Definitions

  • the subject of the present industrial property right is an electrically conductive floor construction, consisting of a customary usable floor, which has a textile or plastic covering as the top layer and which combines good heat insulation with pleasant elastic accessibility.
  • a floor structure is known in which a foundation or leveling layer is applied to a screed on a screed.
  • this compensation layer there is an electrically conductive layer, on which in turn a plastic top layer containing aluminum powder is applied as a useful covering.
  • the property of its electrical conductivity of a useful covering comes more and more to the fore.
  • the walker is electrostatically charged, especially in dry air.
  • this electrostatic charge can lead to unpleasant discharges if the person walking on the floor touches electrically conductive objects and, in addition, also leads to malfunctions in running computer programs or even ignites explosive solvent-air mixtures.
  • conductive useful coverings have already been used, in which an earthed copper strip construction, in particular a copper network, is arranged under the actual top cover.
  • an earthed copper strip construction in particular a copper network
  • the object of the present invention was therefore initially to find a new method or a new construction of an electrically conductive floor, which can be applied without complex removal of the old floor construction.
  • the construction of copper strips and copper wire nets to be applied with the usual means had to be abandoned and a possibility of the desirable application of a new electrically conductive useful covering to an old covering that could not be removed had to be found.
  • the laying fleece (a) provided on one side with a pressure-sensitive adhesive layer is preferably a random fleece made of polypropylene, polyethylene, polyterephthalate or polyamide fibers.
  • the entire plastic fleece should have a weight between about 40 g / m2 and about 250 g / m2, in particular from 60 to 120 g / m2.
  • a dispersion whose films have a high surface tack is particularly suitable as a PSA coating.
  • This electrically non-conductive plastic fleece or only relatively poorly conductive plastic fleece is first provided with a conductive coating which is applied in the form of a coat of paint.
  • This conductive paint contains carbon black or graphite as the active substance.
  • Primarily synthetic or natural latices are used as binders.
  • the use of polychloroprene or polybutadiene styrene or polybutadiene acrylonitrile latex has proven its worth. They expediently also contain rosin derivatives or other hydrocarbons or terpene or balsam resin in dispersed form known as "tackifiers". It is also possible to use conventional additives such as zinc oxide, chalk or barium sulfate.
  • the aforementioned also imparting conductivity Substances are expediently used as commercially available dispersions, with the usual wetting agents and emulsifiers naturally having to be present in the system.
  • the primer which can be applied by roller or by spraying, is allowed to dry for about 3 to 24 hours, preferably 5 to 12 hours, depending on the temperature and air movement.
  • the glue is then applied to this primer. Thin copper strips about 1 to 2 m long are inserted into the adhesive or even in the primer for electrical grounding. This is to ensure proper discharge of the load caused by people walking on it. It is sufficient to insert a copper tape on about 20 to 35 m2.
  • the tape itself should be about 0.05 to 0.25 mm thick. An average thickness within the above limits and a width of 5 to 15 mm is sufficient.
  • the entire floor construction is grounded by gluing thin, approximately 1 m long copper strips for 30 m2 each.
  • the electrically conductive adhesives which are used for the new process or for the construction of the new construction should contain a conductive substance such as carbon black, graphite, copper or possibly silver powder.
  • Aqueous dispersions of polyacrylic acid esters in particular copolymers of acrylic acid esters of medium chain length (C 3-8 ) and vinyl acetate, have proven to be favorable as binders for the actual adhesive. You can also use copolymers with predominant proportions of vinyl acetate and minor amounts of ethylene, propylene and / or acrylic acid esters. It is also possible to use latices made of natural or synthetic elastomers, such as polystyrene butadiene. Such basic dispersions should also be the typical ones for adhesive systems Preservatives for preservation, anti-aging agents and fillers, e.g.
  • the carbon black should be added to the adhesive as a commercially available dispersion and should be present in an amount of about 3 to 10 percent by weight, based on solids.
  • the actual floor covering should be inserted after a short period of time.
  • the covering itself has to meet high electrical conductivity requirements.
  • Carbon black or graphite-containing PVC and rubber coverings are used as electrically conductive elastomer coverings or elastic floor coverings.
  • Antistatic floor coverings are made on the basis of PVC as well as textile floor coverings.
  • Antistatic PVC coverings contain moisture-retaining chemicals, while antistatic textile coverings can be produced using steel fibers and carbon fibers.
  • the surface consisted of a velor carpet with a jute back, which was firmly glued to the screed. The carpet was carefully cleaned using a vacuum cleaner.
  • a polypropylene fleece of 75 g / m2 basis weight of a one-sided PSA coating (150 g dry / m2) was applied.
  • the pressure sensitive adhesive consisted of an acrylic acid ester copolymer (Acronal V 205, BASF) containing carboxyl groups.
  • the dispersion had a solids content of 70%, pH 4 and 1200 mPa ⁇ s at 23 ° C. (Contraves rheometer).
  • the electrically conductive paint was then applied to the fleece with a roller in an amount of 200 g (wet) over 1 m2.
  • the dispersion was composed of 42% by weight of a polychloroprene dispersion (Neoprene latex 115 DuPont), 30% by weight of natural resin dispersion (rosin derivative dispersion No. 5786 from Hercules) and 28% by weight of a 25% carbon black dispersion (Derussol AN Degussa). It also contained the usual anti-aging agents, preservatives and protective colloids.
  • the pH was 9.
  • a dried paint had a resistance of less than 3 ⁇ 105 Ohm according to DIN 53276.
  • a 1 m long copper tape measuring 1 m ⁇ 0.2 mm was placed in the still wet paint in the 30 m2 rehearsal room in order to be grounded later.
  • the adhesive had the following composition: 25% by weight aqueous 60% dispersion of a copolymer of acrylic esters with vinyl acetate (commercial product Aeronal V 303 BASF) 2 wt% monobutylene of triethylene glycol 4% by weight xylene 10% by weight rosin (dispersed) 18% by weight of chalk 9% by weight quartz flour 32% by weight carbon black dispersion (25% by weight as a commercial product Derussol AN1-25 / II from Degussa)
  • This adhesive had a resistance of less than 3 ⁇ 105 ohms after drying.
  • Electrically conductive PVC sheets of 2 mm thickness (Mipolam R 480 CE) with dimensions of 60.8 ⁇ 60.8 cm were then placed in the still moist adhesive bed. After 1 week, the conductivity of this floor construction was measured to be 1 ⁇ 106 ohms.
  • Example 1 There was a needle-fleece floor that was carefully cleaned with a vacuum cleaner.
  • the laying fleece of Example 1 which had been provided with pressure-sensitive adhesive on one side, was applied, and the soot-containing polychloroprene coating from Example 1 was then applied. After it has dried overnight, the conductive carpet adhesive is applied with the spatula (B1: tooth gap depth 2.1 mm, tooth gap width 2.3 mm and tooth bridge width 2.7 mm); the adhesive application is 400 g / m2 wet.
  • the conductive adhesive has the same composition as in Example 1.
