的降低。因此有必要对有机涂料进行改性，减少其吸水性能、增强其与基底材料的附着性能，有望达到更好的防腐效果。
发明内容
本发明的目的在于提供一种五金件表面处理工艺，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种五金件表面处理工艺，包括如下步骤：
S1、机械处理：通过磨光轮对金属基体表面的划伤、毛刺、气孔、腐蚀斑点等进行磨光处理，得到磨光处理后的金属基体；
S2、除油以及除锈处理：将金属基材浸于有机溶剂中，浸泡后的金属基材采用浸透有机溶剂棉纱对基材表面进行除油，接着对除油后的金属基材表面采用喷砂处理技术借助于压缩空气的压力，将干石英砂喷洒到金属基材的表面，对磨光处理后金属基材的表面没有剔除掉的毛刺、锈蚀、附着油类物质以及氧化皮层等进行剔除，制得带有粗糙砂面的金属基材；
S3、金属基材清洗干燥：将步骤S2中带有粗糙砂面的金属基材置于无水酒精中进行超声清洗，超声清洗后对金属基材进行两遍淋洗工艺，最后进行干燥后备用；
S4、渗氮处理：将干燥后的金属基材采用真空镀膜法金属基材表面镀一层氮化钛铝硅薄膜，然后采用弧光离子渗氮法对镀膜表面进行离子渗氮处理；
S5、涂覆防腐涂层：对经过渗氮处理后的金属基材表面涂覆石墨烯水性复合防腐涂层，最后喷涂氨基烘漆。
优选的，所述步骤S2中喷洒的石英砂为80-120目。
优选的，所述步骤S4中真空镀膜法为磁控溅射法，所述真空镀膜的氮化钛铝硅薄膜的厚度小于45-55μm。
优选的，所述步骤S4中渗氮处理的渗氮温度为450-650℃，且处理时间为0.5-15h。
优选的，所述步骤S5中石墨烯水性复合防腐涂层制备方法为向有机硅氧烷改性树脂溶液中加入超声后的石墨烯-聚吡咯水分散液以及缓蚀剂。
与现有技术相比，本发明的有益效果是：本发明采用有机硅氧烷改性树脂溶液与超声后的石墨烯-聚吡咯水分散液混合制得防腐涂料，有机硅烷分子可作为偶联剂掺杂到有机涂料中对涂料进行改性，增强有机涂料对金属基材的附着力，从而大大提高其防护性能，掺杂后有机涂层的机械性能、疏水性能、阻水性能都有所提高，而且石墨烯的加入提高了涂料的防腐性能，使得涂料具有优异的水分散稳定性能，在涂覆防腐涂层之前对金属基材进行先镀膜再渗氮处理的工艺，使得制得的五金件耐磨性好，表面硬度高，而且质量稳定可靠。
