Method for determinationMethod for determination of effective content and purity of rubber compounding agent

US standards for the determination of the effective content and purity of rubber formulations, ASTM standards for the preparation of p-phenylenediamine antioxidant purity determination methods such as 6PPD, IPPD, 77PD, DTPD and other methods used are gas chromatography and high performance liquid phase Chromatography, sulfenamide-based accelerators, benzothiazole-based accelerators, and Glanidine-based accelerators were determined by high performance liquid chromatography.

Japan's JIS standards in the provisions of the phenylenediamine antioxidant PPD, 4020,4010NA and other gas chromatography and high performance liquid chromatography determination of purity; sulfenamide accelerator CBS, DCBS, DIBS and TBBS by liquid chromatography Determination of purity.

ISO international standards in the PPD class of antioxidant determination method is also specified in the purity of the technical indicators, the same is the use of gas chromatography and high performance liquid chromatography to determine; sulfonamide thiazole accelerator MBTS, CBS, TBBS, DIBS, DCBS and MBS were determined by liquid chromatography.

China's standards in the effective content of rubber with the purity and detection methods, the implementation of the rubber compound with the national standards, industry standards and business standards in the provisions of the majority of inorganic compounds with the effective content detection methods such as sulfur, zinc oxide, calcium carbonate , Silicon dioxide, etc. Determination of chemical analysis is mainly titration analysis. Organic compounds with the effective content and purity of the standard method of detection of less, the current national standards for the detection of anti-aging only in 2007 has just promulgated standards in the purity of p-phenylenediamine antioxidant detection methods, other antioxidants and accelerators There are no standard methods for purity testing. In our contact with some of the tire manufacturers and rubber products companies, even with a mixture of detection means, but basically did not establish an effective content of detection methods, so that meet the national standard indicators of the mixture is still effective content is not enough or not Active ingredient. The imperfect means of detection caused by the current market confusion with China, many products fish.

Taking the anti - aging agent RD as an example to illustrate the imperfections of our standard method. of effective content and purity of rubber compounding agent
