Abstract

The invention provides a rubber antioxidant, which comprises following components: polybutyl bisphenol, styrenated phenol, tri(nonylphenyl) phosphite ester, potassium disproportional rosin soap, an antioxidant, a catalyst, xylene formaldehyde resin, and a silane coupling agent. The provided rubber antioxidant has the advantages that the toxicity is reduced, the impurity content is low, and the mobility is low. Moreover, the preparation technology is simple, the price is low, the cost is reduced, the product quality is improved, and the economic benefits are increased. The environmental pollution generated by migration of the rubber antioxidant is effectively reduced, the rubber antioxidant is well dispersed in rubber, and the practical effect is good.

Description

technical field [0001] The invention relates to an antiaging agent, in particular to a rubber antiaging agent. Background technique [0002] During the processing, storage and use of rubber and its products, due to internal and external factors, they will gradually become sticky, hard, brittle or cracked. This decrease in physical and mechanical properties and elasticity over time is called aging. With the progress and development of the aging process, the performance of rubber and its products will gradually decrease so that it will completely lose its use value. For this reason, it is necessary to add certain chemical substances to rubber and its products to improve its resistance to the above-mentioned various destructive effects, delay or inhibit the aging process, thereby prolonging the storage period and service life of rubber and its products. The current anti-aging agents on the market use nonylphenol anti-aging agents, which have endocrine disrupting effects and c...
