Description

一种箍筋表面防护工艺
技术领域
本发明涉及金属防护技术领域，尤其涉及一种箍筋表面防护工艺。
背景技术
随着金属制品在工业和生活中的广泛应用，相应的金属腐蚀也日趋严重，因此各种防腐技术也在金属加工方面被广泛应用，其中金属表面涂层防护技术应用最为广泛，最有效。
目前喷漆、喷粉或电泳前处理是根据器件板材不同多采用磷化以及铬钝化处理。但这两种处理方法均存在较大缺陷。在环保方面:磷化含锌、锰、镍等重金属离子并且含有大量的磷化渣，铬钝化处理本身就含有严重毒性的铬离子，已与国家规定的环保要求相背离。在使用成本方面:磷化处理过程中会产生大量磷化渣，因此在磷化工艺过程中需要一套除渣装置与之配套;并且磷化使用温度大多为30-500C，因此还需要辅助加热设备及热源对磷化槽进行加热;这些都导致磷化的成本较高。因此从环保性和使用成本方面考虑，寻找一种新型的环保、节能、低排放、低使用成本的表面处理技术成为国内外广大业内技术人员研究的重点。
发明内容
本发明的目的是为了解决现有技术中存在的缺点，而提出的一种箍筋表面防护工艺。
为了实现上述目的，本发明采用了如下技术方案：
一种箍筋表面防护工艺，具体包括以下步骤：
S1、将箍筋表面先通过盐酸溶液清洗；
S2、酸洗后的金属工件用金相砂纸打磨光滑，然后将金属工件表面预脱脂；
S3、依照从前到后的顺序，先600C下脱脂液超声清洗20min、去离子水冲洗干净、混合碱洗液600C超声清洗5min、去离子水冲洗干净、最后混合碱洗液600C超声清洗5min；
S4、去离子水冲洗干净后，再在硅烷溶液中浸渍10-30min；
S5、烘干：在型号为JB-520的烘干箱内烘干，烘干温度为100-1300C,时间为15-22min；
S6、分析检测：将S5中的表面处理后的成品进行检测。
优选的，所述硅烷溶液包括硅烷A和硅烷B，所述硅烷A和硅烷B的比为5/1，混合硅烷浓度为5%。
优选的，所述硅烷溶液内包括成本较低、较环保且可以提高膜耐腐蚀性能的绿色缓蚀剂硝酸镧作为添加剂，硝酸镧的浓度为0.1-0.4g/L，硝酸镧不会影响溶液稳定性，能够增强硅烷膜的耐腐蚀。
优选的，所述硝酸镧的最佳浓度为0.3g/L。
