Abstract
The invention belongs to the field of rust removing agent products and particularly relates to an environment-friendly rust removing agent. By the adoption of an environmental protection formula, the influence on the environment is small after the rust removing agent is used, and therefore the rust removing agent is industrially applied for a long time or on a large scale. Hexamine and pickling inhibitors play a synergistic effect; addition of the pickling inhibitors does not affect removal of rust on the surface of metal but ensures that a fabrication matrix is corroded by acid solutions as little as possible. Meanwhile, a composite surface active agent can be dissolved in the acid solutions, so that dispersion of oil stains and separation and peeling off of a rust layer are facilitated. A layer of oily protective film is formed on the surface of the metal with the rust removed due to selection of oleic acid, regeneration of the rust is effectively prevented, and the metal is kept bright and new for a long time.
Description
Technical field
The invention belongs to rust remover arts, be specifically related to a kind of environment-friendly rust remover.
Background technology
Tradition rust remover not only eliminates rust inefficient, and the high rust remover of efficiency it is likely that go out rust staining, also can not injure the material of matrix, it is most important that environmental pollution is comparatively serious, is unsuitable for long-term or large-scale industry and uses, and contingency question is brought endless trouble. It is thorough then to there is rust cleaning in general Environment-friendlyrust rust inhibitor, or the problem such as repeatability is stronger. Research and develop a kind of environmental protection, rust remover that is efficient and that can effectively prevent rust staining from regenerating has been the task of top priority.
Summary of the invention
The technical problem to be solved is to provide a kind of environment-friendly rust remover, efficiently, environmental protection and while removing rust staining, can protect metal body.
For solving above-mentioned technical problem, the technical scheme is that a kind of environment-friendly rust remover of offer, it is characterised in that proportioning is as follows:
Hydrochloric acid 260-320ml/L;
Phosphoric acid 60-90g/L;
Hexamethylenamine 3-6g/L;
Fatty alcohol-polyoxyethylene ether 10-20g/L;
Triethanolamine 1-3g/L;
Sodium lauryl sulphate 3-6g/L.
Environment-friendly rust remover of the present invention, it is characterised in that also include hexamethylenetetramine and restrainer, additional proportion therebetween is 1:1, and the two amounts to 2-7g/L.
Also including oleic acid, addition is that oil film just covers solution surface and is as the criterion.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts environment-friendly type formula, has fewer environmental impacts after using, and is or large-scale application long-term with industrialization. Hexamethylenetetramine and restrainer can play synergism, and the addition of restrainer neither affects dispelling of metal surface rust staining, can guarantee that again the least possible being corroded by acid solution of product matrix. Further, complexed surfactant can be dissolved in acid solution, and the disengaging of the dispersion and rusty scale that contribute to greasy dirt is peeled off. The selection of oleic acid, can form protecting film one layer oily in the metal surface removing rust staining, effectively prevent the regeneration of rust staining, keeps metal light for a long time as new.
Detailed description of the invention
Embodiment one
