| Abstract: | Several factors effecting the physical properties and production of anion PU aquoemulsion are discussed, PU aquo-emulsions with storing stability and higher strength was prepared by properly processes of prepolymerizing, neutralizing, emulsifing and chain-extending. In this preparation,NCO/OH ratio is 1. 3~ 1. 8, carboxyl content is 1. 6% or more and amount of crosslinking agent is 1. 5 % ~2. 5 % . |
