Emulsion antioxygen and preparation method thereof

Abstract

The invention belongs to the field of antioxygen, in particular to an emulsion antioxygen and a preparation method thereof. The emulsion antioxygen is emulsified and compounded by the following raw material reagents at the proportion: main antioxygen, auxiliary antioxygen, emulsifying agent, dispersing agent and defoaming agent. The emulsion antioxygen has better oxidation resistance than other similar antioxygens and can achieve the optimal oxidation resistance effect, and the total solid content of the emulsion antioxygen is more than 52%. The emulsion antioxygen has the advantages of good oxidation resistance effect, big activity, low volatility, high durability, no pollution and the like and is especially suitable for protecting tint and pollution-free color polymer thereof. The emulsion antioxygen can be favorably dispersed in ABS (Acrylonitrile Butadiene StyreneAcrylonitrile Butadiene Styre) rubber latex, is ideal antioxygen used preparing ABS by emulsion polymerization and has excellent dispersibility. According to the emulsion antioxygen, the heating oxygen aging time of the ABS resin can be prolonged in the ABS production, the oxidation inducing temperature of the ABS resin is improved, the phenomenon that the ABS resin becomes yellows in the production and processing process thereof can be prevented, the strength of a product can be improved, and the oxidation resistance problem for preparing ABS by emulsion polymerization can be solved.

Description

Technical field:

[0001] The invention belongs to the field of antioxidants, and in particular relates to an emulsion antioxidant and a preparation method thereof. Background technique:

[0002] Antioxidants have gone a long way from production and development to the formation of today's complete working system: the earliest antioxidants used in industry were amines, which were quickly replaced by later sulfur-containing antioxidants due to their strong pollution. Compounds, phosphorus-containing compounds, nitrogen-containing compounds, etc., but because phosphorus-containing compounds have extremely poor hydrolytic stability; and nitrogen-containing compounds have a single effect and are difficult to provide good antioxidant effects, so they cannot become satisfactory for people. Antioxidants, as people pay more attention to the high performance and high value-added ratio of products, in order to endow polymer materials with some unique properties, there are higher and high...
