Description

TECHNICAL FIELD

[0001] The utility model relates to the field of antioxidant reaction, especially an antioxidant reaction device. BACKGROUND

[0002] Antioxidants are a class of chemicals that can delay or inhibit the oxidation process of polymers when only a small amount exists in the polymer system, thereby preventing the aging of polymers and prolonging their service life, also known as "anti-aging agent";

[0003] However, some antioxidants often need to add catalysts during the reaction production process to promote the occurrence of specific chemical reactions and improve the yield. Today's reaction devices directly add catalysts to the reaction raw materials, which leads to uneven contact between the catalysts and the reactants, and requires a certain amount of time to mix completely, which can reduce the efficiency of the reaction to some extent and cause uneven reaction, resulting in a decrease in the quality of the antioxidant.
