purpose | the product is a polluting antioxidant, in addition to good Antioxidant efficacy, and anti-ozone, anti-bending to find the role of cracking and inhibition of copper, manganese and other harmful metals. Its performance is similar to that of antioxidant 4010NA, but its toxicity and skin irritation are smaller than 4010NA, and its solubility in water is better than 4010NA (water loss rate: 4010NA is 50%, and 4020 only 15-20%). Can be widely used in the preparation of tires, tape and many other industrial rubber products, the general dosage of 0.5-1.5%. This product is not suitable for making light-colored products due to serious pollution. Antioxidant 4020 is one of the main varieties of p-phenylenediamine antioxidant. P-phenylenediamine antioxidant is the main good varieties commonly used in rubber industry at home and abroad, and it is also the development direction of antioxidant in the future. It is an antiozonant and antioxidant for natural rubber and synthetic rubber, and has excellent protective effect against ozone cracking and flex fatigue |
production method | a variety of methods can be used to prepare antioxidant 4020. Generally, 4-aminodiphenylamine is obtained by catalytic hydrocondensation with methyl isobutyl ketone. N-(1, 3-dimethylbutyl)-p-aminophenol can also be used to react with aniline at 210-230 °c under the catalysis of iron powder and iodine (or FeCI2, FeCI3), after the condensation reaction is completed, the mixture of the product is obtained by distilling off the volatile substances at 180 ° C. (133 Pa), which is divided into: N-(1, 3-dimethylbutyl)-N'-phenyl-p-phenylenediamine 50%,N,N'-diphenyl-p-phenylenediamine 17.5%,N,N'-bis (1, 3-dimethylbutyl)-p-phenylenediamine 13.4%. |
