Amine antioxidants are called blocked amine HALS and have a variety of antioxidants. Blocked amine drugs are generally used in combination with anti-aging agents (such as benzodiazepines, benzophenones, etc.) to achieve better results than when used alone. In order to prevent or inhibit free radical initiation reactions and chain growth reactions, the free radical chain reaction can be terminated to prevent oxidation.
Amine antioxidants are widely used in the rubber industry and are one of the earliest developed antioxidants. They not only have good protection against oxygen, but are also resistant to light and heat. , buckling, copper, etc. play a good protective role.
Aromatic secondary amine derivatives, mainly diaryl secondary amines, p-phenylenediamine, ketamine, aldosterone, etc. Although this antioxidant has antioxidant properties, it is easy to change fat pollution, so the product has more color requirements and uses less materials.
Amine antioxidants are generally divided into antioxidant AW, antioxidant BLE and antioxidant RD.
1. Anti-aging agent AW (acetone and p-amino phenylethyl ether, 6-ethoxy-2,2,4-trimethyl-1,2- Dihydroquinoline)).
2. Anti-aging agent BLE (acetone high temperature condensed diphenylamine) CH3CH3NH.
3.RD (2,2,4-trimethyl-1,2-dihydroquinoline polymer) CH3CH3CH3HNn.
