Definitions

  • the present invention relates to a new aqueous cleaning agent.
  • the present invention also relates to the use of the new aqueous detergent for removing residues, which physically and / or thermally and optionally with actinic light contain or consist of hardenable constituents, from containers, Pipelines, pumps and other equipment, such as Application units of application systems with such components or come into contact with products containing such components are.
  • the present invention relates to a new method for Removal of residues, which are physically and / or thermally as well optionally contain constituents curable with actinic light or from them consist of containers, pipes, pumps and other equipment such as for example application units.
  • residues which are physical and / or aqueous and optionally curable with actinic light Coating agents originate to be removed with aqueous cleaning agents.
  • aqueous cleaning agents are used, which in addition to butyl diglycol contain organic amines such as dimethylethanolamine.
  • the containers, pipes, pumps and other equipment such as for example application units of application systems with the known aqueous cleaning agents are rinsed several times to all Remove residues.
  • the object of the present invention is a new aqueous cleaning agent To provide which the disadvantages of the prior art no longer has, but it allows residues, which are physical and / or Components curable thermally and optionally with actinic light contain or consist of containers, pipes, pumps and other equipment, such as application units from Application systems, completely and reliably removed quickly. This is supposed to also be possible with residues that are physically and / or thermally and optionally contain components curable with actinic light, which physically and / or thermally and optionally with actinic Light-curable aqueous coating materials, adhesives or Sealants, but especially physically and / or thermally curable Water-based paints come from.
  • the new method for removing residues which physically and / or thermally and optionally with actinic light contain or consist of hardenable constituents, from containers, Pipelines, pumps and other equipment, such as Application units of application systems, by rinsing the containers, Pipelines, pumps and other equipment, such as Application units of application system, with a cleaning agent found, which is characterized in that the detergent according to the invention used.
  • the cleaning agent used is a solution and / or dispersion of ingredients described below in water. According to the invention aqueous solutions are advantageous and are therefore preferred.
  • the cleaning agent contains essential to the invention Ingredient ammonia (a). According to the invention, this is in an amount of 0.015 to 0.75% by weight, based on the cleaning agent, contain. Even smaller amounts of ammonia can be used several cleaning steps are then necessary in individual cases. It more than 0.75% by weight of ammonia can also be used, however the advantages obtained by this no longer compensate in all cases increasing odor nuisance.
  • ammonia can be used as ammonia gas, as an aqueous, in particular 15% by weight Solution or in the form of salts, which when diluted with water Release ammonia, be added.
  • An example of a suitable salt this type is ammonium carbonate.
  • the other essential component of the detergent is at least one ethylene, propylene, diethylene and / or dipropylene glycol monoether (B). These are monoalkyl and / or monoaryl ethers (b), especially monalkyl ether (b).
  • C 1 to C 6 monoalkyl ethers preferably C 2 to C 4 alkyl ethers and / or C 4 to C 7 monocycloalkyl ethers, are advantageous according to the invention.
  • Examples of suitable monoalkyl ethers to be used according to the invention are ethylene, propylene, diethylene and / or dipropylene glycol monoethyl, -mono-n-propyl-, -mono-i-propyl-, -mono-n-butyl-, -mono-sec-butyl-, -mono-tert.-butyl-, -mono-n-amyl-, -mono-n-hexyl-, -mono-cyclobutyl-, -mono-cyclopentyl-, monocyclohexyl and / or monocycloheptyl ether.
  • Examples of highly suitable monoalkyl ethers to be used according to the invention of this type are the mono-n-butyl and the monocyclohexyl ethers, of which the Mono-n-butyl ethers are particularly advantageous and therefore according to the invention are preferably used.
  • Monoalkyl ethers of this type are ethylene glycol and diethylene glycol monobutyl ethers, of which whole ethylene glycol monobutyl ether (butyl glycol) is particularly advantageous and therefore very particularly preferred according to the invention is used.
  • the above-mentioned monoethers (b) to be used according to the invention are in the cleaning agent according to the invention in an amount of, based on the Detergent, 1 to 20 wt .-% contain. Smaller quantities can of the monoethers (b) to be used according to the invention, however this can make several cleaning steps necessary to remove residues have a comparatively low water solubility or dispersibility, reliably remove completely. It is also possible to use more than 20% by weight be applied. However, the problems which are generally associated with the use of organic solvents are no longer in all cases due to the advantages they bring about be compensated.
  • the quantity range is from 6 to 16% by weight Optimal, which is why these amounts are particularly preferably used. Outstanding results are achieved by using 10 to 14% by weight achieved. These amounts of monoethers (b) are therefore very particularly preferred applied.
  • the other essential component of the detergent is at least one defoamer (c).
  • defoamer (c) for use in the Detergents come basically all the usual and known defoaming agents available on the market.
  • the defoaming agents (c) are used in effective amounts, which the specialist on the basis of simple preliminary tests or on the basis of his specialist knowledge can determine. According to the invention, it is advantageous to use the defoaming agents (c) to be used in an amount of 0.001 to 0.5% by weight. Within this The quantitative range is the quantitative ranges from 0.004 to 0.4, preferably 0.006 to 0.3 and especially 0.008 to 0.15 wt .-% to emphasize because of the Using such amounts an optimal technical effect associated with the lowest possible consumption of defoaming agent (c) results.
  • the detergent can also contain other substances contained in effective amounts.
  • suitable substances are organic Amines such as ethanolamine or dimethylethanolamine, water-soluble cosolvents such as ketones, in particular acetone or methyl isobutyl ketone, or amides, in particular N-methylpyrrolidone or N, N-dimethylacetamide, or conventional and known additives such as wetting agents.
  • the cleaning agent is for the invention Method used. It is used according to the invention to remove Residues from containers and pipelines, such as those in the chemical Industry or in the paint industry usually for the manufacture of the Handling and use of substances can be applied. In particular serves it according to the invention the removal of residues from containers, Pipelines, pumps and other equipment, such as Application units of application systems, for coating agents, such as they are commonly used in the automotive industry for painting Automotive bodies are applied. In these application systems the coating agents in question up to their application in the Ring lines pumped over and exposed to strong shear forces, which is why here the risk of residue formation is particularly high. Is even higher the risk of residues forming in or on the Application units such as the high-speed rotary bells or the nozzles because here the coating agents are atomized, causing the solvents or the Dispersants can escape particularly easily.
  • the residues contain, which according to the inventive method components that are physically and / or thermally removed as well optionally coating agents, adhesives curable with actinic light or sealants come from.
  • these waterborne basecoats contain water-soluble or - dispersible binders, crosslinking agents, which with the binders react at elevated temperatures, as well as effect pigments and / or color pigments.
  • water-soluble or water-dispersible binders Polyurethanes are used, which in themselves are already physical are drying.
  • waterborne basecoats are known to be used for the so-called wet-on-wet process used in which after a short intermediate drying further Lacquer layers such as water-based lacquers and / or clear lacquers are applied, after which the applied layers are baked together.
  • Lacquer layers such as water-based lacquers and / or clear lacquers are applied, after which the applied layers are baked together.
  • waterborne basecoats which are special slightly physically dry. This will only apply dried water-based lacquer no longer by applying more Coating agent damaged. However, due to the slight physical drying the more residues on the application units form which the trouble-free wide coating of the automobile body makes impossible.
  • the method according to the invention can be used as often be repeated as necessary.
  • the method according to the invention surprisingly with far less Detergents and cleaning cycles come out as conventional methods.
  • the waterborne basecoats were each 3 ml of the essential to the invention used and the conventional cleaning agent drizzled. After that they were left Detergent each one minute without mechanical stress on the Apply water-based lacquer layers. After removing the detergent was the same spot on the waterborne basecoats as above described, drizzled again. This was repeated until there was a Removal and / or dissolution of the water-based lacquer layers at the drizzled areas came.
  • aqueous solution was used as the cleaning agent essential to the invention, which 0.075% by weight ammonia, 12.4% by weight butyl glycol and 0.02% by weight a commercially available defoaming agent (Surfynol®, from Air Products) contained.
  • An aqueous solution was used as a conventional cleaning agent, which is 4% by weight of dimethylethanolamine, 10% by weight of butyl diglycol and 0.01 % By weight of the above commercially available defoaming agent.
