本發(fā)明涉及鋁合金技術(shù)領(lǐng)域：，蘇州無(wú)鎳常溫封孔劑定做，具體涉及一種鋁合金陽(yáng)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(yáng)極氧化為主，但陽(yáng)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(huì)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(shuō)，鋁合金陽(yáng)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(yáng)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(huì)嚴(yán)重影響鋁合金的外觀形效果。目前，國(guó)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(wú)鎳封孔劑又較難滿足生產(chǎn)上的品質(zhì)要求，無(wú)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(duì)上述現(xiàn)有技術(shù)存在的問(wèn)題，提供一種鋁合金陽(yáng)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(yáng)極氧化膜封孔劑，該封孔劑包括：鉬酸鹽，蘇州無(wú)鎳常溫封孔劑定做、磷酸鹽、碘的化合物、鑭的化合物，蘇州無(wú)鎳常溫封孔劑定做、硅烷偶聯(lián)劑和水。本發(fā)明第二方面。</p><div
