本發(fā)明涉及鋁合金技術(shù)領(lǐng)域：，具體涉及一種鋁合金陽極氧化膜封孔劑、制備方法及封閉方法。背景技術(shù)：：鋁合金具有質(zhì)量輕、耐蝕性強(qiáng)、導(dǎo)熱導(dǎo)電良好等優(yōu)點(diǎn)，在航空、航天、汽車、機(jī)械制造、民用工業(yè)中廣泛應(yīng)用。鋁合金的表面處理以陽極氧化為主，但陽極氧化膜層具有多孔結(jié)構(gòu)且具有較強(qiáng)的化學(xué)活性，如果不封孔或封孔質(zhì)量差，環(huán)境中的污染物會被微孔吸附并進(jìn)行深度腐蝕，**終導(dǎo)致鋁材器件使用壽命降低，也就是說，鋁合金陽極氧化膜的封孔質(zhì)量直接決定了鋁合金的耐蝕性，而且鋁合金陽極氧化后一般需要染色處理以得到具有良好外觀效果的外觀件，若不能保證封孔質(zhì)量，也會嚴(yán)重影響鋁合金的外觀形效果。目前，國內(nèi)外通常使用以ni2+及f-為基本成分的ni-f封孔劑，但ni-f封孔體系消耗的鎳及氟太多且又傷害人體的健康；現(xiàn)有的無鎳封孔劑又較難滿足生產(chǎn)上的品質(zhì)要求，無法大規(guī)模應(yīng)用。技術(shù)實(shí)現(xiàn)要素：本發(fā)明主要針對上述現(xiàn)有技術(shù)存在的問題，提供一種鋁合金陽極氧化膜封孔劑，該封孔劑不含鎳，且能夠得到封孔質(zhì)量以及耐蝕性均較好的產(chǎn)品。本發(fā)明方面，提供一種鋁合金陽極氧化膜封孔劑，該封孔劑包括：鉬酸鹽、磷酸鹽、碘的化合物、鑭的化合物、硅烷偶聯(lián)劑和水。本發(fā)明第二方面。湖北鋁合金封孔劑研發(fā)封孔劑，就選仙桃市百事德化工有限責(zé)任公司。</p><div

低pH值有利于Al2O3與F-反應(yīng)，生成AlF63-、\、Al(OH)F53-、、Al(OH)2F43-.。其含量達(dá)到一定值時(shí)，離子間發(fā)生締合、水解和濃縮，轉(zhuǎn)化為穩(wěn)定相絡(luò)合氟化鋁Al2(OH)3F3,。在氧化膜微孔中，Al2(OH)3F3是封孔物質(zhì)；在鋁合金表面，Al2(OH)3F3是粉霜；在槽液中，Al2(OH)3F3是渾濁物。所以槽液溶鋁量太大，鋁合金易上粉，槽液易渾濁死槽。緩蝕劑的添加，正是為了保護(hù)氧化膜不上粉，降低溶鋁量，延長槽液使用壽命。按實(shí)驗(yàn)結(jié)果，有機(jī)醇緩蝕劑的濃度區(qū)間為1-3g/L。（6）螯合劑濃度對封孔質(zhì)量的影響本發(fā)明螯合劑選用乙酸系(如三乙醇胺、乙二胺四乙酸等),磷酸系(如三聚磷酸鈉、焦磷酸鈉、偏磷酸鈉、氨基三甲叉磷酸（ATMP）等)和磷酸基羧酸系（如膦?；⊥槿人幔≒BTCA）等），用其強(qiáng)大的螯合鍵能，穩(wěn)定Ti4+和Al3+,確保槽液不渾濁，鋁合金不上粉。按（2）（5）式，pH升高時(shí)，容易生成Ti(OH)4和Al2(OH)3F3。這些物質(zhì)，若生成在氧化膜微孔，即為封孔物質(zhì)；若生成在鋁合金表面，即為粉；若生成在槽液中，即為渾濁物。螯合劑的加入，提高了Ti(OH)4和Al2(OH)3F3的生成門檻。螯合劑的用量要特別注意，濃度太高，螯合鍵不好打開，封孔能力急劇下降。實(shí)驗(yàn)表明，恰當(dāng)?shù)尿蟿舛葹?-3g/L。。</p><p>
