Abstract

The invention provides a liquid antioxidant pre-dispersed master batch. The master batch is prepared by mixing 18-61% of graphene loaded nickel powder, 1.5-3% of polyoxyethylene castor oil, 0.5-6% ofazodicarbonamide, 5-30% of mixed glue, 0.01-8% of a dispersant and 10-80% of a liquid antioxidant. The master batch provided by the invention contains the liquid antioxidant, so that the dispersibility of the antioxidant is facilitated, dust hazards caused by powder antioxidants are avoided, and the operation is simple and convenient. The invention solves the defects of uneven dispersion of antioxidants, dust pollution and poor compatibility among various materials, and the produced antioxidant pre-dispersed master batch has good antioxidant performance, good dispersibility and excellent processability.

Description

technical field [0001] The design of the invention belongs to the technical field of polymer materials, and in particular relates to a liquid anti-oxidation pre-dispersed masterbatch. Background technique [0002] During the processing, storage and use of rubber and its products, due to the comprehensive action of internal and external factors, the physical and chemical properties and mechanical properties of rubber will gradually deteriorate until the final loss of use value. In order to inhibit or delay the aging process, it is necessary to add Antioxidant (antiaging agent). [0003] The existing method of adding antioxidants is to directly add antioxidants to rubber. Although the operation is simple, the dispersion of antioxidants in raw rubber after mixing with raw rubber is poor, so it is urgent to masterbatch antioxidants This is not only beneficial to the dispersion of antioxidants but also can increase the compatibility between related processing materials. [0004...
