用于乳聚丁苯橡胶的复配抗氧化剂研究

Important Roles of Compound Antioxidants in the Production and Storage of Emulsion Styrene Butadiene Rubber

采用由抗氧化剂1520+液体亚磷酸酯类抗氧化剂1500的复配协效抗氧化剂体系用于乳聚丁苯橡胶,对于其生产、存储过程提供了优异的耐热氧老化能力,耐热氧老化能力优于单独使用抗氧化剂1520,或者是抗氧化剂SP、抗氧化剂1135与液体亚磷酸酯类抗氧化剂的复配;与抗氧化剂1520和抗氧化剂TNPP的复配物相当。采用抗氧化剂1520和抗氧化剂1500复配而成的抗氧化剂体系不含有具有毒性和污染环境的抗氧化剂TNPP,为E-SBR提供了绿色环保,且具有经济性的抗氧化剂体系。

In the production and storage of E-SBR, the compound of antioxidant 1520 and liquid phosphite ester antioxidant 1500 provide an excellent thermo-oxidative aging protection. Comparing to single antioxidant 1520, single antioxidant SP or compound of antioxidant 1135 and phosphite ester, compound of antioxidant 1520 and 1500 provide a more outstanding thermo-oxidative aging stability. Meanwhile they can be an eco-friendly and economical substitute for antioxidant 1520 and polluting and toxic TNPP for E-SBR.
