Abstract
The invention relates to an automobile part low-temperature anticorrosion protective agent which comprises 2-mercaptobenzothiazole MBT, 2-mercaptobenzimidazole MBI, 2-mercaptobenzoxazole MBO, benzotriazole BTA, a lubricant and a surfactant. On a weight basis, the ratio of 2-mercaptobenzothiazole MBT:2-mercaptobenzimidazole MBI:2-mercaptobenzoxazole MBO:benzotriazole BTA is 0.5:3:0.5:1.
Description
Technical field
The invention belongs to sanitas and surface treatment agent field, refer to especially a kind of auto parts low-temperature corrosion protection protective material.
Background technology
In automotive field, in order to reduce the deadweight of carwash, to reduce automobile to the consumption of basic energy, seeking lightweight always, the material that intensity is high substitutes the use of iron type materials, although existing had highstrenghtpiston's technology to be in the news, but because there is high temperature in some parts in the automobile, the reasons such as strong motion, this class material can not be used, and many auto parts come alternative metals iron with aluminium alloy now, and this is because some aluminum alloy materials have lightweight, the characteristics high temperature resistant, that intensity is high.But aluminium alloy is also the same with iron type materials, has etching problem.
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 in aviation and navigation 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.
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 low-temperature corrosion protection in the auto parts.
The present invention is achieved by the following technical solutions:
Auto parts low-temperature corrosion protection protective material, its composition comprises: 2-mercaptobenzothiazole MBT, 2-mercaptobenzimidazole MBI, 2-sulfydryl benzothiazole MBO, benzotriazole BTA, lubricant and tensio-active agent.
Be by weight percentage described 2-mercaptobenzothiazole MBT: 2-mercaptobenzimidazole MBI: 2-sulfydryl benzothiazole MBO: benzotriazole BTA is 0.5: 3: 0.5: 1.
Described lubricant is one or both combinations in stearic acid, butyl stearate or the oleylamide.
Described tensio-active agent is one or both combinations in Nonyl pheno, aliphatic acid polyethenoxy ether sodium sulfate or the aliphatic acid polyethenoxy ether ammonium sulfate.
The invention has the beneficial effects as follows:
By using above anti-corrosive protecting agent to utilize benzotriazole to form the conjugation complex compound with the aluminium on auto parts surface, this complex compound is insoluble to the solution such as acid, alkali, can be good at playing a protective role.

Described tensio-active agent is one or both combinations in Nonyl pheno, aliphatic acid polyethenoxy ether sodium sulfate or the aliphatic acid polyethenoxy ether ammonium sulfate.
The preparation method of described auto parts surface low-temperature anti-corrosive protecting agent is; with the 2-mercaptobenzothiazole MBT that forms in proportion; 2-mercaptobenzimidazole MBI; 2-sulfydryl benzothiazole MBO and benzotriazole BTA join in the sealed vessel that organic solvent is housed; heating in water bath stirs and makes the complexing agent dissolving; described bath temperature is 30-40 ℃; being mixed with is 1.0% solution by weight percentage, then adds the lubricant and above-mentioned four kinds of tensio-active agents that the material gross weight is identical of 1/2 above-mentioned four kinds of material gross weights.
Described organic solvent is one or more combinations in ethylene dichloride, trichloroethane, trichloromethane, ethanol, acetone or the epoxy chloropropane.
Protectant using method:
Auto parts are coated with pre-treatment: with machinery, chemical or electrochemical method depositing dust, go out degreasing and various erosion (workpiece needn't be coated with pre-treatment after electroplating).
Phosphatization: preparation NaH
2PO
4-H
3PO
4Solution is as phosphorization agent, and phosphating time is 3min;
Clean: use first the dehydrated alcohol degreasing, with distilled water workpiece is cleaned, clean surface makes its surface for neutral.
Dry: workpiece must be dry before the coating, and protective material contacts with water when avoiding applying, impact effect.Usually can put into the loft drier constant weight.
Apply: the workpiece after the clean dried is put into filled protectant container, immersion plating 15-20min takes out.Also can brush, spraying and showering.
Dry: under ventilation condition, place and both could in 1-2 minute.
