Abstract
A one-component dispersion comprising deactivated isocyanates which cross-links already at low temperatures (lower than 70 °C).
Description
Substance System The present invention relates to a storage-stable, cross-linkable aqueous one-component dispersion.
Nowadays, high performance adhesive bondings are achieved according to the state of the art with reactive adhesives. For this purpose, a series of different adhesive sys-tems is known. Due to their high reactivity, polyisocyanates are used for many appli-cations in this field.
There are, for example, isocyanate-terminated polymers which cross-link after the application with moisture. The disadvantage of these systems is that curing takes a long time since cross-linking is dependent on the diffusion rate of water.
Furthermore, cross-linking can remain incomplete in the case of very thick layers.
Two-component adhesives are mixed immediately before their application, which comprises an additional step for the user. Moreover, while preparing the two-compo-nent systems, errors may occur in proportioning or in mixing.
Further, one-component systems are known which may be formulated by blocking isocyanates with monofunctional reactants. Said blocking is thermally reversible, so that at elevated temperatures the blocking agent is separated and the released isocyanate forms a thermostable bond with the reactive polymer groups by cross-lin-king.
The disadvantage of these systems is that, if said blocking agent is volatile at applica-tion temperature, it vaporizes and may thus burden the environment or, if said bloc-king agent remains in the adhesives, it may lead to a deterioration or degradation as to the duality of said adhesives.
EP 0 204 970 discloses a process for the production of stable dispersions of fine powdered polyisocyanates in a liquid by treating said polyisocyanates with stabili-zing agents. In order to produce storage-stable dispersions of polyisocyanates and especially solid polyisocyanates and in order to prevent a premature, undesired reac-tion with the dispersion medium, the dispersed isocyanates are deactivated on their surface. They then possess a so-called retarded reactivity.

In order to produce storage-stable dispersions of polyisocyanates and especially solid polyisocyanates and in order to prevent a premature, undesired reac-tion with the dispersion medium, the dispersed isocyanates are deactivated on their surface. They then possess a so-called retarded reactivity.
EP 0 204 970 further discloses the use as a cross-linker for said stable dispersions of fine powdered polyisocyanates produced according to the process of said document. The stabilization of the polyisocyanates is obtained by the application of a polymeric shell. The compounds used to enable this polymeric shell are called stabilizing agents. The deactivated polyisocyanates, which comprise said polymer shell, are called stabilized polyisocyanates. The disadvantage here is that the burst or break-up of the polyurea capsules and~thus cross-linking occurs at a temperature between 70 and 180°C.
The present invention provides a one-component dispersion cross-linking at low temperatures.
In one aspect, the invention provides a storage-stable, cross-linkable aqueous one-component dispersion, comprising: (a) a solid diisocyanate which has been surface-deactivated or encapsulated with an amine selected from the group consisting of di- and polyamines so as to have a retarded reactivity, said surface-deactivated or encapsulated diisocyanate being present in an amount within a range of 0.1% by weight to 10% by weight based on the total weight of the aqueous dispersion and being selected from the group consisting of a toluene-diisocyanate (TDI), TDI-urethdione, TDI-urea and 4,4'-methylene-di(phenylisocyanate) (MDI); and (b) a polyurethane based dispersion adhesive as a polymer component, wherein a film produced from the aqueous dispersion is cross-linkable at 20°C, 65% relative humidity without heating.
Applicants surprisingly found out that the use of encapsulated or deactivated isocyanates, which are known per se, as cross-linking agents in aqueous dispersions leads 2a to storage-stable systems cross-linking already at temperatures lower than 70°C.
It is assumed that the self-adhesion forces arising during the formation of the polymeric film mechanically destroy the polymeric shells of the isocyanates, thus leading to a cross-linking reaction which can be shown on the basis of the increase of film cohesion or the reduction of film elasticity, respectively.
The one-component dispersion according to the present invention has the advantage that it cross-links at relatively low temperatures, especially at room temperature, thereby avoiding the disadvantages of stable prior art one-component systems. Compared with prior art two-component adhesives, the one-component dispersions of the present invention provide the advantage that they exclude the possibility of errors in application by the user, e.g.
proportioning or mixing errors.
According to one embodiment of the present invention, the amounts of deactivated isocyanates in the one-component dispersions of the present invention are within the range of from 0.1% by weight up to 20% by weight, and especially of from 1% by weight up to 10% by weight.

The one-component dispersions of the present invention may be used in a multitude of applications, e.g. as a paint or a lacquer, as a coating, as a sealing material, as a cas-ting material and/or as an adhesive.
When used as an adhesive, a suitable dispersion adhesive according to the present invention may contain, for example, Dispercoll~ KA 8758. According to the present invention, suitable isocyanates are, for example, MDI or TDI, such as TDI-urethdione or TDI-urea. These isocyanates are deactivated according to the method known per se, and the resulting deactivated isocyanates are then added to an appropriate poly-mer such as a dispersion adhesive, while stirring. When the deactivated isocyanate is homogeneously and smoothly incorporated, the one-component dispersion of the present invention is ready to be used.
The one-component dispersion of the present invention can advantageously be used, for instance, for the bonding of three dimensional furniture fronts. These types of furniture fronts are produced in such a way, nowadays, that a plastic film or foil is pressed to a contoured .medium density fiberboard carrier under pressure while app-lying heat, so that the film or foil takes the shape or the contours of the medium den-sity fiberboard surface. The friction-type bond between the two substrates requires an adhesive which has previously been applied to the carrier. It is known that in or-der to realize high performance bonding with good heat stability, two-component polyurethane dispersion systems are used, wherein the aqueous dispersion is mixed with the water-emulsible polyisocyanate immediately before use. Due to propor-tioning errors or insufficient homogenization an optimal heat stability cannot be re-ached. Furthermore, the pot-life of these two-component systems is limited to a few hours anly.
The above-mentioned disadvantages can advantageously be avoided or at least mitigated by using the one-component dispersion adhesive of the present invention.
Examples are described in the following.
Gesthuysen, von Rohr & Eggert - 4 -Example 1: Synthesis of deactivated isocyanates Example 1.1:
100 ml of cyclohexane are placed into a beaker and 20 g of a TDI-urethdione (Desmodur~ TT, Bayer AG) are suspended while strongly stirring. Then, a solution of 0.06 g of methylpentamethylenediamine (Dytek~ A, DuPont) in 50 ml of cyclo-hexane is added. After a stirring time of two hours, the resulting solution is removed from the solvent so that a fine, white powder is obtained.
Example 1.2:
The synthesis process corresponds to that of Example 1.1, however, a TDI-urea (Desmodur~ LS 2116, Bayer AG) is used instead of said TDI-urethdione.
Example 2: Production and cross-linking of one-component dispersion adhe-sives The deactivated isocyanates from Examples 1.1 and 1.2 are added to Dispercoll~
KA
8758 while stirring. Stirring should continue until the isocyanates are homogeneously and smoothly incorporated.
The cross-linking of the storage-stable one-component dispersion adhesives at room temperature is clearly shown in the following examples:
