EPOXY RESIN-AMINE ADDITION PRODUCTS FOR USE AS EMULSIFIERS FOR EPOXY RESINS; AQUEOUS BASED EPOXY RESIN DISPERSIONS AND PROCESS FOR PRODUCING THE SAME

摘要

Epoxy resin-amine addition products are obtained by reacting (A-1) at least one or several epoxy resin compounds based on polyvalent aromatic or cycloaliphatic alcohols and/or novolaks with an epoxy functionality ⊃1 and ≤4 and a mean epoxy resin equivalent weight from 70g/eq to 1,000 g/eq with at least one or several polyalkylene glycols terminated with an amino group and having a mean amine functionality from 0.5 to 1.5 and a mean molecular weight from 700 to 5,000; ≥60 % by weight ethylene oxide, relative to the total content of polyalkylene glycol and a ratio between the reactive equivalents of the amine-terminated polyalkylene glycol and polyepoxyde from 0.05:1 to 0.9:1; (A-2) at least one or several epoxy resin compounds based on polyvalent aliphatic alcohols with an epoxy functionality ⊃1 and ≤4 and a mean epoxy equivalent weight from 70 g/eq and 6,000 g/eq with at least one or several polyalkylene glycols terminated with an amino group and with a mean amine functionality from 0.5 to 1.5 and a mean molecular weight from 700 to 5,000; ≥60 % by weight ethylene oxide, relative to the total content of polyalkylene glycol and a ratio between the reactive equivalents of the amine-terminated polyalkylene glycol and polyepoxyde from 0.01:1 to 0.9:1. The mixing ratio between the one or several epoxy resin-amine addition products as per (A-1) and the one or several epoxy resin-amine addition products as per (A-2) lies between 5:95 and 95:5.
