技术领域
本发明涉及金属表面处理技术领域，特别是关于一种铝制品表面处理工艺。
背景技术
随着铝冶炼和加工技术发展，铝制品现已广泛应用于航空，建材、车辆、船舶、轻工等部门。在国外的先进工业化国家如美、英、日本等国，从二十年代开发工业生产铝制品阳极氧化膜算起，近六十年来，铝制品的表面处理技术发展极为迅速。以轻工产品而言，应用自动化设备，严格的工艺氧化出来的产品，经过胶版印刷，热转移印花着色，电泳涂漆等装饰性处理，将使产品给人以十分美观、精致的外观。我国的铝制品工业起步较慢，但发展也很快。从解放初仅有几个小企业到现在已拥有遍布全国一百多个较大企业，年产量超过五万吨。但是随着人民生活水平不断提高，铝制品仍远远不能满足人民生活需求，特别是和国外同类产品相比，在质量和花式品种方面，差距很大，显示了我国铝制品加工和表面处理技术相对落后。近几年，通过频繁的国内外科技交流，以及科技工作者的努力，试验和采用了一些新工艺和新技术，但总的来说，我国铝制品表面处理技术方面尚处于待开发的发展时期。在电子元配件上经常需要用到铝制品并且需要在铝制品外表面喷涂一层铁涂层以满足工业需求，而现有的表面处理工艺成本高，工序繁琐，生产效率低下，对环境污染较大不利于环境保护。
发明内容
有鉴于此，本发明提供一种铝制品表面环保处理工艺，能够解决现有技术上铝制品表面环保处理工艺成本高，工序繁琐，生产效率低下，对环境污染较大不利于环境保护的问题。
本发明的一种铝制品表面环保处理工艺，包括以下步骤：
S1：选用棕刚玉磨料对铝制品表面进行喷砂处理，去除铝制品表面的氧化皮。
S2：选取工业铁并将该工业铁使用电弧喷涂设备对S1处理后的铝制品进行电弧喷涂处理。
S3：使用砂轮对S2处理后的铝制品进行磨砂处理。

S5：采用有机硅对S4处理后的铝制品进行喷涂，喷涂气压2kg/cm2，喷涂距离20cm，环境温度25℃，相对湿度60％。
S6：在温度为280℃环境下对步骤S5处理后的铝制品固化烧结6分钟，即完成加工处理得到成品。
较优的，步骤S1中喷砂处理的气压为6kg/cm2，转盘频率25Hz，距离20cm，时间10S。
较优的，步骤S1喷砂处理后铝制品的外表面粗糙度在2.5μm～5.0μm之间。
较优的，步骤S2中工业铁每份中化学成分质量比为Fe≥98.2％、C≤1.8％。
较优的，步骤S2中电弧喷涂处理的喷涂距离15cm，压力6kg/cm2。
较优的，步骤S3中砂轮选择180#砂轮。
本发明相较于现有技术的有益效果是：
