Definitions
- the invention relates to a corrosion inhibitor for metallic components.
- a corrosion protection coating on a metallic component in particular a component with a high content of iron, for.
- a steel component to protect the component from oxidative corrosion and be environmentally friendly.
- a corrosion inhibitor which is to be used for the production of anti-corrosion coatings on metallic components, is also often required that this does not bother after a shoring of components in machinery or equipment or does not need to be removed before installation, which is complicated and therefore undesirable .
- anticorrosive coatings usually consist of oily or oil or greasy coatings. These coatings are often paraffinic, naphthenic or aromatic mineral oils or synthetic or natural fats or oils. These known anti-corrosion coatings serve to seal a surface of components by an oil or grease layer against moisture and oxidative attack. During or after assembly of the components thus protected, the anticorrosive coatings are in many cases troublesome and therefore undesirable. The components are therefore usually degreased and cleaned prior to installation in complex processes. This not only leads to considerable environmental pollution, but also to considerable additional costs.
- Aqueous corrosion inhibitors which contain carboxylic acids and phosphate esters have also become known from the prior art. Although such corrosion inhibitors are intended to delay an oxidative attack on metallic components, they are not or only insufficiently compatible with aqueous lubricant compositions. From the document JP 2003013263 A, an aqueous corrosion inhibitor has become known, which can be used for components made of steel. According to this document, an aqueous corrosion inhibitor is disclosed, which in addition to water and additives such as surfactants and thickeners, for. As kaolin, clay or mica, pigments containing which should ensure corrosion protection. The pigments which z.
- Example of phosphates such as zinc phosphate or magnesium phosphate have an average particle size of at most 3 microns.
- an average particle size of the pigments is chosen to be small so that the pigments do not agglomerate.
- a corrosion protection effect of such a corrosion inhibitor is based essentially exclusively on the effect caused by the pigments, which is unsatisfactory for a sustainable corrosion protection.
- it can not be ruled out, despite the small particle size, that the intended pigments agglomerate.
- the object of the invention is to provide a corrosion protection agent of the type mentioned, which allows a good coating of metallic components, possibly also oiled or greased metallic components, the corrosion inhibitor or a corrosion protection coating created from this must be removed neither from obstructing the components still disturbs after installation and wherein the corrosion inhibitor or the anti-corrosion coating created from this has great corrosion protection, is environmentally compatible and compatible with an aqueous lubricant fluid.
- a corrosion inhibitor which comprises (by weight): a) more than 50% water; b) a surfactant; c) a boric acid derivative; d) a platelet or rod-shaped filler; e) optionally a binder; f) optionally a carboxylic acid salt.
- a corrosion inhibitor according to the invention has a double anti-corrosion effect.
- the platelet-shaped or rod-shaped filler whose particles have a very high aspect ratio, ie a large ratio of particle diameter or length to particle thickness, seals them off by the attachment of particles to the surface of the component, so that very long diffusion paths are corrosive acting substances arise, which come into contact with the coated surface.
- a physically effective corrosion protection mechanism is given.
- a boric acid derivative is provided, for example a reaction product of boric anhydride with triethanolamine, so that a chemically effective corrosion protection mechanism is also provided.
- a corrosion protection coating can be produced, which has no or only a small number of capillary channels for gases such as air and also protects the coated surface in a chemical manner.
- the surface is not only quasi-diffusion-proof, but also chemically passivated.
- the corrosion inhibitor according to the invention is completely compatible with aqueous or aqueous lubricating or cooling liquids, wherein surprisingly it has been shown in relation to aqueous lubricating fluids that a lubricating effect is increased by the interaction of a corrosion inhibitor according to the invention in the form of a corrosion protection coating with aqueous lubricating fluids is because the corrosion inhibitor of the invention leads to a reduction of a friction coefficient.
- the anticorrosive agent comprises a platelet-shaped filler.
- Particularly suitable fillers are selected from the group consisting of graphite, mica, hexagonal boron nitride, talc, kaolin and iron mica. It also proves favorable in this regard that an average particle diameter of the platelet-shaped filler is less than 15 ⁇ m, preferably less than 10 ⁇ m, in particular less than 7.5 ⁇ m. An average particle diameter is preferably 0.5 to 5.0 ⁇ m.
- any substances which lower a surface tension can be used as surfactants.
- Such surfactants or wetting agents have the advantage that good wetting performance can be achieved without toxic or environmentally harmful side effects are to be feared.
- acetylene derivatives a corrosion inhibitor having a particularly high corrosion protection effect can be produced, although the interaction of this component with the other corrosion protection active components of the anticorrosive agent has not yet been clarified.
- a binder from the group of polysaccharides can be added to the corrosion protection agent.
- a carboxylic acid salt selected from the group consisting of zinc stearate, calcium stearate, aluminum stearate, zinc oleate, calcium oleate and aluminum oleate may be provided in a corrosion inhibitor according to the invention, which has proved to be advantageous.
- a corrosion inhibitor according to the invention is essentially free of phosphates, which represents a further advantage with regard to environmental compatibility.
- the corrosion inhibitor comprises greater than 80%, preferably greater than 90%, water.
- An amount of the fillers can be chosen arbitrarily in a wide range.
- a preferred range in which a high corrosion protection effect is given, but the corrosion inhibitor can also easily be processed or applied to metallic components is 0.5 to 30%, preferably 0.5 to 5.0%.
- An amount of the surfactant in the anticorrosion agent is preferably in the range of 0.1 to 2.0%. In this area, the benefits of the surfactant come fully to fruition. at Lower levels may not be given a desired effect of the surfactant. Even higher contents than 2.0% can be disadvantageous.
- a corrosion inhibitor according to the invention is preferably used for components made of a steel alloy.
- An application of the corrosion inhibitor can be carried out in any manner, in particular by immersing a component or spraying the corrosion inhibitor on the component.
- Example 1 92.0 liters of demineralized water are introduced and 2.0 kg of polyvinyl alcohol (fully hydrolyzed, viscosity 30 mPas 2ig% Hoppler) dissolved and added 0.5 kg of acetylene glycol. Thereafter, 2.5 kg of graphite (d50 4.0 microns, and 99.5% carbon) and 2.0 kg of zinc stearate and 1, 0 kg of boric acid derivative (prepared according to Example 1) are added. The corrosion inhibitor prepared in this way can be used according to Example 1.
- Example 3 92.0 liters of demineralized water are introduced and 2.0 kg of polyvinyl alcohol (fully hydrolyzed, viscosity 30 mPas 2ig% Hoppler) dissolved and added 0.5 kg of acetylene glycol. Thereafter, 2.5 kg of graphite (d50 4.0 microns, and 99.5% carbon) and 2.0 kg of zinc stearate and 1, 0 kg of boric acid derivative (prepared according to Example 1) are added. The corrosion inhibitor prepared
- Example 1 According to the method of Example 1 90.0 liters of demineralized water are introduced and added 0.5 kg of acetylene glycol. Then there are 3.5 kg
- Methylcellulose (viscosity 300 mPas 2% Höppler) dissolved. It will then be 2.5 kg
- Example 1 The corrosion inhibitor can be used according to Example 1.
