【摘要】:導(dǎo)電高分子材料是一種新型的研究材料,經(jīng)過近幾十年無數(shù)科研工作者的不斷探索,目前已經(jīng)成功發(fā)展到金屬防腐、超級電容器、傳感器、隱身材料、電致變色、電致發(fā)光、自愈合等等多個方面,而面對目前大量金屬腐蝕所帶來的嚴(yán)重后果,找到有效遏制金屬腐蝕的方法更是十分迫切。因此,尋找合適的導(dǎo)電高分子材料來防止金屬腐蝕成為一個很重要的課題。針對聚苯胺的獨特的合成機(jī)理,本文主要通過化學(xué)合成法合成的聚苯胺來對金屬進(jìn)行防腐處理,分別通過聚苯胺壓片、聚苯胺化學(xué)連接和聚苯胺電鍍?nèi)N形式的防腐材料來與金屬進(jìn)行連接。實驗中主要以304不銹鋼金屬片來作為研究對象,對比測量了三種連接方式的金屬連接聚苯胺前后,金屬在相同酸液濃度下因腐蝕而導(dǎo)致的質(zhì)量變化,計算得出聚苯胺對金屬的陽極保護(hù)效率分別為99.82%,87.61%,94.51%。鑒于聚苯胺壓片連接不穩(wěn)定,聚苯胺化學(xué)連接時無法確定粘附在金屬上的聚苯胺量,最終選定電鍍?yōu)樽罴堰B接聚苯胺同金屬的方式。同時探究了聚苯胺對四種純金屬鐵、錳、鉻、鉬及含有這四種金屬成分的混合金屬304不銹鋼的作用,并考慮了電鍍時間、電鍍電流、介質(zhì)酸性溶液的濃度、溫度等條件對聚苯胺防腐效果的影響,并通過實驗得出聚苯胺對于上述五種金屬的防腐效果分別為89.51%、92.92%、94.59%、97.12%、96.35%。根據(jù)企業(yè)中應(yīng)用的酸化緩蝕劑的技術(shù)要求,電鍍聚苯胺,測試純鐵片,二級,測試純鉻片,二級,測試純錳片,一級,純鉬片,一級,304不銹鋼金屬片,一級。結(jié)果表明,介質(zhì)腐蝕酸液濃度和溫度的改變對金屬溶解速度有所影響,但不能改變聚苯胺對于金屬具有的防腐效果。在電鍍聚苯胺過程中,電鍍電壓電鍍時間的增加雖有利于產(chǎn)生更好的聚苯胺防腐效果,但考慮實際應(yīng)用,適當(dāng)?shù)碾婂儠r間與電鍍電壓的選擇是必須的。實驗結(jié)果表明,聚苯胺對金屬有很好的防腐效果,找到合適的連接方法將其很好的連接到金屬片上即可獲得很好的防腐效果。
[Abstract]:The conductive polymer material is a new kind of research material. Through the continuous exploration of numerous scientific researchers in the last few decades, it has been successfully developed into metal anticorrosion, supercapacitor, sensor, stealth material, electrochromic, electroluminescence, self healing and so on, and the serious consequences brought by a large amount of metal corrosion, It is very urgent to find effective methods to prevent metal corrosion. Therefore, it is a very important task to find suitable conductive polymer materials to prevent metal corrosion. In this paper, the special synthesis mechanism of polyaniline is used to prevent corrosion of metal by polyaniline, which is synthesized by chemical synthesis method. Three kinds of anticorrosive materials, polyaniline chemical connections and polyaniline electroplating, are used to connect with metals. In the experiment, 304 stainless steel sheets are used as the research objects. The quality changes of metal in the same acid concentration and corrosion are measured and measured by 304 stainless steel sheets. The anodic protection efficiency of aniline to metal is 99.82%, 87.61% respectively. 94.51%., in view of the instability of the polyaniline bonding, can not determine the amount of polyaniline adhered to the metal when the polyaniline chemical connection is connected. Finally, electroplating is selected as the best way to connect polyaniline with metals. At the same time, polyaniline has been explored for four kinds of pure metal iron, manganese, chromium, molybdenum and containing. There are four kinds of metal mixed metal 304 stainless steel, and the effect of electroplating time, electroplating current, concentration of medium acid solution, temperature and other conditions on the anticorrosion effect of polyaniline is considered. Through the experiment, it is concluded that the anticorrosion effect of polyaniline on the above five kinds of metals is 89.51%, 92.92%, 94.59%, 97.12%, 96.35%., according to the enterprise The technical requirements of acidification inhibitors used in the industry, electroplating polyaniline, testing pure iron sheet, grade two, testing pure chromium tablets, grade two, testing pure manganese slices, first grade, pure molybdenum sheet, first grade, 304 stainless steel sheet, first grade. The results show that the change of concentration and temperature of medium corrosion acid has some influence on the dissolution rate of metal, but it can not change polyaniline for gold. In the process of electroplating polyaniline, the increase of electroplating voltage electroplating time is beneficial to the production of better anticorrosion effect of polyaniline, but considering the practical application, the choice of the appropriate electroplating time and electroplating voltage is necessary. The experimental results show that polyaniline has a good anticorrosion effect on the metal and finds a suitable connection. The method can connect well to the metal sheet to achieve good anticorrosion effect.
