Preparation and Properties of Anionic Water-Dispersed Polyurethane Containing Polypropylene Glycol and Casein

In this study, analyzed the changes occurred after adding casein emulsions to water -dispersed polyurethane using polypropylene glycol (PPG). For this purpose, anionic water -dispersed polyurethane containing PPG, IPDI and DMPA and casein emulsion prepared by dissolving casein in distilled water using ammonia water were prepared. As a result of measuring the alkali resistance by using the prepared resin, there was no change in the physical properties. The tensile strength of the sample having a high casein content was measured to be 2.227 kgf / ㎟. Elongation was measured at 474% for samples containing less casein and The abrasion resistance was measured as 46.090 ㎎.loss of sample containing much casein as a result of the surface roughness measurement.
