| titleOfInvention | A kind of preparation method of rubber antioxidant |
| abstract | The invention discloses a kind of preparation method of rubber antioxidant, comprise the following steps：(1) age resistor dispersion liquid：P phenylenediamine type antioxidant is added in organic solvent, ultrasonic disperse is uniform under normal temperature, obtains age resistor dispersion liquid；(2) monomer graft reaction：Water and polymerization inhibitor are added in the age resistor dispersion liquid obtained under agitation to step (1), methacrylate-based monomer is added dropwise after stirring, reaction temperature is controlled at 60~70 DEG C；(3) it is aged：After methacrylate-based monomer drips, continue to stir more than 20min, then heat to 80~90 DEG C, the 13h of insulation reaction 11, be cooled to room temperature afterwards, product is obtained after extracting, washing, drying.The present invention is modified p phenylenediamine type antioxidant by GMA, various functions active site is introduced to reach the lifting of combination property, the aging action of p phenylenediamine type antioxidant can not only be ensured, make age resistor that graft crosslinking reaction occur on rubber molecular chain in sulfidation simultaneously, so as to reduce the generation of migration stain phenomenon, vulcanization promotion and reinforcement tool to rubber are greatly improved. |
