class="box"><p><p> 本發(fā)明涉及鋁合金技術領域：，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：：鋁合金具有質量輕、耐蝕性強、導熱導電良好等優(yōu)點，常州鋁合金常溫無鎳封孔劑封閉，在航空、航天、汽車、機械制造、民用工業(yè)中廣泛應用，常州鋁合金常溫無鎳封孔劑封閉。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構且具有較強的化學活性，如果不封孔或封孔質量差，環(huán)境中的污染物會被微孔吸附并進行深度腐蝕，**終導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，若不能保證封孔質量，也會嚴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)上的品質要求，無法大規(guī)模應用。技術實現(xiàn)要素：本發(fā)明主要針對上述現(xiàn)有技術存在的問題，提供一種鋁合金陽極氧化膜封孔劑，常州鋁合金常溫無鎳封孔劑封閉，該封孔劑不含鎳，且能夠得到封孔質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。封孔劑哪家好，詳情可以訪問百事德！常州鋁合金常溫無鎳封孔劑封閉</p><div

所述硅烷偶聯(lián)劑的含量為；所述苯磺酸鹽的含量為。本發(fā)明第二方面，提供一種鋁合金陽極氧化膜封孔劑的制備方法，將上述鋁合金陽極氧化膜封孔劑中的鉬酸鹽、磷酸鹽、碘的化合物、鑭的化合物和硅烷偶聯(lián)劑溶于水形成鋁合金陽極氧化膜封孔劑。本發(fā)明第三方面，提供一種鋁合金陽極氧化膜封閉方法，將經(jīng)過陽極氧化處理的鋁合金與封孔劑接觸，得到鋁合金基材，所述封孔劑為上述鋁合金陽極氧化膜封孔劑。推薦地，所述鋁合金與封孔劑接觸的溫度為80-96℃，時間為20-50min。具有陽極氧化膜的鋁合金與封孔劑的接觸溫度在上述推薦范圍內(nèi)，鋁能夠生成氫氧化鋁并配合封孔劑各組分形成的氫氧化物、填充物及絡合物等將陽極氧化膜孔隙封閉。下面通過實施例對本發(fā)明作進一步的說明。應當理解，此處所描述的具體實施例*用以解釋本發(fā)明，并不用于限定本發(fā)明。本發(fā)明中所述實施例中的所有原料如非特指，均為市售產(chǎn)品。實施例1按照表1列出的組分制備鋁合金陽極氧化膜封孔劑；制備鋁合金陽極氧化膜封孔劑：將鉬酸鈉、三聚磷酸鈉、碘化鉀、氯化鑭、硅烷偶聯(lián)劑和十二烷基苯磺酸鈉溶于水形成鋁合金陽極氧化膜封孔劑a1。所述鉬酸鈉的含量為2g/l，三聚磷酸鈉的含量為，碘化鉀的含量為5g/l。無錫鋁氧化封孔劑用途封孔劑哪家質量好，詳細可訪問百事德官網(wǎng)查看！</p><div

上述著色印刷的過程中，無論是著單一的純色或是著多色，均需要在氧化廠內(nèi)完成。該種陽極氧化金屬或者合金的處理方式得到的產(chǎn)品的使用有效期為一個月，有效期較短，對于整個著色印刷工藝的要求和環(huán)境等方面較為苛刻，并且極易引起微孔的堵塞或孔徑的變小帶來的著色不均勻。目前常規(guī)的對于金屬或者合金經(jīng)過陽極氧化處理后裝進塑料袋內(nèi)充好氮氣后封口進行儲存，然后完成對陽極氧化金屬或者合金的運輸及保存。該種陽極氧化金屬或者合金的儲存使用期限短，包裝極為復雜，同時也無法進行沖孔、折彎或者裁剪等深加工工藝的進行。傳統(tǒng)的加工鋁銘牌的工藝中常使用蝕刻、絲印和雕刻等方式，這些工藝的運用均不符合國家所示的環(huán)保要求，而且隨著企業(yè)工藝的不斷成長，傳統(tǒng)的生產(chǎn)工藝已無法達到國家環(huán)保要求標準。顯然，對于陽極氧化處理后未封孔的金屬或者合金而言，能夠保持微孔的持續(xù)開放、使用有效期限長、便于進行著色印刷、便于包裝、便于運輸、便于進行各種深加工、符合國家環(huán)保標準的材料是亟待解決的問題。技術實現(xiàn)要素：為了解決現(xiàn)有技術存在的上述問題，本發(fā)明目的在于提供一種可長期儲存陽極氧化未封孔金屬印刷材料的制備方法。</p><p>
