Definitions
- the invention relates to a method for heat and / or sound insulation Building wall, in particular an outer wall of the building, with the insulation elements from mineral fibers bound with a binding and / or impregnating agent, for example stone or glass wool, in particular heat and / or sound insulation panels, preferably mineral fiber lamella plates with a fiber course perpendicular to their large surfaces, at least with a construction adhesive on the Building wall to be attached.
- the invention further relates to a device for Carrying out the method, in particular for applying a liquid coating on at least a large surface of an insulating element Mineral fibers.
- Insulating elements are made from mineral wool, for example from stone or glass wool made and consist of glassy solidified fibers.
- the chemical composition The rock wool is made up of oxides of the alkaline earths of calcium and of magnesium dominates.
- Other network-converting oxides are oxides of divalent and trivalent iron are present, while silicon oxide and aluminum oxide that actually form glass scaffolding.
- network dominate Oxides sodium, potassium and boron.
- Stone wool is made from a melt mainly on so-called cascade fiberizing machines manufactured. These machines are mostly with four roller-shaped ones Equipped bodies that are staggered. The Rollers rotate at high peripheral speeds, increasing from roll to roll about their horizontal axes. The melt is on the mantle of the first Roll passed, distributed there and forwarded to the following roll. From one thin melt layer, droplets dissolve, which either become fine particles, namely very short fibers are pulled out or ideally a ball form. The output on fibers is only approx. 50%. The thrown away radially Particles are redirected by coaxially directed air flows, merged and in the direction of an air-permeable conveyor belt directed.
- the heavier non-fibrous particles separate on the way there of fiber flakes with fine non-fibrous constituents enclosed therein.
- the fiber mass collected on the conveyor belt therefore contains approx. 25 contain up to approx. 30% by mass of non-fibrous particles.
- the diameter of the usual Fibers is approx. 2 to 3 ⁇ m, the lengths only a few millimeters, only a few Fibers reach longer lengths.
- Binders required for binding the fibers are dissolved in water, in each case passed through hollow axes of the rollers and as a result of the rotation of the rollers, the high turbulent flow and the sudden evaporation of the water dispersed in the finest droplets, which are not yet agglomerated knock down individual fibers. Via additional nozzles on the circumference of the rollers additional amounts of binder can be introduced and overall the distribution the amount of binder in the fiber mass can be improved. But there the fiber mass flows naturally overlap and in the area of the feed the melt is significantly disturbed, is the distribution of the binder in the Fiber mass not even. In the area of the first roller at all No binders added, so that the fibers that are created there unintentionally stay free.
- the fibers are treated with water repellents, for example oil, supplied with neither the amount of binding nor Water repellents are usually sufficient to make the fibers as desired to link with each other point by point or the entire surface of the fibers moisten with oil.
- water repellents for example oil
- the non-fibrous components are not glued to the fibers.
- One of The reason is their compared to the fibers with a favorable surface-volume ratio lower cooling speed, so that impinging binder droplets Dry too quickly and the resins will react.
- fillers are also ground Fibers blown in from downstream processing stages or from faulty batches. These fibers are also only mechanically integrated in the fiber agglomeration and can with regard to strength properties, in particular the tensile and shear strengths of the insulating materials made from the fibers make no contribution.
- the fibers impregnated with binder and oil are collected into an approx. 2 to 5 cm thick, approx. 2 to 4 m wide, loose so-called primary fleece with a weight per unit area> approx. 200 to 300 g / m 2 and fed to an oscillating double belt, which the primary fleece is deposited on a second conveyor belt arranged transversely thereto, in each case overlapping in layers.
- approx. 4 to approx. 12 layers are staggered one above the other in the endless fiber web produced in this way.
- the endless fiber web is compressed to the desired thickness using pressure tapes or rollers arranged one behind the other.
- the bulk density of the endless fiber web is set by the compression in connection with the basis weight predetermined by the conveying speed of the fiber web.
- the fiber web is fed to a hardening furnace, in which means through the fiber web hot air drawn through evaporates the existing residual moisture and that Binder hardened.
- the approx. 2.03 to approx. 2.10 m in many production lines wide endless fiber web has irregularly shaped side surfaces.
- the fiber web is therefore trimmed on both edges and in additional if necessary Longitudinal lines divided. These are then cut by cross saws in the desired length or width of the insulation elements from the endless fiber web separated.
- the insulation elements are based on the rigidity or flexibility, for example A distinction is made between rollable insulation felts and insulation boards.
- the orientation of the individual fibers in the insulation elements and the bulk density influence not only the fiber dimensions, the type of melting material, the amount of non-fibrous components and the binder content, but also the thermal conductivity of the mineral wool insulation elements.
- the thermal conductivity increases with bulk densities below approx. 25 kg / m 3 and at approx. 150 kg / m 3 to above approx. 0.04 W / m K.
- the thermal conductivity drops to approx. 0.032 W / m K. The flatter the fibers are to the large surfaces of the insulation elements, the lower the thermal conductivity.
- the compressive stress of the insulation elements consequently increases when the fibers are in a steep position or even at right angles are arranged to the large surfaces.
- insulation boards are subjected to greater mechanical loads in practice through the described compression of the impregnated endless fiber web in the vertical direction with simultaneous compression in the horizontal direction shaped.
- the fibers or tufts of fibers become very intensive with one another folded so that the general orientation towards the large surfaces the fibrous web takes place. With this deformation, the fibers lie immediately areas relatively flat to the large surfaces, so that For example, the maximum achievable transverse tensile strength in the two near the surface Zones is significantly smaller than in the central area of the insulation board. Around To achieve a higher transverse tensile strength, the two are therefore close to the surface Zones far enough away that the steeply stored fibers reach into the Surfaces are sufficient.
- the unfolding of the primary fleece only has an influence on the structure of the fiber web in the longitudinal direction of production. At right angles, the fibers are almost horizontal aligned. Insulation boards made from this therefore point in this direction a tensile strength that is several times higher than in the longitudinal direction of production.
- the primary fleece is wrapped around a horizontal one Unfolded axis and pressed against these vertically positioned layers.
- the zones near the surface are separated with a thickness of approx. 10 to 20 mm.
- the insulation boards produced in this way can be So for example in 2 m side length and any length in Production direction can be separated from the endless fiber web.
- Large format Insulation boards are preferred for the production of sandwich elements used with double-sided sheet metal cladding of the elements. Such insulation boards are known for example under the name "Conrock".
- Another variation of the strength and usage properties of upset or suspended insulation boards is to close the surface Zones with flat fibers from the impregnated endless fiber web to lift off in a web shape, to compress them extremely high and the compacted Then reunite the partial web (s) with the fiber web.
- the connection the fibrous web with the compacted partial webs takes place through the existing one Binder or by additional binders, if necessary also by pronounced Adhesive sprayed between the fiber web and the partial webs becomes.
- Very high transverse tensile strength values are obtained if the longitudinal and Height compression of intensively unfolded insulation boards in the longitudinal direction of production cut into slices and rotated so that the cut surfaces large and supporting surfaces of an insulation element form.
- insulation sheets in the required bulk density of approx. 200 mm in height can be manufactured Stripes only about 200 mm wide.
- Such insulation boards are because of extreme ratio of, for example, 1.2 m length x 0.2 m width slats called.
- the fibers of these insulation boards are largely perpendicular to the large surfaces oriented .. Several slats can become slat plates be put together.
- the bond between the fibers or The fiber bundle is small, so that the slats are flexible and e.g. on curved Surfaces can be glued on.
- Mineral wool insulation elements are used in so-called thermal insulation composite systems used.
- a composite thermal insulation system is mostly on external walls of buildings to reduce transmission heat losses Sound and fire protection reasons applied as well as to improve the appearance. It consists of an insulation layer that fully or on the outer wall is partially glued on and optionally additionally by anchored in the wall Screws or the like is held. Rail systems are an alternative known with which the insulation layer is fixed, using an adhesive as an auxiliary anchor and serves as a spacer or abutment. The insulation layer will then with a reinforced base layer of mineral or synthetic resin plasters covered. Fabrics made of tear-resistant glass fibers or serve as reinforcement also short fibers distributed in the plaster layer.
- This solid and the insulation layer protective base layer is covered by a top layer, which as another Weather protection layer serves and essentially the appearance of the thermal insulation composite system or the outer wall.
- a top layer which as another Weather protection layer serves and essentially the appearance of the thermal insulation composite system or the outer wall.
- Stone wool insulation materials suitable for use in thermal insulation composite systems contain approx. 3.5 to approx. 5.0 mass% of the mixture of thermosetting phenol-formaldehyde-urea resins and approx. 0.2 mass%, at most up to approx. 0, 4% by mass of high-boiling mineral oils.
- the bulk densities of the insulation boards in the area of the thermal conductivity group (abbreviated WLG) 040 according to DIN 4108 are approx. 135 to 180 kg / m 3 , preferably approx. 145 to 160 kg / m 3 and is approx. 90 to 120 for boards of WLG 035 kg / m 3 lowered.
- WLG thermal conductivity group
- the bulk density of the cover layer (s) is increased to approx. 160 to 200 kg / m 3 , while the core area of the insulation boards of the WLG 040 is increased to approx. 120 to 140 kg / m 3 is compressed.
- the bulk density of the top layer (s) is reduced to approx. 140 to 180 kg / m 3 , that of the core area to approx. 80 to 100 kg / m 3 .
- the characteristic transverse tensile strengths drop from over approx. 17 kPa (WLG 040) to only approx. 5 kPa (WLG 035).
- a transverse tensile strength of> 100 kPa is achieved with an average bulk density of approx. 90 kg / m 3 (WLG 045), and at least with an average bulk density (WLG 040) of approx. 75 kg / m 3 still achieved a transverse tensile strength of approx.> 70 kPa.
- the transverse tensile strength drops to> approx. 50 kPa. With a lower bulk density, the lamellas or lamella plates become more and more flexible. In the gross density range of approx.
- the main economic advantage is that the specific Material use compared to the insulation boards with laminar fiber course clearly can be lowered.
- the slats or slat plates may continue to can be glued to building heights of 20 m without additional anchoring, which means a further saving in processing time and material costs.
- cross-tensile strengths are currently being granted for lamellas or lamella plates of> 80 kPa, compressive strengths> 40 kPa and shear strengths> 20 kPa are required.
- the thickness of the insulation layer in the general building inspectorate approved Thermal insulation composite systems are at least 4 cm and can be up to a maximum approx. 20 cm and in exceptional cases the passive houses, which are not built too often can be increased to 40 cm. Common thicknesses are currently around 8 to 12 cm. The so-called on the inside of windows and door openings Reveal plates are limited to approx. 2 or 3 cm, not to the openings restrict too much.
- Insulation boards with or without compacted surface zones are fastened with the aid of insulation holders, which have a mostly circular board with openings and a dowel.
- the insulation holders are preferably placed on the insulation layer.
- the panels must have a diameter of at least 60 mm and, for insulation panels with cover layers of, for example, 90 or 120 to 140 mm.
- fastening through a reinforcement mesh of the base layer is much more effective and secure for the stability of the thermal insulation composite system. This approach is not very popular with the craftsmen because of working on the fresh base layer.
- the number of insulation holders per m 2 of area is higher in the edge areas of a building than in the middle areas in accordance with the wind suction loads according to DIN 1055. With increasing building height, the number of required insulation holders naturally increases.
- the adhesive makes a significant contribution to safety and the usability of the thermal insulation composite system. Self, if the adhesion is reduced, the positive connection prevents it from slipping off easily of the thermal insulation composite system under own load. The non-positive on the adhesive applied to the insulation boards stiffen them and thus hinder them cracks in the plaster layers on the outside.
- the adhesive is applied either all around on the edge of the insulation board plus a bit or several glue spots in the middle with a total area of at least 40% or by applying a full surface to the insulation board and / or the substrate Adhesive layer.
- the adhesive for example an adhesive mortar, must be used as a so-called Press filler can be worked into the surface.
- Press filler can be worked into the surface.
- a second Work step is the "fresh in fresh" glue all over the insulation board apply.
- This adhesive technique results in the surface properties of the Insulation boards have certain requirements for the adhesive.
- the flat to be glued to Surface fibers form a highly effective fine filter, the Filter resistance at appropriate pressure due to the compression of the fibers even increases.
- the fiber mass is also not capillary active.
- the in the used liquid or the finest dispersed therein Particles have to be under relatively high pressure as he slants through the edge of a employed trowel or by pressure rollers with small diameters in the Fiber mass are pressed.
- Fiber mass areas that consist of binder-free or low-fiber bundles or much unbound Containing recycled fibers are significantly more compressible than neighboring ones connected fibers. They become incompressible by being pulled over them Layer of adhesive squeezed and go after releasing the pressure back to the initial state. They press the glue and also thin layers of base plaster applied on the outside, so that there are slight bulges form.
- the penetration depth is selectively a maximum of approx. 2 mm, in the area ⁇ 1 mm.
- the total layer thickness within and above the fiber mass Layer of adhesive is less than about 1 mm thick. So that the glue on at all or adheres to the fiber mass, it must have surface-active and adhesive components and have sufficient internal cohesion.
- the adhesive In addition to the pure adhesive and cohesive properties, the adhesive also has to Have filling capacity. That is necessary to remove the unevenness of the surfaces the insulation boards as well as those of the subfloor.
- the elevations thus formed on the surface usually a height of about 0.5 to 1 mm.
- the walls on which the insulation elements are to be glued face Bumps on. Permissible and thus usual bumps are in DIN 18202 Table 2 listed. In the case of plastered walls, measuring point distances of 3 m, corresponding to floor heights of up to 8 mm. The general building inspectorate approvals stipulate that with With the help of adhesive layers, unevenness ⁇ 2 cm may be compensated. at Larger bumps have to be applied beforehand just thicker insulation elements are glued on. The glue must be highly viscous Form mass that adheres to the interfaces on the one hand and is sufficient has high intrinsic viscosity so that it does not Insulation boards expire or this falls off. On the other hand, the adhesive may the service life of maybe thirty or more years under load plastically deformed.
- the adhesives are based on hydraulically setting port-land, Alumina or metallurgical cements, highly hydraulic limes alone or in mixtures with each other, from inert granular aggregates, such as Quartz sand, limestone, marble, alumina, or from latent hydraulic aggregates, such as trass, pozzolana, blast furnace slag, power plant ash with appropriate stimulators, such as hydrated lime.
- inert granular aggregates such as Quartz sand, limestone, marble, alumina
- latent hydraulic aggregates such as trass, pozzolana, blast furnace slag
- power plant ash with appropriate stimulators, such as hydrated lime.
- the substances mentioned can be found in the most diverse mixtures and different proportions in each Glue included. Through an appropriate mix and gradation of the grain sizes, supple masses can be produced, but based on do not adhere to the hydrophobic surfaces of the insulation elements and Slightly tear open in thin layers.
- the adhesive is usually dispersions or emulsions made of thermoplastic Plastics, synthetic rubber latices or dispersions of thermosetting Plastics such as polyester, epoxy resins, silicone resins are added. These emulsions or dispersions mostly contain surface-active substances, which additionally has sufficient wettability of the surfaces of the Effect insulation elements.
- Limes, slags and ashes must be saponifiable his.
- Particularly suitable and also inexpensive plastic additives are for example methyl acrylates and methyl methacrylates.
- adhesives which in principle correspond to the definition of an adhesive according to DIN 16920, i.e. through surface adhesion and combine inner strength (adhesion and cohesion). It will uses mortar, dry mortar, adhesive mortar according to DIN 16920, plastic-modified Mortar, synthetic resin mortar, adhesive, construction adhesive, tile adhesive, Panel glue, insulation glue, ceramic glue, pasty glue or the like. With these meaningful names, the composition, grain sizes, Plastic type and proportions, condition, etc. vaguely differentiated.
- the press filler is a exhausting and time-consuming activity which, with thermal insulation composite systems built up with mineral wool insulation elements, incurs additional costs compared to, for example, hard foam insulation boards.
- one or both large surfaces of the insulation boards, in particular the lamella boards are provided with an adhesion-promoting layer.
- silica sol is used to impregnate the surface of the insulation boards used. These with surface-active and possibly foam-forming Substance-containing solution is foamed with the addition of air and can therefore be easily spread on the insulation boards. After this Collapse of the foam bubbles and drying essentially remain fine particles sitting on the tips of the fibers that are not connected Form a layer. These particles do not sit firmly on the surfaces of the Insulation boards so that they can be removed by rubbing them lightly.
- a second group of adhesion-promoting coatings namely primers with Coating effects are based on or are identical to dispersion silicate paints and contains a silicate paint, which is made of potash water glass as a binder according to DIN 18363 and pigments and fillers resistant to potassium silicate.
- a silicate paint which is made of potash water glass as a binder according to DIN 18363 and pigments and fillers resistant to potassium silicate.
- organosilicate paint or as dispersion silicate paint The Pigments or pigment mixtures are used for coloring and provide opacity and weather resistance.
- Fillers are, for example, calcite, Chalk, or marble powder with average particle sizes around 1 to 3 ⁇ m, quartz powder approx. 2 to 6 ⁇ m), talc (approx. 10 ⁇ m), Al-K silicate (approx. 14 ⁇ m); Muscovite mica, a Al-Mg-K silicate with a mean diameter of approx. 10 ⁇ m.
- acrylate or PUR thickeners bentonites, celluloses), titanium dioxide, calcite 2 ⁇ m, calcite 1 ⁇ m, talc 9 ⁇ m, precipitated silica SiO 2 , acrylic-styrene dispersion, defoamer based on mineral oil, potassium methyl siliconate, aromatics-containing film-forming aid, further film-forming aid, stabilized potassium water glass, paraffin find ,
- the dispersion silicate paint is sprayed onto the surface of the insulation board, in particular the lamella board, with a relatively high pressure, which in turn is conveyed under the spraying device at a relatively high speed.
- the spray angle is relatively wide, so that only very fine paint particles hit the surface of the insulation boards with a low momentum. Due to the plastic deformation of the droplets and the elastic behavior of the fiber tips, the local penetration depth of the coating is not greater than approx. 0.2 mm, but in practice the dispersion silicate paint is only clod-like with layer thicknesses of approx. 0.1 to approx. 0 .4 mm only on the fiber tips.
- the insulation panels are dried with radiant heaters immediately after the dispersion silicate paint has been sprayed on, which further reduces the adhesion due to the strong shrinkage after the crystal water has been expelled from the water glass. In extreme cases, the coatings chalk out after bonding, so that optimal adhesive tensile strength is not achieved.
- the bond to the surfaces of the insulation elements is similarly weak, if so-called adhesive mortar can be applied.
- adhesive mortar can be applied.
- These are initially in a thin layer in the form of a kind of press filler and applied continuously then with max. 4 - 5 mm thick beads made of so-called adhesive mortar covered.
- the reaction times are much longer than with the dispersion silicate paints hardness is not higher.
- Reinforced coatings with reinforcement are known from the prior art known on insulation elements. These coatings are due the long curing times of the hydraulic binders are relatively expensive and therefore not able to compete.
- adhesion-promoting coatings are carried out on systems which is a significant expense for investments in buildings and facilities require and costs, for example, for drying the coatings cause.
- the cost of the adhesive coatings themselves are also not insignificant, without an optimal result.
- the insulating elements are fixed with a liquid binding and / or impregnating agent for a completely adhesion-promoting impregnation immediately before they are attached to the building wall on at least a large surface and / or in a depth range below the large surface of the mineral fibers are coated.
- An essential idea of the invention is therefore the application of the liquid binding and / or Impregnation agent immediately before fastening the insulation elements on the building wall, so that on expensive factory or else site-side pre-coatings can be dispensed with.
- the binding and / or impregnating agent it is necessary for the binding and / or impregnating agent to be liquid, to easily insert it into insulation elements with a laminar structure to be able to, in which, as described above, a filter effect in particular arises when pressure is applied to the surfaces to be coated.
- the binding and / or impregnating agent must be designed to impart adhesion to allow immediate processing after coating.
- the invention thus provides that a complete and adhesion-promoting Impregnation of all mineral fibers and simultaneous anchoring of all in mineral fibers lying on the surface for optimal power transmission a liquid binding agent and / or impregnating agent is introduced. With this deep-acting binding and / or impregnating agent are all unbound or only incompletely linked mineral fibers.
- the binding and / or impregnating agent up to a depth of up to 10 mm, in particular between 1 and 5 mm below the large surface area is introduced.
- This can also be done by cutting, Grinding or rubbing caused mechanical malfunctions in the insulation element be collected in such a way that no excessive amount of mineral fibers is released becomes.
- the binding and / or impregnating agent can also be referred to as a primer as far as this primer is the adhesion-promoting impregnation of the surface and ultimately also enables the coating effects, but primarily not be sought.
- the binding and / or impregnating agent is optimal in this way applied that the fiber tips of the individual mineral fibers essentially remain free of binding agents and / or impregnating agents, so that on the plate or on the building wall applied adhesive or an applied on the outside Clean the ends of the mineral fibers, but better still larger sections of whole Mineral fibers may not include the binding and / or impregnating agent or are only slightly covered.
- the liquid binding and / or impregnating agent goes in the process according to the invention with the construction adhesive or an external plaster an intimate connection and builds the layers of construction adhesive or Exterior plaster into your own structure.
- Dispersions are suitable as binding agents and / or impregnating agents Homopolymers, copolymers or terpolymers suitable for this purpose, such as, for example Methyl acrylate, n-butyl acrylate, ethyl acrylate, 2-ethylhexacrylate, methyl methacrylate, Ethylene, vinyl propionate, vinyl acetate, vinyl chloride, styrene or the like used.
- Copolymers and terpolymers are made from two or three different ones Monomers composed to, for example, the hardness, the saponification resistance, to control water intake or the like.
- the dispersions usually contain protective colloids, emulsifiers, auxiliary monomers, Plasticizers and the like.
- neoprene latices have been shown to be impregnating agents. These can be, for example, with kaolin, metakaolin or with others Fillers can be filled, with particle sizes ⁇ 2 microns being shown to be advantageous to have.
- a Dispersion silicate paint can be provided.
- modified dispersion silicate paints compared to the standard recipes, for example, less Thickeners and less to no fillers and beyond few pigments, such as rutile, iron oxide, kaolin, metakaolin, talc, Wollastonite, aluminum hydroxide or the like for particle sizes ⁇ 2 ⁇ m contain.
- composition of such a modified dispersion silicate paint is based on the fact that the finest particles together with the liquid penetrate into the insulation element, also separate if necessary, i.e. the liquid penetrates deeper than the fine particles, while the coarser ones Particles are filtered out on the surface. Because here coating effects The need for fillers is only sought to a very small extent less than with closed coatings or paint coats.

Abstract
Description
Die Preßspachtelung ist eine kräftezehrende und zeitraubende Tätigkeit, welche mit Dämmelementen aus Mineralwolle aufgebaute Wärmedämmverbundsysteme im Vergleich zu beispielsweise Hartschaum-Dämmplatten mit zusätzlichen Kosten belastet. Um eine schnelle Verlegung und einen sicheren Halt zu gewährleisten, wird eine oder werden beide großen Oberflächen der Dämmplatten, insbesondere der Lamellenplatten mit einer haftvermittelnden Schicht versehen.
Bei der Auswahl der Stoffe oder Mischungen, die hierfür geeignet sind, wird berücksichtigt, dass die Baustoffklasse "nichtbrennbar, Baustoffklasse A1 nach DIN 4102" nicht gefährdet wird, da diese Klassifizierung ein wesentlicher Verkaufsvorteil gegenüber den als "schwer entflammbar, Baustoffklasse B1 n. DIN 4102" klassifizierten Hartschäumen aus beispielsweise expandiertem Polystyrol darstellt. Die Klassifizierung "schwer entflammbar" ist in diesem Zusammenhang völlig irreführend, da sie nur dadurch zustande kommt, weil sich der Baustoff durch Wegschmelzen der Einwirkung einer Flamme entzieht. Im realen Brandfall aber tropft die Schmelze zumeist in die Flammen und fördert das Brandgeschehen oder zündet die entstehenden dichten toxischen Gase durch.
