Abstract

The invention relates to a rubber anti-aging agent composition and belongs to the field of rubber preparation.The rubber anti-aging agent composition aims at overcoming the technical defects that a great number of existing rubber anti-aging agents are toxic and poor in storage stability.The rubber anti-aging agent composition is prepared from active components, including 10-12 parts of zinc stearyl lactylate, 6-15 parts of poly butyl bisphenol, 40-50 parts of tri (nonylphenyl) phosphite ester, 3-8 parts of disproportionated rosin potassium soap, 2-7 parts of N-isopropyl-N'-phenylenediamine, 5-10 parts of vinylation phenol, 5-10 parts of xylene formaldehyde resin, 8-12 parts of 5-(3, 5-bi-tert-butyl-4-hydroxy-benzyl)-1, 3-dimethyl pyrimidine-2, 4, 6 (1H, 3H, 5H)-triketone and 5-8 parts of an anti-aging agent.The rubber anti-aging agent composition is excellent in aging resistance and quite suitable for being applied and popularized in the rubber industry.

Description

technical field [0001] The invention relates to a rubber antiaging agent composition, which belongs to the field of rubber preparation. Background technique [0002] During the processing, storage and use of rubber, due to the comprehensive influence of internal and external factors, there will be aging phenomena such as softening, stickiness, hardening, cracking, brittleness, spots, mildew, loss of luster, color change, etc. Rubber anti-aging Antioxidant is a substance that prevents or delays the aging of rubber. The anti-aging agent began to be produced and applied in the 1930s. Because it can effectively prevent the aging caused by thermal oxygen aging and flex fatigue, and its price is low, it is used in a large amount in the rubber process. However, many existing rubber antioxidants are toxic and have poor storage stability. They will change from white to grayish black when exposed to air and sunlight. During the use of rubber products, especially under the action of ...
