Description

[0001] Priority is claimed to European patent application no. 23 178 839.9, filed on June 13, 2023.

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

[0003] Adhesives and sealants based on silane-modified prepolymers are known to be typically pretreated solutions. Due to increased regulatory restrictions, silane-terminated prepolymer chemistry is focusing on environmentally friendly solutions. From e.g. EP 3 546 541 A1, CN109 880 570 A, US 6 762 242 B1, US 2007 0237912 A1, US 2007 0088110 A1, US 20100197855 A1, US 2011 0232825 A1, US 2011 0308730 A1, US 2012 0225983 A1, US 20120055105 A1, US 2014 0228515 A1, WO 2014 073593 A1, WO 2015 / 185642 A1, WO 2017142714 A1, WO 2017 189057 A1, US Adhesives and sealants based on silyl-modified prepolymers are known from 2018 0134932 A1, WO 2018 074925 A1, US 20190048190 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 generally slow-reaction products with water diffusion control. They do not contain moisture themselves, but absorb moisture from the environment, such as atmospheric moisture. The curing time is therefore 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 two-component systems. One component of the two-component system is anhydrous and contains the silyl-modified prepolymer, while the other component is an accelerator paste (co-accelerator system) that typically contains water to eliminate slow dependence on ambient moisture. However, the accelerator paste (co-accelerator system) usually has a relatively small volume and needs to be mixed with the other components, which contain a relatively large volume of silyl-modified prepolymer, before application. Therefore, such rapid-curing two-component systems typically require a mixing ratio between the two components of 40:1 to 100:1.

[0006] However, this two-component system has several drawbacks due to its high mixing ratio. Dosing needs to be very specific and accurate to handle the large volumetric dosage differences between the main component and the accelerator paste. This two-component system cannot be applied using commonly available standard dosing equipment tailored for 1:1 or 2:1 mixing ratios. Only specialized dispensing and mixing tools available on the label can be used, but these are not widely acceptable due to their very high cost and the limitation imposed by the diverse sources of different binder system suppliers.

[0007] When such a two-component system is formulated at a lower mixing ratio that allows, for example, 1:1 or 2:1, the volume of the accelerator paste (co-accelerator system) is increased by adding plasticizers or binders; however, this impairs the mechanical properties of the cured sealant or adhesive.

[0008] WO 2020 067877 A1 relates to silyl-modified end-capped polymers used in compositions as sealants or adhesives, and particularly in combination with specific accelerators containing additives.

[0009] Furthermore, adhesive or sealant compositions need to meet specific performance properties, such as high strength paired with high elongation and durable adhesion under various climatic conditions. Original equipment manufacturers (OEMs) have developed climate cycling tests, which involve testing samples under harsh conditions, such as 70°C cataplasm with a freezing step. Modern adhesive or sealant compositions are required to pass this test.

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

[0011] In addition, conventional adhesive or sealant compositions often contain phthalates as plasticizers. Phthalate plasticizers are not chemically bonded in the cured adhesive composition but can leach, migrate, or evaporate into indoor air. Building materials such as vinyl flooring and other consumer products containing phthalates can lead to human exposure through direct contact and use, indirectly through leaching into other products, or general environmental contamination. Humans are exposed throughout their lifespan through ingestion, inhalation, and skin exposure. Many phthalates are hormone-disrupting chemicals that interfere with testosterone production. Prenatal exposure to certain phthalates has common adverse effects on male reproductive development in animals, resulting in so-called "phthalate syndrome," which shares many similarities with "testicular hypoplasia syndrome" in humans.

[0012] Therefore, there is a need for adhesive or sealant compositions that do not contain either isocyanates or phthalates. While certain adhesive compositions based on silicone polymers such as polysiloxanes are also well-known sealants, durable, resilient adhesive compositions that achieve the same performance as those based on polyurethane prepolymers have not been available for decades.

[0013] Furthermore, conventional adhesive or sealant compositions typically require pretreatment of the substrate surface to provide satisfactory adhesion before the composition is applied. However, this pretreatment is time-consuming and labor-intensive, and there is a demand for adhesive or sealant compositions that do not require such pretreatment but still provide excellent adhesion to a wide range of materials, including glass, plastics, and metals.

[0014] Furthermore, after a period of use or, for example, after an accident, it is necessary to replace or repair adhesive bonds or sealants. However, conventional adhesive or sealant compositions are often difficult to remove or repair, especially when they are bonded to polyurethane substrates. Therefore, it is desirable to provide adhesive or sealant compositions that facilitate replacement and repair.

[0015] The object of the present invention is to provide an adhesive or sealant composition that overcomes the disadvantages of the prior art and meets one or more of the above-mentioned needs.

[0016] This objective has been achieved through the subject matter of the patent claims.

[0017] Surprisingly, it was found that fast-curing two-component systems can be provided at mixing ratios of approximately 1:1 or 2:1 (v / v) without requiring significant amounts of fillers, binders, plasticizers, or other inert components in the accelerator paste (co-accelerator) so as not to impair the mechanical properties of the cured composition (adhesive and / or sealant).

[0018] In particular, it was surprisingly found that silyl-modified prepolymers remain stable even in the presence of water without premature curing. According to existing technology, the wet-curable prepolymer (e.g., silyl-modified prepolymer) and the accelerator (e.g., water) must be strictly separated during storage to prevent premature viscosity increase and curing. In contrast, the present invention provides a storage-stable two-component system in which the wet-curable prepolymer (e.g., silyl-modified prepolymer) is in direct contact with water during storage.

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

[0020] Without being bound by any scientific theory, it appears that wettable curable prepolymers, particularly silyl-modified prepolymers, can be stabilized in the presence of water at elevated pH values ​​with specific additives. When a first component containing such a stabilized silyl-modified prepolymer is mixed with a second component, preferably containing a curing catalyst, in the presence of water at an elevated pH value, the resulting mixture has a lower pH value, thereby weakening the stability of the silyl-modified prepolymer and inducing rapid curing. Curing is preferably, but not necessarily, promoted by the presence of a curing catalyst in the second component. In certain embodiments, even in the absence of a curing catalyst, a change in pH alone is sufficient to induce rapid curing. If the resulting pH value is quite low or quite high, the curing mechanism is acid-catalyzed or base-catalyzed, making a curing catalyst potentially unnecessary. If the resulting pH value is closer to neutral, a curing catalyst is generally required to achieve rapid curing. The need for or lack thereof depends on the pH obtained after mixing and the pH before mixing. Furthermore, it appears that the amount of curing catalyst (if present) can also play a role in overcoming stabilizing effects, thereby inducing rapid curing.

[0021] During storage, i.e., before mixing with a second component that preferably contains a curing catalyst (and is typically anhydrous), the mixture of silyl-modified prepolymer and water can be stabilized by increasing the pH value. Additives that help stabilize (i.e., prevent premature curing) include Na. ＋ Ions, K ＋ Ions, metal hydroxides (e.g., Al(OH)3), metal oxides (e.g., Al2O3, MgO, and ZnO), SiO2, natural or synthetic minerals having or forming Si-OH groups upon contact with water (including those containing Al2O3, MgO, ZnO, and SiO2), carbon black, graphene, graphene oxide, organically modified graphene, nitrides (e.g., AlN and BN), and graphite.

[0022] It appears that all these additives can interact with the silanol groups of at least partially hydrolyzed silyl-modified prepolymers, and, for example, under pH-specific conditions, stabilize them by electrostatic repulsion, influenced by the respective electrostatic properties of the functionalized silanes and silyl-modified prepolymers.

[0023] It appears that certain fillers, such as silicates, particularly talc, MgO, ZnO, Al2O3, and graphene oxide, can interact with and complex silanol groups. Furthermore, Na... ＋ Ions, K ＋ Ions stabilize silane-modified prepolymers in the presence of water. It appears that metal ions and metal oxides form stable silanol complexes and inhibit the condensation of reactive silanols in alkaline environments.

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

[0025] Surprisingly, it was found that pH and Na ＋ The content of the ion donor (Na donor) is related to the stability of the two-component system in the presence of water, particularly the stability of wettable curable prepolymers, preferably silyl-modified prepolymers. It has been found that a pH of 5 to 10, preferably 7 to 10, can stabilize the two-component system. Furthermore, Na has been found to... ＋ The ion donor (Na donor), preferably Na₂O, NaOH, or a mixture thereof, has a content of at least about 0.03 wt.-%, preferably at least about 0.04 wt.-%, which can stabilize the two-component system. The pH value is 5 to 10, preferably 7 to 10, and Na... ＋ An ion donor (Na donor), preferably Na₂O, NaOH or a mixture thereof, is present in an amount of at least about 0.03 wt.-%, preferably at least about 0.04 wt.-%, which is particularly useful for stabilizing the binary system.

[0026] Surprisingly, it was discovered that pH and Na+ could be affected. ＋ Ions and / or K ＋ The presence and amount of 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 can be combined to manipulate various properties of a two-component system. Manipulated properties include, but are not limited to, curing kinetics, latency, open time, strength growth, and storage life.

[0027] This invention allows mixing ratios reduced to 1:1 (v / v) without compromising mechanical properties. Suitable combinations of water as a curing agent and any main-chain chemistry of silyl-terminated prepolymers can be achieved without any dilution with fillers, binders, plasticizers, or other inert materials that would otherwise impair mechanical properties. Furthermore, the paired component (first component) comprising a stable silyl-modified prepolymer and water can be combined with different silyl-modified prepolymer components (second component) to readily modify the material properties of the resulting mixture.

[0028] This invention allows for the combination of wettable curable prepolymers and water in a very stable manner. This stable formulation (first component) does not acquire viscosity or cure until it is mixed with other components (second component) of the two-component system, preferably containing a curing catalyst. Only upon mixing (e.g., static or dynamic), changes in pH and / or the curing catalyst of the other component (second component) trigger curing to form an adhesive and / or seal.

[0029] Moisture stability also benefits the manufacturing process of the two-component system according to the invention, as laborious steps such as drying the filler and other components can be omitted. It is not necessary to minimize or completely eliminate the presence of water.

[0030] A first aspect of the invention relates to a curable two-component system, preferably an adhesive and / or sealant, comprising or substantially consisting of the following:

[0031] (a) The first component, which comprises:

[0032] - One or more moisture-curable prepolymers;

[0033] - Optional, water; and

[0034] One or more of the following:

[0035] - One or more alkaline inorganic fillers or their dehydrated products;

[0036] - Graphene component;

[0037] - Natural or synthetic silicates;

[0038] - Carbon black;

[0039] - Expandable graphite;

[0040] The first component does not contain a curing catalyst; and

[0041] (b) A second component, which optionally but preferably comprises one or more curing catalysts;

[0042] Preferably, the first component comprises

[0043] - One or more moisture-curable prepolymers;

[0044] - One or more alkaline inorganic fillers or their dehydrated form; and

[0045] - Optionally, but preferably, water.

[0046] Preferably, the curable two-component system according to the present invention comprises or is substantially composed of the following:

[0047] (a) The first component, which comprises:

[0048] - One or more moisture-curable prepolymers;

[0049] - One or more alkaline inorganic fillers or their dehydrated products;

[0050] - Optional: land, water;

[0051] The first component does not contain a curing catalyst; and

[0052] (b) A second component, which optionally but preferably contains one or more curing catalysts.

[0053] For the purposes of this specification, percentages are weight percentages unless otherwise expressly stated, and ppm are weight-related. Unless otherwise expressly stated, any standards such as EN, ISO, and ASTM are the official versions effective January 1, 2023.

[0054] The phrase “consisting essentially of” means a content of at least about 95 wt.-% and preferably at least about 99 wt.-% relative to the total weight of the component referred to in the definition.

[0055] The system according to the invention is a two-component system comprising a first component and a second component. The first component and the second component are spatially separated, for example, in a separate box or other suitable container. Preferably, the two-component system consists essentially of the first component and the second component. However, it is contemplated that, in addition to the first and second components, the two-component system according to the invention may contain one or more additional components, and thus can be considered a multi-component system.

[0056] The two-component system according to the invention is preferably a ready-to-use composition that already contains all the ingredients required for the desired purpose. In particular, the curable two-component system according to the invention preferably does not require any further additives before use; it only requires mixing the first and second components with each other under ambient conditions, such as at room temperature (23°C).

[0057] The two-component system according to the invention is curable, that is, it can typically undergo a curing reaction autonomously after the first and second components are mixed together via crosslinking.

[0058] The composition is particularly useful for bonding and joining similar and dissimilar substrates.

[0059] For the purposes of this specification, a "prepolymer" (polymer precursor) is a monomer or monomer system that has already reacted to an intermediate molecular weight state. This material is capable of further polymerization via reactive groups to a fully cured high molecular weight state. The prepolymer comprises a mixture of reactive polymers and unreacted monomers. The prepolymer is moisture-curable, meaning it undergoes spontaneous curing upon contact with moisture, and optionally also includes other components contained in the composition, such as a curing agent.

[0060] In a preferred embodiment of the curable two-component system according to the present invention, one or more wet-curable prepolymers comprise one or more silyl-modified prepolymers, or are substantially composed of one or more silyl-modified prepolymers.

[0061] 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 the two components. In the presence of two or more moisture-curable prepolymers, all weights and percentages refer to the total weight of all moisture-curable prepolymers contained in the curable two-component system.

[0062] Preferably, the silyl-modified prepolymer comprises a polymer backbone and one or more hydrolyzable silyl groups.

[0063] It is anticipated that at least a portion of the hydrolyzable silane can exist in a hydrolyzable form. Thus, for example, when the hydrolyzable silane is a methoxysilane, it can be at least partially hydrolyzed to methanol and silanol (R3Si-OCH3+H2O->R3Si-OH+HOCH3).

[0064] Silyl-modified or functionalized prepolymers can be combinations of silyl-modified polyethers or other types of monomers to form prepolymer formulations. This includes typical PU prepolymers with silanes terminalized with any type of functionalized silane.

[0065] This silyl-modified prepolymer can be used in all components of two-component or multi-component adhesive systems. The two components can also contain fillers such as calcium carbonate, kaolin, bentonite, metal oxides and their hydroxides such as aluminum trihydrate, carbon black, layered silicates and other natural or synthetic minerals.

[0066] Examples of silyl-modified polymers include, but are not limited to, silyl-modified polyethers and coethers, silyl-modified polyisobutylene (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0067] Preferably, the silyl-modified prepolymer has a non-organosilicon backbone, more preferably a polyether backbone. For example, the silyl-modified prepolymer can be a dimethoxysilyl-modified polymer, a trimethoxysilyl-modified polymer, or a triethoxysilyl-modified polymer. For example, the silyl-modified prepolymer can be a silyl-modified polyether or a copolyether.

[0068] In this embodiment, the silyl-modified prepolymer may contain heteroatoms such as N, O, S or other functional groups (urethane esters) between monomer units to provide different properties for different applications and functions.

[0069] For the purposes of this specification, a prepolymer (polymer precursor) is a monomer or monomer system that has already reacted to an intermediate molecular weight state. This material is capable of further polymerization via reactive groups to a fully cured high molecular weight state. The prepolymer comprises a mixture of reactive polymers and unreacted monomers. The prepolymer is moisture-curable, meaning it undergoes spontaneous curing upon contact with moisture, and optionally also involves other components included in the composition, such as a curing agent.

[0070] Moisture-curable prepolymers are known to those skilled in the art and are commercially available.

[0071] In a preferred embodiment of the curable two-component system according to the invention, the wet-curable prepolymer is a silyl-modified prepolymer. When 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 regarding 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 coethers, silyl-modified polyisobutylene (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0072] Preferably, the silyl-modified prepolymer has a non-organosilicon backbone, and more preferably, the silyl-modified prepolymer has a polyether backbone. For example, the silyl-modified prepolymer can be a dimethoxysilyl-modified polymer, a trimethoxysilyl-modified polymer, or a triethoxysilyl-modified polymer. For example, the silyl-modified prepolymer can be a silyl-modified polyether or a copolyether.

[0073] The preferred silyl-modified prepolymer according to the present invention is selected from...

[0074] - Silyl-modified polyethers or coethers, preferably silyl-terminated polyethers or coethers, such as silyl-modified polyethylene glycol and silyl-modified polypropylene glycol;
