Description

The invention relates to an insulating board, in particular of expanded polystyrene (EPS) or extruded polystyrene (XPS), according to the preamble features of claim l.

Insulating boards made of expanded or extruded polystyrene for the insulation of building parts u.a. are known. They are e.g. produced by expansion or extrusion of styrene polymer particles and subsequent cutting.

Mainly insulation boards are made from pigment-free styrene polymer particles.

In order to achieve the goal of improving the insulating effect of usually white, i. In order to improve, to achieve, non-colored plates, plates are produced which additionally contain particles with dark pigments, e.g. Soot, graphite and the like a ..

Pure dark / gray / black plates have the disadvantage that they heat up excessively when exposed to heat, for example, tanning, thereby liquefying the adhesive used to fix the plates to, for example, a building wall. This can cause the insulation to be completely or partially detached or displaced.

EP 1 815 077 proposes insulation boards consisting of two parts, a part with predominant insulating effect consisting of a gray expanded polystyrene and containing athermane substances for an additional function and a second part of hard foam with at least one further protective property. The athermanous substances may in turn be soot, graphite, etc., and act as infrared absorbers or reflectors. The other plate part fulfills protective function. Both parts are thermally welded together, with heated metal needles piercing the superposed parts. As a result, connecting contact surfaces are formed in the vicinity of the needles. The number of contact surfaces corresponds to the number of needles and there is no continuous connection surface of the parts. It is also known to arrange a dark reflector plate between two white cover plates.

From the CH 702 596 A1 For example, an expanded polystyrene (EPS) insulation board is known which comprises an insulating layer and a cover layer with an additional protective function. The cover layer reflects incident sunlight and protects the insulation against excessive heating.

A disadvantage of this plate, however, proves that this completely formed from pigment-free particles cover layer has a pure white color and thus almost completely reflects the incident sunlight. In particular, this leads to the processing of the plates and the processing of the insulated area to impair the processor, which often suffer from eye injuries or retinal damage.

Another disadvantage of the plates proves that they almost completely reflect the radiated heat radiation. This is undesirable under Dämmgesichtspunkte, since not the full insulation potential of the plates is used.

The object of the present invention is therefore to provide an insulation board which, on the one hand, improves the insulating effect of known panels and, on the other hand, minimizes the health risks of the processors in the use.

The object is achieved by an insulating panel made of expanded polystyrene (EPS) or extruded polystyrene (XPS), which comprises a insulating layer (insulating layer) and a cover layer with an additional protective function, wherein the insulating layer and the cover layer connected to form at least one contact surface are. The insulating layer comprises or consists of expanded particles comprising or including dark pigments or pigment compositions, while the top layer contains unpigmented expanded particles and / or expanded particles comprising colored, especially light colored pigments or pigment compositions. While the latter feature reduces the high reflectivity of the adjusted sunlight, the invention further contemplates that an admixture of expanded particles having dark pigments or pigment compositions is provided in the cover layer. Through this admixture, the insulating performance of the insulation board is improved without affecting the protective function of the cover layer for the underlying insulating layer. Also, the dark pigments or pigment composition having particles lead to a slight shading of the cover layer and lower the reflection so far that sufficient protection is ensured without leading to adverse health effects when using the plates. At the same time, however, the overall insulation performance of the insulating board is improved and further increased by the coloring of the particles and the injected dark particles, without significantly worsening or even abolishing the protective function for the dark insulating layer.

It is considered advantageous in this context if the insulation board in the top layer an admixture of between 0.05 and 35%, in particular 0.5 to 20%, preferably 0.7 to 10% based on the total particle number, colored or dark pigments or colored or dark pigment compositions having, expanded particles is provided.

Preferably, the particles of the cover layer between 0.05 and 10%, in particular 0.5 to 5%, preferably 0.7 to 3% of at least one light and / or colored, in particular and without limitation white, yellow, blue, green or orange pigment or a bright, light and / or colored, in particular and without limitation thereto, white, yellow, blue, green or orange pigment composition based on the particle mass. The cover layer is thereby given a continuous coloration. In addition, the colored or dark pigments or pigment composition having expanded particles are mixed into the cover layer as Sprengsel and are there recognizable as individual particles or particle islands. Of course, there is also the possibility that the admixed particles are used for labeling. Thus, for example, different colors for different uses, manufacturers o. The like. Of the insulating boards act distinctive. Green Partikeleinsprengsel or a contrast d green or greenish color of the outer layer can be used, for example, as an indication of the recyclability of the plates.

Depending on the manufacturing process, the pigments or pigment compositions are added to the particles before, during or after expansion. This results, on the one hand, in differences in color, on the other hand in the penetration of the particles with the pigments or pigment compositions.

In a preferred embodiment, an admixture of dark pigments having expanded particles is provided in the cover layer. In this case, for example, the base color of the cover layer may be white, or these may be formed from completely pigment-free particles. As a result, however, the cover layer is no longer completely composed of pigment-free particles or of completely pigment-free particles.

The starting plates are prepared in conventional methods from corresponding particles or particle mixtures which are expanded or extruded before or during plate making. Also blocks can be made from which the layers are then cut. The use of the word constituent "layer" in the terms "cover layer" and "insulating layer" is to be understood in the context of the present invention always in the sense of a flat, plate-shaped structure with a certain dimension and inherent stability.

The aim is to provide an insulation board with above-average, but at least measurably improved insulation performance available.

The insulation boards according to the invention therefore preferably has an insulation layer which has a thickness which corresponds to a multiple of the thickness of the cover layer, while the insulation board has a defined thickness.

As low is considered in this context, if the thickness of the cover layer is between 1 and 4%, in particular 2% of the thickness of the insulating layer. Percentages of up to 10% are also conceivable. In other words, the cover layer favorably has a thickness of between 1.5 and 15 mm, preferably between 3 and 10 mm. The final thickness of the cover layer is preferably set by appropriate milling of the cover layer to the desired nominal size.

The insulation board according to the invention is characterized in a preferred embodiment in that athermane substances, carbon black, graphite, metal powder, metal oxides or combinations thereof are provided as dark pigments. As a result, the insulation performance of the plate is set. The preferred materials used are selected depending on the particular application.

It is considered favorable if the insulating layer and the cover layer in the contact surface are connected over the entire surface or at points, the connection in particular by thermal or chemical welding or bonding of facing surfaces of cover layer and insulating layer or by co-expansion or co-extrusion of the particles formed by cover layer and insulating layer. Regardless of the manufacturing process, an insulation panel comprising at least two layers is thus provided, the invention not being limited thereto but also comprising panels having more than two layers.

The insulation board is further distinguished by the fact that the pigments are incorporated in the expanded particles or incorporated on or in the cladding layer. In any case, the cover layer consists of not completely pigment-free particles. The incorporation or addition of pigments on or on or in the particles causes a coloring of the cover layer. This coloring can also come about through the fact that in the spaces between the expanded particles and on The expanded particles themselves pigments are deposited. In any case, the insulation boards fulfills the object of the invention.

It is considered advantageous if the proportion of pigmented expanded particles based on the entire insulating layer is between 1-100%, in particular between 25 and 95, preferably between 50 and 90%.

An embodiment of the invention which is regarded as favorable provides that the insulation board has structuring, in particular grooving, in at least one outer surface. This structuring, in particular grooving, is embodied as preferably uniform grid or substantially pyramidal or similar structures. The structures are preferably arranged in the surface of the insulating board which, when installed i. Use of a surface, in particular facing the building or house wall. By structuring on the one hand irregularities in the surface to be insulated can be compensated, on the other hand, these cause an improved application of adhesive and thus favor the adhesion between insulation boards and to be insulated surface. By providing a chamfer as completion of structuring and at the edge of the surface provided with the grooving results in a so-called adhesive or mortar bag. That is, excess mortar, which is present in the installation of the finished insulation board, can penetrate into the space formed by the chamfers of plates (pocket) side by side, as soon as the insulation boards are pressed against the surface to be insulated. It is effectively prevents the formation of joints between plates, which occurs when no such mortar or adhesive bags are provided. The arrangement of the bevels takes place when the plates are milled. Alternatively, it is also possible for the structures to be introduced into the baseplate or insulating layer during production and only for milling of the cover layer.

The insulation board according to the invention has at its periphery lateral boundary surfaces, in or at which preferably at least one groove and / or a spring is provided. The design with a tongue and groove structure a significant improvement in the arrangement of the insulation boards is achieved. As a result, a more even surface is provided, which then serves for the plaster application.

A particularly favorable embodiment is considered when a groove and / or a spring in the lateral boundary surface in a defined, consistent and independent of the plate thickness distance from the plate surface is arranged. This ensures that even with different thicknesses of the insulating layer formed a uniform plate surface can always be provided. The arrangement of groove and / or spring with a defined distance to the plate surface allows the combination of insulation boards of different thickness and at the same time ensures the uniform surface of the insulating surface.

Under Dämmgesichtspunkte proves to be advantageous if the structures are formed in the side surfaces of the insulation boards in the manner of a Stufenfalzes. As a result, thermal bridges, which form at the joints of the insulation boards in the finished insulation layer, effectively prevented.

Described below is a method for producing the insulation boards according to the invention.

• (i) Zusammenführen einer Deckschicht und einer Dämmschicht, wobei Deckschicht und Dämmschicht zusammen eine größere Dicke als das Nennmaß der herzustellenden Dämmplatte aufweisen,
• (ii) Verbinden der sich gegenüberliegenden Flächen von Deckschicht und Dämmschicht,
• (iii) Abfräsen der Oberflächen der gebildeten Dämmplatte, und
• (iv) Einstellen eines definierten Nennmaßes der Dämmplatte.

The method of manufacturing an insulating board provides that the board is manufactured in a process involving several steps. The method comprises the following steps:

• (i) combining a cover layer and an insulating layer, the cover layer and the insulating layer together having a greater thickness than the nominal size of the insulating board to be produced,
• (ii) bonding the facing surfaces of the cover layer and the insulating layer,
• (iii) milling the surfaces of the formed insulating board, and
• (iv) setting a defined nominal size of the insulation board.

The preparation of the finished insulation boards conditioned to adjust uniform nominal dimensions over the entire plate production, a post-processing of the formed insulation boards. This is ensured by the milling of the surfaces of the raw but already connected insulation boards. Overall, therefore, regardless of the circumstances, results and conditions when welding or bonding the layer surfaces, provided insulation boards that have uniform nominal dimensions. The final dimensional adjustment of the plates is thus independent of the joining of the layers and ensures uniform plate dimensions over the entire production or production batch.

• (v) Bearbeitung der Seitenkanten der Dämmplatte zum Einstellen eines Nennmaßes hinsichtlich Plattenbreite und Plattenlänge, wobei Schritt (v) vor, nach oder gleichzeitig mit Schritt (iv) durchgeführt wird.

A development of the method provides that a further processing step is provided. This is step:

• (v) machining the side edges of the insulation board to set a nominal size in terms of plate width and plate length, wherein step (v) is performed before, after or simultaneously with step (iv).

This also significantly improves the quality of the plates formed and further unifies their dimensions. This offers particular advantages when large areas are to be covered with insulation boards. Even the smallest irregularities in the slab size lead to unevenness, which can be seen in the applied plaster. Thus, the additional step of machining the side edges, as before, the step of milling the surfaces, in particular the face for setting the nominal size, is crucial for improving the product quality.

In order to produce the insulation boards, it is preferable in step (ii) to provide simultaneous heating of the opposite surfaces of the cover layer and the insulating layer. Subsequently, these surfaces are pressed to form a contact surface against each other and thus the surfaces connected over the entire surface. The pressing can be done via plunger or rollers.

In addition to the full-surface merging of the cover layer with the insulating layer in the process of course also has the opportunity to perform only selective heating of the opposing surfaces of cover layer and insulation layer and subsequently press these surfaces against each other to form a contact surface, thus selectively connect the surfaces. The selective heating can be done as already stated by needling. Of course, appropriately trained welding mirrors are used, which are configured so that a point heating takes place. Advantage of this is the reduction of energy consumption compared to a full-scale heating.

Preferably, the connection of the plates takes place under pressure and / or by oscillation, wherein the surfaces are heated to above the softening temperature of the polystyrene and then connected.

Optionally or alternatively, it is provided in the method that in step (ii) a chemical softening of the opposing surfaces of cover layer and insulating layer by application of suitable solvents is provided. Subsequently, these surfaces are pressed to form a contact surface against each other and thus connected the surfaces.

Optionally or alternatively, it is provided in the method that in step (ii) a full-surface or partial adhesive application is provided on at least one of the opposing surfaces of cover layer and insulating layer and subsequently pressed these surfaces against each other forming a contact surface and the surfaces are thus glued.

• (vi) Einbringen, insbesondere Einschneiden oder Einfräsen von wenigstens einer Nut und/oder einer Feder in eine seitliche Begrenzungsfläche am Umfang der Dämmplatte.

A preferred embodiment of the method provides that it further comprises the step:

• (VI) introducing, in particular cutting or milling at least one groove and / or a spring in a lateral boundary surface on the circumference of the insulation board.

The implementation of this step can be provided before or after the step of setting a defined nominal size of the insulation board and / or the processing of the side edges of the insulation board for setting a nominal size in terms of plate width and plate length.

• (vii) Einbringen, insbesondere Einschneiden oder Einfräsen einer Struktur, insbesondere einer bevorzugt rasterartigen Rillung oder von im wesentlichen pyramidenförmigen Strukturen in wenigstens eine außenliegende Oberfläche der Dämmplatte.

A preferred embodiment of the method provides that a further method step is provided. These are:

• (vii) introducing, in particular cutting or milling a structure, in particular a preferably grid-like groove or of substantially pyramidal structures in at least one outer surface of the insulating board.

• (viii) Einbringen, insbesondere Einschneiden oder Einfräsen eines Stufenfalzes in eine seitliche Begrenzungsfläche am Umfang der Dämmplatte

vorgesehen werden. Die Schritte zur Oberflächen- und Seitenflächenbearbeitung können zeitgleich oder zeitversetzt durchgeführt werden, je nach Anordnung, Bedienung, Verfügbarkeit oder Einsatzmöglichkeit der entsprechenden Fräsaggregate und Anforderungen an die Platten.Alternatively or as a further development of the method, the step

• (viii) introducing, in particular cutting or milling a Stufenfalzes in a lateral boundary surface at the periphery of the insulating board

be provided. The steps for surface and side surface processing can be carried out simultaneously or with a time delay, depending on the arrangement, operation, availability or possible use of the corresponding milling units and requirements for the plates.

When using an insulating board as described above, these are used to insulate a surface, in particular the wall surface of a building. The plate can realize all advantages of the invention here and ensure the formation of a uniform surface with improved insulation effect.

In use, the insulating layer is preferably the surface, in particular facing the building wall and the cover layer facing away from the surface, in particular the building wall.

The invention also comprises an insulating layer formed from a plurality of insulating panels on a surface, for example a building wall.

The invention will be explained below with reference to exemplary embodiments.

3 a schematic representation of an embodiment of the manufacturing process.

1 shows in a not to scale representation of insulation board 1 made of expanded polystyrene (EPS). This has insulating or insulating layer 2 and a cover layer 4 with an additional protection function. The insulating layer 2 and the topcoat 4 are at training at least one contact surface 3 connected with each other. The insulating layer 2 comprises or consists of expanded particles which contain or contain dark pigments or pigment compositions. The cover layer 4 has expanded particles which have colored, especially light pigments or pigment compositions in order to reduce a strong reflection of the incident sunlight. Furthermore, located in the topcoat 4 an admixture of expanded particles having dark pigments or pigment compositions. By this admixture, the insulation performance of the insulation board 1 improved without the protective function of the topcoat 4 for the underlying insulating layer. The dark pigments or pigment composition having particles in the cover layer lead to a shading of the cover layer 4 and lower the reflectance to a level sufficient to provide protection without compromising health when using the panels. The cover layer is produced in conventional processes, ie particles are extruded or expanded and used to form blocks or plates, which are then further processed, for example cut. The differently colored particles are mixed or mixed in the formation of the plates / blocks.

2a to 2c show possible embodiments of the insulation board according to the invention 1 , In the 2a shown insulation board 1 has in its side surfaces under Dämmgesichtspunkten favorable Stufenfalze 5a . 5b on, when laying the insulation boards 1 pushed against each other or pushed over each other. These structures in the side surfaces of the insulation boards 1 like a Stufenfalzes avoid the formation of thermal bridges, which would otherwise form at the joints of the insulation boards in the finished insulation layer.

2 B shows a further embodiment of the insulation board 1 which has a structuring, in particular a groove, in at least one outer surface. This structuring is as a uniform grid with substantially pyramidal structures 7 educated. The structures 7 are in the area when installing the insulation boards 1 facing a building or house wall is arranged. Through the structures 7 can be compensated for an irregularities in the surface to be insulated. In addition, the adhesive application and thus the adhesion between insulation boards 1 and improved to be insulated surface. The insulation board 1 has a chamfer 11 as completion of the structuring and on the edge of the grooved surface. This results in a so-called adhesive or mortar bag when installing the finished insulation boards. In through the chamfers 11 Adjacently built-in panels of limited space (pocket), excess mortar can penetrate as soon as the panels are pressed against the surface to be insulated. It is effectively prevents the formation of joints between insulation boards, which occurs when no such chamfers 11 and from this forming mortar or adhesive bags are provided. The arrangement of the chamfers takes place in the embodiment of 2 B in the course of the milling of the plates.

2c shows a further embodiment with groove 6b and spring 6a in the lateral boundary surface. groove 6a and spring 6b are arranged in a defined constant, independent of the plate thickness distance from the disk surface. This ensures that even with different thicknesses of the insulating layer formed a uniform plate surface can always be provided. The arrangement of groove 6a and or spring 6b with a defined distance to the plate surface allows the combination of insulation boards 1 different thickness and at the same time ensures the uniform surface of the insulating surface.

3 shows an embodiment of the method for producing an insulating board 1 strongly schematized. In the process, first a cover layer 4 the insulation board to be manufactured 1 , with the insulating layer 2 the insulation board to be manufactured 1 merged. The layers initially have a greater thickness than the nominal size of the insulating board to be produced 1 , Thereafter, the opposing surfaces of cover layer 4 and insulating layer 2 connected. In the embodiment of 3 is a simultaneous and full-surface heating of the opposite surfaces of cover layer 4 and insulating layer 2 by means of a heating mirror 8th carried out. The heated and superficially liquefied surfaces are pressed against each other to form a contact surface and the surfaces thus connected over the entire surface. The pressing is done by pressure rollers 9a . 9b performed on which the raw insulation board 1 in the direction of arrow A is passed.

A cover layer 4 will be roughly parallel to the insulation layer 2 fed and subsequently the opposing surfaces are simultaneously heated to the extent that a firm connection between the two layers is achieved by pressing these surfaces. The heating is carried out in the embodiment by means of mirror welding and thereby a molten film is formed on the heated surfaces. The connection is adhesive-free and full surface. The heating temperature is about 300 ° C in the embodiment, whereby the formation of a sufficiently molten film is ensured. Covering layer and insulating layer have as output plates an excess, which is reduced as a result of melting and bonding. The manufactured insulation board 1 does not yet have the required nominal size. This is adjusted by the subsequent milling of the surfaces. The insulation board 1 consists of two layers, ie a dark and insulating layer of insulation 2 and a partially reflective cover layer 4 , which are connected to each other over their entire surface.

The insulating layer 2 contains particles containing dark pigments. The insulating layer 2 is placed facing when using the wall or surface to be insulated.

The cover layer 4 It consists of colored, brightly pigmented particles and is turned outwards, with the top layer 4 significantly thinner than the insulating layer 2 , In addition, the topcoat contains 2 a proportion of particles uniformly distributed throughout the layer. These are much darker than the surrounding particles.

In the production of the plates become bright cover layer 4 and dark insulation layer 2 fed in parallel to the heating and pressing elements, so that as a result the insulation board 1 initially as a raw insulation board with only rough dimensions arises. The to the heating mirror 8th guided layers melt due to heating and a molten film is formed. This also causes a reduction in the plate thickness. Under formation of the contact surface 3 becomes the topcoat 4 through the pressure rollers 9a . 9b against the insulation layer 2 pressed, resulting as a result of the melting and subsequent pressing of the layers, the raw insulation board with not yet set nominal size.

After connection of the topcoat 4 with the insulating layer 2 The nominal dimension of the raw insulation boards is adjusted by marginal milling and milling of the surfaces. At the same time, structures such as tongue and groove or stepped rebates can be milled into the side surfaces.

To that required nominal size of the finished insulation board 1 set, there is a top and bottom side Befräsung the raw insulation board by the downstream milling drums 10a . 10b , Of course, in this or a subsequent process step, an all-round, preferably six-sided processing of the insulation board 1 be carried out to uniformly and reproducibly dimensioned insulation boards 1 to obtain.

The production of finished insulation boards 1 conditioned to adjust uniform nominal dimensions over the entire plate production, a post-processing of the formed insulating boards 1 , This is done by milling the surfaces of the insulation boards 1 ensured. The result is thus insulating boards 1 provided that have uniform nominal dimensions.
