- Two-component polyurethane adhesives usually consist of one component containing an NCO-containing compound and a second component providing an H-acidic reactant.
- the NCO-containing component may contain any of the above-mentioned, suitable for the prepolymer preparation di- or polyisocyanates. It may also contain one or more prepolymers already described for use in one-part adhesives.
- the second component contains one or more H-acidic components.
- these can be the same compounds as are used in the preparation of prepolymers, ie in particular di- or polyfunctional alcohols, amines, mercaptans or carboxylic acids. In most cases, longer-chain, polymeric diols or polyols are used for this purpose.
- the first component contains an NCO-containing prepolymer, short-chain compounds such as dihydric or trifunctional alcohols and amines or water are frequently used as reactants.
- the mixing ratio of the components of a 2K system depends essentially on the chosen NCO-containing and H-acidic reactants or their molecular weight. It can move in a range between about 100: 1 and 1:10. Many products use one of the two components in excess. However, it is readily possible for the skilled person also to formulate adhesives with a mixing ratio of 1: 1. Such products are also commercially available.
- silane-crosslinking polymers generally have an organic backbone, which at the ends z. B. carries alkoxy or Acyloxysilyl phenomenon. In the presence of atmospheric moisture, those polymers which have silyl groups with hydrolyzable substituents are able to condense with each other at room temperature.
- an alkoxy- and / or acyloxysilane-terminated polymer having at least one end group of the general formula (I)
- A is a divalent linking group
- R is a divalent, optionally containing a heteroatom, hydrocarbon radical having 1 to 12 carbon atoms, and
- X, Y, Z are C 1 -C 8 -alkyl, C 1 -C 6 -alkoxy or C 1 -C 8 -acyloxy radicals, where at least one of the
- the bivalent binder group A is a divalent chemical group which links the polymer skeleton of the alkoxy- and / or acyloxysilane-terminated polymer with the radical R of the end group.
- the divalent linking group A can be formed, for example, in the preparation of the alkoxy- and / or acyloxysilane-terminated polymer, e.g. as a urethane group by the reaction of a hydroxy-functionalized polyether with an isocyanato-functional alkoxysilane.
- Isocyanato-functional alkoxysilanes are short-chain, monomeric compounds having a terminal silyl group in the sense of the above definition, which contain an isocyanate function (-NCO) at at least one further point in the molecule.
- -NCO isocyanate function
- n 0 or 1
- the radical R is a divalent, optionally containing a heteroatom hydrocarbon radical having 1 to 12 carbon atoms.
- heteroatom for example, oxygen (O) or nitrogen (N) may be included.
- the hydrocarbon radical may be, for example, a straight-chain chain or branched or cyclic, substituted or unsubstituted alkylene radical.
- the hydrocarbon radical may be saturated or unsaturated.
- X, Y and Z are independently C 1 -C 6 -alkyl radicals, C 1 -C 6 -alkoxy radicals or C 1 -C 8 -acyloxy radicals. At least one of the radicals X, Y, Z must be a hydrolyzable group, ie a C 1 -C 8 -alkoxy group or a C 1 -C 8 -acyloxy group.
- hydrolyzable groups preference is given to alkoxy groups, in particular methoxy or ethoxy groups. This is advantageous since no substances irritating the mucous membranes are released during the curing of compositions containing alkoxy groups. The alcohols formed are harmless in the released amounts and evaporate.
- acyloxy groups such as an acetoxy group -O-CO-CH 3 can also be used.
- the alkoxy- and / or acyloxysilane-terminated polymer has at least two terminal groups of the general formula (I).
- Each polymer chain thus contains at least two linkage sites, where the condensation of the polymers can take place with elimination of the hydrolyzed radicals in the presence of atmospheric moisture.
- X, Y and Z are a methyl or a methoxy group.
- X, Y and Z are a methyl or a methoxy group.
- compounds having alkoxysilyl groups have different reactivities in chemical reactions. Within the alkoxy groups, the methoxy group shows the greatest reactivity. It is therefore possible to resort to such silyl groups if a particularly rapid curing is desired.
- Higher aliphatic radicals such as ethoxy bring about a lower reactivity of the terminal alkoxysilyl group compared to methoxy groups and can advantageously be used for the development of graduated crosslinking rates.
- R is a hydrocarbon radical having 1 to 6 C atoms, in particular having 1 to 3 C atoms.
- the curing speed can be be influenced composition of the composition, whereby a further design possibility for the silane-crosslinking adhesive according to the invention is opened.
- R is a methylene, ethylene or propylene radical.
- R is a methylene, ethylene or propylene radical.
- Particular preference is given to using methylene and 1,3-propylene radicals.
- Alkoxysilane-terminated compounds having a methylene group as a link to the polymer backbone - so-called ⁇ -silanes - have a particularly high reactivity of the final silyl group, which leads to shortened setting times and thus to a very rapid curing of formulations based on such polymers.
- an extension of the connecting hydrocarbon chain leads to a reduced reactivity of the polymers.
- the ⁇ -silanes - they contain the unbranched propylene radical as a link - have a balance between necessary reactivity (acceptable curing times) and delayed curing (open time, possibility of correction after bonding) on.
- A is an amide, carbamate, urea, imino, carboxylate, carbamoyl, amidino, carbonate, sulfonate or sulfinate group or an oxygen or nitrogen atom.
- the binding group A can be formed in the preparation of the silyl-terminated polymers by reacting the framework polymer with a reactive compound bearing the -R-SiXYZ sequence.
- Group A may be both distinguishable and indistinguishable from structural features occurring in the underlying polymer backbone. The latter is, for example, if it is identical to the points of attachment of the repeat units of the polymer backbone. In this case, n would correspond to the value 0. If the binding group A is distinguishable from the linking groups in the polymer backbone, n corresponds to the value 1.
- a suitable silyl group-containing monomer is, for example, vinyltrimethoxysilane.
- Another method is the grafting of unsaturated monomers such. For example, vinyltrimethoxysilane on thermoplastics, such as polyethylene.
- hydrosilylation the addition of silanes or H-silanes such as methyldimethoxysilane to carbon-carbon double bonds under noble metal catalysis.
- urethane and urea groups which can be obtained by reacting certain functional groups of a prepolymer with an organosilane which carries a further functional group.
- Urethane groups can, for. B. arise when either the polymer backbone contains terminal hydroxyl groups and as a further component isocyanatofunctional alkoxysilanes, which are also referred to as isocyanatosilanes, are used, or conversely, if a polymer having terminal isocyanate nat phenomenon, with a terminal hydroxyl-containing alkoxysilane (hydroxy) functional alkoxysilane) is reacted.
- urea groups can be obtained when a terminal primary or secondary amino group - either silane or polymer - is used which reacts with a terminal isocyanate group present in each reactant. That is, either an amino-functional alkoxysilane (aminosilane) having a terminal isocyanate group-containing polymer or a terminal amino-substituted polymer is reacted with an isocyanato-functional alkoxysilane.
- Urethane and urea groups advantageously increase the strength of the polymer chains and the entire crosslinked polymer because they can form hydrogen bonds.
- the alkoxy- and / or acyloxysilane-terminated polymer has a polyether or polyurethane backbone and the binder group A is a urethane or urea group, wherein the alkoxy- and / or acyloxysilane-terminated polymer preferably has two end groups of the general formula (I ), which have di- or trimethoxysilyl radicals, for example di- or trimethoxysilylpropyl radicals, di- or trimethoxysilylmethyl radicals.
- di- or trimethoxysilyl radicals for example di- or trimethoxysilylpropyl radicals, di- or trimethoxysilylmethyl radicals.
- the alkoxy- and / or acyloxysilane-terminated polymer has a molecular weight M n of from 4,000 to 60,000, preferably from 8,000 to 20,000.
- Two-component systems based on reactive, silane-functional binders can also be formulated. Since the crosslinking of these binders takes place via a polycondensation, and not - as in the case of polyurethanes - via a polyaddition, there is no broad range of reaction partners available.

This shows the higher damping effect of the adhesives 6, 7 and 11 compared to Comparative Example 13 in the range of room temperature. It can clearly be seen that Example 7 (with paraffinic-naphthenic oil instead of diisononyl phthalate) has a particularly advantageous peak height. Example 11 (with ternary blend of SIS copolymer, paraffinic-naphthenic oil, and hydrocarbon resin) shows improved peak width.
