Description

光亮防腐的环保铝型材制备方法
技术领域
本发明涉及一种型材加工方法，特别设计一种光亮防腐的环保铝型材制备方法。
背景技术
铝型材是一种采用铝制材料，通过轧制、挤出等工艺加工成型的呈几何形状的物体。其在建筑领域中运用广泛。
传统过的铝型材，铝型材的表面经过抗氧化处理后，不仅耐脏，而且表面光滑，易清洁。
为了促使铝型材的表面光亮同时具有防腐性，通常会配置相应的光亮防腐介质对待加工或完成加工的铝型材实施浸泡，传统的光亮防腐介质通常由氟化钠、氟化氢氨、高猛酸钾、锘酸钾、硝酸钠及硫酸镍等成分配比而成。
完成浸泡后，铝型材的表面的光洁度及防腐性得到提高，然而其浸泡介质具有一定的强酸性，促使铝型材表面残留有对环境具有危害的物质，将其用于室内作为窗体时，对人体具有一定的危害。
如若让其表面的有毒物质完全散除，不仅对环境具有危害，而且散除周期长。
发明内容
针对现有技术存在的不足，本发明提供了一种对环境无污染、对人体无危害的光亮防腐的环保铝型材制备方法。
为实现上述目的，本发明提供了如下技术方案：一种光亮防腐的环保铝型材制备方法，其特征在于：a、首先配置光亮防腐液，该光亮防腐液按照重量比如下：氟化钠20-40份、氟化氢铵30-60份、高锰酸钾10-20份、铬酸钾40-50份、磷酸锌15-25份、硝酸钠8-18份、氯化镨5-12份、乙二胺四乙酸10-16份、苹果酸7-14份、十二烷基苯硫酸钠8-12份、硫酸镍6-13份、三乙醇胺15-25份、含有碱金属的还原剂5-10重量份、7-13份重量的氯化聚丙烯或聚烯烃底材附着力促进剂、水500-900份；控制pH值3-4获得光亮防腐液；b、将铝型材投入步骤a中制备的光亮防腐液中浸泡；c、步骤b中光亮防腐液的温度为30℃—40℃；d、将完成浸泡的铝型材烘干处理，烘干温度为50℃—60℃；e、对步骤d中完成烘干的铝型材的表面采用试剂进行碱性处理；f、对步骤e中完成表面化学处理的铝型材表面进行固化处理。
其中，步骤f中的固化处理为在铝型材表面喷涂固化剂，该固化剂为环氧树脂固化剂。
步骤e与步骤f之间还可对铝型材的表面进行碱液化学氧化。
碱性化学氧化通过碱液化学氧化溶液实施处理，该碱液化学氧化溶液包括有无水碳酸钠50g/L、铬酸钠15g/L、氢氧化钠25g/L的混合溶液。
采用碱液化学氧化溶液对铝型材表面实施处理时，碱液化学氧化溶液的温度80-100℃，时间10-20min。
采用上述技术方案，光亮防腐液的配置以及将铝型材实施浸泡后，促使铝型材具有防腐和促进光亮的双重改性效果，提高了铝型材的性能，扩大了铝型材的应用范围。铝型材的表面光洁度以及防腐性得到提高后。通过对铝型材的表面实施处理，消除铝型材表面的有毒物质，从而避免对环境造成污染以及对人体造成损害。而且使铝型材的表面的抗氧化性得到进一步的提高，耐腐蚀性更强。
