Definitions
- the present invention relates to specific aminoalkyl-functional alkoxysiloxane oligomer mixtures, processes for their preparation and their use in adhesives and sealants.
- Monomeric organofunctional silanes have been used successfully for many years to formulate adhesives and sealants. Especially in moisture crosslinking, so-called reactive adhesives and sealants, such.
- reactive adhesives and sealants such.
- silicones or in (alkoxysilane) -terminated polymers, such as polyurethanes or polyethers amino-functional alkoxysilanes have proven to be efficient adhesion promoters.
- Adhesion agents succeed in improving the adhesion to the substrate to be bonded / sealed. At the same time, the cohesion within the adhesive and sealant is increased. For the sealing / gluing of generally difficult
- EP 0 997 469 A2 and EP 1 304 345 A2 generally disclose aminoalkylalkoxysiloxane-containing mixtures.
- EP 0 997 469 A2 discloses two specific examples of a 3-aminopropyl / n-propyl / methoxy-siloxane oligomer mixture and an N-aminoethyl-3-aminopropyl / n-propylmethoxysiloxane oligomer mixture

- AMMO 3-aminopropyltrimethoxysilane
- the components A and B are used in a molar ratio of 1 to 0 to 1 to 7, for example 10 to 1 to 1 to 6, in particular 9 to 1, 8 to 1, 7 to 1, 6 to 1 , 5 to 1, 4 to 1, 3 to 1, 2 to 1, 1 to 1, 1 to 2, 1 to 3, 1 to 4, 1 to 5 - to name but a few advantageous feed ratios.
- the process according to the invention is carried out as follows:
- component (s) A and, optionally, component B are initially introduced. It is also possible to submit a mixture of the components concerned. In addition, however, one or both components can also be initially introduced and hydrolyzed, preferably partially hydrolyzed, and then the remaining amounts of the other component (s) added and the hydrolysis continued.
- the present alkoxysilane mixture is thus advantageous with the addition of 0.1 to 0.5 times the amount by weight, preferably 0.1 to 0.3 times the amount by weight of methanol and / or ethanol, based on the alkoxysilanes used over a period of up to about 30 Diluted in minutes.
- the metered amount of alcohol may be aqueous and the reaction mixture is advantageously mixed.
- the total calculated for the implementation if necessary still missing amount of water, suitably with good mixing, for example with stirring, and also over a period of time up to about 30 minutes.
- the reaction mixture before and / or after the alcohol, alcohol / water and / or water metering, preferably to 60 to 80 ° C., preferably 60, 62, 64, 66, 68, 70, 72, 74, 76 , 78 ° C - just to name a few of the intermediate values; the heating can also be gradual or continuous.
- the mixture is allowed to after-react for a period of 15 minutes to 5 hours, preferably for 2 to 4 hours, with thorough mixing.
- the reaction can also in the presence of a hydrolysis and condensation catalyst, such as. an addition of HCl conc.
- aqueous hydrochloric acid or sulfuric acid to name only one suitable catalyst, preferably in an amount of 0 to 0.5, preferably 0.01 to 0.3, particularly preferably 0.05 to 0.2, in particular 0.1 wt. % HCl, based on the amount of component (s) A or A used and optionally B, ie A and B, are carried out.
- the catalyst can be added, for example, together with the diluent, the diluent / water mixture and / or the water. After the reaction, the product mixture thus obtained is worked up by distillation in a particularly gentle manner. In this case, the present proportion of methanol and / or ethanol is usually almost completely separated.
- aminopropyl-functional alkoxysiloxane oligomer mixtures which in the case of cocondensates, for example, a statistical Distribution or block distribution of different functional [(R) 2 Si (O) 2/2 ] units and terminal units [-Oi 2 Si (R) 3] have.
- a mixture of the invention and also branched siloxane oligomers with units [(R) Si (O-) 3/2] contain, ie siloxane oligomers which also contain T-structures besides sg M- and D-structures.
- M, D, T and Q structures usually refers to the number of bound oxygens, as exemplified below by means of silylic units:
- T trifunctional units [(R) Si (O-) 3/2]
- compositions of units D and M are required for building chains, so that trimers ( M 2 D), tetramers (M 2 D 2 ) and so forth can be built up to linear oligomers with M 2 D n
- building units D are required
- rings with D 3 , D, . D be established 5 or higher branched or crosslinked structure elements, including spiro compounds are expected to be obtained when units T and / or Q are present together
- Possible cross-linked structures may be used as T n (n>4);.
- Units of construction M are also referred to as stoppers or controllers
- D units are referred to as chain or ring former
- the T and possibly also the Q units as network formers.
- M, D, T or Q structures is generally determined by a method known per se to the person skilled in the art, preferably by means of 29 Si NMR.
- the present process is particularly selective and gentle on the product for the preparation of the specific mixtures according to the invention of homocondensed or co-condensed aminopropyl-functional alkoxysiloxane oligomers, as they can be found idealized formulas I and II.
- a mixture according to the invention in adhesives and / or in sealants, d. H. especially in corresponding moisture-curing adhesive or sealant compositions.
- mixtures according to the invention in adhesive or sealant compositions, preferably for bonding wood, glass, metals, plastics, painted surfaces and / or mineral substrates, in particular for bonding metal and plastic parts, bonding of several plastic parts, bonding of wood and plastic parts, bonding of glass and metal and / or plastic parts, bonding of mineral substrates and metals and / or plastic parts, very particularly preferably adhesions in which aluminum is used as the metal and as a plastic polyolefin, polycarbonate and / or poly ( meth) acrylate, polyvinyl chloride, polycarbonate and / or polymethylmethacrylate.
- adhesive or sealant compositions for bonding in the interior and exterior, especially for applications in vehicle, container, apparatus and shipbuilding, in the interior of real estate and in window and door construction, and also particularly advantageous for the gluing in the production of protective glazing, Sandwichverklebisme, lamp covers, lamp holders, switch parts, control knobs and in window construction.
- adhesive and sealant compositions are very stable on storage in the absence of moisture and harden after application to the substrates to be bonded under the influence of moisture. As a rule, the humidity is sufficient to cause the crosslinking of the adhesives and sealants.
- Said adhesives and sealants are very good and easy to process. After application to the substrates skin formation occurs. At 23 ° C and 50% relative humidity, skin typically forms within 1 to 200 minutes. The duration of the curing depends inter alia on the thickness of the desired adhesive bond. Typically, through-curing takes place in a layer of 1 to 5 mm within 24 hours.
- the bonds produced are also characterized by excellent mechanical properties and excellent adhesion.
- Through-hardened bonds typically have moduli of elasticity of 0.2 to 10 N / mm 2 , as well as tensile strengths of 1 to 10 N / mm 2 , ultimate elongations of 100 to 1000% and Shore A hardnesses of 20 to 90.
- mixtures of the invention are surprisingly particularly advantageous in the improvement of adhesives and sealants.
