Definitions

  • the present invention relates to a method for cavity sealing of a motor vehicle component, comprising the following steps:
  • the present invention further relates to a composition for producing a cavity seal, as well as a motor vehicle component having a cavity seal.
  • various structures formed from metal sheet are connected to form larger components.
  • these components are electrochemically coated after assembly with a paint layer.
  • a Faraday cage In areas where two metal parts come close to each other or in which by bending parts of a single metal part close to each other, there is the formation of a Faraday cage and therefore no or at least insufficient deposition of the paint.
  • a cavity seal is applied there from a cavity preservative.
  • One method of making such a cavity seal involves spraying a cavity preservative into the automotive components to be protected, permitting the cavity preservative to penetrate, draining excess cavity preservative, and curing the cavity preservative in the motor vehicle component being protected.
  • the cavity preservative should always be used to some extent in excess. To ensure that the cavity preservative can penetrate into small cracks and niches of a motor vehicle component, this must have a high flowability.
  • the cavity preservative After applying the cavity seal, it is desirable for the cavity preservative to solidify quickly so that the automotive components can be processed quickly without dripping cavity preservative in later processing. Such erosion of cavity preservative leads to contamination in the further processing of the motor vehicle components as well as to a risk of workers being able to slip on it.
  • cavity preservatives which are rendered flowable by the addition of volatile solvents and which solidify due to evaporation of the solvent is undesirable these days due to the associated environmental impact and OSH expenses, as well as potential exposure of the vehicle owners to subsequent solvent evaporation.
  • the object is achieved by a method for cavity sealing of a motor vehicle component in which the cavity preserving agent has a crosslinkable component and in which step a.) Precedes the step of admixing a crosslinking component, wherein the amount and type of crosslinkable component and the crosslinking component are chosen so that the cavity preservative between step c.) And d.) Solidifies to a gel-like consistency.
  • the object is achieved by a composition for producing a cavity seal having a cavity preserving agent and a solidifying agent, wherein the cavity preserving agent comprises a crosslinkable component, wherein the solidifying agent is a crosslinking component and wherein the amount and type of crosslinkable component and crosslinking component are selected such that the cavity preservative solidifies to a gelatinous consistency within a predetermined time period.
  • the cavity preserving agent comprises a crosslinkable component
  • the solidifying agent is a crosslinking component and wherein the amount and type of crosslinkable component and crosslinking component are selected such that the cavity preservative solidifies to a gelatinous consistency within a predetermined time period.
  • the object is achieved by a motor vehicle component having a cavity seal, which can be produced by the method according to the invention.
  • a crosslinkable component can be admixed with a cavity preservative and this can then be crosslinked by adding a suitable amount of a crosslinking component, so that a gel-like consistency of the cavity preservative is achieved, which reliably prevents unwanted dripping.
  • the time required for this system to gel is set so that the cavity preservative is sprayed as a liquid and penetrate into the cracks and niches to be sealed and so long desired to drip from the automotive components. After this time, solidification takes place, which reliably prevents further dripping. Furthermore, the fact that there is a period between spraying and gelation in which the cavity preserving agent remains liquid, also clogging of the spray nozzles by solidified cavity preservative can be avoided.
  • the addition of the crosslinking component to the cavity preservative may in this case take place directly before the injection of the cavity preservative or already during the preparation of the cavity preservative.
  • the corresponding composition for producing the cavity seal is generally in the form of a 2-component system.
  • the cross-linking component eg in the form of atmospheric moisture
  • the composition is present as a one-component system.
  • the composition for forming a cavity seal is in the form of a one-component system and further comprises means for suppressing the reaction between the crosslinkable component and the crosslinking component.
  • reaction suppression agents are selected to be eliminated from the composition shortly before or during spraying (e.g., by evaporation or reactive degradation) and thus the desired reaction occurs between the crosslinkable component and the crosslinking component.
  • the crosslinking reaction leading to the formation of the gel-like structure proceeds at about room temperature, heating of the automotive component to solidify the cavity preservative and thus to achieve the drop-stop effect is no longer necessary.
  • no large heaters are needed for the method of the invention, and such a method can be used in any device designed to apply a cavity seal.
  • the method according to the invention also works without great expenditure of energy, e.g. for heating the motor vehicle component.
  • the cavity preservative may be any commercially available cavity preservative which either contains a crosslinkable component from the beginning or to which a crosslinkable component is admixed.
  • such cavity preservatives include ingredients such as anti-corrosion additives such as calcium sulfonate, oxidatively crosslinking binders such as alkyd resins, flexibilizers such as mineral oils or esters, fillers such as talc, rheological additives such as inorganic thickeners such as bentonites, organic or inorganic Bases that also contribute to corrosion protection, such as triethylenediamine, catalysts for oxidativc curing of the binder, such as manganese salts and other additives, for example, to prevent the formation of a skin during standing, such as 2-butanone oxime on.
