Definitions
- the present invention relates to processes for the preparation of a two-component polyurethane composition comprising one or more polar solvent-soluble additives, in particular biocides. It further relates to two-component polyurethane compositions comprising one or more polar solvent-soluble additives, in particular biocides obtainable by one of the processes according to the invention, and to the use of two-component polyurethane compositions comprising one or more polar solvent-soluble additives, in particular biocides, for the production of foams and adhesives.
- Foaming can only be stably mixed in aqueous systems or one-component polyurethane compositions with a high water content.
- adhesives mixing was possible only in hydrogels or aqueous dispersions. With the exception of the hydrogels, a complex drying step is necessary in all other cases.
- the reaction between isocyanate and water competes with the reaction between isocyanate and polyols. For the modifiability, such as the adjustment of the physical and mechanical properties of two-component polyurethanes therefore a small amount of water is desired.
- the equipment of adhesives and absorbent foams with additives dissolved in polar solvents in particular with biocides dissolved in aqueous solution such as DMDM hydantoin, cetylpyridinium chloride, polyhexamethylene biguanide (PHMB) derivatives thereof or mixtures thereof or biocides dissolved in alcoholic solutions such as clioquinol, triclosan and Triphenylmethane dyes, their derivatives and mixtures thereof are used for versatile applications in medical technology; needed.
- biocides dissolved in aqueous solution such as DMDM hydantoin, cetylpyridinium chloride, polyhexamethylene biguanide (PHMB) derivatives thereof or mixtures thereof
- biocides dissolved in alcoholic solutions such as clioquinol, triclosan and Triphenylmethane dyes, their derivatives and mixtures thereof are used for versatile applications in medical technology; needed.
- hydrophilic, absorbent wound foams which are intended to receive infected wound exudate from the wound, are preferably provided with biocides in order to be able to kill the ingested microorganisms.
- Biocide-treated adhesives also have a wide range of applications in medical technology and are always used when a biocidal effect is required in addition to the combination of two substrates. This is the case, for example, with incision films or with catheter patches.
- a formulation described in WO 2011/015568 was used, which is particularly suitable for the uptake and binding of wound exudate because of the high proportion of hydrophilic polymers.
- the total water content in the polyol here is less than 5%.
- Direct mixing of a 20% aqueous PHMB solution in the final biocidal concentration into the polyol mixture immediately resulted in precipitation and the formation of a sticky PHMB sediment (Comparative Example 1). Interference of the PHMB solution in a lower concentration would be possible without precipitation, however, the necessary biocidally effective final concentration of, for example, 0.15% based on the polyurethane foam is not achieved.
- EP 2 338 923 A1 describes a polyurethane which contains a polyurea of two terminal isocyanates and a biocidal guanidinium as comonomer.
- foams for mattresses can be produced from the polyurethanes.
- the biocidal additive is incorporated directly into the polymer matrix and ensures a biocidal effect on the surface of the polymer.
- Disadvantages of EP 2 338 923 AI are that on the one hand for the achievement of the biocidal effect, a high concentration of guanidinium (about 3%) must be used and, secondly, that during the incorporation of the biocide remote action by release of the additives is not possible , as required for example in wound foams.
- WO 93/02717 A1 and US Pat. No. 5,717,500 A describe the incorporation of chlorhexidine gluconate or other aqueous solutions containing biocides into aqueous dispersion adhesives which have to be applied to, for example, polyurethane films and then dried to achieve the bond strength.
- biocidal hydrogel adhesives are known as "sandwich s - used components in absorbent wound dressings.
- the use of hydrogel adhesives here have the disadvantage that they tend to dry out due to their high water content during use on the patient and thus the release and the effectiveness of the biocidal components are adversely affected.
- the production of antimicrobial hydrogel adhesives is very time consuming due to the long crosslinking and pot lives.
- the processes according to the invention are suitable for incorporating solutions of polar solvents, in particular aqueous or alcoholic solutions, containing polar solvent-soluble additives into a two-component polyurethane composition, without encountering the stated disadvantages of the prior art.
