Abstract
Die vorliegende Erfindung betrifft eine Aminoharz-Dispersion, umfassend eine disperse und eine kontinuierliche Phase, wobei entweder (a) die disperse Phase eine hydrophobe Komponente auf Aminoharzbasis und die kontinuierliche Phase ein in einem polaren Loesungsmittel geloestes, hydrophiles Aminoharz enthaelt oder (b) umgekehrt. Bevorzugt enthaelt die Aminoharz-Dispersion weiterhin einen hydrophilen Epoxidharzester. Ueberraschenderweise koennen Dispersionen, die einen solchen Ester enthalten, naemlich besonders stabil und ausserdem extrem stark verduennbar sein. Die erfindungsgemaessen Aminoharz-Dispersionen eignen sich beispielsweise zur Herstellung von dekorativen Oberflaechen, von Platten oder von technischen Laminaten.
DE 10226789 A UPAB: 20040218 NOVELTY - An amino resin dispersion including a disperse phase and a continuous phase containing hydrophilic and hydrophobic components where the disperse phase contains a hydrophobic component based on amino resin and the continuous phase a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent, or the continuous phase contains a hydrophobic phase based on amino resin and the disperse phase contains a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent is new. DETAILED DESCRIPTION - An amino resin dispersion including a disperse phase and a continuous phase, where either (a) the disperse phase contains or consists of a hydrophobic component based on amino resin and the continuous phase comprises a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent, or (b) the continuous phase contains or is a hydrophobic phase based on amino resin and the disperse phase is or contains a hydrophilic amino resin or a precondensate of this dissolved in a polar solvent is new. INDEPENDENT CLAIMS are included for: (1) a method for preparation of the dispersion by introduction of the hydrophilic amino resin dissolved in a polar solvent or a precondensate of this optionally in the presence of one or more additives, and dispersion in the mixture of the amino resin based hydrophobic component; (2) a cured aminoplast obtainable by curing the amino resin dispersion. USE - The amino resin dispersion is useful in the preparation of decorative surfaces, boards, or commercial laminates (claimed). ADVANTAGE - The polymer dispersion has a decreased volatiles and increased polymer content.
