Description

[0001] The invention relates to a method for applying a Solvogel containing an application material to the surface of a body as a polishing, waxing or varnishing agent, comprising at least one framework structure consisting of a gelator structure or a gelator polymer structure, wherein the framework structure breaks open by a normal force generated by movement along the surface and the application material contained in the Solvogel is released onto the at least partially rough body, the roughness of which is in the range of Ra ≥0.025 µm.

[0002] Numerous tools have been designed for applying a substance to a surface. These tools are capable of reversibly binding the substance, such as a liquid, and distributing it evenly. For example, in the case of a brush, sponge, or cloth, reversible binding to the tool occurs through adhesion or capillary forces. When the tool comes into contact with a surface, if the capillary action or adhesive force emanating from the workpiece exceeds the force holding the liquid in the tool, some of the liquid will transfer to or onto the surface. As long as a balance of forces exists and a continuous flow of the liquid physically bound in the tool is ensured, the application will be even.

[0003] A disadvantage of the aforementioned tools is that, in most cases, the amount of liquid dispensed is significantly dependent on pressure and position, as the tools are highly deformable or compressible. This deformation or compression alters the force balance described above, resulting in uneven application to the surface. This is particularly noticeable with manual application.

[0004] Furthermore, with low viscosity of the liquid and insufficient holding forces, the effect of gravity and, if applicable, the acceleration force of the tool movement on the liquid is sufficient to cause it to leak out at the lower edge of the tool (droplet formation) or be flung out (splattering). Thixotropic substances, which include most varnishes and paints, demand a high degree of motor dexterity from the user.

[0005] Furthermore, at least with sponges and cloths, liquid is also squeezed out on the side facing away from the workpiece, which is also undesirable.

[0006] Finally, precise application with the aforementioned manual tools is only partially possible, as the applied liquids must be mobile due to the application method. This can lead to problems, especially with highly fluid materials, poor wettability, and difficult-to-work transitions. Ultimately, at least in the case of a brush, the amount of liquid temporarily held in it is significantly less than the total volume of the tool.

[0007] Solvogele are known from engineering, as they exhibit dendritic structures with a high capacity for gases, liquids, and solids. In a subsequent step, these solvogele can be produced as aerogels by removing the liquid between the dendritic structures from the fibril-like network, for example, by freeze-drying, and allowing air to flow into the spaces between them.

[0008] Many solvogele are produced using the sol-gel process as nanostructured open-pore solids from many inorganic materials, such as silicon dioxide or titanium dioxide.

[0009] A typical Solvogel process is described, for example, in WO 02 / 34 671 A1, according to which a metal oxide such as TMOS or TEOS is hydrolyzed with an alcohol and a hydroxide / acid is added as a catalyst and gelled.

[0010] Furthermore, DE 10 2013 205 364 A1 describes how Solvogel structures can be formed within a solid elastomer structure in order to release a functional material, for example a liquid or a wax, onto a photoactive surface by means of diffusion.

[0011] In the article by Liu, S.; Wie Y.; Zhou, C.: Solvents effects in the formation and viscoelasticity of DBS organogels. In: Soft Matter, 2013, 9, pp. 864-874. DOI: 10.1039 / c2sm2703g, the gel behavior of dibenzylidene sorbite (DBS) in various solvents is investigated using rheology, optical microscopy, and transmission electron microscopy. Among other things, liquid paraffin was used as a solvent to form a sol-gel.

[0012] Furthermore, Chen, W.; Yang, Y.; Lee, CH; Shen, AQ: Confinement Effects on the Self-Assembly of 1, 2, 3, 4-Di-p-methylbenzylidene Sorbitol Based Organogel. In: Langmui, 2008, Vol. 24, pp. 10432-10436, describes the production of sorbitol-based sorbitol gels.

[0013] From the article by Esposito, C.; Kirlov, P.: Preparation, Characterization and Evaluation of Or-ganogel Based Lipstick Formulations; Applications in Cosmetics. In: Gels, 2021, 7, 97, pp. 1-15; Supplementary Information, https: / / doi.org / 10.3390 / gels 7030097, the use of solvogels based on DBS or 12-HSA gelators is known, which are heated together with petrolatum oil, castor oil and almond oil, mixed with beeswax and pigments, cooled and can subsequently be used as lipstick.

[0014] Finally, the article by Suzuki, M.; Hanabusa, K.: Polymer organogelators that make supramolecular organogels through physical cross-linking and self-assembly. In: Chem. Soc. Rev., 2010, 39, pp. 455–463. DOI: 10.1039 / b910604a reveals that the addition of polymers enables higher mechanical stability of solvogels by forming a polymer backbone.

[0015] Phase change materials (PCMs) can also be used as latent heat storage devices in selected implementations, specifically as solvogels. In PCMs, the liquids stored in the spaces between the solvogels serve as heat or energy storage, but not as a storage medium for applying liquids to surfaces.

[0016] The object of the invention is to provide a method for a Solvogel containing an application material as a polishing, waxing, sealing or varnishing agent, in which the framework structure of the Solvogel is macroscopically stable without the application of force, but becomes microscopically unstable when a surface is brushed over, i.e. a transfer of the physically bound application material contained in the Solvogel to a surface takes place in the area where it is brushed over.

[0017] The problem is solved by features of independent claim 1.

[0018] Solvogele are nanostructured, open-pore solids that can also serve as carrier materials for application substances. They are loaded with the application substance in a one- or two-step process. In contrast to the two-step process, in which the solvent is exchanged with the application substance, the one-step process uses the application substance directly as the solvent during production.

[0019] According to the invention, application materials are to be understood as substances comprising soft waxes, hard waxes, oils, fats, lacquers, dispersion paints, varnishes and resins; in particular, by way of example but not exhaustively, sunflower oil, soybean oil, safflower oil, linseed oil, carnauba and candelilla wax, paraffins, poppy oil, perilla oil, walnut oil, natural waxes, natural resins, shellac, mineral fillers, organic and inorganic pigments, drying agents such as metal siccatives, as well as mixtures of the aforementioned substances with mineral oils.

[0020] Solvogeles can be formed not only from inorganic materials such as titanium dioxide or silicon dioxide as framework structures, but also from organogelators. Classical polymers (PU, PS), cellulose, starch, carbon, or even smaller organic molecules such as low molecular weight organic gelators (LMOGs) can serve as stabilizers for the solvogele framework structures, which are formed, for example, from organogelators.

[0021] Organogelators are molecules that can form three-dimensional networks in a suitable liquid through chemical or physical interactions. These include, for example, hydrogen bonds between the OH or NH groups, π-π interactions, ionic interactions, and van der Waals forces.

[0022] Typical gelator material classes are amino acids, isosorbide derivatives, or amines. Despite their microscale structure, gelator networks are not as structurally robust or retain their liquid application core as other gelators. They lack covalent bonds and readily release the application material from their dendritic structures under the influence of temperature. Nevertheless, despite their inherently lower mechanical stability, they can serve as a framework for solvogele, since the retention capacity of the solvogele for application materials in the invention relates to normal forces such as shear and compressive forces. Temperature influences and changes that could lead to the dissolution of the framework structure and are in the range of more than 100°C are irrelevant in this context, as they are virtually immaterial in the practical application according to the invention.The advantage of using gelators as the sole scaffold structure is the presence of only one scaffold former to generate the scaffold structure, with the absence of polymers in particular eliminating the problem of microplastic residues.

[0023] The following compounds are to be understood as organogelators within the scope of this invention by way of example, but not exhaustively: 1,3:2,4-Dibenzylidene-d-sorbitol (DBS); di-(4-ethylbenzylidene) sorbitol (DpEBS); 1,3:2,4-di-(2,4-dimethylbenzylidene) sorbitol (D2,4-DMBS); 1,3:2,4-di-(2,4dimethylbenzylidene) sorbitol (D2,4-DMBS); 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl)methylene]-nonitol (TBPMN) L-Isoleucine derivatives, L-Valine derivatives, L-Aspartic acid derivatives.

[0024] By combining organogelators with suitable high-molecular-weight polymers, the organogelator frameworks can be stabilized and at least partially replaced. These polymers can be selected from the group of compounds including polyolefins, polyesters, and polyethers, in particular HDPE, UHMWPE, PE1818, and PP. PE1818 is shown in the following structural formula:

[0025] The presence of these aforementioned polymers creates a thin polymer film on the gelator fibers, which can reinforce the network of the framework structure. The composite materials thus produced can, for example, serve as carriers for application materials according to the invention, which can be applied to a surface. The advantage of adding polymers as an additional framework former for the framework structure of the Solvogel is the reduced release of application material and lower temperature sensitivity compared to pure Solvogels, which only have a gelator framework structure, and the more cost-effective production compared to constructing the framework structure solely with a gelator. A Solvogel within the scope of the invention should comprise less than 50% wt., preferably less than 20% wt., and particularly preferably less than 10% wt. polymers as a component of the framework substance.

[0026] If a Solvogel according to the invention, i.e., one with or without polymers, is placed on a rough surface of a body and subsequently moved across the surface, the surface of the framework structure is disrupted due to the at least microscopic irregularities. This allows the application material to emerge from the dendritic structures and be applied to the surface of the body. The movement process can be repeated stepwise or continuously. Through the disruption of the framework structure and the formation of the application material film or layer, the Solvogel is gradually consumed. This means that, in addition to the application material, only the framework structure of the Solvogel remains on the surface. The framework structure typically comprises less than 15% wt., preferably less than 10% wt., and particularly preferably less than 4% wt. of the total weight.According to the invention, consumption is understood to mean a continuous or repeated breaking up of the framework structure, for example on a rough surface, by the action of a normal force on the Solvogel body, in particular in the form of a sliding movement, which leads to a destruction of the framework structure and release of the application material.

[0027] The average surface roughness of the workpieces to be treated is typically in the range of Ra ≥ 0.025. Due to the molecular structure of the framework, even slight forces can cause deformation and thus breakage of the framework.

[0028] In this context, deformation is defined as a change in angle from the lower proximal to the upper distal region of a Solvogel. The displacement of the layers relative to each other creates stresses within the Solvogel, and exceeding this deformation leads to a partial tear or rupture of the framework structure, allowing the applied material to escape from the fractured portion of the Solvogel.

[0029] A deformation of ≥ 1% can occur with a force as low as approximately 0.1 N, causing the solvogel's framework structure to break down. This breakdown can be achieved by applying a normal force to the solvogel body along a surface in the form of a sliding motion. The lateral force acting on the solvogel breaks down a portion of the framework structure, allowing the application material to escape from the spaces between the disrupted dendritic structures. If the sliding motion continues along the surface, the application material can be successively deposited along the sliding path, forming an application film or layer.

[0030] In other words, the abrasive action during gliding or sliding across the rough surface can wear away the outer layer of the Solvogel to such an extent that, with continued gliding or gliding motion, the now exposed new framework structure of the Solvogel comes into contact with the rough surface. While the Solvogel body macroscopically maintains its framework structure without force, in the absence of a normal force (i.e., when no shearing movement occurs), so that its overall form does not collapse without force, the framework structure is, microscopically, gradually abraded, destroyed, and subsequently consumed at the point of contact with the surface. This causes the application material to leak out and form an application film or layer. With continued movement of the Solvogel along the rough surface, the tool according to the invention is successively abrasively consumed.

[0031] The application material contained within the Solvogel body can vary depending on the desired application. For example, oils, resins, or waxes can be used as application materials within the Solvogel. Generally, application materials may be sensitive to oxygen or have a temperature above their melting point within the Solvogel. They may solidify upon initial contact with a rough surface and only after the structural framework has broken down or been consumed, either within or on the at least partially rough surface of the body. For instance, liquid resins may only agglomerate and form a solid coating on the surface after contact of the application material with atmospheric oxygen.It is also conceivable that a relatively viscous application material is applied to a rough surface and only heated after application, causing it to liquefy in order to apply the material into or onto the pores of the surface, for example, to seal a wooden surface. Similarly, the application of a liquid material is conceivable, which does not solidify after application but instead forms, for example, a friction-reducing lubricant layer or a water-repellent grease layer on the surface, such as an oil, liquid wax, or grease film.

[0032] For the practical application and handling of applying the application materials to a surface, application tools for applying or introducing a liquid or solid application material of a Solvogel (a type of applicator) near the surface have been developed according to the invention. The Solvogel is arranged or stored in or on an application tool and comes into contact with the surface of an object through the gradual abrasive wear of the Solvogel's framework structure. In the simplest case, the Solvogel can be held in the bare hand or on a flexible object such as a cloth, rag, or chamois leather and slowly moved over the surface to be applied. Care must be taken to ensure that the released application material is not absorbed or taken up by the fibers of the flexible object.

[0033] To avoid such application errors, a particular embodiment of the invention provides that the Solvogel is held by a handle. The handle can be part of a clamping device that holds the Solvogel. For example, this clamping device could be arranged in or on a trowel or a spatula. However, it is also possible to design the Solvogel so that it can be arranged as a rotationally symmetrical body on polishing machines, eccentric polishers, and orbital sanders. In this case, the Solvogel is attached to a rotating and / or vibrating support body.

[0034] In a particular embodiment, the Solvogel is located within a screw pin, serving as an application tool. This arrangement offers the advantage that the Solvogel does not dry out upon contact with air, no unwanted foreign substances adhere to the Solvogel body, and the consuming framework structure can be fed in a controlled manner. It should be noted that the Solvogel, due to its inherent strength, can simultaneously function as the tool without requiring a covering or support structure.

[0035] The use of Solvogel, which contains an application agent, is intended primarily for use in the trades and DIY sector, especially as a polishing, waxing, oiling or varnishing agent.

[0036] The invention will be explained in detail again using the following examples: In Fig. Figure 1 shows a cross-sectional drawing illustrating the application of an application material 6 to a surface 4 using a rotary tool 2. It can be seen that a Solvogel 1, comprising a framework structure 7 made of dendritic or fibril-like fibers, encloses an application material 6 embedded between the fibers of the framework structure 7. A torsional movement initiated at one end allows the Solvogel 1', transferred into the rotary tool 2, to exit the cylindrical tool 2 at the other end and move along the surface 4 (direction of movement 5). This movement along the surface 4, which has a relative roughness, breaks open the framework structure 7 of the Solvogel 1 or 1', releasing the portion of the application material 6 located within the broken framework structure, which can then be applied to the surface 4.If the movement is continued, a new area of ​​the rough surface 4 is brought into contact with the still undamaged framework structure 7 of the Solvogel 1 or 1' and an application material film or application material layer 3 is created on the surface 4. Synthesis of gelators

[0037] To synthesize di-(4-ethylbenzylidene)sorbite (DpEBS), sorbitol, 4-ethylbenzaldehyde, dodecylbenzenesulfonic acid, N,N-dimethylformamide, and chloroform are mixed in a round-bottom flask and heated under reflux for 2.5 hours. The reaction is carried out under a nitrogen atmosphere. The resulting white solid is neutralized with sodium hydroxide and washed with isopropanol, ethanol, acetone, and hot water, then filtered. After drying in a desiccator, the material is stored in the absence of air.

[0038] Table 1 shows the molar ratios of the chemicals used. Table 1 Gelator: DpEBS mole / mole sorbitol sorbitol 1 4-ethylbenzylaldehyde 2 N,N-dimethylformamide 0,45 Dodecylbenzenesulfonic acid 0,25 chloroform 7

[0039] To synthesize di-(2,4-dimethylbenzylidene)sorbitol (D2,4-DMBS), sorbitol, 2,4-dimethylbenzaldehyde, cyclohexane, toluenesulfonic acid, anisole, and ethanol are heated under reflux in a round-bottom flask under a nitrogen atmosphere for 2.5 hours. The white product is neutralized with sodium hydroxide and washed with ethanol, acetone, and hot water. After drying the product in a desiccator, the material is ground into a powder using a spatula. The synthesis of di-(3,4-dimethylbenzylidene)sorbitol follows the same procedure, with the sole difference being that 3,4-dimethylbenzaldehyde is used instead of 2,4-dimethylbenzaldehyde.

[0040] The molar ratios of the components are given in Table 2. Table 2 Gelator Gelator D2,4-DMBS D2,4-DMBS mole / mole Sorbitol Sorbitol 1 1 2,4-Dimethylbenzaldehyde 2,3 3,4-Dimethylbenzaldehyde 2,1 Cyclohexane 6,5 4 Toluenesulfonic acid 0,02 0,02 Anisole 2 2 Ethanol 10 12 Di-(3,4-dimethylbenzylidene) sorbitol

[0041] The application material is a natural or mineral oil containing one of the exemplary isosorbide derivatives mentioned, in particular di-(4-ethylbenzylidene) sorbitol (DpEBS); 1,3:2,4-di-(2,4-dimethylbenzylidene) sorbitol (D2,4-DMBS); 1,3:2,4-di-(2,4-dimethylbenzylidene) sorbitol (D2,4-DMBS); The compounds are heated until a homogeneous solution is formed and then converted into a sol bird by controlled cooling. Mass fractions of 0.5–20%, preferably 2–10%, and particularly preferably 4–8% of the isosorbide derivatives are used as the gelator. Ideally, the sol bird solidifies into a shape that is advantageous for later use. Solvogel production Example 1

[0042] To produce the Solvogel, the application material linseed oil and the gelator 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl)methylene]-nonitol (TBPMN) are mixed in a mass ratio of 99:1, heated until a homogeneous solution is obtained, and then converted into a Solvogel by controlled cooling. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements using a plate-plate setup show that the gel structure degrades under a normal force of 0.1 N and with a deformation of ≥1%. Example 2

[0043] To produce the Solvogel, the application material linseed oil and the gelator 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl)methylene]-nonitol (TBPMN) are mixed in a mass ratio of 85:15, heated until a homogeneous solution is obtained, and then cooled in a controlled manner to form a Solvogel. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements using a plate-plate setup show that the gel structure degrades at both a normal force of 0.1 N and a deformation of ≥1%, and at a normal force of 15 N and a deformation of ≥1%. This demonstrates that the movement of the tool on a surface is particularly relevant for material application, rather than the pressure with which the Solvogel is pressed against the surface. In this case, the normal force is merely a measurement requirement to ensure complete contact between the sample and the measuring head.This is a key distinguishing feature that differentiates the tool according to the invention from conventional cloths, sponges and brushes, where the material discharge is strongly dependent on pressure. Example 3

[0044] To produce the Solvogel, the application material (hard wax) is mixed with mineral oil (C9-C12) and the gelator (1,3:2,4-dibenzylidene-d-sorbitol (DBS)) in a mass ratio of 97:3. The mixture is heated until a homogeneous solution is obtained and then cooled in a controlled manner to form a Solvogel. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements using a plate-plate setup show that the gel structure degrades under a normal force of 1 N and deformation of ≥1.1%. Example 4

The mixture is heated until a homogeneous solution is obtained and then cooled in a controlled manner to form a Solvogel. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements using a plate-plate setup show that the gel structure degrades under a normal force of 0.1 N and deformations of ≥3.7%. Example 5

The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements at 50 °C using a plate-plate setup show degradation of the gel structure under a normal force of 3 N and a deformation of ≥3.7%. Example 6

[0047] To produce the Solvogel, the application material paraffin wax, the polymer polypropylene, and the gelator 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl)methylene]-nonitol (TBPMN) are mixed in a mass ratio of 96:2:2, heated until a homogeneous solution is obtained, and then converted into a Solvogel by controlled cooling. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements at 50 °C using a plate-plate setup show degradation of the gel structure under a normal force of 3 N and a deformation of ≥1.6%. Example 7

[0048] To produce a Solvogel, the application material (paraffin wax), the polymer polyester, and the gelator 1,2,3-trideoxy-4,6:5,7-bis-O-[(4-propylphenyl)methylene]-nonitol (TBPMN) are mixed in a mass ratio of 96:2:2, heated until a homogeneous solution is obtained, and then cooled in a controlled manner to form a Solvogel. The resulting gel is suitable for applying the application material to various surfaces. Rheological measurements at 50 °C using a plate-plate setup show that the gel structure degrades under a normal force of 3 N and with a deformation of ≥1.5%. Application of materials to workpieces can be achieved either to achieve near-surface penetration or to leave a film or particle trail on the surface.
