Definitions
- the invention relates to an apparatus and a method for preserving components with a preservative.
- the invention finds application in preserving hard-to-reach areas to be preserved, e.g. cavity seals, seam seals (e.g., bead seams), etc. of automotive body components.
- the cavity preservation i. the preservation of an inner surface of a cavity, is usually used in high-quality vehicles to extend the corrosion protection significantly.
- the use of cavity preservation is typical in particular in countries in which high promises concerning the so-called "rust-through guarantee" (corrosion protection guarantee) are made, which applies in particular to many countries in Europe Some vehicles imported into such countries become, unless they have already been subjected to a cavity preservation , subsequently subjected to a cavity preservation.
- the cavities to be preserved of the vehicle body are filled with solvent-free and liquefied by heating wax, wherein a portion of the wax deposited on the cavity walls and thereby preserved, while the excess wax expires.
- the wax serving as the preservative is sprayed on the inner walls of the cavities, for example, by using an application pipe (lance) inserted into the cavities from the outside and having outlet openings for the wax.
- a wax is usually used as a cavity preserving material.
- processing is typical in which the wax is pre-atomized together with air in a pre-atomizing chamber and directed by air through hoses (e.g., 3-8m in length) to the body. The air is used for atomization, transport and distribution in the cavity.
- the wax is introduced into the cavity and is usually intended to seal it. It has to get lost. This is mostly assisted by a tilt station that "tilts" the body panel to aid in wax penetration, and openings (spouts) in the body part to be preserved indicate that the cavity is successfully coated.
- This disadvantage is minimized by providing a wax dryer.
- This wax dryer heats the bodywork le to a certain minimum temperature over a certain minimum time, eg 1 min. at 60 ° C.
- a usual wax dryer length is for example 60 m. After the drying process, the leakage of wax is substantially stopped.
- the so-called "drop-stop" is used, but the wax hardens for a few days / weeks, but never solidifies, but remains flexible.
- Wax dryers suffer from a number of disadvantages, such as high energy consumption during operation , high investment and / or maintenance costs, high cleaning effort, large space consumption, lack of retrofitting for many customers, etc.
- the object of the invention is to provide an improved device and an improved method for the preservation of components.
- the invention comprises the general technical teaching of mixing a preservative and a hardener in the preservation of components in order to cut the preservative. ler harden, in particular, to achieve a "drop stop".
- the device according to the invention for the preservation of components with a preservative is characterized in particular by applying, in addition to the preservative, a hardener which reacts with the preservative in order to cure the preservative.
- the device is thus preferably provided to additionally apply a hardener to the preservative to react with the preservative, whereby a hardening of the preservative can be achieved.
- a further advantage of the invention is that the device can be designed so that no or only very few sections of the device come into contact with a mixture of preservative and hardener.
- the preservative cures through the hardener from the ischvorgang.
- a conventional mixer can not sit directly in the nozzle for reasons of space, but would have to be cultivated a few inches to a few meters from the nozzle. Since the hardener reacts with water, the water or the residual moisture from the air / compressed air is sufficient to initiate a reaction. As a result of the process of empty blowing of the feed line after pre-atomizing and / or mixing, residues would remain in the feed line which would no longer be completely discharged even in subsequent coating operations.
- the mixing of preservative and hardener may preferably be carried out fluidically at an end portion of the device, such as in an application device, an application element and / or a nozzle. It is also possible to design the device so that the preservative and the hardener mix in flight (in the air), in a cavity to be preserved and / or on a component to be preserved.
- the initiation of the mixing is thus preferably carried out in an application device, an application element, a nozzle, in flight (in the air), in a cavity to be preserved and / or on a component to be preserved.

- the mixing process can thus be initiated in the application element.
- preservative line and the hardening line lead into the first application element in such a way that the preservative and the hardener mix immediately before the first nozzle and / or in the first nozzle.
- the mixing process can thus be initiated immediately before the first nozzle and / or in the first nozzle.
- a second outlet opening can be provided on the first nozzle.
- the first application element may further comprise a second nozzle, on which a second outlet opening is provided.
- the preservative line preferably leads to the first outlet opening and the hardener line leads to the second outlet opening so that the preservative and the hardener mix in the flight and / or on the component to be preserved.
- the mixing process can thus be initiated fluidically behind the outlet openings.
- the preservative and the hardener mix in the flight and / or on the component to be preserved.
- the advantage of this is that no internal sections of the device come into contact with a mixture of preservative and hardener.
- the application device has a second application element with at least one second outlet opening.
- the first and second application elements are two separate parts that are independently movable and / or controllable, e.g. one after the other in a cavity to be preserved can be performed.

- the preservative agent application station and the curing agent application station may preferably be provided parallel to a conveying path for motor vehicle body components to be preserved.
- the second application element may have a second nozzle, on which a second outlet opening is provided.
- the preservative conduit leads to the first exit port and the hardener conduit to the second exit port so that the preservative and the hardener mix in the flight and / or at the area to be preserved.
- the mixing process can thus be initiated fluidically behind the outlet openings.

- the first and / or second application element may preferably be an application tube, a lance, a probe, etc.
- the first and / or second outlet opening is preferably provided on these elements, preferably on a nozzle.
- the application element is designed, for example, such that it can be guided through an opening into a cavity to be preserved in order to spray its interior surfaces to be preserved with preservative and / or hardener.
- a mixer in particular in the application device, an application element, preferably an application tube, and / or in a nozzle.
- the mixer may also extend over at least two of the aforementioned portions (eg, from the application tube to the nozzle).
- the mixer must be correspondingly small in size, and still achieve sufficient mixer results, which conventional mixers are not able.
- a suitable for the invention The mixer could preferably be produced by means of generative methods (eg rapid prototyping).
- means may be provided, in particular the application device, the application element and / or the first and / or second nozzle with a solvent / rinsing agent, a reactive substance (eg a reaction retarder, such as an organic acid chloride), the curing substantially stops or inhibits, and / or a monofunctional substance (eg, propanol or butanol, especially in the case of an isocyanate functionality) that reacts with the preservative and / or the hardener to substantially stop or inhibit curing (in particular, by whose chain reaction is substantially suppressed), to flow through, to coat and / or to fill.
- a reactive substance eg a reaction retarder, such as an organic acid chloride
- a monofunctional substance eg, propanol or butanol, especially in the case of an isocyanate functionality
- the reactive substance and / or the monofunctional substance thus act as a blocking agent to retard, preferably substantially prevent, curing of the preservative or mixture comprising preservatives and hardeners. It is possible that the mixture may contain other ingredients, e.g. a dissolving and / or rinsing agent comprises.
- the monofunctional substance is preferably a reactive, monofunctional substance which reacts with a preservative component and / or a hardener component, preferably with a hardener component, but does not lead to polymer chains due to its monofunctionality, but ideally to a Molecule or oligomer from a hardener molecule and two blocking agent molecules.
- Suitable monofunctional substances are, in particular, amines or alcohols, preferably lower alcohols, such as, for example, ethanol, propanol, butanol and / or their isomers.
- the reactivity of the chain reaction, which is determined by the mo- nofunctional substance is substantially suppressed, should be higher than that of the chain-forming reaction. Because, for example, the bi- or multifunctional hardener molecules react with a short-chain monofunctional molecule, the viscosity of the mixture (preservative, hardener, monofunctional substance) remains low.
- the reactive substance should not enter the cavities to be preserved.
- the invention opens up the possibility of designing the device such that the preservative and the hardener can be mixed in the device, in the application device, in an application element, in a nozzle, outside the application device, outside an application element , outside of outlet openings, in flight (in the air) and / or on the component to be preserved.
