Description

[Technical Field]

[0001] We claim priority from European Patent Application No. 23 178 839.9, filed on 13 June 2023.

[0002] The present invention relates to a fast-curing two-component system based on a moisture-curing prepolymer, preferably a silyl-modified prepolymer (SMP). When the first component is mixed with the second component, the resulting mixture cures in a relatively short time. The curing two-component system is useful as an adhesive or sealant and can be used with standard equipment for applying two-component systems. [Background technology]

[0003] Adhesives and encapsulants based on silyl-modified prepolymers are known as typical pretreatment-free solutions. Due to tightening regulatory restrictions, silane-terminated prepolymer chemistry is focusing on environmentally friendly solutions. Adhesives and sealants based on silyl-modified prepolymers include, for example, EP 3 546 541 A1, CN 109 880 570 A, US 6 762 242 B1, US 2007 0237912 A1, US 2007 0088110 A1, US 2010 0197855 A1, US 2011 0232825 A1, US 2011 0308730 A1, US 2012 0225983 A1, US 2012 0055105 A1, US 2014 0228515 A1, WO 2014 073593 A1, WO 2015 / 185642 A1, WO 2017 142714 A1, WO It is publicly known from 2017 189057 A1, US 2018 0134932 A1, WO 2018 074925 A1, US 2019 0048190 A1, US 2019 0144717 A1, US 2019 0233335 A1 and WO 2022 122782 A1.

[0004] Adhesives and sealants based on silyl-modified prepolymers are typically one-component adhesives. These one-component systems are typically slow-reacting products controlled by water diffusion. They are not moisture-containing themselves but absorb water from the environment, such as from the air. Consequently, curing times are relatively long, for example, 12 to 24 hours.

[0005] Rapid curing can be achieved by providing adhesives and sealants based on silyl-modified prepolymers in the form of a two-component system, where one component is water-free and contains the silyl-modified prepolymer, and the other component is an accelerator paste (booster system) typically containing water to eliminate dependence on moisture in the environment for slow curing. However, accelerator pastes (booster systems) generally have a relatively small volume, which needs to be mixed with the other component containing the silyl-modified prepolymer, which has a relatively large volume, before application. As a result, such rapid-curing two-component systems typically require a mixing ratio of the two components to each other of 40:1 to 100:1.

[0006] However, such two-component systems have several drawbacks due to their high mixing ratios. To cope with the large volume difference between the main component and the accelerator paste, the dispensing must be very specific and precise. Such two-component systems cannot be applied using commonly used, standard dispensing devices customized for 1:1 or 2:1 mixing ratios. Only commercially available specialized dispensing and mixing equipment is usable, but this is not widely accepted due to its very high cost and limitations in terms of multi-sourcing from different adhesive system suppliers.

[0007] When such a two-component system is formulated to allow for lower mixing ratios, for example, 1:1 or 2:1, the volume of the accelerator paste (booster system) is increased by adding a plasticizer or binder, which impairs the mechanical properties of the cured sealant or adhesive.

[0008] WO 2020 067877 A1 relates to a composition for use as a sealant or adhesive, particularly to a silyl-terminated polymer used in combination with a specific booster containing additives.

[0009] Furthermore, adhesive or encapsulant compositions must satisfy not only specific performance characteristics such as high strength combined with high elongation, but also durable adhesion under various climatic conditions. Climate cycle tests, including sample testing under harsh conditions such as 70°C cataplasm with a freezing step, have been developed by original equipment manufacturers (OEMs). Modern adhesive or encapsulant compositions must pass such tests.

[0010] Conventional adhesive or sealant compositions are often based on polyurethanes containing reactive isocyanate groups such as toluene diisocyanate (TDI), methylene bisphenyl diisocyanate (MDI), hexamethylene diisocyanate (HDI), naphthalene diisocyanate (NDI), and diisocyanate dicyclohexyl urethane. Such isocyanate products are dangerous because they are highly irritating to the mucous membranes of the eyes, gastrointestinal tract, and respiratory tract. Health effects of exposure to isocyanates include skin and mucous membrane irritation, chest tightness, and difficulty breathing. Isocyanates include compounds that are classified as potential human carcinogens and are known to cause cancer in animals. The main effects of dangerous exposure are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin.

[0011] Furthermore, conventional adhesive or encapsulant compositions often contain phthalates as plasticizers. While phthalate plasticizers are not chemically bonded in the cured adhesive composition, they can leach, migrate, or evaporate into the indoor air. Building materials such as vinyl flooring and other consumer products containing phthalates can lead to indirect human exposure through direct contact and use, leaching into other products, or general environmental contamination. Humans are exposed throughout their lives through ingestion, inhalation, and dermal exposure. Many phthalates are endocrine disruptors that interfere with testosterone production. Prenatal exposure to certain phthalates causes common adverse effects on the reproductive development of male animals, resulting in what is known as "phthalate syndrome," which bears many similarities to human "testicular dysplasia."

[0012] Therefore, there is a demand for adhesive or encapsulant compositions that do not contain isocyanates or phthalates. While certain adhesive compositions based on silicone polymers, such as polysiloxanes, are well-known encapsulants, durable elastic adhesive compositions that achieve comparable performance, such as those based on polyurethane prepolymers, have not been available for decades.

[0013] Furthermore, conventional adhesive or encapsulant compositions often require pretreatment of the substrate surface before application to provide satisfactory bonding. However, such pretreatment is time-consuming and laborious, and there is a demand for adhesive or encapsulant compositions that do not require such pretreatment and yet still provide excellent adhesion to the surfaces of various materials, including glass, plastics, and metals.

[0014] Furthermore, adhesive bonds or seals that need repair after a certain period of use, or, for example, after an accident, are replaced. However, conventional adhesive or sealant compositions, especially when bonded to a polyurethane substrate, are often difficult to remove or repair. Therefore, it is desirable to provide an adhesive or sealant composition that facilitates replacement and repair. [Overview of the Initiative] [Problems that the invention aims to solve]

[0015] The object of the present invention is to overcome the drawbacks of the prior art and provide an adhesive or encapsulant composition that satisfies one or more of the above-mentioned needs. [Means for solving the problem]

[0016] This objective was achieved by the subject matter of the claims.

[0017] It has been remarkably found that a rapidly curing two-component system can be provided at a mixing ratio of approximately 1:1 or 2:1 (v / v) without the need to include significant amounts of fillers, binders, plasticizers, or other inert components in the accelerator paste (booster) so as not to impair the mechanical properties of the cured composition (adhesive and / or sealant).

[0018] In particular, and surprisingly, it was found that the silyl-modified prepolymer can be stabilized without premature curing even in the presence of water. According to the prior art, on the one hand, a water-curable prepolymer (e.g., a silyl-modified prepolymer), and on the other hand, an accelerator (e.g., water), must be strictly separated from each other during storage to prevent premature viscosity increase and curing. In contrast, the present invention provides a storage-stable two-component system in which the water-curable prepolymer (e.g., a silyl-modified prepolymer) comes into direct contact with water during storage.

[0019] As a result, the total amount of water-curable prepolymer (e.g., silyl-modified prepolymer) can be distributed across the first and second components of the curable two-component system. Thus, the volumes of the first and second components can be adjusted to a ratio of approximately 1:1 or 2:1 (v / v), for example, without the need to add large amounts of fillers, binders, plasticizers, or other inert components. Once the two components are mixed together, the entire mixture begins to cure.

[0020] Without being constrained by scientific theory, it appears that water-curable prepolymers, particularly silyl-modified prepolymers, can be stabilized in the presence of water with certain additives at an elevated pH. When a first component containing such a stabilized silyl-modified prepolymer in the presence of water at an elevated pH is mixed with a second component preferably containing a curing catalyst, the pH of the resulting mixture decreases, thereby weakening the stabilization of the silyl-modified prepolymer and consequently inducing rapid curing. Curing is preferably accelerated by the presence of the curing catalyst in the second component, but is not necessarily required. In certain embodiments, the change in pH alone may be sufficient to induce rapid curing, even in the absence of a curing catalyst. If the resulting pH is very low or very high, the curing mechanism is acid-catalyzed or base-catalyzed, and therefore a curing catalyst may not be required. If the resulting pH is closer to neutral, a curing catalyst is generally required to achieve rapid curing. Whether or not a catalyst is required depends on the pH obtained after mixing and the pH before mixing. Furthermore, if present, the amount of curing catalyst also appears to play a role in overcoming the stabilizing effect so that rapid curing is induced.

[0021] During storage, i.e., before mixing with a second component preferably containing a curing catalyst (typically water-free), the mixture of silyl-modified prepolymer and water can be stabilized by an elevated pH value. Additives that contribute to stabilization (i.e., avoiding premature curing) include Na + Aeon, K + Examples include ions, metal hydroxides (such as Al(OH)3), metal oxides (such as Al2O3, MgO, and ZnO), SiO2, natural or synthetic minerals having or forming Si-OH groups upon contact with water (including minerals containing Al2O3, MgO, ZnO, and SiO2), carbon black, graphene, graphene oxide, organically modified graphene, nitrides (such as AlN and BN), and graphite.

[0022] All of these additives appear to interact with the silanol groups of the silyl-modified prepolymers, at least partially hydrolyzed, and can stabilize them, for example, through electrostatic repulsion under pH-specific conditions influenced by the respective electrostatic properties of the functionalized silane and silyl-modified prepolymers.

[0023] Silicates, particularly certain fillers such as talc, MgO, ZnO, Al2O3, and graphene oxide, appear to interact with silanol groups and be able to complexate them. Also, Na + Aeon, K + Ions and other elements stabilize silyl-modified prepolymers in the presence of water. Metal ions and metal oxides appear to form stable silanol complexes, which suppress the condensation of active silanol species in a basic environment.

[0024] The amount of ions required to provide sufficient stabilization varies depending on the pH value. It appears that the higher the pH value, the less ions are needed for stabilization.

[0025] Surprisingly, the pH value and Na + The content of the ion donor (Na donor) has been found to be related to the stability of the binary system, particularly the stabilization of the moisture-curing prepolymer, preferably the silyl-modified prepolymer, in the presence of water. A pH value of 5 to 10, preferably 7 to 10, has been found to stabilize the binary system. Furthermore, at least about 0.03 wt.%, preferably at least about 0.04 wt.%, of Na is found to be present. + It has been found that the content of an ion donor (Na donor), preferably Na2O, NaOH, or a mixture thereof, can stabilize the binary system. A pH value of 5 to 10, preferably 7 to 10, and at least about 0.03 wt.%, preferably at least about 0.04 wt.%, of Na + The combination of an ion donor (Na donor), preferably Na2O, NaOH, or a mixture thereof, is particularly useful for stabilizing the binary system.

[0026] pH value, Na + ions and / or K + Surprisingly, it has been found that various properties of a two-component system can be manipulated by the combination of the presence and amount of pH value, Na ions and / or K ions, the presence and amount of metal oxides capable of forming stable silanol complexes, the presence and amount of metal catalysts, and the presence and amount of amine catalysts. The manipulable properties include, but are not limited to, cure kinetics, latency, open time, strength gain, and storage life.

[0027] In the present invention, the mixing ratio can be reduced to 1:1 (v / v) without impairing the mechanical properties. Water as a curing agent and a silyl-terminated prepolymer of any backbone chemistry can be combined with suitable storage stability and without dilution by fillers, binders, plasticizers or other inert substances that would otherwise compromise the mechanical properties. Further, the pair of components (the first component) comprising the stabilized silyl-modified prepolymer and water can be combined with different silyl-modified prepolymer components (the second component) to easily vary the material properties of the resulting mixture.

[0028] In the present invention, a moisture-curable prepolymer and water can be combined in a very stable manner. This stabilized formulation (the first component) preferably does not increase in viscosity or cure until it is mixed with the other component (the second component) of a two-component system that includes a curing catalyst. Only upon mixing (e.g., statically or dynamically), a change in pH value and / or the curing catalyst of the other component (the second component) induces curing to form bonds and / or seals.

[0029] Moisture stabilization also simplifies the manufacturing process of the two-component system according to the present invention because laborious steps such as drying of fillers and other components can be omitted. It is not necessary to minimize or completely remove the presence of water.

It includes or is essentially derived from it.

[0032] For the purposes of this specification, unless otherwise expressly stated, percentages are weight percentages and ppm refers to weight. Unless otherwise expressly stated, standards such as EN ISO and ASTM are in their official versions as of January 1, 2023.

[0033] The expression "essentially derived from" means that the content is at least about 95 wt.%, preferably at least about 99 wt.%, relative to the total weight of the component referred to in the definition.

[0034] The system according to the present invention is a two-component system comprising a first component and a second component. The first component is spatially separated from the second component and is located, for example, in separate cartridges or other suitable containers. Preferably, the two-component system consists essentially of the first component and the second component. However, in addition to the first and second components, the two-component system according to the present invention may include one or more additional components, in which case it is intended to be considered a multi-component system.

[0035] The two-component system according to the present invention is preferably a ready-to-use composition that already contains all the materials necessary for the desired purpose. In particular, the curable two-component system according to the present invention preferably does not require the addition of further additives before use. The curable two-component system only requires mixing the first and second components together under ambient conditions, for example, at room temperature (23°C).

[0036] The two-component system according to the present invention is curable, meaning that after mixing the first and second components, it can autonomously undergo a curing reaction, typically by crosslinking.

[0037] The composition is particularly useful for bonding and joining similar and dissimilar substrates.

[0038] For the purposes of this specification, a “prepolymer” (polymer precursor) is a monomer or system of monomers that has reacted to an intermediate molecular weight state. This substance can be further polymerized to a high molecular weight state that is fully cured by reactive groups. A prepolymer encompasses a mixture of a reactive polymer and unreacted monomers. A prepolymer is moisture-curable, meaning that it undergoes spontaneous curing upon contact with moisture, along with other materials optionally included in the composition, such as a curing agent.

[0039] In a preferred embodiment of the curable two-component system according to the present invention, one or more moisture-curable prepolymers comprise or are essentially comprised of one or more silyl-modified prepolymers.

[0040] The curable two-component system according to the present invention may contain a single moisture-curable prepolymer or a mixture of two or more moisture-curable prepolymers in both components. When two or more moisture-curable prepolymers are present, all weights and percentages refer to the total weight of all moisture-curable prepolymers included in the curable two-component system.

[0041] Preferably, the silyl-modified prepolymer comprises a polymer backbone and one or more hydrolyzable silyl groups.

[0042] It is intended that at least a portion of the hydrolyzable silyl group may exist in a hydrolyzed form. For example, if the hydrolyzable silyl group is a methoxysilyl group, it may be hydrolyzed at least partially to methanol and a silanol group (R3Si-OCH3+H2O→R3Si-OH+HOCH3).

[0043] The silyl-modified or functionalized prepolymer may be a combination of silyl-modified polyethers or other types of monomers to form the prepolymer formulation. This includes PU-type prepolymers silane-terminated with any type of functionalized silane.

[0044] This silyl-modified prepolymer can be used as an all-component in adhesive systems with two or more components. Both components may also include fillers such as calcium carbonate, clay, bentonite, metal oxides and their hydroxides such as aluminum trihydrate, carbon black, layered silicates, and other natural or synthetic minerals.

[0045] Examples of silyl-modified polymers include, but are not limited to, silyl-modified polyethers and copolyethers, silyl-modified polyisobutylene (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0046] Preferably, the silyl-modified prepolymer has a non-silicone backbone, more preferably a polyether backbone. For example, the silyl-modified prepolymer may be a dimethoxysilyl-modified polymer, a trimethoxysilyl-modified polymer, or a triethoxysilyl-modified polymer. For example, the silyl-modified prepolymer may be a silyl-modified polyether or a copolyether.

[0047] In this embodiment, the silyl-modified prepolymer may contain heteroatoms such as N, O, S, or other functional group urethanes between monomer units to provide different properties targeted for different applications and functions.

[0048] For the purposes of this specification, a prepolymer (polymer precursor) is a monomer or system of monomers that has reacted to an intermediate molecular weight state. This substance can be further polymerized to a high molecular weight state that is fully cured by reactive groups. The prepolymer comprises a mixture of reactive polymer and unreacted monomer. The prepolymer is moisture-curable, meaning that it undergoes spontaneous curing upon contact with moisture, along with other materials optionally included in the composition, such as a curing agent.

[0049] Moisture-curing prepolymers are known to those skilled in the art and are commercially available.

[0050] In a preferred embodiment of the curable two-component system according to the present invention, the moisture-curable prepolymer is a silyl-modified prepolymer. Since the preferred silyl-modified polymer is a curable prepolymer, it is a reactive prepolymer (reactive silyl-modified prepolymer). Silyl-modified prepolymers (SMPs, silane-modified polymers, modified silane polymers, MS polymers, silane-terminated polymers, etc.) are known to those skilled in the art and are commercially available. For details on silyl-modified prepolymers, see, for example, SM Guillaume, Advances in the synthesis of silyl-modified polymers (SMPs), Polym. Chem., 2018, 9, 1911-1926; A. Pizzi et al., Handbook of Adhesive Technology, CRC Press, 3rd edition, 2018. Examples of silyl-modified polymers include, but are not limited to, silyl-modified polyethers and copolyethers, silyl-modified polyisobutylene (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0051] Preferably, the silyl-modified prepolymer has a non-silicone backbone, and more preferably, the silyl-modified prepolymer has a polyether backbone. For example, the silyl-modified prepolymer may be a dimethoxysilyl-modified polymer, a trimethoxysilyl-modified polymer, or a triethoxysilyl-modified polymer. For example, the silyl-modified prepolymer may be a silyl-modified polyether or a copolyether.

[0052] A preferred silyl-modified prepolymer according to the present invention is - Silyl-modified polyethers or copolyethers, preferably silyl-terminated polyethers or copolyethers, such as silyl-modified polyethylene glycol, silyl-modified polypropylene glycol, etc. - Silyl-modified polyurethanes, preferably silyl-terminated polyurethanes, and - Silyl-modified acrylates, preferably silyl-terminal acrylates Selected from.
