Abstract
The invention relates to an anti-corrosion and color-fixing agent for a surface of aluminum alloy. The anti-corrosion and color-fixing agent for the surface of the aluminum alloy consists of the components of 2-MBI (2-mercaptobenzimidazole), 2-MBO (2-mercaptobenzothiazole), BTA (benzotriazole), imidazole derivative, a lubricant and a surface active agent, wherein the weight percentage of the 2-MBI to the 2-MBO to the BTA to the imidazole derivative is 2.5:0.5:1:1.
Description
Technical field
The invention belongs to sanitas and anti-variable color field, refer to especially the anticorrosion and laking agent of a kind of aluminum alloy surface.
Background technology
Equipment and the product of aluminium and alloy thereof are widely used at each department of national economy, and especially in chemical industry and petrochemical industry, because aluminium alloy has the high excellent properties of light weight intensity, the in recent years application on aviation, navigation and automobile also is taken seriously day by day simultaneously.
The corrosion that aluminium alloy occurs under various environmental activities spreads all over each department of national economy, brings about great losses, and has huge meaning for the research of metal protection.In the guard technology of various metallic corrosion, the inhibiter technology is simple owing to technique, suitability becomes by force one of effective and the most the most frequently used method.But the inhibiter technology has obvious limitation, and in the liquid phase medium that inhibiter is most widely used, inhibiter must have certain solubleness, and must reach certain concentration.Traditional inhibiter has caused pollution because toxicity is larger to environment; Simultaneously, because the inhibiter consumption is less, extraneous small variation will cause larger impact to system, and this has brought very large difficulty also for the research of inhibition mechanism, these effects limit further developing of inhibiter.
People study all the time and use various controls or prevent method and the technology of metallic corrosion.Use the method for maximum several control metallic corrosion to have in the practice: correct metallic substance and the appropriate design metal construction selected; Electro-chemical protection; Adopt protective coating; Change environment composition, add inhibiter; Self-assembled monolayer forms the inhibitor molecular protective membrane.
The surface metal of aluminium alloy reacts together with employed coating with pigment and uses the product of aluminium alloy manufacturing to fade easily simultaneously, how to prevent that fading of Al-alloy products from also being the important topic of this area.
Summary of the invention
The objective of the invention is by the improvement to existing self-assembled monolayer technology, to improve a kind of anti-corrosive protecting agent of aluminum alloy surface rot-resistant.
Another object of the present invention is the COLOR FASTNESS PROBLEM that can solve Al-alloy products by the technical program.
The present invention is achieved by the following technical solutions:
Anticorrosion and the laking agent of aluminum alloy surface, its composition comprises: 2-mercaptobenzimidazole MBI, 2-sulfydryl benzothiazole MBO, benzotriazole BTA, imdazole derivatives, lubricant and tensio-active agent.
