Our act: 30 144 I.

Applicant: Dr. Kurt Herberts & Go,

Insulation and / or cladding panel made of hard polystyrene foam,

The production of color-patterned polystyrene rigid foam by applying folds and / ο milling is
known. This material is primarily used for
the thermal insulation and insulation in the form of panels and foils has been processed in all types of rooms for years. Another surface design can be
can be achieved by subsequent pressing or shaping during foaming. This treatment achieves color and simultaneous surface effects. This type of treatment requires a smooth, evenly foamed surface.

The subject of the innovation is eiiäDämm- or. Cladding panel made of rigid polystyrene foam that passes through
one that is harder and stronger than the inner body
compacted surface, the minor largely

has uniform depressions, is characterized . - ■■■■■.

The insulation or cladding panel according to the fire can be produced in that the rigid foam With a paint-like mixture that contains solvents for polystyrene, over-sprayed or poured over is «The rigid foam is thereby dissolved on the surface in such a way that, depending on the type of solvent a different deepening and thus: one more or less uniform structuring of the surface with greater compaction at the same time entry. The surface is harder and more compact than the inner body,

A preferred embodiment is the Dämmbezw. Cladding panel according to the innovation. Characterized by a surface that contains pigments. The pigment-containing surface can be produced by adding paint-technical binders and pigments to the solvent.

The amount of solvent applied is about 50-100, preferably about 80-150 g / gm treated surface. The most volatile solvent containing mixture is expediently sprayed or poured onto the surface, wherein the usual ones used in paint technology for this purpose

The extent of dissolution of the surface and therefore the hardening and densification of the surface: the polystyrene hard foam lormkörper once, aum by the nature of the applied I / _{ösungsmittels:} other / determined by the amount of the solvent * "The less volatile the applied is solvent, ie; the longer the! solvent can act on the OTd surface before it evaporates, the longer; the dissolving process is stronger and accordingly the achieved hardening and compression of the surface. Because of the dissolving, the surface falls back a little and hardens. The larger the amount of solvent used, the stronger the dissolving process and the effects described above. V;

The mixture with which the polystyrene rigid foam - Lormkörper starting products are treated, can be made exclusively from one or more Iiösungs means pass * Particularly good results will be obtained if the mixture still has binders to it contains additional hardening of the surface. the Amount of binders and / or color pigments the extent of the desired hardening, sealing and / or discoloration * The binders can contain plasticizers in the usual way. ; -

Bs is therefore "preferred that the surface of the Dämmbezw. Cladding panel additionally contains paint binding agents according to the price increase.

lie insulation or Cladding panel according to the innovation "possesses an extraordinarily even opposite the inner body harder and more compacted surface , which is also characterized by a pleasing and aesthetically pleasing appearance. the Use of polystyrene, especially in IPorm of Sheets and foils for cladding objects of all kinds will open up further possibilities. I am a particular advantage of the insulation or cladding panel according to the furnace is that as a starting product for their production itself such Polystyrene hard foam panels can be used, which are slightly scratched and uneven Show surface. Even from such products that are practically unsaleable per se, Dämmbezw. Cladding panels are made according to the inflation that a uniform and the ge Requirements have a satisfactory surface. To produce the insulation or Cladding panel According to the innovation, products can be used that would otherwise be referred to as waste would be.

The production of the insulation or cladding panel according to the innovation is extremely simple and "No" special technical equipment is required.

All polystyrene solvents can be used as solvents Substances are used, with "preferred are those which are as harmless as possible for physiological reasons and have a low risk of explosion or fire cause. Examples are acetone, dibutene ^ .- phthalate, {Dolojul, methylene chloride, ethyl acetate, Ethyl glycol acetate and mixtures thereof.

Polyvinyl acetate, for example, is particularly suitable as a binder. All common pigments can be used as pigments can be used, whereby the color is arbitrary »

is applied in an amount of about 100 g / sqm on a polystyrene hard foam board sprayed on and in the air
