Definitions
- the invention relates to an insulation element for application to building facades Thermal insulation composite systems, consisting of a mineral fiber molded body, the two large, parallel and spaced surfaces has, which are connected to each other via narrow sides, the mineral fiber molded body one preferably at right angles to the large surfaces has aligned fiber path and on at least one large surface has a coating that the adhesive bond between the mineral fiber molded body and a construction adhesive, in particular an adhesive mortar and / or one on the Mineral fiber molded body applied plaster enlarged.
- Thermal insulation composite systems consist of insulation elements, which as a rule be applied to the outer walls of heated buildings.
- the attachment the insulation elements can be by means of adhesives and / or mechanical fasteners respectively.
- the insulation elements with mostly two applied one after the other Plaster layers, namely a basic plaster and a top plaster layer covered.
- the base plaster layer applied directly to the insulation elements is in the Usually with a tensile fabric, for example made of glass fibers, carbon fibers or reinforced with wire mesh. This reinforcement prevents one Cracking of the plaster layers as a result of the hardening of hydraulic binders and the drying out of the shrinkage occurring shrinkage.
- Insulating elements made of expanded polystyrene hard foam or mineral wool. To a very small extent, lightweight aerated concrete slabs are also used used.
- the present invention is based on insulating elements made of mineral wool.
- Such mineral wool insulation elements are basically divided into two types.
- Usual mineral wool insulation elements are manufactured with bulk densities between approx. 120 to 170 kg / m 3 .
- Such insulation elements have a course of the mineral fibers, which is oriented at least in the near-surface zones flat or parallel to the large surfaces. This structure in particular results in a low transverse tensile strength, but also leads to a comparatively low thermal conductivity in the range of approx. 0.040 W / mK and to a relatively high compressibility.
- a variation of these insulation elements provides that an outer surface layer is compressed to approx. 130 to 170 kg / m 3 , while the further area of the insulation element has only a density of approx.
- the thermal conductivity can drop to approximately 0.035 W / mK.
- the highly compressed surface layer improves the compressive strength of the insulation element, while the transverse tensile strength does not increase significantly.
- insulation material elements for thermal insulation composite systems the individual mineral fibers mostly run at right angles the large surfaces, from which significantly higher transverse tensile strengths, but also result in a higher thermal conductivity.
- Such insulation elements generally referred to as lamellar plates. Because the thermal resistance a composite thermal insulation system, etc. on the thickness of the insulation elements depends, the bulk density of such lamella plates is reduced to the extent that the insulation element belongs to the thermal conductivity group 040 according to DIN 4108 falls, but still has transverse tensile strengths of greater than 80 kPa.
- the manufacture of lamella plates described above is known per se.
- the insulation elements can be parallel to the large ones Mineral fibers stored on the surface perpendicular to the main orientation of these individual fibers separated by slices and the sections rotated by 90 ° and again be put together.
- Main orientation of the mineral fibers as the primary material for the production of Insulation elements serving lamellar panels transverse to the production direction align. In order to obtain a high tensile strength of the slat plates, it is sufficient but it does not make the mineral fibers more or less loose towards each other layers. Rather, an intensive folding of the mineral fibers is necessary for this.
- the mineral fibers impregnated with binders continuously intensely folded by longitudinal and vertical compression.
- This Folding takes place particularly rationally in the longitudinal direction of the production, so that the fibers when pushed together predominantly across the force component align.
- the unfolded structure is made by curing a binder, fixed in a continuous furnace, for example.
- thermosetting synthetic resins between approx. 3% by mass and approx. 8% by mass becomes firm, but only in Elastic structure is obtained in narrow areas.
- Such insulation elements differ significantly from flexible and easily compressible Insulation mats or insulation felt.
- the maximum height of a hardening furnace is procedural and economical About 200 mm. This height also determines the material thickness of the insulation elements with right angles to the large surfaces Graining. The width of such insulation elements is in the range of 1.2 m.
- the insulation elements are mostly under Use of adhesive mortars over the whole or in part on building facades glued.
- the adhesive mortar also for the production of the reinforced base coat used.
- the top layer of plaster is only still between approx. 0.5 and 1.5 mm.
- plaster layer thicknesses of a total of at least 3 to 7 mm or up to about 15 mm preferred because they have more beneficial long-term usage properties.
- the inherent loads of the Thermal insulation composite system increased, which ultimately through the connection of the Thermal insulation composite system to be included with the building facade.
- the adhesive connection and the plaster layers must have moisture resistance or largely resistant to the effects of rainwater his. Furthermore, the materials used must comply with the relevant DIN 4102 standard must not be flammable. For the reasons mentioned for the adhesive mortar and plaster mixes hydraulic binders such as cements according to DIN 1164, hydraulic and highly hydraulic limes alone or in Mixtures with each other and with other latent hydraulic substances used. To ensure that the dominant thin plaster layers are as light as possible To reach the base coat, white cements are often used together mixed with granular aggregates made of marble and / or crystalline calcites.
- the adhesive mortar becomes bulge-like when processing the insulation elements all around the circumference of the insulation element and also in shape two central spots (chunks) applied. After the insulation element is fixed on the building facade with the adhesive mortar, the insulation element then secured and fastened by so-called insulation holders.
- Insulation holders of this type can be used both before and after the plaster layer has been applied be introduced so that they can be added later
- the reinforcement mesh in the base plaster layer also holds the insulation capture and thus a better bond of the insulation element with the building facade produce. This can, thanks to the better introduction of force specific number of insulation holders per unit area significantly reduced become.
- the adhesive mortar is used first preferably systematically into a thin layer into the hydrophobic Surface incorporated before to level with a toothed trowel in the lighter bumps required strength is raised.
- Layer thicknesses are 10 mm thick.
- the adhesive mortar can also be used in regular strips are applied to the building facade.
- the insulating material elements are then laid with a staggered joint around the adhesive bed to prevent the edges of the insulation elements from sticking together are later pulled off the building facade by the contracting plaster become, which can lead to the formation of cracks.
- the commonly used adhesive mortars contain parts of thermoplastic Plastic dispersions, which among other things the adhesiveness, the shrinkage behavior and improve the elasticity of a cement / lime-bound mortar. These mortars are used internationally with polymer-cement-concrete (abbr .: PCC) designated. On the by the organic binders and by additions of Oils hydrophobized, therefore not capillary absorbent surfaces of the insulation elements even adhesive mortars only adhere to a limited extent. To the bond between to improve the insulation element and the adhesive mortar, it is known Before applying the adhesive mortar, an adhesion-promoting layer, for example from a dispersion silicate paint to the one to be coated with adhesive mortar Apply the surface of the insulation element.
- an adhesion-promoting layer for example from a dispersion silicate paint to the one to be coated with adhesive mortar Apply the surface of the insulation element.
- Such dispersion silicate paints can easily on the basis of their consistency large surfaces of the insulation elements are sprayed on and contain not inconsiderable amounts of fillers with grain sizes smaller than approx. 50 ⁇ m.
- suitable fillers are kaolin, chalk, marble powder, talc, Quartz flour, cristobalite and the like.
- quartz flour, talc quartz flour
- cristobalite may have been released in recent years Health-endangering dusts during processing or processing and as a result natural weathering has been systematically avoided.
- adhesion promoters Layers lie in the form of thin layers on the surfaces of the fibers or on the lamella plates on the fiber tips.
- DE 41 10 454 A1 describes an adhesion-promoting coating known, on the large surface facing the base layer of basalt fiber boards is arranged.
- the hydrophilizing, air-permeable coating only wets the surface zone of this insulation element up to a depth of 2 mm. Excess hydrophilizing coating is suctioned off, the dust present on the surface is also removed.
- This publication is an alkali water glass solution as a hydrophillizing coating known to be added to increase the rigidity of calcium carbonate can.
- a significantly improved form of impregnation of the large surface area Insulating element is known from EP 0 728 124 A1.
- This publication discloses impregnation of a thin zone near the surface with the aid of a foamed coating composition, which consists of a mixture of 25 to 40 % By mass of silica sol (40%), 2 to 20% by mass of plastic dispersion, 0.3 to 1.5 Mass% foaming agent and 0.05 to 0.5 mass% foam stabilizer as well as an inorganic flame retardant as required.
- This coating mass is in the form of a foam on the surface to be impregnated distributed and with the help of a squeegee into the open, but very fine-pored surface of the insulation element pressed in.
- the stability of the foam bubbles enables a certain pressure transfer to the silica sol even if the foam bubbles in direct contact with a mineral fiber have burst.
- the Components of the coating evenly in low concentrations be distributed over the surface of the insulation element. Usual order quantities are about 20 to 100 g dry matter per square meter. This surface impregnation however, does not lead to a noticeable increase in strength the surface, especially not against pressure loads.
- U1 is an insulating element made of mineral fibers known that a continuously adhesive-free, continuously produced slat structure having.
- This insulation element has a coating on the surface selected as visible side. It is considered essential here that the shafts of the individual fibers are only a small depth from the coating be included.
- the coating should have at least the same transverse tensile strength have, like that of the insulation element and in the range of 40 up to 100 kPa.
- AT-PS 378 805 is also an insulation element with a coating known in which the individual fibers predominantly at right angles to Surface of the insulation element are oriented.
- the one from a mortar or The existing coating has a material thickness of 8 to 20 mm. Cement and / or hydraulic are used as binders for the mortar or concrete Limes known.
- the mortar also contains plastics. The making of this Insulation element takes place in that the not set mortar in a Mold filled and the insulation element is then pressed to to achieve an adequate connection of both layers.
- the coating can be reinforced with a fabric made of preferably alkali-resistant glass fibers his.
- EP 0 719 365 A1 is an insulation element in the form of a lamella plate known, the cut surfaces with a thin set Layer of adhesive mortar is provided.
- the object of the invention is to further develop an insulation element in such a way that it has an improved affinity for the building materials to be installed with the insulation element and at the same time has constant material properties which, in particular, provide high transverse tensile strengths and compressive strengths even when handled improperly.
- the solution to this problem in a generic insulation element for the thermal insulation composite systems to be applied to building facades provides that the coating consists of an impregnation and a pressure-resistant layer with great affinity for hydraulically setting construction adhesives, such as adhesive mortars, cement mortars or other mortars.
- Such a coating ensures good affinity due to the impregnation the insulation element for adhesive mortar or the like. Beyond that a pressure-resistant layer is provided, which is also an excellent affinity to the hydraulically setting construction adhesives and beyond disintegration or destruction of the fiber bond due to improper force application avoids in the large surface of the insulation element, so that The transverse tensile strength and compressive rigidity of the insulation element are retained.
- the impregnation is preferably in the zones near the surface, in particular arranged at a depth of 1 to 5 mm of the mineral fiber molded body.
- the Layer thickness refers to a virtual smooth surface, so because of the Unevenness in the surface to be coated does not necessarily mean the layer thickness is evenly formed.
- the impregnation from non-flammable substances especially from a water glass solution with small proportions of plastic dispersion, silicate paint, dispersion silicate paint, Silica sol and / or nanoparticle dispersed silica.
- the usage such substances for the impregnation leads to the insulation element overall classified as non-combustible within the meaning of the relevant standards can be.
- the nanoparticle dispersed silica can preferably after harden the sol-gel process (e.g. Ormocere).
- Plastics suitable for the same purpose are acrylic resin dispersions and / or Epoxy resin emulsions, which micro-fine to nano-part, reduce the flammability Substances are added. In particular, these are inorganic Substances.
- a sufficient application quantity results from the application of 20 to 300 g Dry substance of the impregnation per square meter surface of the insulation element.
- the impregnation is preferably applied to both surfaces, because both surfaces are also hydraulically setting Building adhesives, namely the adhesive mortar on the one hand and the plaster layers on the other comes into contact.
- the impregnation particles do not form any coherent Layers, but capture the individual fibers to a depth from approx. 1 to 5 mm below the respective surface area.
- the pressure-resistant plastic layer is modified Building adhesives, tile adhesives, adhesive mortars, in particular of the polymer-cement-concrete type and / or cement mortar, preferably of the epoxy-cement-concrete type consists.
- This configuration means that the pressure is applied the insulation boards with the applied adhesive layer on the facade or the adhesive layer previously applied to the wall, in particular at points highly resilient.
- the coatings are preferably in thicknesses of approx. 1 to 5 mm applied.
- the construction adhesive preferably with the aid of finely divided fibers, such as mineral fibers, textile glass fibers, metal fibers, plastic fibers, cellulose fibers or through Fabrics made of glass fibers, plastic yarns or fibers, metal springs or the like reinforced.
- finely divided fibers such as mineral fibers, textile glass fibers, metal fibers, plastic fibers, cellulose fibers or through Fabrics made of glass fibers, plastic yarns or fibers, metal springs or the like reinforced.
- the granular aggregates of the glue can also be caused by needles or columnar minerals, such as wollastonite.
- the pressure-resistant layer is preferably applied over the entire surface.
- the coating can also be applied only over part of the surface, in particular in sections.
- strip and / or plate-shaped sections on the mineral fiber shaped bodies have proven to be particularly suitable.
- a coating arranged in the middle of the insulation element is generally dispensed with. The deflection of the insulation element will then no longer take place evenly, but only in the non-coated areas.
- the deformed insulation element is given the shape of a polygon. At the same time, the shear stresses of the bond between the insulation element and the coating are considerably reduced.
- strips and / or sections of pressure-resistant materials such as fiber cement, calcium silicate, rock wool with a high bulk density, in particular between 200 and 350 kg / m 3 .
- the coating can have a tear-resistant plastic infiltrated into the surface, for example a hot glue and / or bitumen, which can be removed with weak or unbound fibers adhering to it before processing of the mineral fiber molded body. Impregnation and coating can be combined.
- the surface areas that are provided with an inorganic impregnation can be covered with an epoxy cement concrete.
- the wall-side impregnation is carried out with a thermoplastic plastic dispersion or with thermosetting plastic dispersions or emulsions.
- a fabric and / or nonwoven is fully or partially embedded.
- the fabric and / or fleece stands laterally over an edge of the mineral fiber molded body out.
- the fabric and / or fleece the primer overlaps.
- the tissue and / or Nonwoven made of plastic film, cellulose layer, in particular in the form of cardboard and / or Bitumen sheeting is formed.
- An insulation element designed according to this teaching has the advantage that after pressing the lamella plate onto the building facade and the primer can be torn off when the adhesive is put on. Not only are the fibers weak or unbound from the outset removed, but also those structural elements that were damaged during application have been. To achieve detachment, the tissue is and / or Fleece provided.
- An insulation element 1 shown in FIG. 1 for those to be applied to building facades Thermal insulation composite systems consist of a mineral fiber molded body 2, the two large, parallel and spaced surfaces 3 and 4, which are interconnected via narrow sides 5 and 6 are.
- the mineral fiber molded body 2 preferably has a right angle to the large surfaces 3 and 4 aligned fiber course.
- the insulation element 1 also has a coating 7 on the surface 3 on, the impregnation 8 and sections 9 of a pressure-resistant Layer with a high affinity for hydraulically setting construction adhesives, such as There is adhesive mortar, cement mortar or other mortars.
- An impregnation 10 is also applied to the surface 4.
- the impregnation 10 can be identical to the impregnation 8 in terms of its consistency to match.
- the impregnations 8 and 10 are preferably all in one Spray method applied to the mineral fiber molded body 2.
- the impregnations 8 and 10 are at a depth in the zones near the surface up to 5 mm of the mineral fiber molded body 2 arranged. They don't consist of flammable substances, for example from a water glass solution with low Proportions of plastic dispersion. Alternatively, silicate paint, dispersion silicate paint, Find silica sol and / or nanoparticle dispersed silica. Per 250 g of dry substance become the square meter surface of the mineral fiber molded body 2 applied to the impregnation.
- the sections 9 of the pressure-resistant layer are at regular intervals arranged on the surface 3, the sections 9 transverse to the longitudinal extension of the mineral fiber molded body 2 are arranged to extend.
- Sections 9 consist of plastic-modified construction adhesives, tile adhesives, adhesive mortars and / or cement mortars.
- the material thickness of the sections 9 of the pressure-resistant Layer is 5 mm. In the above-mentioned substances of pressure-resistant Layer are finely distributed mineral fibers embedded that the reinforcement of sections 9 serve.
- Such an insulation element 1 has a width between 400 and 600 mm and is corresponding to a lamella plate with a fiber course at right angles to surfaces 3 and 4.
- the width compared to a standard lamella plate, which is usually a width of 200 mm, the tendency to deformation of the insulation element 1 becomes in particular increased under the load of the applied adhesive mortar.
- the length of a Such insulation element 1 is between 600 and 1200 mm, where a length of 800 mm has proven to be particularly advantageous.
- the insulation elements 1 produced in this way can in any width, when leveling around the horizontal axis in the Width of the production line from z. B. 2 m. Result from this Manufacturing cost advantages. But it turned out to be useful, such to divide large-format insulation elements 1 into more manageable sizes, because large-sized insulation elements 1 in view of the cramped conditions Work scaffolds are difficult to process.
- the cut, ground or rubbed surfaces 3, 4 of the Insulation element 1 are then with a fine water jet or pressurized with air to blow away loose particles that are not bound Compress fibers and / or the supporting fibers or tufts of fibers expose.
- the surfaces 3, 4 with a Vacuum strong vacuum to remove unbound mineral fibers.
- the same goals lie in the impregnation of the surfaces 3, 4 with a tensile, preferably organic adhesive and its subsequent peeling based.
- the weakly bound mineral fibers remain on the Adhesive film stick and are thus removed.
- the surfaces 3, 4 newly created due to these treatments are pronounced unevenly formed and are then impregnated 8, 9 covers the surfaces 3, 4 for construction adhesive, adhesive mortar, plaster or to make the same well wettable on the one hand and the frictional connection on the other i.e. to decisively improve the transverse tensile strength of the composite.
- Insulating element 1 differs from the exemplary embodiment according to Figure 1 on the one hand that the impregnation 8 on the surface 3 is not is applied over the entire surface. Rather, impregnation 8 is partial infiltration the surface 3 with a tear-resistant plastic, for example with hot glue or bitumen provided. Below this tear-resistant plastic is the Impregnation 8 arranged.
- a tissue 12 is embedded, which protrudes laterally beyond the surface 3.
- the fabric 12 can be formed directly with the plastic layer 11 or, as shown in Figure 3, over the entire surface 3 of the insulating element 1 extend so that the tissue 12 additionally has a protective function for the surface 3. In both cases, the fabric 12 is one pressure-resistant layer with great affinity for hydraulically setting construction adhesives represents.
