本發(fā)明屬于金屬或合金材料制備工藝技術(shù)領(lǐng)域，具體涉及一種可長期儲存陽極氧化未封孔金屬印刷材料及其制備方法和應(yīng)用。背景技術(shù)：金屬或合金經(jīng)過常規(guī)的陽極氧化處理后形成的陽極氧化層中存在大多數(shù)的微孔，這些微孔的存在是用于將印刷時的噴出的墨水吸入孔中，進而完成對陽極氧化金屬或合金的印刷。常規(guī)金屬或者合金在經(jīng)過陽極氧化處理后，陽極氧化層暴露在含有水分子和氧氣的環(huán)境中，此種環(huán)境會使經(jīng)陽極氧化處理后的金屬或者合金的陽極氧化層表面與水分子和氧氣產(chǎn)生化學(xué)反應(yīng)，在陽極氧化層上會形成氫氧化物。當氫氧化物侵入到微孔中后，會直接引起微孔孔徑變小，或者是引起微孔堵塞。之后隨著反應(yīng)時間的延續(xù)，多數(shù)陽極氧化層中的微孔均會處于被堵塞的狀態(tài)。微孔出現(xiàn)孔徑變小或是引發(fā)堵塞，會直接對陽極氧化金屬或者合金對墨水的吸入效率及吸入量產(chǎn)生很大的影響，進而影響陽極氧化金屬或者合金的成像質(zhì)量問題，這也是目前常用的陽極氧化金屬或者合金中經(jīng)常出現(xiàn)染料擴散不均勻和顏色混亂的原因所在。對于上述問題的出現(xiàn)，是由于現(xiàn)有的技術(shù)中通過對金屬或者合金進行陽極氧化處理后，此時微孔保持開啟狀態(tài)，因此必須要在當時的環(huán)境下馬上進行著色印刷，之后將微孔封閉后方可出廠。泰州供應(yīng)封孔劑定做封孔劑選哪家，百事德為您服務(wù)！期待您的光臨！</p><div
