Description
Technical field
The present invention relates to chemical field, especially relate to a kind of normal temperature metal cleaner and preparation technology thereof.
Background technology
Metal cleaner is a kind of surface decontamination agent of the composite synthetic of kinds of surface promoting agent, and it can deoil, decontamination, makes the workpiece surface cleaning dry and comfortable.Be used to remove the metal cleaner of metal surface greasy dirt in the market, normally middle temperature or hot metal clean-out system, and this metalloid clean-out system all has a kind of defective of maximum, just be and heat, if heat then cost is higher with calrod, heat then influence environment if use coal stove instead, also must pay certain cost, how accomplishing to heat just equally to obtain removing the effect of metal surface greasy dirt, is the direction that people study all the time.Though normal temperature metal cleaner has been arranged on the market, and its cost is higher, performance is stable inadequately, and process for preparation is loaded down with trivial details, is easy to produce acid mist, causes environmental pollution, also can cause disadvantageous effect to the user.For example, the acid mist that in cleaning process, produces, not only etching apparatus and factory building, contaminate environment, and can cause people's teeth corrosion, the tooth conjunctiva is rubescent, sheds tears pain, dry throat, symptoms such as cough.
In order to improve, people have carried out long-term exploration, various schemes have been proposed, for example Chinese patent literature discloses a kind of multifunctional special-purpose metal detergent for steel products [application number: 200810019187.4], this metal cleaner is to be raw material with phosphoric acid, sodium tartrate, sodium sulfate, OP-10, SPAN-80, tetrahydroglyoxaline, zinc phosphate, urotropine, sulphur urine, tributyl phosphate, EDTA disodium and ethylene glycol, forms with water is composite.Not only cost is low for this clean-out system, efficient is high, and its Working environment does not have acid mist and occurs, can operating environment of pollution, the pollution-free public hazards of its waste liquid, but the also normal temperature operation down of operation of can heating, meet the processing requirement that streamline is produced, it can use by thin up, also can continue fluid infusion and use, and can reduce use cost greatly, safe in utilization, convenient, efficient.But such scheme still exists and is difficult to preparation, defective such as cost is higher, and cleaning performance is relatively poor.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of compatibility reasonable, cost is lower, and cleaning performance is good, can not produce acid mist, can effectively protect the user, the normal temperature metal cleaner of energy-conserving and environment-protective.
Another object of the present invention is at the problems referred to above, provides a kind of blending process simple, the preparation technology of the normal temperature metal cleaner of easy handling.
For achieving the above object, the present invention has adopted following technical proposal: normal temperature metal cleaner is characterized in that this clean-out system comprises the component of following weight part: 6～8 parts of amphotericses; 0.2～0.4 part in potassium permanganate; 1～2 part of emulsifying agent; 4～8 parts of oxalic acid; 10～20 parts of acid fog inhibitors; 5～10 parts of triethanolamine oleates; 2～4 parts of surface conditioners; 3～6 parts of restrainers; 50～100 parts of the hydrochloric acid of 31～36% concentration; 20～40 parts in water.
The molecule of amphoterics all has amphipathic structure, and a part is hydrophilic, and such as hydroxyl etc., a part is lipophilic, such as aliphatic segment; And amphoterics can play the effect of emulsification, discrete workpieces surface dirt, makes dirt enter solution state, cleans up easily under the effect of abrasive material, protects the excessive scuffing of workpiece surface simultaneously.Emulsifying agent dissolves in the water of any hardness, acid and alkali-resistance. have premium propertiess such as emulsification, level dyeing, moistening and diffusion.Acid fog inhibitor can effectively be avoided in use producing human body being damaged the acid mist of contaminate environment.Surface conditioner can make the metallic surface that the variation of microcosmic takes place, thereby improves the phosphatization effect significantly, can promote to generate the phosphatize phosphate coat of even compact, improves the resistance to corrosion of metal.It can change metallic surface state, acceleration parkerizing process, reduction phosphatization liquid temp, impel the composite chemical material of the phosphatize phosphate coat that forms the trickle densification of crystallization.Surface conditioner can be applicable to the phosphatization front surface and adjusts operation, is adsorbed on the metallic surface with particulate form, becomes that one deck is evenly distributed, a fairly large number of phosphatization crystalline nucleus.Because the nucleus quantity of metallic surface is many, in the crystalline growth process, can be very fast interconnection between the crystal, limit the crystal continued growth, thereby made the phosphatize phosphate coat crystallization fine and closely woven evenly.Use restrainer to make and washed the equipment loss minimizing more than 90%.
In above-mentioned normal temperature metal cleaner, described emulsifying agent is alkylphenol and ethylene oxide condensate.
In above-mentioned normal temperature metal cleaner, described emulsifying agent is the OP-10 emulsifying agent.The OP-10 emulsifying agent is soluble in oil and other organic solvent, is dispersed in the water, has the good emulsifying performance.Has acid-and base-resisting, salt, hard water, performance such as good emulsifying, level dyeing, wetting, diffusion, washing.
