Description

Normal temperature metal cleaner and preparation technology thereof

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.
