Definitions

  • the invention discloses a cleaning agent for removing gray haze on glass sheets and a method for cleaning glass sheets.
  • Extensive glass facades are nowadays an indispensable part of the streetscape of most major cities.
  • modern skyscrapers and "skyscrapers” are equipped with a high proportion of glass panes.
  • glass panels generate additional care and maintenance. Cleaning and maintenance of the glass façade is a work and cost factor that should not be underestimated when maintaining the building.
  • Glass panes are subject to many and many types of soiling. Dust, sand, pollen, moisture, rain and insects produce various and sometimes quite resistant coverings. The incident light is scattered or absorbed by these soiling and thus produces clearly visible clouding or light reflections for the human eye. This greyish coating significantly reduces the optical quality of the window pane as a gray haze.
  • the dirt film can also limit the technical and functional properties of the disc. For example, a coating of catalytic TiO 2 for self-cleaning properties relies on UV light. However, the available amount of UV light is significantly reduced by the dirt film. In addition, the dirt film can block the contact points necessary for the catalytic action of the TiO 2 .
  • glazing itself is a frequent cause of contamination.
  • the linking of monomers or the crosslinking of the polymer chains within the sealant releases in many cases organic solvents, water or even acids or bases.
  • organic solvents are Alcohols or polar amines.
  • These liquid components can also distribute smaller parts of the gasket on the glass surface.
  • These components, such as silicones may then develop into a greyish, solid and stable coating (gray haze) or precipitate along with dust from the outside air.
  • the cleaning of the individual windows is very time-consuming and expensive.
  • GB 1 509 199 A discloses a cleaning solution or suspension for the cleaning of glasses and windshields with a (ionic) anionic surfactant, an organic carboxylic acid, and optionally a carboxylic acid salt, phosphoric acid and a fluorinated surfactant.
  • EP 0 673 992 A2 discloses a concentrated cleaning solution for glass and window cleaning.
  • the cleaning solution contains 10% by weight to 75% by weight of glycol ether solvent and 0.1% by weight to 20% by weight (non) anionic surfactant.
  • a preferred composition contains sodium methyloleoyl taurate and dioctyl sodium sulfosuccinate surfactant and a mixture of ethylene and propylene glycol monoalkyl ethers as solvents.
  • US 5,342,549 A discloses a cleaning solution for removing stubborn deposits on hard and smooth surfaces such as glass.
  • the cleaning solution contains a beta-based amphoteric surfactant and, in a preferred embodiment, a polar organic solvent.
  • US 3,915,738 A discloses a cleaning solution for removing foreign substances from glass surfaces.
  • the cleaning solution contains a catalyst of sodium silicates and Alkaline earth ions in collodially dissolved form.
  • the cleaning solution contains further surfactants.
  • the object of the present invention is to provide a cleaning agent which allows a reliable cleaning of the glass sheet of gray haze while preventing re-soiling over as long a period as possible.
  • the cleaning agent according to the invention for removing gray haze on glass panes from a suspension comprises at least 20% by weight to 50% by weight of aluminum oxide (Al 2 O 3 ), 0.01% by weight to 5% by weight of nonionic surfactant and 0.01% by weight. % to 5% by weight of complexing agent.
  • the remaining quantities are made up with water, preferably deionized water.
  • the nonionic surfactants improve, optionally together with another nonionic or ionic surfactant, the suspension stability of the aluminum oxide and at the same time can dissolve organic, in particular greasy, soiling from the surface of the pane.
  • the alumina has an average particle size of 100 nm to 800 nm.
  • the mean particle size of Al 2 O 3 is preferably between 200 nm and 600 nm.
  • the particle size of Al 2 O 3 according to the invention in the cleaning agent according to the invention makes it possible to clean the surface of the disc from grayscale without damaging the glass surface.
  • the term "suspension" for the purposes of the invention also includes dispersions. Heavy metals and alkaline earth ions in the soil can be bound and removed via complexing agents contained in the suspension.
  • the pH of the suspension according to the invention is preferably in the range of pH 6 to 8.
  • the cleaning agent according to the invention not only enables easy removal of the gray scale and other stains, but also surprisingly prevents the new staining of the glass pane over a long period of time.
  • the suspension preferably contains ionic surfactants, particularly preferably anionic surfactants, more preferably alkylcarboxylates, alkylbenzenesulfates, alkanesulfonates, fatty alcohol sulfates, fatty alcohol carboxylates, more preferably sodium lauryl sulfate (SDS), sodium dodecylpolyoxyethylene sulfate (SLES) and / or dioctyl sodium sulfosuccinate (AOT).
  • ionic surfactants particularly preferably anionic surfactants, more preferably alkylcarboxylates, alkylbenzenesulfates, alkanesulfonates, fatty alcohol sulfates, fatty alcohol carboxylates, more preferably sodium lauryl sulfate (SDS), sodium dodecylpolyoxyethylene sulfate (SLES) and / or dioctyl sodium sulfosuccinate (AOT).
  • the nonionic surfactants preferably contain alkyl polyglycol ethers, aryl polyglycol ethers, alkylpolyglycosides (sugar surfactants) and / or sorbitol glycol ethers.
  • the suspension preferably contains 0.1% by weight to 3% by weight of nonionic surfactants.
  • nonionic and ionic surfactants can further enhance the efficiency of the suspension.
  • the sensitivity of the suspension to pH and salt concentration fluctuations is reduced.
  • the suspension preferably contains glycols, more preferably ethyl glycol, propyl glycol, butyl diglycol, propylene glycol, and / or mixtures thereof.
  • glycols more preferably ethyl glycol, propyl glycol, butyl diglycol, propylene glycol, and / or mixtures thereof.
  • the suspension preferably contains 0.01% by weight to 5% by weight of glycols.
  • the suspension preferably contains 30% by weight to 45% by weight, particularly preferably 32% by weight to 42% by weight, of aluminum oxide (Al 2 O 3 ).
  • Al 2 O 3 aluminum oxide
  • the abrasive action of the alumina also allows the mechanical removal of solid residues on the disc. If the weight proportions of the aluminum oxide deviate from the ranges according to the invention, the cleaning performance deteriorates at low concentration. If the concentration of alumina is higher than disclosed in the invention, the suspension stability decreases and the disk may be damaged during cleaning.
  • the suspension preferably contains preservatives and / or antioxidants, preferably ascorbic acid and / or benzoic acid.
  • the suspension preferably contains water softeners and / or defoamers, particularly preferably alcohols, polydimethylsiloxanes, phosphates or aluminum silicates, particularly preferably zeolites and / or sheet silicates. These additives increase the stability of the suspension in terms of cleaning efficiency and temperature stability. Phospate or Aluminum silicates bind alkaline earth ions which significantly limit the effectiveness of surfactants, especially ionic surfactants. Alcohols or polydimethylsiloxane reduce foaming, which can complicate the actual cleaning process.
  • the suspension preferably contains 0.1% by weight to 3% by weight of complexing agent, particularly preferably ethylenediaminetetraacetic acid (EDTA), oxalic acid, tartaric acid, succinic acid, ethylenediamine, acetylacetone and / or nitrilotriacetic acid (NTA).
  • complexing agent particularly preferably ethylenediaminetetraacetic acid (EDTA), oxalic acid, tartaric acid, succinic acid, ethylenediamine, acetylacetone and / or nitrilotriacetic acid (NTA).
  • the suspension preferably contains antislip agents, preferably ethanol, isopropanol and / or ammonia.
  • the invention further comprises a method for removing stains on glass panes, wherein in a first step, a cleaning agent according to the invention is applied to a cloth or directly onto a pane to be treated.
  • cloth also includes leather cloths, cloth towels, cellulose cloths, sponge cloths, sponges and cotton balls for the purposes of the invention.
  • the slices may be pre-cleaned with water and a small amount of household cleaner prior to application of the suspension.
  • the disk is wiped with the cloth and the cleaning agent according to the invention evenly distributed on the disc.
  • the disc is wiped with a clean side of the cloth or a new cloth and the resulting film recorded.
  • the pane preferably comprises single-pane safety glass (ESG), laminated safety glass (LSG) or insulating glass.
  • the pane preferably comprises hydrophilic or hydrophobic coatings, preferably coatings containing TiO 2 .
  • TiO 2 forms hydrophilic transition states that significantly improve the self-cleaning and drainage of fluids from the disk. These increase the contact angle of polar liquids such as water on the surface of the disks and thus increase the wetting of the surface. The liquid runs off as a flat film faster and thus cleans the surface. Additionally, TiO 2 can catalyze the decomposition of soils improve. Examples of such coatings are also disclosed in the patent applications EP 0 850 204 A1 and EP 0 927 144 A1 disclosed.
  • the cleaning agent is preferably rubbed on the surface of the disc.
  • the trituration allows a reinforcing abrasive effect of the cleaning agent according to the invention, in particular of the Al 2 O 3 contained in the suspension.
  • the concentration of aluminum oxide can be varied.
  • the cleaning agent is preferably taken up after rubbing with a puller, cloth and / or sponge.
  • the disk is preferably pre-cleaned before applying the cleaning agent.
  • the pre-cleaning can be done with water, preferably deionized water.
  • a nonionic and / or ionic surfactant further improves the cleaning performance of the process according to the invention.
  • nonpolar organic impurities such as fats can be dissolved or dissolved from the disk surface.
  • the invention further includes the use of the cleaning agent according to the invention for cleaning glass, plastic or metal surfaces.
  • Example 1 Two adjacent conventional insulating glass panes were examined on the side facing the weather after the treatment with the cleaning suspension according to the invention (Example 1) and without cleaning suspension according to the invention (Example 2) on emerging gray haze.
  • the disk was then wiped several times with the Terry cloth.
  • the resulting slightly whitish film was then wiped with a clean tissue cloth and removed.
  • the pane shows no visible stains or streaks in transmitted light and reflective light.
  • the immediate area of the seal, in particular rubber or silicone seals, is not treated with the cleaning agent according to the invention.
  • Example 1 was cleaned with the cleaning agent according to the invention. Both discs in Example 1 and Example 2 show no visible contamination at the beginning of the experiment. After 14 days on the disc in Example 2 are clear Stains, while the disc in Example 1 shows no signs of staining even after more than 14 days. These results were surprising and unexpected to those skilled in the art.
