Definitions

  • the invention relates to a fire-retardant primer for surfaces of components, cladding, documents or the like, in particular for the interior construction of rooms, vehicles or the like.
  • the adhesive adheres to many smooth surfaces of the components only to a limited extent, so that there is a risk that the decorative layer or film will peel off prematurely. It is the task to remedy this and to provide a fire-retardant primer for surfaces of the parts mentioned.
  • this primer provides effective protection for the component behind it, at least for a limited time. Above all, it prevents the flames from directly impacting the decorative layer or film on the component behind. The primer prevents inflammation from occurring on the surface of the component due to the supply of energy.
  • Both water-soluble potassium and sodium silicates can be used as water glass, although the potassium silicates are preferred.
  • the fireclay cement is mixed with the water glass in such a way that it can be easily spread or applied to the surface with conventional spray guns without dripping or running off. The applied layer dries relatively quickly.
  • small amounts of water e.g. about 5 vol .-% of the total mass added.
  • kaolin primer While a primer with fireclay cement takes on a glassy, hard surface structure after drying, which no longer allows moisture absorption, the primer formed with kaolin is only vitreous when completely dry. However, it can absorb moisture from the surrounding atmosphere. It can therefore be diluted with water to any desired consistency and is therefore particularly suitable for application with a spray gun.
  • the kaolin primer is also particularly thin to apply and is inherently lighter than fireclay cement.
  • the K ⁇ olinsig mich ist is versatile, sticks to practically any surface and is particularly easy to process.
  • the kaolin priming also shows an extraordinarily high thermal conductivity.
  • the ratio of kaolin to water glass should be around 1: 2. This mixture results in a spreadable mass. Water can be added to the mixture to increase the flowability, up to a ratio of kaolin to water of 1: 1.
  • Too much water glass affects the fire-retardant properties. Too little water glass affects the workability.
  • the kaolin primer is to remain dry and hard, it must be covered airtight, e.g. through an acrylic paint application.
  • the primer adheres to the often smooth surface of the components, which are usually made of plastic, e.g. a phenolic resin or epoxy resin is formed, but can also consist of wood, cardboard or the like.
  • plastic e.g. a phenolic resin or epoxy resin
  • an adhesion-promoting layer before the fired refractory cement is applied.
  • an adhesive layer made of acrylic emulsion paint has proven itself.
  • the surface of the primer can also be the visible surface.
  • a common design can also be applied to the outer surface of the primer.
  • cork layer or decorative film can be applied with the aid of a hot melt or adhesive.
  • a further layer of vermiculite powder made up with water glass as a binder is expediently provided between the adhesion-promoting layer and the primer.
  • the fire-retardant effect of the primer can be substantially improved by admixing a sufficient amount of gum particles or mica powder with the acrylic dispersion used to impart adhesion and / or to cover the primer. This leads to e.g. in the event of exposure to flame, the adhesive layer quickly lifts off the base and thus forms additional fire protection.
  • the proportion of mica powder can be about 20% by volume.
  • the acrylic dispersion layer used for covering can additionally serve as a carrier layer for a hot melt adhesive for applying a decorative layer or film.
  • the hot melt adhesive is expediently designed to be fire-resistant by admixing appropriate additives.
  • a contact adhesive can also be used.
  • a layer system based on the new primer is obtained which compensates the fire-endangering properties of the components used for interior construction to a relatively high degree.
  • the known refractory materials such as high-clay content, clay-rich, acidic or basic products and silica products, can be used for the primer.
  • chamotte products and kaolins are particularly preferred.
  • the powdery substances used such as vermiculite, mica, kaolin and fireclay cement, are expediently used in such a fine form and mixed up that the mass can easily spread or can be applied in thin, even layers with conventional spray guns.
  • the layer system does not change when exposed to temperatures below 500-600 ° C. At higher flame temperatures, the intermediate layer of vermiculite powder mixed with water glass releases water vapor which, depending on the speed of the temperature increase, lifts the layer system in small or large bubbles from the base to a small or large extent. If the flame treatment temperature is high enough, the firebrick cement layer melts or sinters together with softening and solidifies to a hard, largely impermeable glass-ceramic layer that withstands the flame treatment unchanged. Vapors or combustion phenomena do not occur. The kaolin layer dries out first and becomes hard. Otherwise it behaves similarly to the fireclay primer.
  • the primer for example 20 - 50 ⁇ m thick, reliably protects a base made of wood or cardboard in the case of direct flame treatment at temperatures of 850 ° C. and more over a period of 2 minutes and more.
  • the protective effect can be increased by removing the layer system
  • the kaolin is chemically inert, easily dispersible, weather-resistant and physiologically harmless.
  • the main components are Si-0 2 (approx. 45.5%) and AL-O- (approx. 38.5%).
  • the average grain size is well below 2 ⁇ .
  • this kaolin is particularly suitable for processing with conventional spray guns if the consistency is set accordingly, since the spray nozzles neither clog nor wear appreciably.
