Description

Wa12325S / WI Crosslinkable compositions based on organyloxysilane-terminated polymers The invention relates to crosslinkable compositions of silane-crosslinking prepolymers, to processes for their preparation and to their use in adhesives and sealants, in particular in adhesives which are characterized by the combination of high tear strength with high elongation at break. Polymer systems which have reactive alkoxysilyl groups have been known for a long time. Upon contact with water or atmospheric moisture, these alkoxysilane-terminated polymers are capable of condensing with one another, with the alkoxy groups being eliminated, even at room temperature. One of the most important applications of such materials is the production of adhesives and sealants. Adhesives based on alkoxysilane-crosslinking polymers, for example, exhibit very good adhesion properties to many substrates when cured.A further advantage of silane-curing systems over numerous other adhesive and sealant technologies (e.g., over isocyanate-curing systems) is the toxicological safety of the prepolymers. Alkoxysilane-curing polymers can be used in both one- and two-component systems (1K and 2K systems). The latter usually contain the curable polymer in one component and water as a curing reagent in the second component. Such systems are particularly advantageous when non-porous substrates are to be bonded over large areas. In most applications, however, one-component systems (1K systems) are preferred, which cure upon contact with atmospheric moisture. The key advantages of one-component systems... Wa12325S / WI 2 The main advantages are their very easy application, as the user does not need to mix different adhesive components. In addition to saving time and effort and reliably avoiding potential dosing errors, single-component systems also eliminate the need to process the adhesive / sealant within a usually very narrow time window, as is the case with multi-component systems after the two components have been thoroughly mixed. A disadvantage of many state-of-the-art systems is the moderate reactivity of the corresponding polymers towards moisture, which requires aggressive catalysis. The corresponding mixtures therefore typically contain tin catalysts that are toxicologically questionable.The use of so-called α-silane-terminated prepolymers, which possess reactive alkoxysilyl groups linked to a neighboring urethane unit by a methylene spacer, is advantageous here. This class of compounds is highly reactive and requires neither tin catalysts nor strong acids or bases to achieve high curing rates upon contact with air. Commercially available α-silane-terminated prepolymers include GENIOSIL. ® STP-E10 or -E30 from Wacker-Chemie AG. In addition to their easy application and good adhesion profile, both conventional and β-silane-curing binders are characterized by very interesting mechanical properties. They are ideally suited for use in low-modulus sealants with high elasticity. In combination with reinforcing fillers, they can also be used to produce so-called elastic adhesives. Wa12325S / WI 3 which combine moderate hardness and tear strength with still high elasticity. Very hard adhesives, which are characterized by high tensile shear strength or high tear strength, cannot be produced with conventional alkoxysilane-crosslinking systems. Typical tear strengths are between 1 and 3 MPa; more than 4 MPa can hardly be achieved even in combination with large amounts of reinforcing fillers. The same applies to the tensile shear strength. This represents a massive limitation for applications that require adhesives with high tear resistance rather than elasticity. A better option here is a special variant of adhesives based on alkoxysilane-crosslinking polymers, as described in WO 2013 / 026654. The formulations described there contain, in addition to the silane-crosslinking polymers, also larger amounts of methoxy-functional, i.e. also crosslinkable, phenylsilicone resins.These resin additives result in adhesives that, once fully cured, exhibit significantly improved hardness and tensile shear strength. A disadvantage of these systems, however, is the very low elasticity of the corresponding resin-based adhesive systems once cured. The elongation at break in such systems is well below 200%, often even below 50%. While the resin additive has a positive effect on hardness and tensile shear strength, its effect on elasticity is negative. While this is not relevant for all applications, highly tear-resistant adhesives with high elasticity are particularly desirable for elastic bonding. This is, among other things, the case when... Wa12325S / WI 4 is the case when materials with different thermal expansion are bonded together over a wide area, or for many adhesive applications in automotive manufacturing, e.g. in body construction, when bonding dashboards, headlights, or windshields. Here, a combination of high tear strength with high elasticity is generally required. In addition, high elasticities often also improve the tear strength of the corresponding adhesives, since with a comparable modulus, greater elongation is possible before the adhesive breaks. And an elongation at break that is even improved compared to the technology described in WO 2013 / 026654 is of course also desirable for numerous applications, and often even necessary, e.g., for wood bonding, which must comply with the so-called D4 standard.One approach to producing silane-curing adhesive formulations that are both highly tear-resistant and highly elastic is described in WO2017 / 137281. The adhesive systems presented there contain, in addition to silane-terminated polymers and phenylsilicone resins, carbon black as a third mandatory component. However, even though this combination represents a significant improvement, the formulations specifically described in WO2017 / 137281 exhibit typical tear strengths between 5 and 6 MPa, with the highest achievable tear strength being 6.8 MPa. This is insufficient for many applications, e.g., for the aforementioned D4 wood adhesives or for windshield bonding. Furthermore, the systems described in WO2017 / 137281 contain carbon black and are accordingly deep black. Adhesives of other colors, light-colored, or even transparent ones, cannot be produced in this way. Wa12325S / WI 5 This represents a significant disadvantage because, when the substrates to be bonded are pressed together, small amounts of adhesive often escape from the bonding gap. Unless two black substrates are bonded by chance, black adhesives are therefore unsuitable for visually demanding applications. The object of the invention was therefore to provide an improved technological approach with which non-black adhesives are accessible which combine high elasticity with high elongation at break. A particularly advantageous solution to this problem should also offer the adhesive manufacturer the possibility of being able to provide transparent or semi-transparent and also largely colorless adhesives. The invention relates to crosslinkable compositions (M) comprising (A) 100 parts by weight of compounds (A) of the formula Y-[(CR 1 2)b-SiRa(OR 2)3-a]x (I), where Y is an x-valent polymer radical bonded via nitrogen, oxygen, sulfur or carbon, R can be the same or different and is a monovalent, optionally substituted, SiC-bonded hydrocarbon radical, R 1 may be the same or different and represents a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical which may be bonded to the carbon atom via nitrogen, phosphorus, oxygen, sulfur or carbonyl group, Wa12325S / WI 6 R 2can be the same or different and represents a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, x is an integer from 1 to 10, preferably 1, 2 or 3, particularly preferably 1 or 2, a can be the same or different and is 0, 1 or 2, preferably 0 or 1, and b can be the same or different and is an integer from 1 to 10, preferably 1, 3 or 4, particularly preferably 1 or 3, in particular 1, and (B) more than 10, preferably more than 50, parts by weight of silicone resins (B) containing units of the formula R 3 c(R 4 O)dR 5 eSiO(4-cde) / 2 (II), where R 3 may be the same or different and denotes a hydrogen atom, a monovalent, SiC-bonded, optionally substituted aliphatic hydrocarbon radical or a divalent, optionally substituted, aliphatic hydrocarbon radical bridging two units of the formula (II), R 4may be the same or different and represents a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, R 5 may be the same or different and represents a monovalent, SiC-bonded, optionally substituted aromatic hydrocarbon radical, c is 0, 1, 2 or 3, d is 0, 1, 2 or 3, preferably 0, 1 or 2, particularly preferably 0 or 1, and e is 0, 1 or 2, preferably 0 or 1, Wa12325S / WI 7 with the provisos, ^ that the sum of c+d+e is less than or equal to 3, ^ that in at least 60% of the units of the formula (II) the sum c+e is 0 or 1, where preferably in at least 40% of the units of the formula (II) e is 1 and c is 0, ^ that at least 70 mol%, preferably at least 80 mol%, particularly preferably at least 90 mol% of all radicals R 2which are contained in component (A) are methyl radicals, ^ that at least 60 mol%, preferably at least 75 mol%, particularly preferably at least 90 mol% of all radicals R 4 , which are contained in the silicone resins (B), represent ethyl radicals, ^ that at most 30 mol%, preferably at most 20 mol%, particularly preferably at most 10 mol% of all radicals R 4which are contained in the silicone resins (B) are methyl radicals. The invention is based on the surprising discovery that the combination of methoxy-functional silane-terminated polymers (A) with silicone resins (B) whose alkoxy groups consist predominantly of ethoxy groups and which contain no or only a few methoxy groups, exhibit significantly better mechanical properties, in particular significantly higher elasticities and in some cases also higher tear strengths, than is the case with combinations of silane-terminated polymers and silicone resins, as described, for example, in WO 2013 / 026654, and which do not have this special combination of alkoxy groups contained in the polymers (A) and the silicone resins (B). This discovery is all the more surprising given that all the alkoxy groups are removed during the curing of the corresponding mixtures Wa12325S / WI 8 are split off, evaporate and thus are no longer present in the fully cured mixture. This means that the fully cured mixtures consist of exactly the same building blocks regardless of which alkoxysilyl groups components (A) and (B) originally had. And of course, the person skilled in the art expects that two materials composed of exactly the same building blocks will also have largely identical properties. In the case of the present invention, however, this expectation is disappointed.

Composite molded parts here are to be understood as meaning a uniform molded article made of a composite material which is composed of a crosslinking product of the compositions according to the invention and at least one substrate in such a way that a strong, permanent bond exists between the two parts. The compositions (M) according to the invention have the advantage that they are easy to produce.

Furthermore, the crosslinkable compositions (M) of the invention have the advantage of being easy to process. Furthermore, the crosslinkable compositions (M) of the invention have the advantage that they can be used to produce adhesives with high tear strength combined with high elongation at break.

The skilled reader should, however, understand this type of disclosure to mean that any combination of different levels of preference is explicitly disclosed and explicitly desired. In the examples described below, to which the invention is not intended to be limited, all viscosity data relate to a temperature of 25°C.Unless otherwise stated, the following examples are carried out at ambient atmospheric pressure, i.e., approximately 1000 hPa, and at room temperature, i.e., approximately 23°C, or at a temperature that occurs when the reactants are combined at room temperature without additional heating or cooling, and at a relative humidity of approximately 50%. Furthermore, all parts and percentages are by weight unless otherwise stated. Wa12325S / WI 39 Examples Synthesis Example 1: Preparation of a Resin Not According to the Invention 1000 g of phenyltrimethoxysilane are placed at room temperature in a 2 l four-necked flask fitted with a dropping funnel, Liebig condenser, KPG stirrer and thermometer. 20 g of 20% aqueous hydrochloric acid are added while stirring. The mixture is then heated to 65–68°C until gentle reflux sets in. A mixture of 76 g of water and 20 g of methanol is then added evenly over a period of 30 minutes under reflux. After the addition is complete, the mixture is stirred under reflux for a further 10 minutes and then cooled to room temperature. The reaction mixture is left to stand for approximately 16 hours at room temperature, then 60 g of sodium bicarbonate are added while stirring, the mixture is stirred for 30 minutes and the resulting solid is separated off by filtration. Finally, the low boilers (mainly methanol) are removed by distillation. Initially, approx.80-90% of the distillate quantity to be removed is removed at 1013 mbar and a temperature of 120°C, then the pressure is reduced to 10 mbar and the remaining low-boiling residues are distilled off over the next 15-20 minutes. This gives a methoxy-functional phenylsilicone resin with an average molecular weight Mn of 1200 g / mol, a viscosity of 50 mPas at 23°C and a methoxy group content of ~17% based on the total resin mass. Synthesis Example 2: Preparation of a Resin According to the Invention The procedure is as in Example 1. However, instead of 1000 g of phenyltrimethoxysilane, an equimolar amount, i.e. Wa12325S / WI 40 1212 g of phenyltriethoxysilane and, instead of 20 g of methanol, an equimolar amount, ie 28.8 g, of ethanol are used. All other parameters (reaction temperatures, reaction times, water and sodium bicarbonate, etc.) remain unchanged. This gives a phenyl-methyl silicone resin with an average molecular weight Mn of 1100 g / mol, a viscosity of 40 mPas at 23 °C and a methoxy group content of 18% based on the total resin mass. Synthesis Example 3: Preparation of a Resin Not According to the Invention The procedure is as in Example 1, but the starting materials and amounts are varied as follows. Instead of 1000 g of phenyltrimethoxysilane, a mixture of 700 g of phenyltrimethoxysilane, 250 g of methyltrimethoxysilane and 50 g of dimethyldimethoxysilane is added.And after the unchanged addition of hydrochloric acid and heating to a temperature of 65–68°C, instead of a mixture of 76 g of water and 20 g of methanol, a mixture of 94.5 g of water and 42 g of methanol is added evenly under reflux over a period of 30 minutes. All other process parameters, starting materials, and quantities remain unchanged. Synthesis Example 4: Preparation of a Resin According to the Invention The procedure is as in Example 3. However, instead of 700 g of phenyltrimethoxysilane, an equimolar amount, ie 848.5 g, of phenyltriethoxysilane is used; instead of 250 g of methyltrimethoxysilane, an equimolar amount, ie 327.2 g, of methyltriethoxysilane is used; instead of 50 g of dimethyldimethoxysilane, an equimolar amount, ie 61.7 g, of dimethyldiethoxysilane is used; and instead of 40 g of methanol, an equimolar amount, ie 57.6 g, of ethanol is used. Wa12325S / WI 41 Parameters (reaction temperatures, reaction times, water and sodium bicarbonate, etc.) remain unchanged. A phenylsilicone resin with an average molecular weight Mn of 1400 g / mol, a viscosity of 60 mPas at 23 °C, and an ethoxy group content of ~25% based on the total resin mass is obtained. Synthesis Example 5: Preparation of Isocyanatomethyltrimethoxysilane The preparation of isocyanatomethyltrimethoxysilane takes place in a thin-film evaporator with a length of 25 cm, an inner diameter of 8 cm, and a wall temperature of 300 °C. 400 g of N-trimethoxysilylmethyl-O-methylcarbamate (commercially available under the name GENIOSIL ®0.28 g of dioctyltin dilaurate is added to a thin-film evaporator (XL 63 from Wacker Chemie AG, Munich, Germany). The mixture is added at a rate of 110 ml / h at the top of the thin-film evaporator. A nitrogen stream of 65 l / h is passed from bottom to top, i.e., against the flow direction of the reaction mixture. Under these conditions, the bottoms outflow amounts to only approximately 10% of the added silane quantity. The evaporated product mixture, together with the nitrogen stream, is passed through a 10 cm long Vigreux column insulated by a vacuum jacket, with the liquid column reflux being fed back into the thin-film evaporator. The top temperature of the Vigreux column is 158-164 °C. The thermolyzed silane mixture is selectively condensed from this gas stream using a conventional glass condenser at a temperature of 54 °C. In a second condensation step, the methanol is then condensed at a temperature Wa12325S / WI 42 condensed at a temperature of 0 °C before the nitrogen stream is passed through a cold trap into the air extraction of the fume hood in which the entire system is located. The resulting silane mixture is stored at -20 °C. The colorless liquid is 1Analyzed by H-NMR and gas chromatography. It contains 33.7% isocyanatomethyltrimethoxysilane, 66.4% N-trimethoxysilylmethyl-O-methylcarbamate, and 0.1% methanol. Subsequent fractional distillation yields 75 g of isocyanatomethyltrimethoxysilane with a purity of 98.9%.

The mixture is cooled to room temperature, and then 42.5 g of isocyanatomethyltrimethoxysilane (prepared according to Synthesis Example 5) are added. The mixture is heated to 80°C with stirring.Then 0.24 g (150 ppm) of a bismuth-containing catalyst (commercially available under the name Borchi. ® Cat 315 from Borchers GmbH, Langenfeld, Germany) is added, heating the reaction mixture to 83-84°C. The reaction mixture is stirred for a further 120 min at 80°C. Wa12325S / WI 43 The mixture is then cooled to 60°C, and 21.0 g of a polyethylene glycol with a number-average molar mass of 350 g / mol, whose molecular chains each have a methoxy- and a hydroxy-functional chain end, are added and stirred for a further 30 minutes at 60°C. No isocyanate groups can be detected in the resulting polymer mixture by IR spectroscopy. A clear, transparent polymer mixture is obtained which has a viscosity of 25 Pas at 25°C.

During curing, the formation of a skin is tested every 5 minutes. To do this, a dry laboratory spatula is carefully placed on the surface of the sample and pulled upwards. If the sample sticks to the finger, a skin has not yet formed. If no sample sticks to the finger, a skin has formed and the time is noted.
