Definitions

  • the invention relates to a two-layer, structure-borne sound absorbing and anti-corrosion, abrasion-resistant coating for rigid substrates, in particular for sheet metal in the underbody area of motor vehicles, which is also used to reduce noise caused by impacting particles.
  • Elastic structures such as thin sheets of vehicle bodies or machine housings, emit high levels of airborne sound at different frequencies under airborne sound excitation or structure-borne noise due to their inadequate damping. It is known to apply viscoelastic damping foils or coatings to the sound-emitting sheets for damping.
  • Another conceivable possibility would be to avoid the direct impact of the particles on the metal sheets in the underbody area of motor vehicles by applying suitable coverings to the sheet metal structure.
  • a covering would have to be as soft and thick as possible in order to provide a "long braking distance" for the approaching particles in terms of space and thus also time.
  • noise generation in particular in the higher-frequency, particularly disruptive frequency range.
  • a fundamental physical law, the Fourier transformation states that the behavior of a system in the time domain is strictly linked to the associated behavior in the frequency domain: the faster a process runs in time, the more higher frequencies are required to describe this process in the frequency domain. Short abrupt processes involve more high frequencies than longer, less abrupt ones.
  • the invention is therefore based on the object of developing a coating for rigid substrates, in particular for sheet metal in the underbody area of motor vehicles, including the wheel arches, which has a structure-borne sound-damping effect and is corrosion-resistant and abrasion-resistant, and which at the same time also leads to a substantial reduction in those caused by impacting particles Leads to noises. It is also essential that the coating has the desired properties practically unchanged over long periods of time.
  • the inner layer is foamed, which both increases its softness and increases its layer thickness.
  • the inner layer has a layer thickness that is 2 to 20 times greater than that of the cover layer.
  • the modulus of elasticity of the inner softer layer should generally be ⁇ 108 dynes / cm2.
  • the weight per unit area of the coating as a whole is preferably less than that of the substrate.
  • a coating that meets the requirements mentioned above must at the same time be very soft and as thick as possible so that it can effectively stop the impacting particles. Furthermore, it should show the best possible effectiveness as a structure-borne sound deadening material. For practical use, however, it is also essential that the coating offers good corrosion protection and, above all, shows high abrasion resistance. This is particularly true in the area of the wheel arches. High softness and good abrasion resistance are mutually contradictory requirements, which are however met by the two-layer coating according to the invention.
  • the layer arranged on the sheet metal side is softer and relatively thick, so that it is the posed acoustic conditions met. Their thickness is generally in the range from 1 to 5 mm.
  • the cover layer is thinner and relatively tough-elastic, so that it ensures abrasion resistance. A thickness in the range of 0.25 to 1 mm is preferred.
  • Example 1 arylalkyl sulfonate is used as the plasticizer for the inner layer, which is combined with polyvinyl chloride, the polymer of the outer layer is compatible, so that a softening of the top layer occurs due to plasticizer migration.
  • the identical plasticizer is used in different concentrations for both layers, which also leads to migration of the plasticizer due to the concentration gradient.
  • plastisols are used, such as have been used in automotive construction for some time as underbody protection, weld seam sealing, adhesives and the like, and as is already known in principle from DE-PS 28 52 828.
  • the coating can be applied particularly advantageously in such a way that the two layers are formed in successive spraying processes (wet-on-wet application), with the gelation of the layers taking place simultaneously and together by a subsequent heat treatment.
  • the mixture is heated to about 100 to 180 ° C. for 10 to 60 minutes.
  • the required different softness of the layers is achieved either by a higher plasticizer content in the inner layer and / or by foaming the inner layer.
  • Particularly suitable polymers for the plastisols are powders of polyvinyl chloride homo- and / or copolymers, e.g. with vinyl acetate. Also suitable are powders of (meth) acrylate homo- and / or copolymers, as described in DE-PS 24 54 235 and 25 29 732. So-called core / shell acrylic polymers according to DE-AS 27 22 752 can also be used with advantage.
  • plasticizers such as phthalates, phosphates, adipates and citric acid esters are known for polyvinyl chloride homopolymers and copolymers.
  • Dialkyl phthalates such as e.g. Diocytl phthalate and dinonyl phthalate because they are incompatible with (meth) acrylate homo- and copolymers.
  • dibenzyl ether, dibenzyl toluene, diphenyl methane and diphenyl ether are particularly suitable as plasticizers because, in turn, they are not compatible with vinyl chloride homo- and copolymers.
  • Arylalkyl sulfonates are compatible with both groups of polymers, so that they can only be used if the plasticizer concentration in both layers is essentially identical.
  • the mechanical properties of the layers can be influenced in a manner known per se by adding inorganic fillers.
  • Suitable fillers are, for example, calcium carbonate and oxide, barium sulfate, carbon black, graphite, titanium dioxide, talc and organic or inorganic hollow spheres.
  • the plastiol for the production of the inner softer layer had the following composition: Polymethyl-n-butyl methacrylate (with 2% vinylimidazole) 20% Dibenzyltoluene 50% Calcium carbonate 28% Calcium oxide 2%
  • 1% azodicarbonamide was optionally added to produce foamed layers.
  • a plastisol of the following composition was used for the top layer: Polyvinyl chloride (K value 70, paste type) 30% Dinonyl phthalate 30% Calcium carbonate 38% Calcium oxide 2%
