Hydrocarbons such as rubber, plastic polymer material by oxygen, heat, light (especially ultraviolet rays), metal ion or a dynamic role of fatigue prone to oxidative aging in its storage, transport and use of the process requires a certain amount of antioxidant. Traditional styrene-butadiene rubber condensation process to join about0.3-0.58PPD as storage and transportation antioxidant, due to the the rubber process trace nitrosamine carcinogen8PPD cause, by the criticism. The EPPD is the new generation of green rubber antioxidant, with its production of environmentally friendly the SBR PSBR1500E product performance in line with the requirements of European exports.Is an R-aryl group-phenylenediamine, R’-aryl group-phenylenediamine compound was due to the introduction of the R and R’groups, so that the product, adding rubber reportedly EPPD does not produce the nitroso compound. Detailed analysis of the antioxidant EPPD the R and R’group specific component and other components, scientific and rational adjustment formula, it is particularly necessary to ensure the smooth running of the rubber production and product quality.Lanzhou Petrochemical Company100,000tons/year styrene butadiene rubber plant put into operation since the eco-friendly antioxidant the obvious loss phenomenon to cause a significant adverse effect on the quality of the styrene-butadiene device sewage. At the same time lead to fluctuations in the antioxidant content of rubber products, the impact of the anti-aging properties and mechanical properties of the product, thereby affecting the marketing of environmentally friendly styrene-butadiene rubber.In this paper, through literature research to determine of domestic environmentally friendly styrene-butadiene rubber antioxidant active ingredient and its amount; ESI mass spectrometry and HPLC analysis of environmental protection styrene butadiene rubber SBR1500E, with antioxidant EPPD component. The amount of antioxidant properties of rubber. The effects of the rubber antioxidant pool water COD. Through experimental studies to determine the optimal dosage of environmentally friendly antioxidant; through process optimization to reduce the loss of environmentally friendly antioxidant; and then guide the industrial production of environmentally friendly antioxidant optimum dosage conditions, the mechanical properties of the rubber meet the appropriate grade technical requirements.
