Hindered phenol antioxidant and synthesis method thereof

Abstract

The invention provides a hindered phenol antioxidant and a synthesis method thereof, and relates to the technical field of antioxidants. The hindered phenol antioxidant is prepared from the followingingredients in parts by weight: 10-30 parts of 2, 6-di-tert-butyl-4-nitrophenol, 0.3-0.9 parts of potassium hydroxide, 0.1-0.3 parts of ferric chloride, 50-100 parts of absolute ethyl alcohol, 3-4 parts of organic zinc, 1-2 parts of phosphite ester compounds and 4-6 parts of a light stabilizer. An antioxidant is synthesized from the raw materials such as 2, 6-di-tert-butyl-4-nitrophenol, potassiumhydroxide, ferric chloride, absolute ethyl alcohol, organic zinc, phosphite ester compounds and the light stabilizer, so that the hindered phenol antioxidant synthesized by adopting the method is diversified in performance, the use effect is obviously improved, and after the hindered phenol antioxidant is matched with a high polymer material for use, the tensile property and the bending resistance of the high polymer material can be enhanced.

Description

technical field [0001] The invention relates to the technical field of antioxidants, in particular to a hindered phenolic antioxidant and a synthesis method thereof. Background technique [0002] In recent years, my country's plastics industry has developed rapidly, and the demand for plastic additives is also increasing year by year. As an important polymer material additive, there has been a great increase in both quantity and variety. The synthesis technology of antioxidants is subject to industrial The phenolic antioxidants 264 and phenylethylated phenol developed in the early stage have poor effects on the one hand, and on the other hand, they have been found to have potential toxicity and are gradually only used in the rubber industry with lower requirements. [0003] At present, there are many types of antioxidants synthesized in various ways, which are used in a wide range of fields. However, many traditional antioxidant synthesis methods are relatively simple, and th...
