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(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，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(huì)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(duì)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。</p><p> 本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料。本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料的應(yīng)用。本發(fā)明采用溶膠-凝膠方法制備得到介孔二氧化硅(msns)，并進(jìn)一步利用化學(xué)刻蝕法處理獲得一種較大孔徑的介孔二氧化硅，然后通過超聲輔助-熔融滲透方法(ultrasonicationassisted-meltinfiltration，ua-mi)負(fù)載高量納米硒(se)，超聲條件下將抗壞血酸溶液迅速滴加入硒源和擴(kuò)孔的介孔二氧化硅溶液中反應(yīng)，得到混合溶液，然后將混合溶液冷凍干燥，煅燒，這樣可以使納米se充分填充在孔道內(nèi)，從而負(fù)載高量納米硒，由于納米se充分填充在孔道內(nèi)，可達(dá)到緩慢持久的釋放效果。本發(fā)明制備的擴(kuò)孔的msns平均孔徑和孔容分別為，將其作為載體負(fù)載納米硒se得到的se-msns，其中含硒量比較高可達(dá)45wt.％，且負(fù)載量在5wt.％-45wt.％可精確調(diào)控，粒徑為119±4nm。本發(fā)明中se-msns功能單元結(jié)構(gòu)穩(wěn)定、尺寸可控、具有良好的分散性，更重要的是可以利用更少量的msns負(fù)載更多量的se，提高了納米se的負(fù)載率和msns的利用率。有益效果本發(fā)明獲得的se-msns具有載硒量高、可調(diào)控性強(qiáng)，分散性好，顆粒均一，se可以充分填充在msns的孔道中。相較于純se。封孔劑哪家質(zhì)量好，詳細(xì)可訪問百事德官網(wǎng)查看！</p><div
