Study on New Technology of Hide Glue Modification

Yu Lili,Li Zhongjin,Song Liang,Cheng Lei(College of Chemistry and Chemical Engineering,Shaanxi Universityof Science & Technology,Xi’an 710021,China)  
A new technology of hide glue modification was introduced which was grafted by epoxy chloropropane.The influencing factors were analyzed,such as water/adhesive ratio,the acid decomposition temperature,the quantity of acid,the copolymerizing temperature and the quantity of epoxy chloropropane,and the optimal technology was obtained.The freezing point and the molecular weight distribution of hide glue before and after modification were compared.The reaction mechanism of this reaction was studied through infrared spectra(IR),differential scanning calorimetry(DSC),thermal stability test,the first adhesive strength and tensile shear strength.The modified hide glue has low freezing point and high adhesiveness.
