Definitions

the invention relates to new phosphate-free formulations of acidic rim cleaning agents which, in addition to the cleaning action, provide temporary corrosion protection on the metal surfaces.
Dirt adhering to rims is composed of both statically positive and negative as well as uncharged particles. Since adhering hard, fine-grained soiling can lead to damage to the metal surfaces during cleaning, the aim of the composition of the washing solutions is to achieve the highest possible emulsifying effects, in particular with respect to the dirt components which are responsible for the adherence. The better this emulsifying and releasing effect, the less force has to be applied to mechanically remove the dirt.
cleaners for steel and light metal rims are therefore aggressive and based on an alkaline or acidic base. They clean the metal surfaces, but also attack them corrosively at the same time, especially phosphates, which were previously used as corrosion inhibitors were used, reduced for ecological reasons, or must be omitted.
metal surfaces treated with the known cleaners must then be rinsed thoroughly with water, dried and then treated in a further step in order to protect them from corrosive attack by external influences and to maintain a shiny, clean surface. This is usually achieved by wax polishing or by applying a clear coat. Both are very complex and only possible with flat surfaces, but not with complex spoke rims. Incidentally, such cleaning and maintenance measures are very time-consuming, so that they are not suitable for carrying out in the commercial field.
the object of the invention is therefore to provide an environmentally friendly rim cleaner available, which is suitable for the treatment of steel as well as light alloy rims, which simply removes dirt adhering to the metal surfaces and at the same time leads to corrosion-protective film formation, so that a time-consuming regrowth and polishing of the rims is no longer necessary.
the low foam formation has proven to be advantageous in this highly effective, phosphate-free cleaning agent even at low doses. which means that only small amounts of water are required for rinsing.
the cleaning solutions prepared from the original concentrate by dilution with water can also be used for a larger number of cleaning processes without the advantageous effects being lost.
the agents according to the invention are not only suitable for individual use, but can also be used in small car washes with special treatments in the range of services.
the rims can also be cleaned here in a simple, time-saving manner without lengthy mechanical treatment and at the same time provided with corrosion protection.
the flowing and collected cleaning solution can be freed from solid particles and oils and fats by filtering or letting it settle and can be reused until the content of soluble contaminants no longer enables satisfactory cleaning.
the concentration of the poly (dimethyl) siloxanes in the diluted cleaning solution is continuously reduced, mainly due to the corrosion-protective film formation on the metal surfaces.
the contaminated cleaning solution can be fed to a normal downstream wastewater treatment plant and can be freed of fat, oil and possibly with separated siloxane-containing components.
the agents according to the invention are produced as concentrates and can be diluted with water as desired. They are just as stable and stable in storage at higher temperatures of around 40 ° C as at temperatures around freezing point.
a polyoxyalkylene lauryl sulfate alkali metal salt is mixed with water at room temperature as the anionic surfactant and to a mixture prepared from 0.5 to 25% by weight of glycolized poly (dimethyl) siloxane, 0.5 to 25% by weight .-% of an aminoalkyl group-containing poly (dimethyl) siloxane and 0.2 to 10 wt .-% of an alkanol monoether or a dialkanol polyether, added and stirred.
This mixture can be mixed with 0 to 15 wt .-% of a nonionic surfactant based on C13 / C15 oxy alcohols with different degrees of ethoxylation or on the basis of linear fatty acid alcohols. 0 to 7% by weight of a wax usually used in car care products can also be stirred in. Depending on the desired effect, 0.5 to 25% by weight of quaternary alkylammonium chloride can be added while leaving out the ammonium surfactant.
the pH of this concentrate is adjusted to a value of 1 to 5 by adding 0.5 to 25% by weight of an organic hydroxycarboxylic acid. It goes without saying that the total composition cannot exceed 100% by weight, and by increasing the Weight fraction of one component, the weight fraction of another component must decrease.
aliphatic or aromatic hydroxycarboxylic acids can be used, such as.
Those with a pKa value of approximately 2.9 to 3.9 and 2 to 8 carbon atoms are particularly suitable.
hydroxycarboxylic acids can include alkali salts of the acids, such as.
K-citrate or Na-citrate can be added, as these further improve the cleaning power of the overall mixture.
Suitable alkali metal salts of a polyoxyalkylene lauryl sulfate are, in particular, those in which the alkoxy groups are methoxy, ethoxy, propoxy or butoxy groups.
a poly (oxyethylene) lauryl sodium sulfate is particularly suitable because, in addition to its particularly good surfactant activity, it is easily biodegradable in wastewater.
cationic surfactants of this type can be used as quaternary alkylammonium chlorides. Particularly well suited are those whose nitrogen is substituted with two long and two short alkyl radicals, such as. B. Dimethyldistearylammoniumchlorid, Didecyldimethylammoniumchlorid or those in which the longer-chain alkyl groups are hydrogenated fatty acids with 14 to 18 carbon atoms.
Straight-chain alkanol monoethers of the formula RO-R'-OH are suitable for mixing the siloxane constituents of the cleaner according to the invention, where R and R 'can be saturated or unsaturated alkyl groups having 1 to 8 C atoms.
Those ethers are preferably used in which the alkanol group is a hydroxymethyl or hydroxyethyl group and R is a butyl, propyl or ethyl group.
polyalcohol polyethers can also be used for this purpose.
Glycol-containing poly (dimethyl) siloxanes with average molecular weights of about 60 Si-O units are added to the cleaner as film formers and wetting agents. These siloxanes are particularly effective in combination with a further siloxane which has aminoalkyl groups as functional groups, the ratio of the dimeric Si-O units to the amino-functional Si- (CH2) x -NH- or Si- (CH2) x NH2 Units is approximately 110: 1 to 155: 1.
these siloxanes are introduced as a nonionic emulsion with small amounts of ethoxylated fatty alcohol as an emulsifier and stirred in.
Rim cleaning agents with the following composition, which can be diluted as desired with water, are particularly suitable for commercial use.
TABLE citric acid 0.5 to 25% by weight 2-butoxyethanol 0.2 to 5% by weight Wacker Silicon® 1656 E 0.5 to 25% by weight Wacker Silicon® LO 3 0.5 to 25% by weight
Repagen® WKT 0.5 to 20% by weight Genapol® LRO 0.1 to 5% by weight water
Rim cleaning agents intended for individual consumption can also be treated with caring waxes.
Such cleaners according to the invention can have the following compositions: TABLE In% by weight citric acid 15 8th 15 15 K-citrate - 0.1 - 5 Wacker® LO 3 10th 10th 10th 5 Wacker® 1656 E. 15 10th 15 - Butyl diglycol 2nd 2nd 2nd 1 water 48 59.9 56 68 Lutensol® A0 7 10th - - 1 Lutensol® ON 70 - 10th - - LGE wax - - 2nd 5
