1 A new method for preparing rubber accelerator DCBS
   Introduction: The present technology provides a new method for preparing rubber accelerator DCBS, which belongs to the field of rubber accelerator technology. The new method of preparing rubber accelerator DCBS in this technology, the alcohol-water homogeneous solution of M-Na, acid solution, oxidant solution, alcohol solution of dicyclohexylamine as raw materials, oxidation synthesis of rubber accelerator DCBS. the solvent used in this technology method is ethanol solution, dicyclohexylamine dissolved in ethanol. In this way, in the system of aqueous ethanol solution, M-Na, sulfuric acid, oxidant and dicyclohexylamine can form a homogeneous phase, so that the reaction raw materials can be more fully contacted for reaction, and more target products can be formed to improve the yield. This technical method has high product yield, few by-products, high purity and low raw material consumption. At the same time, the difficult components in the wastewater formed after the recovery of ethanol in the mother liquor distillation are reduced, and the pressure of the later water treatment process is reduced.
2 A method for determining the effective purity of rubber vulcanization accelerator
   Introduction: The present technology relates to the technical field of rubber vulcanization accelerator analysis, especially to a method for determining the effective purity of rubber vulcanization accelerator, solving the problem that the existing test methods for determining the effective purity of accelerator and analyzing its effective promotion ability when applied to rubber vulcanization have obvious deficiencies, containing the following steps: 1) preparing standard rubber samples; 2) preparing external standard rubber samples; 3) vulcanization analyzer test; 4) Determine the standard curve regression equation; 5) Calculate the purity of the sample to be tested.
3 Wastewater treatment process for rubber accelerator production
   Introduction: The present technology provides rubber accelerator production wastewater treatment process, including the following steps: Step 1, establishment of co-mingling solution: feed rubber accelerator production wastewater into the reaction tank, then add concentrator, first stir at 1000-1500r/min for 30-40min, and then add 500 -700r/min and continue stirring for 15-25min, then UV irradiation is used to obtain the co-mingling solution. This technology first establishes the co-mingling solution, the co-mingling solution using concentrator and wastewater co-mingling treatment, concentrator using stable water talcum powder aims to improve the stability of organic matter and salt in COD, so that it is not easy to be evaporated out, the added raw materials such as cerium nitrate aims to activate the contact effect of concentrator and wastewater, the added polyvinylpyrrolidone, aluminum silicate solution, aims to enhance the stability of the reaction system of the co-mingling solution.

5 Detection method of multiple vulcanization accelerators in rubber
   Introduction: This technology provides a method for the detection of multiple vulcanization accelerators in rubber, which includes the detection of four types of vulcanization accelerators, namely MBT, CZ, DCBS and TBBS, in rubber samples. Through acetone extraction and HLB column purification, most of the impurities in the matrix are removed, so that no impurity peaks interfere with the detection of vulcanization accelerators during FID detection. The method has good accuracy, and is fast, automatic and practical; it complements the gaps of the existing technology.
