Definitions
- the invention relates to anti-corrosion agents and corrosion inhibitors, Which Lactobionic acid alkylamine amides and / or di-lactobionic acid alkyl diamides contain.
- lactobionic acid amides are known as corrosion-inhibiting agents known.
- EP 550 278, EP 541 467, EP 688 781 and EP 748 813 are lactobionic acid alkylamides, Di-lactobionic acid amides, lactobionic acid aminamides and bisamides and their use as a surface-active agent described. In particular, these connections are based on their properties in detergents application.
- the present invention is therefore based on the object new anti-corrosion agents and anti-corrosion agents To provide agents.
- Lactobionic acid alkylaminamides their saturated or unsaturated bound via the amide function Alkyl group has a chain length of 8 to 30 carbon atoms have, and Di-Lactobionklarealkyldiamide, whose about the amide function bonded saturated or unsaturated alkyl group have a chain length of 8 to 30 carbon atoms, have a corrosion-inhibiting effect.
- the subject of the invention is the use of the compounds mentioned or their mixtures as anti-corrosion agents and / or as an additive in metalworking agents for treatment of metals.
- the treatment of the metals can be done by dipping, Coating, spraying with the agents according to the invention.
- lactobionic acid alkylaminamides and / or di-lactobionic acid alkyl diamides by the implementation of lactobionic acid or reactive Lactobionic acid derivatives, preferably lactobionic acid lactone, with an ⁇ , ⁇ -primary diamine or an ⁇ , ⁇ -primary diamine mixture were used.
- ⁇ , ⁇ primary diamines within the scope of the invention, ⁇ , ⁇ primary fatty diamines denotes the aliphatic residue of a fatty acid with 8 contain up to 30 carbon atoms.
- These fat diamonds can e.g. B. technically obtained from fatty acids in known Way to be implemented to the corresponding diamines.
- Prefers are fatty diamines or their mixtures that are made from natural occurring or technical fatty acid mixtures obtained were used. The proportion of unsaturated fatty diamines fluctuates between approx. 5 and 85% by weight.
- the corrosion protection agent used according to the invention preferably contains the lactobionic acid alkylaminamides and / or the di-lactobionic acid alkyl diamides in the form of an aqueous solution.
- the aqueous solutions can be used alone or in a mixture with other compounds used as an anti-corrosion agent or inhibitor become.
- the content of lactobionic acid derivatives, based on the aqueous solution can be the usual for anti-corrosion agents Concentration range, expediently in the concentration range from 0.01 to 20% by weight, e.g. B. in the concentration range from 0.5 to 10% by weight.
- the anti-corrosion agents or inhibitors used Lactobionic acid alkylaminamides and / or dilactobionic acid alkyl diamides in an aqueous solution may contain completely clear solutions or, in particular in the presence of other compounds, finely divided emulsions be transparent, opaque or milky.
- lactobionic acid derivatives used can also be used for corrosion protection agents usual connections, e.g. B. petroleum sulfonates, Mineral oils or other additives are mixed and used Treatment of metals can be used.
- the lactobionic acid derivatives used according to the invention show emulsifying and corrosion-inhibiting effects in mineral oil-containing, aqueous metalworking agents.
- Another The invention therefore relates to their use in particular water-containing metalworking agents. Under metal working tools are all common for metalworking Liquids, especially cooling lubricants, drilling, Cutting and grinding oils, rust removal, paint stripping and passivation agents Understood. It is therefore possible to use metalworking emulsions to produce which contain a high level of water, without rusting.
- the corrosion protection used is characterized by good corrosion protection Lactobionic acid derivatives thanks to excellent skin tolerance and high biodegradability.
- lactobionic acid derivatives The corrosion-inhibiting effect of lactobionic acid derivatives was by means of the chips / filter paper method according to the DIN 51360, part 2, determined.
- the anti-corrosion properties were determined in accordance with the DIN standard 51360, part 2.
- Gray cast iron chips (material DIN 1691-GG30 of approx. 5 mm x 5 mm size) were washed with petroleum ether, through a wire sieve sieved and dried at about 105 ° C in a drying cabinet. After drying did not touch the chips by hand.
- a round filter made of filter paper (diameter 40 mm) was placed in a Petri dish and evenly sprinkled with 2 g ( ⁇ 0.1 g) of the dried chips. The chips were then uniformly wetted with 2 ml of the solution to be examined using a full pipette. The lid of the Petri dish was put on and the Petri dish was left to stand for 2 hours at room temperature. Then the chips were removed from the round filter, the round filter rinsed under running water, swirled in acetone for about 5 seconds and dried at room temperature. Immediately after cleaning and drying the round filter, the degree of corrosion of the corrosion marks on the round filter was determined by visual inspection. The degree of corrosion determined for the anticorrosive agents according to the invention is given in the table below.
