Effects on Properties of Aqueous Polyurethane Emulsion
Aqueous polyurethane emulsion adhesive was prepared from polyether toluene diisocynate (TDI) and dimethylol propionic acid(DMPA). The effects of DMPA dosage and the variation of R value(n (NCO)/n (OH)) at a fixed DMPA dosage on the properties of emulsion were determined. Results show that the variation of DMPA dosage and R value has great effects on hygroscopicity, mechanic and thermal properties of emulsion-cast film.
