日常生活中接觸到的各種鋁合金外殼，表面含鎳，對人體造成的持續(xù)傷害，已日益引起社會的高度重視。采用氟鈦酸封孔，其封孔成分為氫氧化鈦，徹底，正好適應(yīng)鋁合金日益深入人類日常生活各方面的大趨勢。但如何用好氟鈦酸，技術(shù)難度非常大。按（3）式，pH升高，氟鈦酸分解出氫氧化鈦，正好是所需要的封孔成分。按（2）式，氟鈦酸水解，電離出F-；按（4）式，F(xiàn)-與氧化膜反應(yīng)，釋放出OH-，使槽液pH升高。F-是促進(jìn)封孔物質(zhì)氫氧化鈦和氟鋁絡(luò)合物Al2(OH)3F3形成的關(guān)鍵離子。如上所述，氟鈦酸有鈦有氟，完全可作為封孔劑的主要成分，且封孔速度快，封孔溫度低。但研發(fā)中遇到以下幾個(gè)致命難題：（1）從分子式看，氟鈦酸與氟化鎳相比，氟太高，易結(jié)粉霜;（2）氟鈦酸pH工作點(diǎn)太低，當(dāng)pH值大于，槽液分解，形成氫氧化鈦沉淀，封孔優(yōu)化區(qū)間只能在3-4之間；（3）氟高，pH值低，鋁合金表面氧化膜易被腐蝕；（4）氟高，pH值低，溶鋁量太大，槽液易渾濁，鋁合金易上粉。只有解決高氟、低pH值下氧化膜被腐蝕、鋁合金上粉、槽液渾濁的難題，才能有效使用氟鈦酸，實(shí)現(xiàn)無鎳封孔。為此，選用緩蝕劑和螯合劑，與氟鈦酸配伍，解決高氟、低pH值下鋁合金上粉和槽液渾濁難題。緩蝕劑。</p><div

本發(fā)明屬于材料制備領(lǐng)域，特別涉及一種高載硒量的介孔二氧化硅長效納米材料的制備方法。背景技術(shù)：硒作為人體必需的微量元素之一，是人體多種酶的組成成分。一直以來，它在、拮抗重金屬、增強(qiáng)人體免疫功能等方面發(fā)揮著重要作用。有研究顯示硒納米顆粒與乙酰膽堿氯化物和槲皮素復(fù)合對超級細(xì)菌具有高和活性，并且不會產(chǎn)生耐藥性。另外，有研究發(fā)現(xiàn)羥基磷灰石上的納米硒涂層對銅綠假單胞菌和金黃色葡萄球菌具有良好的性。從生物安全性的角度考慮，硒元素的內(nèi)源性與或外源性生長因子的高成本、復(fù)雜的制造和非預(yù)期的副作用相比，具有更加可靠的安全性和經(jīng)濟(jì)性。但是硒的營養(yǎng)活性劑量與其毒性劑量之間范圍較窄，過量會導(dǎo)致硒中毒。納米硒的發(fā)明不僅保留了傳統(tǒng)硒的優(yōu)點(diǎn)，并能有效改善這一難題。然而，納米硒極易發(fā)生團(tuán)聚，嚴(yán)重影響其生物活性和生物利用度。因此，構(gòu)建適當(dāng)?shù)募{米硒可調(diào)節(jié)釋放體系，可以降低其副作用和提高其生物學(xué)活性。介孔二氧化硅(msns)因其粒子尺寸均一可調(diào)、可調(diào)節(jié)的介孔結(jié)構(gòu)、載藥效率高、生物相容性好和易功能化及表面修飾等優(yōu)勢，被用于構(gòu)建速釋、緩釋和控釋系統(tǒng)等方面。</p></p><br
