Definitions
- the invention relates to a barrier liquid for waterless operated sanitary facilities based on an oil.
- liquids In order to avoid unpleasant odors in waterless, sanitary facilities, liquids have been developed which close the air space above a drainage pipe or siphon.
- the liquids serve as a barrier medium and as an odor trap for the mouth of the outlet pipe, in order to prevent odors from the sewer system can rise in the sanitary interior.
- the document discloses an odor trap for a siphon containing a glycerol based fluid. Although this has the advantage that odors from the siphon can no longer escape into the ambient air of a sanitary system. However, this takes place only until the glycerol used has mixed with the aqueous constituents of the urine and / or a reaction of glycerol with constituents of the urine has not occurred. If a reaction with the constituents of the urine, so deposits can form within the siphon, which grow into layers and the
- Blocking the siphon can lead and in addition to the cleaning of the siphon soon require a renewal of glycerol.
- ethylene glycol as a barrier liquid in toilets and urinals from DE 28 214 79 B1 is known.
- ethylene glycol which is used in automotive engineering as brake fluid and antifreeze for cooling water, is toxic.
- the contact of a user or a cleaning person with such a kind of barrier liquid can lead to poisoning or chemical burns.
- JP 2009-127355 A is a water evaporation inhibitor for
- Dewatering systems such as sanitary facilities, which may contain a water-insoluble component such as paraffin oil, especially white oil, and a density of less than 1, 0 and has a vapor pressure lower than water.
- the water-insoluble component comprises from 1 to 99% by weight and may additionally contain dyes, fragrances, pigments and also surfactants.
- WO 2010/001595 A1 discloses a barrier water for pipelines in bathrooms and toilets for preventing malodors, which comprises oil, water and a surfactant.
- the oils described can be designed as liquid paraffin oil, wherein the surfactant contained
- JP 2005-118519 A describes a liquid for sealing
- Containers such as WCs, which consist of liquid paraffin and may have additives.
- additives Fe 2+ , titanium dioxide or
- Activated carbon called to prevent odors and to achieve an optical effect.
- barrier fluids such as, for example, oils which are immiscible with the wastewater and have a density which is lower than that of the wastewater.
- Blocking liquids are known from DE 10 2010 033 798 A1 which comprise oils or oil mixtures and preferably contain antimicrobial, bacteriostatic to bactericidal and / or odor-absorbing additives.
- WO 2005/024146 A1 discloses barrier fluids as
- Odor trap of waterless urinals whereby the barrier liquids may also contain fragrances.
- the barrier liquids may also contain fragrances.
- the object of the invention is therefore to provide a barrier fluid for waterless toilets or urinals, on the one hand the best possible
- Odor trap of the siphon against sewage channels offers and on the other hand hardly needs to be replaced or renewed.
- the barrier liquid contains an oil containing a paraffin oil with a content of unsaturated and / or aromatic hydrocarbons of less than 1 percent by weight and the paraffin oil has an addition of antibacterial substances and / or silica particles.
- the barrier liquid Compared to known barrier fluids based on an oil occur in the barrier liquid according to the invention, on the one hand virtually no deposits in the siphon of waterless sanitary facilities on the other hand, in the event that deposits should occur by these or additives inodorent and physiologically harmless. Furthermore, the urea derivatives and proteins contained in the urine can be removed by the one or more additives from the barrier liquid, so that no odor-intensive compounds come to the outside and deposits, for example in the form of those contained in the urine proteins can be removed from the barrier liquid again.
- Suitable silver compounds are all antibacterially active silver compounds such as silver ions, in particular in the form of silver nitrate, silver sulfate, silver chloride, silver chlorate or organic silver complexes such as silver chelates. These will be the
- Barrier liquid is added to the setting of the desired concentration range, which can be selected depending on the antibacterial effect.
- the barrier liquid may also contain an addition of silica gel particles which may alternatively or cumulatively be contained with the silver compounds in the barrier liquid.
- the silica gel particles can be any silica gel particles which may alternatively or cumulatively be contained with the silver compounds in the barrier liquid.
- the silica gel particles can be any silica gel particles which may alternatively or cumulatively be contained with the silver compounds in the barrier liquid.
- the proteins contained in the urine can be adsorbed on the silica gel particle solid phase, wherein the separation of the adsorbed proteins by applying a magnetic field takes place.
- the separation of the proteins bound to the silica gel particles from the barrier liquid can also be effected by means of pressure, gravitational or centrifugal force.
- the silica gel particles can be present as isolated spherical particles, as monolithic silica gel phases or as membranes.
- the silica gel particles generally have a diameter in the range from 20 nm to 500 ⁇ m, preferably from 200 nm to 10 ⁇ m, in particular from 500 nm to 1.3 ⁇ m.
- the adsorbent of silica gel particles having a magnetic core can be prepared by coating particles containing iron oxide with silica gel.
- the coating of iron oxide-containing particles with silica gel for the process according to the invention can be carried out, for example, as follows become:
- a suspension of iron oxide-containing particles in an alcohol e.g., isopropanol
- an alcohol e.g., isopropanol
- ammonia for coating with tetra-ethyl-orthosilicate (TEOS).
- TEOS tetra-ethyl-orthosilicate
- Coating can be controlled by the amount of tetraethyl orthosilicate added.
- the coated iron oxide-containing particles are washed with an alcohol (e.g., methanol) and stored in water.
- an alcohol e.g., methanol
- silica gel particles which consist of a mesoporous layer which is applied to the magnetic core and has a layer thickness in the range from 10 to 100 nm are particularly preferred.
- Magnetic cores for the silica gel particles according to the invention may be per se known particles of iron oxide (Fe 2 O 3) and silicon dioxide, polystyrene and / or polyvinyl alcohol.
- Iron oxide particles having a mesoporous silica gel coating, as produced in the presence of polyethylene glycol as a porogen, are preferably used for the process according to the invention.

- Hydrocarbons having a chain length of C20 to C30.
- Insulating liquid according to the invention thus only has an amount of less than 1 percent by weight of unsaturated and / or aromatic hydrocarbons and only a proportion of sulfur compounds of less than 65 mg / kg. Because of this chemical structure is the
- the barrier fluid according to the invention is represented by 0 2 and Urine components are not oxidized and other chemical reactions are not or only to a very limited extent. This leads to a consumption of the barrier liquid according to the invention in waterless sanitary facilities practically not done, as by the long-chain, saturated structure of the paraffin oil oxidation resistance to the outside air and a reaction inertness of the barrier liquid with fecal components such
- a reaction with uric acid will not take place or only to a very limited extent. Due to the inertness of the barrier liquid used virtually no reaction products are formed, which can lead to deposits in the siphon of waterless sanitary facilities such as toilets and urinals. In the event that some of the compounds remaining in the urine cause reactions, on the one hand odor nuisance and a microbial load can be avoided by the additives according to the invention and on the other hand a removal of the existing proteins can be made possible.
- the barrier liquid remains durable in its structure so far and allows a long-lasting, non-renewing, sealing closure of the siphon to the outside environment.
- the barrier liquid according to the invention may further comprise a paraffin oil in the form of a white oil, which except for supplies such.
- a paraffin oil in the form of a white oil which except for supplies such.
- Silver compounds in the form of silver nitrate, tocopherol, and / or silica gel particles has no additives. Due to the possible, but only very small share of
- Silver compounds in the barrier liquid is also not sustainable
- Hydrocarbons with a chain length of C20 to C30 has the
- sealing fluid according to the invention has a melting point which ensures a liquid state of matter to below -10 ° C. This is important because waterless sanitary systems are also used in areas where the ambient temperature is below 0 ° C.
- Registered urine components remain so in a range of 0 ° C to - 20 ° C dissolved and not not on the surface of the barrier liquid. Also by the high boiling range of 350 ° C to 460 ° C with a vapor pressure in a range of ⁇ 0.1 hPa at ordinary room temperatures
- the barrier liquid according to the invention is hydrophobic due to its chemical property and has a density in a range of 600 to 1000 kg / m 3, preferably 700 to 900 kg / m 3, a lower density than water.
- This allows the passage of urine components in the use of waterless sanitary facilities such as toilets and urinals and ensures a sealing completion of the opening into the sewer siphon to the outside environment.
- an overlay of the aqueous phase with the barrier liquid according to the invention so that a reaction with secondary products of the aerobic, bacterial decomposition of uric acid to NH 4 OH can not take place. The consequence is that both odor pollution in the
- the barrier fluid according to the invention may have a straight-chain or even branched structure, wherein the use of the straight-chain or branched structure is based on the intended use of the barrier fluid.
- the flash point of the proportion of the barrier liquid according to the invention is above about 200 ° C and the auto-ignition takes place only in a range above 320 ° C to 360 ° C.
- Unsaturated compounds such as unsaturated vegetable oils, when dispersed on a large surface area, can generate sufficient heat by direct oxidation with atmospheric oxygen to provide adequate heat
- the barrier liquid according to the invention offers a guarantee that oxidation by atmospheric oxygen and corresponding heat generation do not take place. Since the oxidizing ability of substances generally increases with increasing temperature, can by the use of the barrier liquid according to the invention with their proportion of unsaturated hydrocarbons in a range of less than 1
- barrier liquid according to the invention in a particular embodiment, an additional proportion of an additive, which has a solubility of at most 0.001 weight percent in the barrier liquid.
- Sperrten is located in the toilet or urinal basin.
- an additive is added to the barrier liquid according to the invention to give an indication as an indicator by a color change, if a removal of urine registered proteins from the Sperrfiüsstechnik should take place.
- the additive can be
- biuret reagent for example, biuret reagent or ninhydrin.
- ninhydrin for example, biuret reagent or ninhydrin.
- Solubility of the additive in the paraffin oil according to the invention has the advantage that only a very small amount of an additional substance is needed for the barrier liquid and thus a strong contamination of the paraffin oil according to the invention is prevented. This minimizes any unwanted reaction of the body to foreign substances, such as an allergic or irritating reaction, to any person in contact with the barrier fluid.
- the additive may be colored blue or green in a particular embodiment. Blue or green paint is associated with toxic cleaning agents or disinfectants in the cleaning industry.
- the barrier fluid according to the invention may contain an additive as additive in the form of a surfactant. Such can be added to the barrier liquid to
- the surfactant can be made biodegradable.
- the barrier liquid as an additive to add a fragrance, such as a perfume. This is usually done for the sake of
- Odor design In the barrier fluid according to the invention, all known lipophilic fragrance or perfume substances can be solved.
- the change in the perception of odor users sanitary facilities such as toilets or urinals can experience depending on the fragrance and fragrance concentration a stronger or weaker expression, so that both a very intense and very subtle odor design can be selected.
- the proportion of the perfume as an additional constituent of the barrier fluid according to the invention is in a range from 0.05 to 0.15
- a further embodiment of the present invention of the present invention is the use of the paraffin oil according to the invention with a content of unsaturated and / or aromatic hydrocarbons of less than 1 percent by weight and a melting point in a range of -10 to -20 ° C, a boiling range of 350 ° C up to 460 ° C and one
- paraffin oils having a viscosity in a range of 20 ° C to 100 ° C with a viscosity of 50 mm 2 / s to 4 mm 2 / s and an average density in the range of 600 kg / m 3 to 1000 kg / m 3 as
