Description

technical field [0001] The present invention relates to a compound synthesis device, in particular to a hindered phenol antioxidant 1010 production device. Background technique [0002] Hindered phenol antioxidant 1010 is widely used in thermal processing of polypropylene, polyethylene, polyoxymethylene, ABS resin, etc. It can prolong the service life of plastic products, has low volatility, good extraction resistance, high thermal stability, and long-lasting effect Long, non-coloring, non-polluting, non-toxic. The combination of hindered phenol antioxidant 1010 and antioxidant DLTP, 168 has a synergistic effect. Antioxidant 1010 has very low volatility, is not easy to migrate, and is resistant to extraction. Hindered phenol antioxidant 1010 can effectively prevent the thermo-oxidative degradation of polymer materials during the long-term aging process, and it is also an efficient processing stabilizer, which can improve the discoloration resistance of polymer materials un...
