Abstract:A new hydrogen peroxide （H2O2） stabilizer was prepared by using maleic acid-acrylic acid copolymer （MA-AA） as the main stabilizer and compounded with chelating co-stabilizer. The stability of the composite stabilizer for H2O2 bleaching was studied by measuring the chelating ability of metal ions， the decomposition rate of H2O2 and the H2O2 bleaching experiment of chemi-mechanical pulp， and the performance of the composite stabilizer was compared with that of the imported stabilizer. The results showed that the chelating capacity of Fe3+， Mg2+， Mn2+， Ca2+of the new H2O2 stabilizer reached 262.3， 105.2， 141.4， 160.3 mg/g， respectively. Under the condition of simulating the different metal ion contents in the water of four regions in China， the new H2O2 stabilizer could effectively inhibit the decomposition of H2O2， and had the same stability ability as the imported products. Under the condition of industrial pulp bleaching process， the compound stabilizer had good bleaching effect on eucalyptus， poplar， bagasse， and reed chemi-mechanical pulp at low dosage.
