Description

COMPOSITION FOR A LOW-SHRINKAGE PASTY FILL AND FINISH MATERIAL, PASTY FILL AND FINISH MATERIAL, AND METHOD FOR PRODUCING A FILL AND FINISH MATERIAL PASTY FIELD OF INVENTION The invention relates to a composition for a pasty filler and finishing material, a pasty filler and finishing material, and a method for producing a pasty filler and finishing material according to the respective independent claims. BACKGROUND OF THE INVENTION In the prior art, two basic types of filler materials are known for filling joints or for application to surfaces, such as walls, to smooth out any irregularities. They also function as a primer layer for applying another layer on top. Specifically, there are powdered fillers and pastes. Paste fillers have the advantage of being ready to use, while powdered fillers must be mixed with water before use. Paste fillers can be stored for months without their processing characteristics changing or deteriorating. Paste-like filling materials known in the state of the art (e.g., US 2005 / 0235878 Al) are physical drying systems comprising polymeric binders, fillers, and additives. A polymeric binder, such as polyvinyl acetate, polyethylene vinyl acetate, polyacrylate, and / or polyvinyl alcohol, is used, either as an aqueous dispersion or as a redispersible powder. The binders serve to bind the components of the filler material and adhesively bond the filler to the substrate, such as a wall or similar surface. Filler components, nodular and lamellar materials, typically of mineral origin, are used. These filler components form the structure or skeleton of the coating and thus contribute to the layer thickness and subsidence characteristics, depending on the amount of filler material added. A primary mineral filler material is natural calcium carbonate or calcium magnesium carbonate. RJ I cnn / l 7Π7 / Β / ΥΙΛΙ (dolomite). Additives can include, for example, thickening agents and biocides. Thickening agents can be cellulose-based additives, such as hydroxypropyl methylcellulose and hydroxyethylcellulose, which maintain a constant viscosity in the pasty filler material and ensure consistent processability when stored for up to a year. Biocides are added to prevent bacterial contamination and, finally, fungicides are added to prevent fungal infestation. Meanwhile, paste-like fillers are increasingly used for semi-finished surfaces, and will therefore be referred to as paste-like fillers and finishes. In this context, semi-finished means that no additional surface coating is required. However, subsequent coatings (e.g., decorative coatings) are possible. Most paste-like fillers and finishes are applied manually, for example, using a cavity. If necessary, the person using the filler and finish adds water to facilitate and improve workability. With increasing mechanization, the application of construction chemicals, fillers, and pasty finishing materials has been developed for use in processing machinery. Specifically, sprayable fillers and finishing materials have been developed that can be applied to a surface with a layer thickness of up to 3 mm and act as a substrate for other layers applied subsequently, such as wall paint or wallpaper. However, sprayable mineral-based filler and finish materials known from the prior art have the following drawbacks: When the paste filler and finish material is applied by spraying, the hydraulic atomization or airless application method is typically used. A key requirement for airless application is that the homogeneous paste filler and finish material requires reduced shear stress once it moves through the spraying equipment and nozzle during spraying. Therefore, sprayable paste filler and finish materials must be thoroughly prepared by mechanical homogenization before being applied to a surface or joint, resulting in thinning. RJ I cnn / l 7P7 / B / YILI shearing. This additional procedure leads to a substantial increase in the total processing time. Furthermore, in known prior art sprayable paste-like fillers and finishing materials, as well as in gypsum materials, organic components are generally used to ensure their mechanical workability. However, the use of organic components typically results in emissions and unpleasant odors, which limits the use of such products for interior applications. Additionally, organic components pose a critical risk with regard to fire protection. Pasty fillers and finishing materials are used to level surface irregularities and provide a homogeneous surface for additional coatings, such as decorative coatings. Many pasty fillers that are extremely suitable for use in mechanical spraying equipment either cannot provide this leveling function, thus requiring additional processing steps, or they have the aforementioned disadvantages regarding odors and emissions, or poor fire performance. As described in US patent 6,545,066, lightweight paste-like fillers and finishes contain spherical silicate products, such as microperlite, to reduce the specific gravity of the final product and provide increased surface area yield. These materials tend to thicken over several days to weeks after production and develop air bubbles during storage. This air bubble formation and thickening cause problems during machine application, particularly with the airless application method. Furthermore, in cases where pasty filling and finishing materials are used as substrate layers for subsequent decorative coatings, products with very high gloss and high drying capacity should be used. Finally, when pasty filling and finishing materials are applied to porous or mineral substrates with cavities (e.g., ready-mix concrete), these substrates exhibit increasing bubble formation on the surface. This is a major drawback, as porous or mineral substrates are very common. RJ I cnn / l 7P7 / B / YILI minerals with cavities. When applied using the hydraulic atomization method (airless application method), the paste-like filler and finish material is pressed at pressures up to 220 bar through a nozzle approximately 1 mm in diameter. The atomized spray of the paste-like filler and finish material compresses the air as it exits the nozzle and reaches the surface under pressure. In concrete, for example, the compressed air, being pushed forward, is forced into the cavities (or chip marks) of the concrete, and the paste-like filler material is placed on top of the cavities without filling them. After coating, the compressed air inside the cavities presses against the coating, resulting in the formation of bubbles. This usually occurs within the first 10 to 30 minutes after application. DESCRIPTION OF MODALITIES OF THE INVENTION Therefore, it is an objective of the present invention to provide a composition for a paste-like filler and finish material that is easily machine-processable, provides good resistance to cracking and shrinkage, exhibits only a low tendency to thicken during material storage, and, in particular, prevents the formation of bubbles on the coated surface, as explained above. It is also an objective of the present invention to provide a corresponding paste-like filler and finish material and a method for producing such a paste-like filler and finish material. This objective is achieved by a composition of a pasty filler and finishing material, comprising at least one filler, at least one binder, and additives, wherein the at least one filler has a density-dependent flowability (ffp) value of 3 to 20, preferably 4 to 15, more preferably 5 to 10, with the highest preference 6 to 8. The preferred embodiments of the invention are defined in the respective dependent claims. The composition of the invention provides pasty filler and finishing materials, which allow the use of the hydraulic atomization method (airless application method) without the formation of bubbles on the surface after coating. Therefore, it is possible to produce a surface coated with the pasty filler material of the invention without bubble formation. Furthermore, the composition of the invention provides filler materials and RJ I cnn / l 7P7 / B / YILI is a paste-like finishing material that can be used without any additional processing or preparation steps, particularly in airless spray applications. This paste-like filler and finish material is easy to work manually and provides good resistance to cracking and shrinkage. Furthermore, using an additive consisting of a mixture of liquid hydrocarbons, modified fatty acid derivatives, non-ionic emulsifiers, and silicone oil ensures excellent workability of the filler over an extended period. The aliphatic hydrocarbon components of this additive have an antifoaming / venting effect, thus eliminating air bubbles that may form during storage of the filler material. Furthermore, the amphiphilic coating of the perlite can reduce the water demand of highly porous perlite and thus minimize post-thickening while maintaining the theoretical properties of the filler and pasty finish material. The hydrophobic portion of the coating can interact with the aliphatic constituents of the filler and pasty finish material, reducing the water demand of the porous perlite and consequently post-thickening. The hydrophilic portion of the coating can interact with the polar constituents of the filler and promote material homogeneity; that is, it can prevent the separation of individual components during storage. According to a preferred embodiment of the invention, the at least one filling is a hollow spherical aluminum silicate. The term "spherical" in the context of the present invention means a very round shape, such as a billiard ball. However, even round shapes with little irregularity are considered spherical in the context of the present invention. The term "hollow" in the context of the present invention means empty, where the empty space does not include gas. In other words, the hollow spherical aluminum silicate is hollow and contains no liquids or solids in its internal space, but rather gas. This gas can be, for example, carbon dioxide (CO2) or nitrogen (N2) or any mixture thereof, for example, 70% CO2 and 30% N2. Other gases, preferably inert gases, are also possible. RJ I cnn / l 7P7 / B / YILI Furthermore, hollow spherical aluminum silicate can be characterized as being lightweight (e.g., with an average particle density of approximately 780-950 kg / m3 and an average apparent density of approximately 400-490 kg / m3), flow-free, spherical, and inert. A preferred composition may comprise from 1.0 to 10.0% by weight of the total composition, preferably from 1.5 to 8.5% by weight of the total composition, more preferably from 2.0 to 7.0% by weight of the total composition of hollow spherical aluminum silicate and / or the hollow spherical aluminum silicate may comprise aluminum oxide from 5 to 35% by weight of the hollow spherical aluminum silicate and / or silicon dioxide from 50 to 80% by weight of the hollow spherical aluminum silicate. Density-dependent flowability (ffP) describes the ability of a bulk material to flow out of a silo by gravity. In more physical terms, density-dependent flowability (ffP) can be described as the product of apparent density (pb) and flowability (ffc) (divided by 1000 kg / m³ to obtain the dimensionless term), where flowability (ffc) is the ratio of consolidation stress (σi) to compressive strength (σ0). Consolidation stress (σi) and compressive strength (σe) can be determined with a compression test: first, the bulk solid is filled, for example, into a hollow cylinder and loaded in the vertical direction (consolidation stress σi). After consolidation, the bulk solid is released from the consolidation stress, σi, and the hollow cylinder is removed.In the second stage, the consolidated cylindrical bulk solid is subjected to increasing vertical compressive stress until the bulk solid breaks at a certain stress (the compressive strength (σε)). However, other methods for determining density-dependent flowability (ffP) are known in the prior art, for example, using a ring shear tester. For instance, the density-dependent flowability (ffP) value for a hollow spherical aluminum silicate as described above is approximately 7.0, which is significantly higher than the respective value for dolomite and perlite powder, which is approximately 2.6. Therefore, the flow behavior of hollow spherical aluminum silicate as described above leads to a significant reduction in stress. RJ I cnn / l 7Π7 / Β / YILI shearing once the homogeneous pasty material in the airless application moves through the spraying equipment and the spray nozzle during spraying. In another preferred embodiment of the invention, the composition further comprises at least a second and a third filler, wherein the second and third filler of the composition may comprise at least a first and a second carbonate, wherein the particle size distribution of the first carbonate is different from the particle size distribution of the second carbonate and / or wherein the first and second carbonate are selected from a group consisting of calcium carbonate, calcium magnesium carbonate, or any mixture thereof. However, the numbering (first, second, third, etc.) may be changed.Furthermore, it should be noted that the characteristics of the D50 and D98 values ​​of the first and second carbonate are independent of their chemical constitution, which means that, for example, calcium carbonate or calcium and magnesium carbonate or any mixture thereof can be provided with any of the values ​​defined for the D50 and D98 values. Furthermore, in a preferred embodiment, the first carbonate filler can be dolomite powder (commercially available from Omya GmbH Cologne as Dolomitmehl 90) in an amount of 30 to 60% by weight of the total composition, preferably 30 to 45% by weight of the total composition, and / or the second carbonate filler can be Juraperle MM (commercially available from Eduard Merkle GmbH & Co. KG) in an amount of 5 to 25% by weight of the total composition, preferably 10 to 20% by weight of the total composition. Preferably, the composition may comprise from 35 to 85% by weight of the total composition of the first and second carbonate filler (meaning the combined weight of the first and second carbonate). An amount of 40 to 65% by weight of the total composition is particularly preferred. In a preferred embodiment of the invention, the particle size distribution of the hollow spherical aluminum silicate and the first and second carbonates can have specific values: the D98 value for the first carbonate can be from 70 to 120 µm, preferably from 80 to 100 µm, and / or the D98 value for the second carbonate can be from 120 to 200 µm, preferably from 150 to 170 µm. Furthermore, the first and / or second carbonate RJ I cnn / l 7P7 / B / YILI can have a D50 value of 10 to 30 μm, preferably 15 to 25 μm. In addition, hollow spherical aluminum silicate can have a D50 value of 90 to 200 pm, preferably 100 to 180 pm and / or a D98 value of 150 to 400 pm, preferably 170 to 250 pm. The D50 and D98 values ​​to describe the particle size distribution of (bulk) materials are known to the expert in the art. According to the present invention, the composition may comprise at least one binding agent. The at least one binding agent may be selected from the group consisting of poly(ethylene-vinyl acetate), polyvinyl acetate, polyacrylate, polyvinyl alcohol (PVOH), or any combination thereof, preferably poly(ethylene-vinyl acetate), polyvinyl alcohol (PVOH), or any combination thereof. The at least one binding agent may be added to the composition as an aqueous dispersion or as a redispersible powder. Preferably, the at least one binding agent may be contained in the composition in amounts of 0.1 to 20.0% by weight of the total composition, preferably 1 to 15.0% by weight of the total composition, more preferably 1.5 to 10.0% by weight, with the highest preference being 2 to 5% by weight of the total composition. A preferred composition according to the present invention may further comprise a fourth filler, wherein the fourth filler is selected from a group consisting of sepiolite, attapulgite, talc, vermiculite, montmorillonite, illite, kaolinite, or hectorite, preferably attapulgite or sepiolite, and / or wherein the composition comprises from 0.1 to 10.0% by weight of the total composition, preferably from 0.1 to 5.0% by weight of the total composition, more preferably from 0.1 to 2.0% by weight of the total composition of a fourth filler. Another preferred composition according to the present invention may further comprise cellulose, preferably modified cellulose, more preferably modified cellulose selected from the group consisting of 2-hydroxyethylmethylcellulose, hydroxypropylcellulose, ethylcellulose, methylcellulose, methylethylcellulose, carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose, or any combination thereof, most preferably hydroxyethylcellulose, hydroxypropylmethylcellulose, or any combination thereof.

Furthermore, the composition of the invention may comprise at least a fifth filler, wherein this fifth filler is selected from the group consisting of calcium sulfate dihydrate, calcium carbonate, calcium magnesium carbonate, and perlite, preferably perlite, and / or wherein the composition may comprise from 1.0% to 40% by weight of the total composition, preferably 1.0% to 20% by weight of the total composition, more preferably 1.0% to 10% by weight of the total composition, most preferably 2.0% to 5.0% by weight of the total composition of at least a fifth filler. Furthermore, the perlite mentioned above may be micronized and expanded perlite with a D98 particle size of less than 200 µm, preferably less than 100 µm. The average particle size is determined by averaging the linear intersections of the grain boundaries. Specifically, the average D50 particle size is between 20 and 80 µm, preferably between 40 and 60 µm. Additionally, the perlite mentioned above may have an amphiphilic coating. The perlite can help reduce weight to provide a pasty filler material. Especially preferred, the composition comprises 2.0 to 5.0% by weight of micronized and expanded perlites. The amphiphilic coating of the pearlites preferably comprises alkoxy-modified alkylsilicone resins, especially aminoalkyl-substituted polydimethylsiloxanes of formula (CiHeOSiju. where n is preferably from 30 to 300. The alkoxy-modified alkylsilicone resins of the amphiphilic coating improve the flow characteristics of the sprayable filler material. This allows for reduced shear stress, enabling continuous material delivery, such as an airless method, without prior mechanical homogenization of the material. Once the material is on the surface, the shear stress increases again, allowing for a comparatively high application thickness. A preferred composition according to the present invention may comprise, in addition to 0.1 to 10% by weight of the total composition, preferably 0.1 to 0.4% by weight of the total composition, an additive consisting of a mixture of alkoxylated non-ionic compounds, compound non-ionic fats, and hydrophobic silica.

More preferably, the fatty compounds can be fatty acids. According to another preferred embodiment of the invention, the composition may further comprise biocides as additives. The biocides added to the composition may be based on 2-methyl-1,2H-thiazol-3(2H)-one (MIT) and / or 2-benzisothiazol-3(2H)-one (BIT). The composition may preferably comprise from 0.1 to 2% by weight, and preferably from 0.1 to 0.4% by weight, of biocides. The pasty filling and finishing material may preferably comprise water in quantities of 20 to 60% by weight, preferably 30 to 50% by weight of the total composition. According to the present invention, a paste-like filler and finish material, in particular a physically drying sprayable filler and finish material, is also provided, manufactured from the composition specified above. The paste-like filler and finish material of the invention provides the advantages already described above in relation to its composition. Preferably, the specific gravity of the paste-like filler and finish material is less than 1.6 kg / L. In particular, below 1.5 kg / L is preferred. This paste-like filler and finish material is considered a medium-weight paste-like filler and finish material. According to another preferred embodiment of the present invention, a layer thickness of 1 to 3 mm immediately after application will shrink to layer thicknesses of 80% to 90%, preferably 83% to 87%, after drying. From the art RJ I cnn / l 7P7 / B / YILI above it is known that a layer thickness of 1 to 3 mm of a prior art composition shrinks to a layer thickness of approximately 65% ​​after drying. Therefore, the present invention shows a significant reduction in the shrinkage of the dry composition layer. The present invention also provides a method for producing paste-like filler and finishing material, in particular medium-weight paste-like filler and finishing material as specified above. The method is based on a two-stage process, according to which, in a first stage, the dry components are homogenized, and in a second stage, the homogenized dry components are added to the aqueous or water-dilutable components. The dry components comprise fillers, perlite, and optionally other dry additives and / or dry binding agents. The perlite may have an amphiphilic coating. The aqueous or water-soluble components may comprise an additive consisting of a mixture of liquid hydrocarbons, modified fatty acid derivatives, non-ionic emulsifiers, and silicone oil, and optionally other liquid additives and / or liquid binding agents. Using the method of the invention, paste-like filler and finishing materials can be provided that have the advantages described above. Ideally, the first and second stages of the two-stage process can be performed in parallel for more than 80% of the processing time. Therefore, parallel processing saves processing time and thus makes the method more cost-effective. The resulting paste-like filler and finish material can generally be applied by all methods known in the prior art, for example, with the aid of mechanical tools or by mechanical processing. Mechanical processing is preferred. The following examples show further details and features of the invention which are for clarification purposes only and do not in any way restrict the scope of protection conferred by the claims.

A sprayable, paste-like filler and finish material having a composition according to the present invention provides a homogeneous substance that still exhibits comparatively low shear stress even at high shear rates. This enables continuous material flow for efficient spray application performance. The spherical shape of the hollow spherical aluminum silicate results in better penetration into surface defects compared to other hollow silicates. This is particularly noticeable on concrete surfaces made of cast-in-place concrete or sophisticated concrete with surface defects, where capillary forces are active and therefore a lower surface tension is required (see figures).Furthermore, the combination of the first and second carbonate, which differ in their particle size distribution, has the effect that the thickness achieved in the wet state only sinks very little when it dries. The compilation of particle size distributions of the first and second carbonate as well as the hollow spherical aluminum silicate surprisingly shows a lower tendency to agglomerate, so that less post-thickening occurs and the processing properties are assured for a longer time. BRIEF DESCRIPTION OF THE DRAWINGS Figures 1a, 1b show a state-of-the-art pasty filler and finishing material applied to a bubble-forming concrete surface and Figure 2 shows an inventive pasty filler and finishing material carried over a concrete surface without bubble formation. For Figures 1a, 1b, and 2, the pasty filler and finish material is sprayed onto defective concrete (commercially available concrete elements, e.g., from Bosch Beton GmbH & Co. KG) using the airless application method described above. In Figures 1a and 1b, state-of-the-art pasty filler and finish materials were used: Figure 1 shows a regular weight example according to Table 1, and Figure 1b shows a lightweight example according to Table 1. In Figure 2, a pasty filler and finish material of the invention was used according to Table 1. In Figures 1a and 1b, the pasty filler and finish materials cover the defects without filling them. Therefore, bubble formation occurs from the compressed air, as explained above. In Figure 2, with the pasty filler and finish material of RJ I cnn / l 7P7 / E / YILI of the invention, the defects were filled and, therefore, bubble formation is not visible. The photographs of the three coated surfaces were taken 24 hours after application. Furthermore, the sprayable paste filling and finishing material having a composition according to an embodiment of the present invention also provides, with a layer thickness of 1 to 3 mm, a homogeneous surface for, optionally, the following decorative coatings. Furthermore, the post-thickening, as indicated by the viscosity difference, is reduced to approximately 1 / 3 for the paste filler according to the invention compared to the paste filler and finish material according to the prior art. Both the paste filler and finish material according to the invention and the paste filler according to the prior art comprise micronized and expanded pearlites. The pearlites used in the filler of the invention are treated with an amphiphilic coating, whereas the pearlites used in the prior art filler do not have an amphiphilic coating. The amphiphilic coating was achieved with a silicone microemulsion comprising functional amino-alkyl polydimethylsiloxane. Declared (measured) values, such as a commercially available carbonate stating a D50 value of 20 qm, are considered to be approximately 20 qm, depending on the accuracy of the measurements.
