Abstract:Collagen extracted from leather wastes was modified with vinyl monomers to prepare a new collagen emulsion in this work. The grafted groups on collagen were characterized by FTIR, particle sizes distribution of the modified product was tested by instrument of laser particle size distribution, the thermal stability of the product was studiied by TG. The modified collagen emulsion was applied together with gelatinated starch or commercial styrene acrylic emulsion was corrugating paper sizing agent. The mechanical and water proof properties of the paper samples were investigated, and the sizing results were compared with that of the mill’s sized paper samples.
